16. DOUBLE SIDE LAMINATION ONLY: Adjustment
of tension controllers:
There are four (4) tension controllers. Two for the
lower film roll and two for the upper film roll. The
purpose of the tension controllers is to apply
resistance or "drag" on the film rolls which makes
the film lay flat on the heat chambers and thereby
eliminates creases and bubbles in the lamination.
It is recommended that the right side and left side
controllers on each roll be adjusted with the same
amount of tension. The top pair of controllers
versus the bottom pair of controllers may vary
slightly only to eliminate "curl" in the
laminated piece. If the laminated piece curls
upward loosen the two upper controllers or tighten the two bottom controllers. If the exiting laminated
piece curls downward, do the opposite and make the lower controllers looser than the upper
controllers.
NOTE: Single sided lamination: Do not apply any tension to the upper or lower controllers. Leave all 4
thumbscrews loose.
17. When the laminator has "warmed-
up" and the READY light is on, use the
manual MOVE switch to run samples of
film out of the laminator. Observe these
samples for clarity and freedom from
wrinkles. When all of the bubbles,
wrinkles and creases disappear from the
lamination and the film is laying flat on
the heat shoes the machine is ready to
be run in “automatic mode”. If these
lamination defects are not disappearing
in a reasonable amount of film footage
(3 or 4 feet), slightly increase tension on the controllers (equally). See Step 18.
18. Test for film curl. This is important. If film will not exit the machine in “manual mode” in a “flat” state
there may be jams and wraparounds occurring when the machine is run in “automatic mode”.
If not already done, push the manual MOVE switch forward until about one (1) foot of film has exited
the laminator. Then, using a pair of scissors cut the laminated film at a point approximately one (1) inch
out from the laminator. Be sure to identify the upper side of the film from the lower side of the film.
