Encapsulation Process
1. Load thermal film on the upper rear and center front unwind stations. Loosen the brake tension
by rotating the knob counter clockwise.
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. Tape the film to the feeder stock.
4. Remove the infeed table for easier access to the front center station. Pull the film from the center
front station up over the idler roller directly behind the bottom nip roll and under the bottom nip
roll. Tape the film to the feeder stock.
5. Replace the infeed table.
6. Set the speed potentiometer to a low setting, select Fwd and press Run. Move to the rear of the
machine.
7. Open the pull roll guard until it latches, open the pull rolls using the handle on your right hand
side. Guide the stock coming from the nip rolls over the center idler and down through the pull
rolls. Close the pull rolls after the film has passed through the rolls. Close the pull roll guard.
8. To wind up the product, route the film down to the lower rear windup and tape to the core.
9. 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.
10. With rolls at the desired temperature you may feed the substrate into the nip section.
11. If your substrate is in roll form, you may use the lower 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
3 shows the front lower station being used as the unwind and the lower rear being used as the
product windup. Follow the procedure to load the film as discussed in the
Loading Film
section.
