Inventory Reduction Table
Example. Shown below is how one manufacturer of small screws reduced his inventory of C-1018 wire from 24 different sizes
to only seven stocked sizes. The first thing he did was to list his required wire diameters (rounded off to the nearest even dimension) as follows:

His specific products required limiting the maximum area reduction to about 20%. He immediately realized several advantages.
1. He was able to reduce his stock-sized inventory down to just seven basic sizes.
2. He was able to induce his steel suppliers to eliminate the surcharge for “special tolerance” wire.
3. In most cases he was able to purchase annealed-in-process wire and impose the final draft in-line with the cold headers—thus
eliminating the steel supplier’s charge for this finishing draft. (See chart on reverse side.)

Notes: 1. Prices vary from region-to-region, from steel company to steel company, and from mill to mill, but are approximate
ly correct from a relationship standpoint (comparing condition to condition).
2. Considerable potential savings can be negotiated when wire is procured from the steel company in the semi-finished form or condition, i.e. initially drawn to rough tolerances at the steel company, shipped to the customer in a semifinished form, and the light finishing pass drawn in-line.

The operation of a capstan-type in-line
wire drawer is dependent on one thing:
traction. The force required to pull the
wire through the drawing die is imparted to the wire by traction on the capstan
and the machine’s ability to provide this
traction is dependent upon several factors.
The principle involved with developing
traction is that of a spring clutch a coil
spring around a rotating shaft. When
the exiting end of a spring is pulled, its
inside diameter decreases and comes in
contact with the rotating shaft.
The ensuing traction transmits torque
from the shaft to the spring which
rotates along with the shaft. Increasing
the number of loops of wire wrapped
around the capstan, or increasing the
diameter of the capstan improves the
traction. Also, increasing the exiting
tension of the wire as it leaves the capstan, increases the traction.
Capstan Traction with a
Wire Relaxer
Capstan Traction and the
Compensator Arm
The Wire Relaxer, a grooved one-way
clutched roller, is used to continuously
clamp the the last loop securely against
the capstan and prevent the wire from
springing away. Therefore, with a given
capstan diameter, greater traction can
be developed allowing heavier drafts or
larger wire sizes. Additionally, the Wire
Relaxer serves to reduce the exiting tension, resulting in the following benefits:
Since almost all wire production
machines (cold headers, bolt makers,
multi-slide units, and straightening and
cutting machines) consume wire intermittently, using a feed-and-dwell cycle,
a buffer must be provided during the
dwell portion of the cycle. If this is not
done, exiting tension will be lost resulting in a loss of traction.
1.Safe removal of the gripper chain
during set-up.
The compensator arm functions
primarily to:
2.The amount of pressure applied to the compensator arm can be reduced,
which prevents wire kinking.
1.Provide loop storage so that the
production machine can feed-and
dwell while the wire drawer operates
continuously.
3.With reduced compensator arm
pressure and with reduced exiting
tension, short feeds on the production
machine are virtually eliminated.
2.Maintain just the right amount of pull
or exiting tension to insure proper
traction with minimal wire slippage.
3.Using AUTODRAW®, RMG’s
unique Automatic Speed Trim
Control system, it automatically
increases or decreases the speed of
the wire drawer so that it exactly matches the speed of the production machine.
If the exiting tension is not sufficient to
keep the wire tightly wrapped around
the drum, traction will be lost. This is
why the relationship of the wire diameter and the capstan diameter is important. Large-diameter and/or high-tensile
wire resists bending and tends to spring
away from the drum. Small diameter
and/or low-tensile wire clings more easily around the capstan’s surface.

How an RMG In-Line Wire
Drawer Works
2.1
Fastener Industry
Application
Wire Drawers
Ten ways your company can use In-Line Wire Drawing to Lower Material
and Manufacturing Costs as well as Improve Product Quality and
Productivity
1. Lower Material Costs
Using hot-rolled rod (for any wire
diameter .218” (5.5 mm) and larger)
and/or semi-finished wire will give
your company a competitive edge and
improve profits.
2. Utilize Just-In-Time Inventory
An in-line wire drawer at the point of
wire consumption is the ultimate in
JIT inventory management. By careful
selection of parent diameters and drawing many different sizes from a few
stock sizes, inventory dollars can be
reduced considerably.
3. Provide Exact Diameter Control
2.2
An in-line wire drawer provides the
perfect diameter at the point of
use, consistently, from coil-to-coil.
Consistent volume control depends
upon exact diameter control.
4. Improve Metal Formability
Freshly drawn wire is easier to form
and the heat generated by the drawing process improves the cold forming
process. Many difficult cold-headed
specials cannot be produced without
utilizing a wire drawer.
5. Improve Tooling Life
Parts produced using freshly drawn
wire require less forming force, thereby
improving tooling life.
In addition, consistent volume control
means consistent heading tonnage
which, in turn, consumes less tools.
6. Improved Wire Surface
Conditions
The surface of wire drawn in-line
has no chance to rust or deteriorate.
Additionally, you can control the quality, type and amount of wire lubricant in
your own production process.
7. Eliminate Short Feeds Before
They Occur
RMG’s AUTODRAW Speed Control
System matches the consumption rate of
the production machine. All tension is
removed from the feed rolls.
Also, STARTGARD, SLIPGARD and
TANGLEGARD sense any problem
with the process and stop the production
machine before a shortfeed occurs.
8. Eliminate Wire Kinks
Wire drawn in-line is always smooth
and straight with no kinks and of the
highest quality.
9. Employ any Coil Size or Weight
An RMG wire drawer does all the work
of turning the coil, eliminating the load
on the feed rolls, regardless of coil size.
10. Increase Overall Performance
When you consider the improvements
associated with an RMG machine in
regards to material cost, tool usage,
coil change time and the ability to use
larger coils, it’s easy to understand why
a header utilizing an RMG in-line wire
drawer will outperform one that doesn’t
in both cost and consistency of product.

