GEM TYPE AMO-B OFFSET PRINTER
Instruction Sheets
The Gem Type AMO-B Offset Printer transmits a printed
legend to insulated cables by contact with a rubber faced
print transfer roll.
The inked legend is transferred to this rubber roll by contact with a flat faced engraved steel print wheel which
revolves in a bath of ink. The excess of ink is wiped off
the print wheel face by a flat poly wiper material.
Both the engraved steel print wheel and rubber face ink
transfer roll are driven by cable contact.
The Gem Type AMO-B Printer has been designed to mark
wire, cable or pipe up to 3-inches in diameter at operational speeds.
The machine accommodates standard marking wheels
which utilize flat surface photo-engraved for striping,
numbering or lettering.
As delivered, the machine is set up and ready for use with
the marking wheels ordered.
For high-speed drying and clean, sharp impressions, it is
essential that Gem inks be used. Gem formulates and
processes a full line of inks for marking wire and cable
for all insulations.
Properly maintained and cleaned, the Gem Type AMO-B
Marker can be expected to provide years of dependable
service.
Locate the marking machine between two water troughs
in the extruding line. The first trough should be of
relatively short length (CF. Note 1). Also, it should be
equipped with a portable sponge weir (or dam) and
should have one or more air-wipes at the outgoing end.
The second trough should be of standard length.
Note 1: The length of water in the first trough should be
shortened by use of sponge dam to the point where, as
the hot insulated wire emerges from the cooling water,
the surface of the wire is covered with beads of water.
Under this condition the air wipers drive off the remaining water from the surface most effectively.
Adjust the height of the machine so that the wire-run
passes between the transfer roll and the lower guide
wheel. Under operating tension the wire should just clear
the transfer roll. It should be necessary to crank down the
guide wheel, applying a slight pressure, in order to bring
the wire in contact with the printing surface of the
transfer roll.
Center the marker so that the wire is directly over the inked legend on the transfer roll. Once the guide wheel is
lowered to apply pressure on the wire, slight centering
adjustments can be made by loosening the shaft-housing
lock screws on the back of the machine and sliding either
the top or middle shafts in or out.
Set up
1. Using the two top hand wheels, crank the top and middle wheel shafts apart.
On the top wheel shaft, mount the appropriate cable
guide roll (See listing).
On the middle wheel shaft, mount the rubber faced ink
transfer roll.
On the bottom wheel shaft, mount the flat faced
engraved steel print wheel.
2. Insert fresh flat poly wipe (1-1/2” x 1/2” x 1/8”) into the
slot of the brass wiper holder.
Mount wiper holder on the holder pin and position
slide plate so that the wiper fingers fits around the
print wheel, and the bottom sharp edge of the poly
wipe contacts the wheel face on an angle, approximately 15”.
Engage the coil tension spring on to the split ring
fastened to the bottom of the wiper holder.
Crank and adjust the wiper tension assembly to provide a small amount of drag on the print wheel face
when it is rotated by hand.

3. Proper wiping is essential, since the insulated wire
must be clean and dry for good printing. It is not
necessary to exert considerable tension on the wiper.
If positioning is correct, and if the wiper edge is sharp
and clean, wiping will be accomplished easily and
with minimum tension.
Excessive wiping tensions wear out wipers quickly.
Further, the added top pressure required to make the
wire overcome the added drag on the marking wheel
causes splayed or blurred printing and shortens the
life of the etched printing surface.
Fill the inkwell only to a point where the ink covers approximately 1/2” of the bottom of the marking wheel.
This is sufficient to provide a puddle of ink under the
wiping edge of the wiper holder. Excessive filling will
result in ink being splashed over the wire and the
equipment.
Ink cans should be thoroughly shaken before use each
day. When not in use, cans should be capped.
Ink viscosities vary according to application but, for
most purposes, the ink should approximate the consistency of light coffee cream.
4. Check whether wiper tension adjustment is proper to
wipe the face of the print wheels clean. Once this is
determined, using the rear top crank, position the rubber face ink transfer roll so that it just contacts the
print wheel, and so that a clear print is transferred to
the rubber roll.
5. Finally, center the cable to be marked between the top
cable guide roll and the rubber face ink transfer roll
that is now carrying the inked print legend.
Using the front top handwheel, bring the cable guide
roll down forcing the cable to slightly contact the rubber face ink transfer roll.
Start the cable line slowly and check the print appearance on the cable after it passes through the
marker. (It may be necessary to make small adjustments to the wheel contacts, guide contact, and wiper
tension adjustment to obtain best results.)
Once the print is satisfactory, bring up the cable line
speed.
GEM TYPE AMO-B
OFFSET PRINTER
Suitable for Continuos Operations
or Short Lengths
To Change Print Wheel
1. Release contact of top cable guide to cable.
2. Release contact of rubber face ink transfer roll to print
wheel.
3. Remove inkwell and position under print wheel to
allow ink to drip back into inkwell.
4. Loosen wiper tension and remove wiper holder and
clean.
5. Remove print wheel and clean.
6. Using cleaner solvent, clean face or rubber transfer
roll.
7. Mount new print wheel and wiper holder inkwell and
reposition rubber face ink transfer roll to contact print
wheel as described before.
8. Follow steps given in Set up instruction.
THE GEM TYPE AMO-B OFFSET PRINTER transmits a
perfectly defined legend or code to hardened or irregular
contoured products through contact with a rubber-faced
transfer roll in conjunction with its exclusive ROTOGRAVURED steel print wheel as it revolves through a
bath of liquid ink. This gives the capability of rapid code
and color changes. ROTOGRAVURED print wheels can
be specifically ordered for all types of legends, codes,
and logos and fast drying liquid inks are available in all
colors of all types of products.
THE GEM TYPE AMO-B OFFEST PRINTER is rugged,
compact, and simple to operate and maintain.
Maintenance
1. At end of each days run, clean the print wheel, rubber
face roll, wiper holder, etc.
2. Before starting up on new run - shake ink can
thoroughly, then check ink viscosity to see if it is
similar to that when fist received. (It may be
necessary at times to add a slight amount of thinner
to the ink to achieve the desired viscosity).
Reposition or replace flat poly wipe in the wiper holder
so that a clean, sharp wipe edge will contact the print
wheel when in position.

PROCEDURE TO REVERSE
MARKER DIRECTION
1. Remove wiper holder.
2. Remove slide plate assembly to opposite side of machine. Make sure that
the wiper support pin is in the same relative position in order to keep the
proper angle between the wiper holder and the marking wheel.
3. Remove the two 10-32 x 3/8 flathead screws that fasten the wiper tension
assembly to the base casting. Turn the wiper tension assembly around,
reversing position. Insert screws and fasten to the opposite side of the
base casting.
4. Replace wiper holder on the side with the re-positioned slide plate and
wiper tension assemblies.
5. Change all shaft direction. It is necessary to provide the proper thread
direction to keep roll nuts from loosening when marker is running.
6. If machine is equipped with a solvent dripper, remove and install on the
opposite side.
The marker is now ready to operate in the reverse direction.
