Operation Instructions for Release Liner Rewind (optional)
This laminator is equipped with the features necessary to allow the use of pressure sensitive film with
release for single side lamination. The release liner rewind will remove the release liner from the film
and wind the waste onto an empty core, which can then be disposed.
The pressure sensitive film should be mounted on the upper supply roll and threaded under the idler
shaft. An empty film core should be mounted on the waste rewind mandrel with the mandrel mounted
onto the laminator. A section of scrap media that is at least as wide as the film in use, should be
inserted into the front rollers of the laminator. Separate about 6 inches of the release liner from the
film and mount the exposed portion of the film to the media that has been inserted into the machine.
Bring the end of the release liner under and up, to the waste rewind mandrel. Then, tape the release
liner to the spare core that has been installed to the mandrel. The waste rewind mandrel may be
rotated by hand to assist in the start up. Slowly advance the motor of the laminator. While guiding the
film and the media to the rear rollers, insure that the release liner is firmly attached to the waste
rewind core.
The separation point for the film and the release liner should be between the idler shaft and the point
where the film contacts the heat shoe. The separation point can be adjusted by the tension knob on
the waste rewind drive shaft. If the separation point is past the point were the film contacts the heat
shoe, tighten the tension knob slowly until the separation point moves towards the idler shaft. If the
separation point approaches the waste rewind mandrel or the idler shaft, loosen the tension knob
slowly until the separation moves towards the heat shoe. The tension setting should need very little
adjustment once set, but should be monitored during operation.
Once the separation point is set, lamination is performed normally. Care should be taken to minimize
the gap between successive pieces of media being laminated so that the adhesive from the film is in
contact with the lower roll as little as possible.
Tension
To adjust the tension for the upper and lower film rolls, the laminator must be loaded and
heated.
Remove the feed tray. Loosen both tension control knobs by turning counterclockwise until there is no
tension on the upper or lower film roll. Film should pull freely.
Turn the drive switch “ON.”
As the film runs through, it will appear wrinkled and bubbly. Gradually increase the tension on both
rolls by turning the knobs clockwise until the film is smooth. Once the film is smooth, stop tightening
the knobs.
NOTE: For best results, reset the tension with EACH new pair of film rolls.
NOTE: As the film roll supply becomes low, it is necessary to decrease the tension on the rolls. Reset
at approximately the last 1/3 to 1/4 of a roll.
NOTE: Too little tension on the top or bottom roll can cause vertical or diagonal streaks in the film as
it passes around the heated rollers.
NOTE: When using thicker films, wrinkling and bubbling may occur if the laminator’s speed is set too
fast.
WARNING: Excessive tension will lead to increased wear and tear on the laminator. Once the
laminator is loaded, heated and the tension adjusted – reinstall the feed tray.
