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 upper idler roller and over the top of the
top nip roll. Tape the film to the feeder stock.
4. Lower the infeed table by pulling the handle located under the center of the table. Rotate the
table down. Pull the film from the center front station up between the nip roll and the idler roller.
Tape the film to the feeder stock.
5. Rotate the table back into place until it locks.
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 rolls with the switch located to your left 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.
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 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.
