Setup of the F-60 Laminator is quick and straightfor-
ward when instructions are followed exactly.
To adjust the nip, please see Maintenance.
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 gener-
ally cannot be cured by applying more pressure.
CAUTION
A typical roll pressure for soft substrates such as Foam-
core 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.
With the guard removed, move webs through the main
roll nip by:
1. Pressing the RUN button for a slow, constant main
roll rotation.
or
2. Pressing the STOP button, then pressing the foot-
switch to set the required speed. Releasing the
footswitch stops main roll rotation.
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, cre-
ating 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 laminat-
ing 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 assorted troubles will
occur.
CAUTION
The F-60 laminator is capable of processing a wide
range of pressure sensitive and thermal laminates onto
an equally wide range of image materials. The primary
considerations are:
Laminate adhesives are compatible with image
materials.
The materials properly activate below the 270
°
maximum roll temperature and within the speed and roll
nip pressure ranges available on the laminator.
It is the operator’s responsibility to ensure the compati-
bility and operational settings for any laminates/image
material combination. GBC Pro-Tech Technical Sup-
port is available at the number provided in the Mainte-
nance chapter for advice on some material
combinations.
Excess pressure can damage the laminating rolls.
Minimum laminator roll pressure is consistent
with good results.
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. If not, you will obtain poor results.