Wire Products Application
Here’s how your company can use In-Line Wire Drawing to Lower
Material and Manufacturing Costs as well as Improve Productivity and
Product Quality
2.3
AUTODRAW®
Draw Box
Utilized with both variable frequency
and hydraulic drives, AUTODRAW is
the automatic speed control system for
in-line wire drawing developed by RMG
in 1982. AUTODRAW eliminates the
necessity of precisely hand-regulating
the capstan speed to the wire consumption rate of the production machine.
Utilizing the AUTODRAW system, the
capstan speed automatically matches
the wire speed. All control functions
are automatically executed starting
and stopping whenever the production
machine starts and stops.
Large capacity powder box may be
used for either wet or dry lubricants. On
Models 12 through 910, the draw box
is inclined to prevent spillage of liquid
lubricants
and is
provided
with a
gasket for
sealing the
die end of
the draw
box. The
draw box is set up for 3” (75 mm) diameter die casings. Bushings are available
for smaller dies. On the Model 1011
and larger machines, the draw box is
horizontal and is equipped with a return
port for circulating liquid lubrication
systems. These larger models are set
up with a 5” (125 mm) die pocket to
accommodate larger dies and pressure
holder die assemblies. All draw box
entrances are set up to accept an old
draw die as an entrance guide bushing.
Additionally, all RMG draw boxes come
with a clear plastic cover for housekeeping purposes.
RMG’s Patented Wire Relaxer
The Wire Relaxer is a grooved, oneway clutched roller used to continually
clamp the last loop of wire around the
capstan. It keeps all the loops tightly
wrapped around the capstan, and prevents the wire from springing away.
Greater traction can be developed with
a given capstan diameter. This allows
heavier drafts or larger wire diameter to
be drawn with little or no wire slippage.
This feature also keeps the wire firmly
in place while allowing safe removal of
the gripper chain.
Machine Enclosures
Utilizing single side panels, as well as
access doors
when necessary, all
RMG
enclosures
are easy to
remove for
periodic
service.
Smooth
enamel
finishes
contribute to reduced housekeeping and
maintenance expenses.

TANGLEGARD
2.4
Electrical Interconnects
These three unique control features stop
short feeds before they occur:
STARTGARD prevents starting of the
production machine if the operator has
forgotten to place the wire drawing
machine in a ready condition.
SLIPGARD signals the production
machine to stop if the capstan cannot
produce wire as fast as required.
TANGLEGARD provides a signal to
stop the production machine if a tangle
develops on the uncoiling unit and the
wire drawer moves.
Variable Frequency (VF) Drives
Variable frequency drive technology
provides smooth, maintenance-free,
fully-automatic speed control and is
available on all RMG Wire Drawers.
Hydraulic Drives
RMG’s fully-automatic hydraulic
drives are designed and built by RMG
and include many features normally
associated with heavy-duty hydrostatic
transmissions including forced-cooling,
filtration, low fluid level protection, and
dynamic braking. All low-maintenance
RMG hydraulic drives have an infinite
speed range from zero to maximum
speed.

Operating Controls
All RMG Wire Drawers are equipped
with pushbutton controls and pneumatic
regulators for ease of operation and
adjustment. All controls are conveniently placed for easy access. Larger models
are equipped with swing-arm pushbutton pendant.
Pneumatic Systems
Spacesaver Configuration
The main components of an RMG
pneumatic system include pneumatic
cylinders, valves, solenoids and regulators.
RMG Wire Drawer Models 12-89 are
available in the Spacesaver configuration which provides an integral turntable
either behind or on top of the machine,
depending on space requirements.
All cylinders used on RMG machines
are provided with lifetime lubrication. Field lubrication is not required.
Pneumatic cylinders are used to load the
compensator arm and Wire Relaxer on
any machine equipped with a 10hp (7.5
kW) or larger motor (smaller machines
use springs for loading these devices).
Wire relaxer pneumatic systems are
designed to maintain pressure even
when the air supply is shut off.
All Spacesaver versions include the
TANGLEGARD snag detection system.
Standard pneumatic equipment includes
an air filter, and each actuator is
equipped with its own pressure gage.

Pressure Die Adaptors and Holders
Hardened Rod Guide Ring
Annular Roller Assembly
Pressure dies are a wire drawing aid
that, during the drawing operation,
force lubricant under high pressure onto
the wire surface. Pressure dies help to
establish better lubricant coating and
maintain that lubricant film in subsequent drafts.
The optional rod guide ring is often
specified when the wire drawing
machine is intended to be used with
flippers or wherever there is a possibility of badly kinked rod approaching the
entrance of the wire drawer.
These roller assemblies are helpful in
guiding the rod into the draw box,
minimizing damage to the rod. This is
especially important on applications
involving extruded parts, which can
be very sensitive to variations in the
amount of lubricant on the wire.
Pressure die holders are a simple method of introducing the pressure die/drawing die combination in a wire drawing
operation. The pressure die is before the
drawing die. With a slightly tapered outside diameter, the pressure die holder is
accurately aligned and firmly held in the
die box. It can be introduced into most
die boxes with a minimum of fitting.

