Heating; Process Control Charts - GBC Laminator Operation And Maintenance Manual

Operation
The following procedure is applicable to both the top
and bottom feed unwinds.
1. Open the top unwind by removing the pin and
swinging the arm out.
2. Load the film.
3. Return the arm to its locked position and reinsert
the locking pin.
4. Center the film on the unwind arm by measuring
the distance from the ends of the film to the sides
of the machine using a tape measure.
Use the following instructions when heating one or
both of the laminating rolls. The procedure is the same
for the top and bottom heaters.
1. Set the heater switch to ON.
2. Adjust the temperature controller for the desired
operating temperature using the temperature con-
troller push buttons.
3. When heating the rolls, keep the top roll down and
turning at a moderate speed to prevent uneven

heating.

4. It will take approximately 30 minutes for the lami-
nating roll(s) to reach operating temperature. When
the preset operating temperature has been reached,
the machine is ready to use.
The F-60 Laminator has an adjustable clutch for the
pull rolls on the machine, allowing you to adjust the
amount that the film is tensioned as it leaves the main
rolls and is cooled. The clutch adjustment is made by
using the knob on the left side of the machine.
Pull roll clutch tension adjustment:
Turning the knob clockwise increases tension.
Turning the knob counterclockwise decreases tension.

F-60 Operation and Maintenance Manual
The pull rolls on the F-60 Laminator are preset for opti-
mum roll pressure and requires no nip adjustment. The
pull rolls can be raised for a
easy webbing of the machine.
Prior to raising or lowering the pull rolls, the pull roll
cover must be raised and locked into place.
The pull roll lever is located next to the pull rolls. To
lower the pull rolls, lift the lever up and rotate the lever
until it rests on the center table. To raise the pull rolls,
rotate the lever back down until it locks into place.
To proceed with operation of the machine, the pull roll
cover must be lowered.
When the machine is not in use, the pull rolls
must be raised to prevent damaging the rolls.
Always feed prints perpendicular to the laminating
rolls.
1. Lock core support to middle of the shaft. Lock two
core chucks on shaft ends, located to support mate-
rial a few inches from ends of the roll.
Note
Paper unwind may require two evenly spaced core sup-
ports if wide rolls of prints (paper) are used.
2. Place the roll on the unwind shaft.
3. Carefully close the unwind shaft, holding the roll
away from the hinge.
4. When the shaft is in the saddle, push in the locking
pin.
5. Center the roll of material.
6. Web and tension film per process control chart and
diagram.
