Operation
4-6
Pressure Sensitive Process
1. Load film on the rear upper unwind station. Loosen the brake tension by turning counter knob
counter clockwise.
2. Set the shim wheels to “0”, or to the correct shim height if a board is being used. Place a piece of
feeder stock into the nip rolls with plenty of stock hanging out the front, and close the nip rolls
onto the piece of feeder stock.
The nip section can pull you into laminator! Do not place fingers
into the nip section when the rolls are rotating. It is
recommended that operators tie long hair back and not wear
neckties, loose clothing and jewelry since they can be caught in the nip section and pull the
operator into the machine
3. Pull the film from the upper rear station down under the idler roller directly behind the nip roll and
over the top of the top nip roll. Separate the release liner from the film and tape the film to the
feeder stock.
4. Route the release liner in an “S” wrap on the idler rolls and back to the upper front windup station.
Tape the release liner to the wind up core.
5. Set the speed potentiometer to a low setting, select Fwd with the selector switch. Jog the
machine forward to run out film. Be sure to place scrap substrate between the film and the lower
nip roll to avoid adhesion to the lower roll.
6. Move to rear of machine and guide film up over the pull roll guard.
7. Turn the heater control to “On” and set the desired temperature.(if required) While the roll is
heating up, use your process control chart to make all initial settings on the brakes, speed and nip
pressure.
8. With roll at the desired temperature you may feed the substrate into the nip section.