Electrical Interconnects
These three unique control features stop
the production process if a problem
occurs:
TANGLEGARD provides a signal to
stop the production machine if a tangle
develops on the uncoiling unit, causing
the wire drawer to move.
STARTGARD prevents starting of the
production machine if the operator has
forgotten to place the wire drawing
machine in a ready condition.
SLIPGARD signals the production
machine to stop if the capstan cannot
produce wire as fast as the machine
requires.
Wire Relaxer Assemblies
Pneumatic Type Single
Patented RMG Wire Relaxer Assemblies
include a grooved roller which is
equipped with a non-reversing bearing,
which firmly holds the last loop of wire
on the capstan’s
surface. This nonreversing bearing
prevents the wire
from “backing-up”
on the capstan, which
reduces the pull-back
on the wire entering the production
machine. This feature
also keeps the wire
firmly in place while removing the gripper during set-up.
This is a cylinderactuated assembly
(usually used with
wire sizes larger
than .280”/7.0
mm) used only on
Models 56 and 67.
On the Model 67
it is furnished as
standard, and is an
optional assembly on the Model 56.

and rod the ability to cut their raw
material with the following advantages:
Performing the same task as on the largest wire drawers, this unit enables the
operator to straighten and advance the
wire, to the next operation, at the push
of a button.
Safety - Cut end simply drops off safely
and easily compared to chisel-type cutters.
Ease of Operation - Cutters develop
tons of shear force with hand-operated
hydraulic pump.
Improved Shear Quality - Overlapping
blades with full-radius contour provides
improved shear surface.
Convenience - The Huskie Cutter
eliminates the need for an electrically
operated power pack.

RMG Pointing Equipment
Pointing Equipment
It is always necessary to provide a
pointed end when setting up a wire
drawing machine. Although butt-welding a slightly smaller wire to the heead
end of the wire to be drawn represents
one common method of providing the
pointed end, under some circumstances
it is more practical to use a pointer. This
technique “necks down” a section of the
parent wire and permits it to be inserted
through the drawing die for initial set
up. For small wire sizes, .060” (1.5 mm)
to .250” (6.4 mm), two common methods are pull pointing and roll pointing.
Pull pointers can be mounted on each
wire drawer but, because the capstan is
used to power the pointer, pull pointers
interfere with production. Roll pointers stand alone allowing the wire to be
pointed ahead of string-up and, one unit
can service several wire drawers.
For medium wire sizes, .250” (6.4 mm)
to .500” (12.7 mm), the pull pointer is
a good inexpensive method because
it uses the capstan to provide the
substantial pull required. However,
as mentioned before, the pull pointer
interrupts production.
For large wire sizes, .500” (12.7 mm)
to 1.00” (25.4 mm), the self-contained
hydraulic push pointer will provide the
power necessary, and pointing can be
accomplished “off-line” as with a roll
pointer.

1. The head end of the wire is inserted
through the Type RA pointer assembly.
The gripper is attached to the wire.
2. The machine is jogged and about
6” (150 mm) of wire is reduced to a
diameter about .006” (.15 mm) to .010”
(.25 mm) smaller than the finished wire
diameter.
3. The reduced portion is cut with bolt
cutters before removing the gripper
chain and before removing the wire
from the pointer assembly. Any
residual fins are removed by filing.
4. This operation results in a reduced
diameter on the head-end of the wire,
which can be inserted through the drawing die.

Material costs usually constitute over 50% of the total manufacturing costs.
These costs can be cut 20% by mechanically descaling in-house.

