Loading Laminating Film - usi CRL 40 Instruction Manual

7. LOADING LAMFILM
The first steps in this process are to remove the remnants of the old roll of film (See Section 9.9, Page 18)
and if necessary, to clean the nip rollers (See Section 10.1, Page 22). Also see page 8a for USI colour code.
(Note: Stickers already on the machine)
7.1 The laminating film has a dull side and a shiny side. The dull side is the adhesive and extreme care
must be taken not to lay this side against the heat shoes or a lengthy cleaning process will be
required.
7.2 When loading laminating film with dull side out. Film should come off the top of the roll.
7.3 Check your roll of film for the occasional splice. While unusual they are unavoidable and if you
find one, place that roll on the top position (see Section 12.2, Page 24). Slide your roll of film onto
the supply mandrel. As it is rotated, the roll should lock. The film position on the top mandrel
should unroll from top towards the operator. The film on the bottom mandrel should unroll from
top away from the operator.
7.4 Remove the feed table to facilitate film loading.
7.5 Release the tension control on top and bottom mandrels so as the film unwinds freely. Position the
mandrels loaded with film in the mandrel supports.
7.6 Pull the film from the top mandrel and thread it under the top idler bar, draping the web over the
front of the top heater bar. It is a good habit to fold back 25 mm (1 inch) of the film onto itself
(adhesive to adhesive) at this point, to ensure the film does not curl back towards the heat and touch
or stick to the heat shoe. (See Fig 7.1).
CAUTION :
An excessive fold-back of more than 50 mm (2 inches) could foul during threading.
