Loading Film

The 640t laminator runs poly-in and

poly-out pressure sensitive adhesive (PSA) films. Poly-in means the adhesive side of the film is on the inside of the film roll. Poly-out means the adhesive is on the outside of the film roll.

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 film must be the same width.

Always change the top and bottom supply rolls at the same time.

The film 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 film.

•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 film, the print clamp and feed table need to be removed.