Economic Considerations
Almost all wire products are produced
from coiled wire drawn from either
chemically or mechanically descaled
rod. Due to economic and environmental considerations chemical descaling
(pickling and liming) has become a
thing of the past, with two possible
exceptions:
Almost any company that purchases
cold-drawn wire can lower costs and
improve productivity by procuring inexpensive green (non-descaled) rod and
producing their own cleaned and drawn
wire in-line with their existing production process. Two immediate cost benefits will be realized:
1. Cold-heading-quality wire which requires an extremely clean surface for enhancing the extrusion process.
1. Material costs can be cut 20%.
2. Plating-quality wire which requires an extremely clean surface for elec tro-chemical bonding, and appear-
ance purposes.
Virtually all other wire products can,
and should, be produced from mechanically-descaled material especially parts
that are subsequently plastic coated or
painted.
Mechanical descaling can be accomplished either at the wire mill or, better yet, immediately before the wire is
converted into its final or semi-finished
form. The problem of providing suitable
coatings or corrosion resistance when
descaled and drawn wire is produced at
a remote wire mill precludes procuring
mechanically-descaled wire from these
commercial mills. Therefore, the most
practical method of producing this material is just before the wire is converted
into a straightened, formed, or welded
part on site. This especially applies
when wire diameter is .218” (5.5 mm)
and larger which permits combination
single-hole drawing and descaling.
2. Since rod coils are usually available in weights that are double the weight of wire coils, the production process can become much more efficient because of the longer sustained pro-
duction runs with minimum time lost for coil changeover.
Reverse-Bending Mechanical
Descalers
There are two principle methods of
mechanical descaling: Shot-blasting and
reverse-bending.
Shot-blasting is usually confined to rod
diameters larger than .625” (16 mm).
Reverse-bending the rod is predominantly done on rod diameters less than
.625” (16 mm). This simple process
employs, in most cases, two sheaves
oriented at right angles to each other.
The rod is pulled over and through the
sheaves which causes reverse flexing
and both compresive and tensile bending on all four sectors of the rod.
The combination of the reverse bending
and stretching forces causes the rod to
severely elongate and, in fact, it is this
elongating process that causes the scale
to break away from the surface of its
steel parent. Steel is relatively elastic;
the laminar ferrous oxide scale is almost
completely inelastic and easily fractures
and falls away from the rod.
The amount of scale, and the strength
of the bond which holds it to the rod’s
surface, varies with the rod mill’s manufacturing practices and is controllable.
It is important to tell your rod supplier
that you plan to mechanically-descale
the rod. The mill can then contribute
to somewhat easier scale removal by
controlling rod production time and
temperatures. Keeping the rod’s surface
dry and storing indoors also facilitates
scale removal.
The amount of elongation imposed
on the rod as it traverses through the
descaler is a direct function of the
pitch diameter of the reverse-bending
sheaves. Scale starts to break loose at an
elongation of about 5%. At 8% to 9%
most of the scale has broken off.
Cleaning Techniques
The breaker rolls can only reverse-bend
the wire. Residual dust and scale must
be cleaned off the rod before descaling
is considered complete. The “air wipe”
method using a carbide-inserted guide
assembly has proven to be the most economic and effective method of surface
dust removal. Using an exiting air-wipe
assembly and a liquid lube box on the
wire drawing machine provides the best
combination for effectively cleaning
the material especially when the lube
system includes a recirculating pump,
a particle settling tank, and a filtering
system.

General Specifications
The RMG MD-10 Mechanical Descaler
provides the industry’s simplest and
most practical system for scale breaking
and removal. The MD-10 consists of
four principle parts:
1. An entrance guide assembly with hardened guide rollers.
Descalers
2. A two-roll reverse bending assembly with replaceable carbide inserts.
3. A carbide-inserted air wipe assembly for blowing off residual dust. Air consumption is very low. When used with a wire drawer, an electrically- interlocked solenoid valve is provided which automatically shuts off air supply when the wire drawer stops.
4. A hinged, covered enclosure with facilities for connecting to a dust collecting unit for accumulation and removal of scale.
The MD-10 accommodates two rod
diameter ranges: 7/32” (5.6 mm) to
9/32” (7.1 mm) using 2.5” (63.5 mm)
pitch-diameter breaker rolls and 9/32”
(7.1 mm) to 13/32” (10.4 mm) using
3.25” (82.5 mm) diameter breaker rolls.
The MD-10 descaler is designed to be
used with RMG in-line wire drawers
that have provision for attaching the
descaler. Existing wire drawers can be
modified in order to accept a descaler.
RMG’s Model 67 28” (700 mm)
capstan wire drawer is used, in most
cases, to provide the tractive drawing
force for pulling the rod through the
descaler’s breaker rolls and for drawing
the wire. However, on relatively slowspeed applications of about 100 fpm
(31 m/min) and slower, it is possible to
adapt a smaller Model 56 (24”/600 mm
capstan), providing the wire diameter
after drawing will be under .200”
(5.0 mm).
Simplicity and Ease of Set-up: designed
to permit the operator to set-up the
machine quickly and easily.
Easy Scale Removal: for either dumping into tote pans or for use with central
station scale-handling and dust collecting equipment.

And, for Complete Wire Products Applications...
…here’s how your company can use RMG In-Line Wire Drawers with LEWIS Straightening & Cutting Machines to lower
material and manufacturing costs, as well as improve productivity and product quality:
Lower Material Costs
Reduce Pull Back on Feed Rolls
Descaling hot-rolled rod, or drawing
semi-finished wire in-line, will drastically reduce your material costs,
therefore improving profits and giving
your company a competitive edge.
System matches the consumption rate of the production machine. All tension is removed from the feed rolls.

associated with using RMG machines
in regards to material cost, tool usage,
coil change time and the ability to
use larger coils, it’s easy to understand why a LEWIS Straightening &
Cutting machine utilizing an RMG
In-Line Wire Drawer will outperform
one that doesn’t…in both cost and
quality of product!
Regardless of coil size an RMG wire
drawer does all the work of turning the
coil, eliminating the load on the feed
rolls.

