Film is loaded on the appropriate unwinds. Loading
and aligning the film are discussed later in this section.
For applications such as encapsulation, film is fed from
both the top and bottom feed unwinds.
The process of loading and aligning film is the same for
both the top and bottom unwinds. There are two impor-
tant points to remember when loading film:
1. The adhesive side of the film must be oriented
away (on the outside) from the laminating roll.
Otherwise it immediately bonds to the roll, creat-
ing a major clean-up project.
Films have a shiny side and a dull side. The dull
side is the one with the adhesive. The dull side
should ALWAYS face outward from the laminating
roll.
CAUTION
2. The film must be centered on the unwind for best
performance. This is vital when two films are fed
together. If the two films are not aligned, feed
problems, wrinkles and other problems occur.

NOTE
55” wide material must be slightly off-center for it to
clear the unwind brake mounting brackets.

The following procedure is applicable to both the top
and bottom feed unwinds.
1. Open the top unwind by removing the pin and
swinging the arm out.
2. Load the film.
3. Return the arm to its locked position and reinsert
the locking pin.
4. Center the film on the unwind arm by measuring
the distance from the ends of the film to the sides
of the machine using a tape measure.

Use the following instructions when heating one or
both of the laminating rolls. The procedure is the same
for the top and bottom heaters.
1. Set the heater switch to ON. Both controllers must
be on for either roll to heat. To heat only one roll,
adjust the set point for the other roll to a value that
does not call for heat (e.g. 32).
2. Adjust the temperature controller for the desired
operating temperature using the temperature con-
troller push buttons.
3. When heating the rolls, keep the top roll down and
turning at a moderate speed to prevent uneven heat-
ing.
It takes approximately 30 minutes for the laminating
roll(s) to reach operating temperature. When the preset
operating temperature has been reached, the machine is
ready to use.
The ORCA-I SP can be used for cold mounting while
maintaining the temperature of the main laminating
rolls by using the pull rolls as a laminator (by feeding
prints from the rear) for a quick change-over between
hot and cold laminating.
Always mount the film so that the adhesive side
faces outward from the laminating roll. This
prevents hours of roll cleaning.
Carefully align the two films being fed into the
nip. Misaligned films can result in poor quality.
