The machine can perform four functions:
Decaling (laminating and applying an adhesive •
to the back of the item).
Mounting, using one film.•
Mounting, using no film.•
Roll-to-roll over-lamination.•
IMPORTANT: The top and bottom rolls of laminating
lm must be the same width.
Always change the top and bottom supply rolls at the
same time.
The lm will wrap around the rollers if:
One or both rolls of film are allowed to run •
completely off its core.
Only one roll is used.•
Different widths of rolls are loaded together. •
Either roll is loaded with the adhesive side •
against a roller.
There are two methods of loading lm.
Using a threading card.•
Tacking new film to existing film.•
These are described in “Threading Film with a
Threading Card” on page 6-5 and “Loading Film by
Tacking New Film to Existing Film” on page 6-7. Prior
to loading lm, the print clamp and feed table need
to be removed.
