Tension - usi 1800-2700 Owner's Manual

TENSION

To adjust tension for upper and lower rollers, the laminator must be loaded and heated.
Remove the heat guard and feed tray. Loosen both tension control knobs by turning counterclockwise until there is no
tension on upper or lower film rolls. Photos 13-1, 13-2.
Film should pull freely.
Turn the drive switch "On" and set to a slow speed
As film runs through it will appear wrinkled and bubbly, as pictured in photo 13-3.
Gradually increase tension on both rolls, by turning knobs clockwise, until film is smooth
on heat shoes. Once film is smooth, stop tightening knobs.
NOTE: For best results, reset tension with EACH new pair of film rolls.
NOTE: As the film roll supply becomes low it is necessary to decrease tension on the rolls.
NOTE: Too little tension on the top or bottom roll causes vertical or diagonal streaks in the
film as it passes over the heating shoe.
WARNING: Excessive tension will lead to increased wear and tear on the laminator.
Once the laminator is loaded, heated, tension adjusted—install the Feed Tray and Heat Guard, as shown below in
Photos 13-4 and 13-5.