Uncoiling

RMG
Payoff Equipment
5.1
Three uncoiling methods are used to
payoff rod and wire:
Turntables, flippers and power-driven
uncoilers. Following are specifications
for use of each method:
Turntables
Diameter range:
Up to .500” (12.7 mm)
Material: Wire or rod
Flippers
Diameter range:
.218” to .625” (5.5 to 16 mm)
Material: Rod only
Power-Driven Uncoilers
Diameter range:
.500” to 1.75” (12.7 to 45 mm)
Material: Wire or rod
Turntables
Turntables represent the most commonly used method of payoff for all
wire and rod sizes up to 1/2” (12.7 mm).
Relatively low in cost, turntables facilitate material storage and handling. They
require a minimum amount of floor
space. The only disadvantage associated
with turntables is that the entire production process must be stopped during
coil changeover. This is not a serious
consideration on applications involving
wire sizes smaller than 1/4” (6.3 mm).
However, on larger diameter applications the downtime associated can be a
serious consideration particularly with
high-speed headers or straightening and
cutting machines.
Flippers
Flippers are ideally used for rod sizes up
to 5/8” (16 mm). Downtime due to coil
changeover can be completely eliminated by using double-end coil stands or
flippers. Since the coil is stationary and
not rotating, the end of the active coil
can be butt-welded to the beginning of
the standby coil.
When the active coil is depleted, the
operator rotates the flipper so that the
standby-coil becomes the active coil,
allowing continuous operation of the
wire drawing machine and production
machine.
Flipping is limited to applications
involving the payoff of hot rolled rod
into an in-line wire drawer. Flippers
require more space than turntables but
on certain higher speed applications, the
advantage of being able to enjoy continuous parts
production outweighs the floor space
consideration.
Power-Driven Uncoilers
Power-driven uncoilers represent the
best payoff method for uncoiling large
diameter stock 1/2” to 1-3/4” (12.7 to
45 mm).
Equipped with power-driven feed rolls
and a straightener, these uncoilers
pre-feed and prestraighten the stock,
enabling the operator to get the end of
large diameter material to the next
operation at the push of a button.
They also sense the coil condition and
power rotate the coil, when necessary,
maintaining a smooth material flow.
Welding
Butt welding is an integral part of the
wire production process. Joining the end
of one coil to the beginning of the next
coil eliminates the need to restring the
wire drawer. When flipping, this is done
while production continues. With the
use of a turntable, although production
must cease, welding is still an advantage to avoid having to restring the wire
drawer.
In all cases, the actual weld is removed
during the production process. Welding
can aslo be used as a pointing tool for
large diameters, if desired.
Pointing
In setting up a wire drawing machine,
it is necessary to provide a pointed end
on the wire or rod. This pointed end is
inserted through the drawing die and
clamped by a gripper chain which is
used to wrap the capstan with the wire.
Uncoilers/Payoff
Equipment
Uncoiling
One of the best methods of providing
this pointed end is to simply butt-weld a
slightly smaller length of wire, about 6”
to 8” long, to the head end of the coil.
Applications involving smaller wire
diameters usually do not require butt
welding. Alternative pointing methods
are:
1. Pull pointing.
2. Roll pointing.
3. Push pointing.
4. Grinding.

5.2 General Notes
4. Floor plan layouts shown here rep
resent right to left wire flow, which usually applies only to cold heading applications. Straightening and cutting machines and some other applications use a reverse layout.
2. Dimension G assumes feed roll height is equal to draw box height H.
If feed roll height is lower than H, add 4” (101.6 mm) to G for each one inch that feed rolls are lower than H.
1. Suggested distances between machines and payoff units should
be regarded as approximate. RMG’s estimates have taken into consideration wire and rod diameters, wire speed, ease of set-up for operator and wire behavior with respect to both diameter and stiffness.
3. For high speed applications (higher than 150 fpm/45.7 m/min.) distance JJ should be increased. Submit all details to RMG for recommendations.

Benefits
Reduced downtime
A power-driven uncoiler prefeeds and
prestraightens the stock, and delivers it
over into the feeding mechanism of the
cold former, with less downtime and
with the quickest possible coil changeover. And, when it comes to reducing
coil changeover time no other method
can match the efficiency of an RMG
power driven uncoiler.
Reduced Load on the Feed Rolls
The uncoiler’s ability to reduce the
coil’s load on the feeding mechanism
reduces the possibilities of short feeds.
This is accomplished by:
• continuous (adjustable speed) or intermittent power-driven coil rota-
tion.
• built-in snag switch for the “bound
coil” condition.
• rugged RMG coil splitter rollers reduce coil tangling.
Reduced Manpower
Power driven uncoilers provide the most
efficient, safest and easiest method of
handling large diameter coils. One man,
with the aid of only pushbutton controls,
can load large coils.
Safe Operation
Uncoilers/Payoff
Equipment
6. Air actuators for engaging feed rolls are located at back of unit, out of harm’s way.
Every aspect of coil handling is
improved when an RMG power-driven
uncoiler is used. Straightening the
tail end of the stock when the coil is
depleted is easily done. Operator fatigue
is minimized and the possibility of accidents is reduced. General Specifications for RMG Power-Driven Uncoilers

5.4
Typical Model Designation
Transmission Equipment
20 24-01
Fixed Speed (-01 Designation)
Standard (-01) models use a TEFC
motor and worm gear speed reducer
which chain-drives the feed rolls and
coil support mandrel. A one-way clutch
allows the feed rolls and coil support
mandrel to “over-run” when the cold
former pulls the stock. Reversing the
direction of rotation is accomplished
by automatically “locking-out” the
over-running clutch whenever the
reverse button is pressed.
Uncoilers/Payoff
Equipment
Adjustable Speed (-02 Designation)
Adjustable speed models (-02) are usually employed on applications involving wire/rod consumption faster than
30 fpm (9 m/min). An AC variable
frequency drive controls the speed of
a TEFC motor. This motor drives the
speed reducer which chain-drives the
feed rolls the same as with a fixed
speed uncoiler. The advantage with
adjustable speed is that the entire coil
can be continuously rotated at a speed
approximately equal to the consumption rate. This not only alleviates
most of the load on the production
machine’s feed rolls, but assures that
the coil is in a “loose”, tangle-free
condition.
A calibrated potentiometer provides a
reference for the operator so that once he has determined the proper uncoiling speed for the job, he can reset the
speed for the same application in the
future.

