Pressure Sensitive Process
1. Load film on the rear upper unwind station. Turn the selector switch to that station to “Off”.
2. Set the shim wheels to “0”, place a piece of feeder stock into the nip rolls with plenty of stock
hanging out the front. 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 front upper windup station.
Tape the release liner to the wind up core.
5. Set the speed potentiometer to a low setting an move to the rear of the machine.
6. Set the machine to run in the FWD direction (the FWD/REV button should not be lit) and press
the foot switch.
7. Guide the feeder stock into the gap between the pull rolls
8. Turn the heater controls to “On” and set the desired temperature. While the rolls are heating up
use your process control chart to make all initial settings on the brakes, speed and nip pressure.
9. With rolls at the desired temperature you may feed the substrate into the nip section.
10. If your substrate is in roll form, you may use the center front unwind station to feed it into the nip.
Route the substrate from the unwind station around the infeed table roller and into the nip. Figure
5 shows the lower rear station being used as the product windup. Follow the procedure to load
the film as discussed in the
Loading Film
section.
