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.
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.

manifold mounted for easy
maintenance.
12. Integrated straightener for prestraightening the wire located on the
side of the feedhead. Includes simple, one-stop straightening adjust
ment.
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 rotation.
• 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
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.

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. On -01 models, the coil support
mandrel is power rotated.
2. 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
heights?
UNCOILERS/PAYOFF
EQUIPMENT
1-1/2”
38 mm
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.

DL 3300 Prefeeder
5.9
The RMG DL3300 Prefeeder is especially suited for high-speed bull blocks,
as coil changeover and pointing time
can be minimized. At the same time, the
system enables use of the relative tangle-free attributes of turntable uncoiling.
Benefits
1. Used in set-up of large diameter
(5/8”/15.9 mm to 1”/25.4 mm)
material when consumption rates
exceed the rating of a powerdriven uncoiler.
2. A commonly purchased option is a
chain pulling attachment to pull the
end of the coil over to the feedhead.

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.

EQUIPMENT
Features and Benefits
1. The combination of the lower
restrainer bar and the upper escapement 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 accommodate any coil providing its size, when
unbanded, does not exceed the CW
dimension.
3. Equipped with tapered roller antifriction 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 rectangular tubular arms for diameters over
.375” (9.5 mm). Saddles are recommended for smaller diameters.

RMG turntables are offered in two different styles:
Standard-Duty and Heavy-Duty.
RMG Turntables
for
Wire and Rod

Standard-Duty Turntables
Typical coil weight capacities up to
4000 lbs. (1814 kg), standard plate
diameters of 30” (762 mm), 40” (1016
mm) and 50” (1270 mm), and with
many optional arrangements.
Heavy-Duty Turntables
Heavy-Duty turntables should be used
whenever the use of very heavy coil
weights (in excess of 4000 lbs./1814 kg)
is anticipated, or there is a requirement
for 60” (1524 mm) or 70” (1778 mm)
plates, or whenever loose coil loading is
required.
RMG turntables are equipped with the
industry’s most rugged spindle and
bearing assembly, with an exclusive
gusseted design which resists damage.
The bearing assembly is accessible from
above the top plate for inspection, servicing and adjustment without removing
the top plate.
Tubular Coil Loading Systems
Turntables for tubular carriers (high
hats) represent one of the most practical methods for paying-off wire and rod
into wire drawing machines or directly
into the cold header or other wire production machine.

Coils of wire or rod in the 2000-4000
lb. (907-1814 kg) range can be accommodated due to the turntable’s very
high weight capacity and low center

significant improvement in operating
efficiency.

package is set on the turntable and the
wire or rod pays-off with a greater measure of safety and with less possibility
of tangling.

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.

Solenoid Valve for Air Brake
This is a three-way solenoid valve used
to direct air pressure to the turntable’s
air brake whenever the production
machine stops. Air pressure is automatically relieved from the air brake whenever the production machine starts.
RMG Variable Frequency
Drive Power-Assisted
Turntables
RMG power-assisted turntables have been designed to augment
the RMG standard free wheeling turntables, which have been regarded
as the standard of the industry.
At RMG, we’ve designed these turntables
to be responsive to higher production
speeds and larger coil weights, as well
as to meet the demands for a simple,
effective, easy to service turntable that is
responsive to all operating conditions.

Variable Frequency Drive Power-Assisted Turntable
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.

while minimizing snags and tangles in
the wire.
Our compact and robust design isolates
the weight of the coil from the lead wrap
of wire feeding into the straighten & cut
machine. This allows for reduced feed roll
pressure and improved cut length accuracy
while increasing production speeds.