Feed Rolls
All RMG Power-Driven Uncoilers are
equipped with a coil sensor. Whenever
the coil begins to cinch-up or bind:
V-grooved feed rolls are standard for
hot-rolled rod with a range of approximately .130” (3.5 mm). Full contoured
rolls are recommended for drawn wire.
Standard feed rolls are case hardened
thru-hardened rolls are available as part
of a “green rod” kit, which also includes
thru-hardened straightener, guide and
splitter rolls.
1.
2.
On -01 models, the coil support mandrel is power rotated.
On -02 models, the coil support mandrel is power rotated, and if the coil continues to cinch-up or tighten, the mandrel rpm is increased.
After the coil frees up, the mandrel will continue to run at the increased rpm for a brief period, determined by a timer setting. This is another setting that may be recorded for future reference.
3.
On both -01 and -02 models, a snag detector option is available so that if the coil continues to bind up, the sensor will send a signal to the pro
duction machine, thus stopping the process before a short feed occurs.
All RMG Power-Driven Uncoilers are
arranged for quick changing of the feed
rolls.
Pneumatic Equipment
Unique heavy duty actuators provide
power and dependability for the feed
rolls and straightener. All necessary filters are provided as standard equipment
and all valves are manifold mounted,
with visual indicators, plug-in solenoids
and mechanical overrides.

1. How much distance should we allow
between the uncoiler and the cold former (or wire drawer)?
When the feed roll height of the cold
former is the same as the uncoiler, only
three feet is required. For each inch
of difference in this height, add six
inches to the distance between the two
machines.
2. Can RMG provide higher feed roll

Yes. We accomplish this by altering the
basic dimensions of the machine frame.
We must always anticipate an O.D. coil
dimension of 50” (1270 mm), therefore
we would not consider lowering the feed
roll height.
3. Will RMG machines accommodate
6000 lb. coils?
Although the table on page 5.2 indicates
that the Model 2024 will accommodate
7000 lb. coils, the actual weight depends
on the physical size of the bundle. A
7000 lb. coil of 5/8” material may be too
large, whereas a 7000 lb. coil of 1-1/2”
material can easily be accommodated.
4. When should adjustable-speed drives
be used?
Generally speaking, whenever the uncoiling speed exceeds 30 fpm (9 m/min.),
and on most long-stroke applications
involving cut-off blank lengths of 8”
(203 mm) or longer. The adjustable-
-21
speed drive is always a good investment
because it can be set up to continuously
rotate the coil, helping to reduce the load
on the cold former’s feed rolls. This minimizes the possibility of short feeding, and
at the same time minimizes coil tangling.
5. Why not keep the feed rolls of the
uncoiler engaged all the time? Wouldn’t
this provide even greater assistance to
the cold former’s feed rolls?
In theory, this is a good idea. In practice,
it can’t work unless the uncoiler could be
moved back about 25 feet (7.6 m) to allow
a “storage loop” to make up for differences in feed roll timing, velocity characteristics of the cold former’s feed rolls, etc.
6. Should the uncoiler be anchored to the
floor?
Yes, four hold down holes are provided.
7. On a typical cold-former or boltmaker
application, why not keep the uncoiler’s
straightening rolls engaged at all times?
This isn’t advisable. In the first place,
these straightening rolls are not designed
for continuous straightening. In the second
place, the additional load imposed on the
cold former’s feed rolls—along with perhaps a 2000 lb. (907 kg), 3000 lb. (1361
kg) or 4000 lb. (1814 kg) coil—might do
more harm than good.
8. Can we use coils wound with a lefthand pitch interchangeably with those
wound with a right-hand pitch?
Almost all coils of hot-rolled rod and wire
produced in North America are wound
with a right-hand pitch, so that they
uncoil from left to right. It is impractical to attempt mixing-up LH and RH
pitch coils. While RMG machines may be
arranged to be field-changed to accommodate either LH or RH pitch coils, it means
the uncoiler must be pointed 180° in the
opposite direction and the location of the
straightening assembly changed.
9. We have quite an inventory of feed rolls
for our existing combination prefeeders
and uncoilers. Can we interchange RMG
feed rolls with our existing machines?
Yes, on all types except the Malmadie
(or W-F) type of prefeeders.
10. What range of rod and wire sizes will
the feed rolls accommodate?
When used for uncoiling wire, the feed
rolls must be machined exactly to the finished cold-drawn wire size. This prevents
deformation of the accurately-sized wire.
When used for uncoiling rod, the feed
rolls are machined with a V-grooved
configuration which accommodates a
range of approximately 1/8”/3.30 mm (±
1/16”/1.52 mm). Feed rolls for rod should
be selected using the chart shown above.

