Setup of the ORCA-I Laminator is quick and
straightforward when instructions are followed
exactly.
CAUTION
Always use the same shim settings on the left
and right side of the laminator.
To adjust the nip please see Section 4: Maintenance
and Troubleshooting.

Use only the minimum amount of roll pressure
needed to accomplish the task. While higher pressure
can make the adhesive bond faster, excess pressure
can damage the rolls. Wrinkles and bubbles have
causes that generally cannot be cured by applying
more pressure.
CAUTION
Excess pressure can damage the laminating
rolls. Minimum laminator roll pressure is
consistent with good results.
A typical roll pressure for soft substrates such as
Foamcore is between 20 to 30 pounds per square inch
(PSI) or 140 to 205 kPa.
The range of typical values for hard substrates is 25
to 50 PSI or 170 to 345 kPa.

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 the bottom unwinds. There are
two important 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 will immediately bond to the roll,
creating 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
Always mount the film so that the adhesive
side faces outward from the laminating roll.
This prevents hours of roll cleaning.
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 assorted troubles
will occur.
⇒
NOTE
55” wide material must be slightly off-center for it
to clear the unwind brake mounting brackets.
CAUTION
Carefully align the two films being fed into the
nip. If not, you will obtain poor results.

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.
