The following procedure uses a film threading card
that is sometimes provided with new rolls of film. If
one is not provided, a scrap piece of cardboard or
poster board with a straight edge is suitable. Either
can be reused. Prior to loading film, remove the
safety shield and feed table.
Note: These instructions are for loading laminating
and mounting films for decaling. The top supply
shaft is used for laminating films and the bottom
supply shaft is used for mounting film or kraft paper.
If you are not applying mounting film to a laminate,
kraft paper should be used on the bottom supply
shaft to prevent adhesive from sticking to the rollers.
For more information about loading films for other
processes, refer to the appropriate section in this
chapter.
To web (load the films) the machine:
Remove the safety shield and feed tray. Refer
to
Safety Shield Removal and Installation and Feed
Table Removal and Installation in this section.
Pull the top film down, thread it under the idler
bar, and pull the film back up to the take-up core.
Lightly tape both corners of the film to the take-
up core.
Ensure that the film is pulled evenly and that no
bulges exist at either end of the idler bar.
Using a very sharp utility knife, lightly score the
laminating film approximately 4 in (10 cm) above
the upper pressure roller.
Be careful to not cut through the release liner.
Pull the laminating film away from the liner and
drape it over the front of the pressure rollers so
that it extends to a little past the bottom of the
top pressure roller.

Pull the mounting film (or kraft paper) up to
about even with the top of the top pressure roller
without touching the sticky laminating film.
While pulling evenly, carefully align the edges of
the mounting film with the laminating film, and
press the two together. It is important that the
tension is even from one end of the supply rolls
to the other.

Press the straight edge of the threading card into
the two films at the nip (the point between the
two pressure rollers) until the card and films are
slightly past the nip.