Z-Flippers
5.10
Recognized as the industry’s most rugged coil stand, the RMG Z-Flipper is
designed to accommodate two coils and
permits continuous pay-off of wire or
rod when used in conjunction with an
in-line wire drawing machine.
Operation
The active coil is pulled off while the
stand-by coil is loaded. While the production machine continues to produce
parts, the operator unbands the stand-by
coil and butt welds the head-end to the
tail- end of the active coil. When the
active coil is depleted, the operator turns
the flipper to bring the stand-by coil into
position while the production machine
continues to produce parts. No downtime is required for coil changeover.
Uncoilers/Payoff
Equipment
1.The combination of the lower
restrainer bar and the upper escape ment ramp allows only one loop to
exit at a time, minimizing the chance
of tangling. The lower escapement has an adjustable spring tension for fine tuning wire behavior.

accomodate creative floor plans.
2.Coil weight is not a limiting factor.
These units are designed to accommo-
date any coil providing its size, when
unbanded, does not exceed the CW
dimension.
3. Equipped with tapered roller anti friction bearings and a heavy-duty stop, the RMG flipper is regarded by
operators as the easiest to rotate and
position.
4.No special foundations required.
Standard anchor bolts are used.
5. Flippers are available with rectangu-
lar tubular arms for diameters over .375” (9.5 mm). Saddles are recom-
mended for smaller diameters.

Optional Accessories for RMG Turntables 5.12
Mechanical Brake
Wire Basket
Uncoilers/Payoff
Equipment
This is a solid steel ring welded to the
circumference of the turntable plate.
Unlike most advertised “snag rings”,
RMG’s basket construction is virtually
indestructable. The basket helps
prevent random loops dropping below
the turntable’s plate. On most applications, selecting the next larger top
plate represents a better way of preventing random loops from dropping
below the top plate. On high-speed
applications, a combination of a larger
top plate and an electrically-interlocked air brake is the best way of
preventing overcoasting and random
loops.
This is simply a manually adjustable
friction-type brake and is usually not
recommended because the constant drag
tends to cause the wire to cinch up.
RMG’s mechanical brake offer’s two
distinct advantages:
1.RMG’s brake construction prevents
damage to the brake mechanism.
2.The braking action is applied on the
bottom surface of the top plate near
the outboard edge. This provides
much better control of the braking
drag force.
Air Brake
Especially suitable for relatively highspeed applications in excess of 100 fpm
(30.5 m/m) or whenever the product of
the coil weight times the speed in fpm
exceeds 300,000. (For example, 2000
lbs x 150 fpm = 300,000). The air brake
permits the coil to rotate freely during
normal uncoiling. When the wire production machine stops, air is directed to
two equally balanced air cylinders (four
cylinders on heavy-duty turntables) for
controlled deceleration. Electro-pneumatic air valve not included with air
brake.

How the system works
Air adjustable tension dancer arm senses the demand of the production
machine under all operating conditions. This arm controls the operation of a
variable frequency drive controller which changes the speed of the top plate.
As the production machine decelerates and stops, the control arm automatically returns to the stop position. Using dynamic breaking the VF drive
reduces the coil rpm. When the control arm reaches the stop position D/C
injection braking is applied to bring the coil to a complete stop. This speed
control system enables the unit to match the consumption rate of the production equipment greatly reducing load on the feeding system.

RMG’s unique design, The Integrator®, provides users with the
following benefits:
1) The ability to control the wire’s straightness with a single-knob or
single-screw adjustment.
2) The ability to accommodate a very wide range of wire diameters by being able to mount many different rolls, on various center distances
on a single assembly.

Typical Model Designation
1.Single adjustment straightness con-
trol.
2.Wide range of wire or rod diameters.
A minimum range ratio of 4 to 1 can

3.Complete line from .030” to 1.75” (0.8 mm to 45 mm).
4.Modular construction. Most RMG Integrated Wire
Straighteners can be changed in the customer’s plant from left-to-
right or right-to-left wire flow, and for either horizontal or vertical uncoil-
ing. Complete assemblies can be fur-
nished using a different number of rolls in each plane.
5.Many unique construction features, including universal X-Y-Z axis adjustment, sealed double-row ball bearing construction, and carbide entrance guide bushings.

Model SS and MS Straighteners
The most universal assemblies for easy
conversion from one diameter range to
another. One has only to unscrew one
set of rolls and screw in another set to
convert it from one diameter range to
another. All Model SS and MS mounting frames include pre-tapped holes for
roll changing at any time in the future.
Model LS, KS and JS Straighteners
These models are converted from one
range to another by replacing entire
sub-assemblies referred to as “rails,” on
which the individual rolls are mounted.
The bending loads imposed on the
shafts by relatively larger wire and rod
diameters preclude the use of screw-in
mounts.

mounting shafts or studs. This includes
any type of straightener on which a
centralized grease lubrication system is
specified.

Power-Driven Feed Rolls
Power-driven feed roll assemblies can be ordered for all Model LS and larger straightener assemblies. These are usually
powered by a 5 HP adjustable speed drive, but many optional drive arrangements are available with custom-designed transmission assemblies.
Power-Driven Uncoiler Combinations
RMG’s power-driven uncoilers are used for rod and wire diameters in a range of .625” - 1.75” (16 - 45 mm). Type KS and
larger straightener assemblies can be easily adapted to these power-driven uncoilers.
Roll-type straighteners, including RMG’s Integrator, do not achieve
perfect straightness. Only a rotary arbor type straightener can consis-
tently provide this straightness qual-
ity.
3. Optimum L/d values are usually in a range of 6 to 10 for mild steel. Harder or tougher materials favor a higher value; softer, non-ferrous materials favor lower values.

4. Optimum L/d values are in a range of 6 to 10. The advantages involved in being able to change (1) the number of rolls, (2) the roll center distance and (3) the roll diameter (with a required change in wire diameter) should be obvious.
5. Two-plane straighteners can be

RMG Integrated
Multi-Roll Wire
Straighteners
General Specifications
Almost all roll-type wire straighteners
use the reverse-bending technique illustrated below.
The object is to cause the wire to reversibly flex beyond its elastic limit as it
traverses through the straightening rolls.
Most straighteners in use today provide
a screw adjustment on each individual
roll and the operator individually adjusts
each roll to achieve the desired straightness.
The usual set-up procedure is to adjust
the rolls so that a greater degree of offset or reverse-bending is imposed on the
upstream rolls at positions 1-2-3. The
downstream rolls (5-6-7) are adjusted
so that gradually less reverse-bending
is imposed upon the wire as it traverses
through the straightener. The final set of
rolls should impose just enough reversebending to flex the wire just very
slightly beyond its elastic limit and hope
that it “springs back” to a reasonably
straight condition.
How The Integrator works
The Integrator
6.3
straightener and usually requires readjustment only when the wire diameter
is changed.
The force required for reverse-bending
the wire is imposed by the quick-release
handle working against the upper plate
assembly. The upper plate is slotted and
secured in place by two socket head cap
screws. Re-tightening of the cap screws
after each opening and closing of the
straightener is usually necessary only on
intermittent-feed applications.
Easy Conversion to Two Planes
Complete adjustments are provided
for wire-line alignment in both axis.
Standardized mounting holes are provided to permit field conversion from
left-to-right or right-to-left with the
horizontal plane mounted either right or
left.
The quick-release handle is screwed
downwards, tilting the upper movable
plate assembly until it bottoms out
against the setting of the thumb screw.
This thumb screw is adjusted up or
down so that the wire exiting from the
straightener has been subjected to minimum reverse bending at rolls 5-6-7 just
enough to attain desired straightness.
Essentially, all rolls are positioned relative to each other, and in a controlled,
integrated manner with this single position-limiting thumb screw.
Optional Accessories
The Integrator’s Unique Features
3.Entrance roller guides and end-of-coil
detection switches.
“Three-in-One” Construction
Two basic-size straighteners each
accommodate three different sets of
rolls on different center distances.
Therefore, RMG can offer six different
models in two basic sizes. To change
the straightener over to a different wire
diameter range, simply unscrew one set
of rolls and replace with another set.
We provide a number of standard
optional accessories and mounting
arrangements with RMG integrated wire
and rod straighteners:
1.Heavy-duty frames for mounting
Model SS and larger straighteners.
These are typically supplied when
ever RMG power-driven feed rolls are required.
2. Fixed-speed or adjustable-speed drives for power-driven feed rolls.
4. Straightener benches are available to
support all sizes.
All lower rolls are attached to the fixed
lower plate along a straight line. The
upper set of rolls are attached to a tiltable upper plate which pivots about a
set screw. This pivot-point set screw
determines the degree of relativelyhigher reverse-bending imposed upon
the wire on the entering end of the
Saves operator time and effort and
achieves optimum wire straightness
with minimum pull-back being imposed
upon the wire. Straightness-setting
thumb screw is changeable from left
side to right side, permitting either leftto-right or right-to-left wire flow.
Quick-Release with Memory Return
Whenever the quick-release handle is
disengaged and re-engaged, it always
returns the upper roll assembly to the
predetermined position.

RMG Model JS-1607-00 Straightener
Special HS and GS
Straighteners
These two large series of integrated
wire and rod straighteners are available in only two model arrangements:
Model HS-3005 for wire and rod
diameters in a range of .700”
(17.8 mm) to 1.30” (33.0 mm)
Model GS-4005 for handling wire and
Multi-Roll
Straighteners
rod diameters in a range of 1.00” (25.4
mm) to 1.75” (44.5 mm).
Because of the extreme difficulty in
handling, pre-straightening and
pre-feeding, an RMG Power Driven
Uncoiler is almost always recommended for use with these larger straighteners.

RMG Overhung
Load Adapters
Rockford Manufacturing Group offers quality overhung load adapters in
standard, SAE A, SAE B, SAE C, SAE D and custom designed to meet your
exact application requirements.
SAE and DIN Overhung Load
Adapters
Furnished with pre-heat-treated
4140 shafting, these input shaft
assemblies are primarily intended
to:
•
Permit easy adaptation of
standard electric motors to gear
reducers and clutches which
normally interface only with
hydraulic motors.
7.1
SAE A type adapter.
SAE B type adapter.
SAE C type adapter.
SAE D type adapter.
• Permit the adaptation of belts
and pulleys (instead of direct
“plug in” hydraulic motors).
•
Permit the adaptation of belts
and pulleys coupling an electric
motor to gear reducers for use
with Variable Frequency Drives.
The use of belts and pulleys
(on either hydraulic motors or
electric motors) with gear reducers,
torque Hubs or clutches can often
solve space problems. Additionally,
by being able to belt drive the
transmission equipment, it is
possible to enjoy a wider selection
of reduction ratios, speed values,
and service factors.
