6.4 Helpful hints
Good consistent lamination is a result of combining proper
heat, speed, tension and dwell time. Dwell time is the
amount of time the material to be laminated is compressed
between the heat rollers and is controlled by the speed of
the laminator.
As a general rule, thicker items and films as well as items
with dark or full ink coverage, need to run at a slower
speeds because they extract more heat from the rollers at
a quicker rate.
Thinner items, such as standard copier paper (20lb.bond)
and tissue stock, extract less heat from the rollers and can
be run at faster speeds.
Operation of the laminator for more than thirty minutes at
a time may necessitate a lower speed setting. It is
recommended that during periods of long runs the items
being laminated are alternated between thick and thin.
If you are ever unsure that your laminator is set at proper
speed, run a test piece (scrap) of the same or similar
material through the laminator. Rotating the heat rollers
prior to laminating distributes the heat evenly throughout
the heat rollers.
Always change the top and bottom supply rolls at the
same time. This will prevent adhesive from getting on the
rollers. Adhesive will deposit on the rollers if:
– Only one roll of film is used.
– Different widths of rolls are loaded together.
– Either roll is loaded adhesive side against a heat
roller.
– One or both rolls of film are allowed to run
completely off the cores.
Always use the minimum brake tension necessary to
achieve the desired results. Using the maximum amount
will yield unwanted results after close inspection. You may
see stretching, waves in the laminate, distortion of the image
and/ or curling.
6.5 Important points to remember
WARNING: Do not press RUN until READY has
illuminated.
WARNING: To cut film or web, only use the rear
slitter or an enclosed blade around the laminator.
WARNING: Do not force items into the laminator.
An item that is not easily drawn into the laminator is
probably to thick to laminate.
WARNING: Do not attempt to laminate abrasive
or metal objects such as staples, paper clips and
glitter as they may damage the heat rollers.
WARNING: Do not attempt to laminate adhesives
marked “FLAMMABLE”.
CAUTION: Avoid direct contact with the heat rollers
when changing the supply rolls after the laminator
has been running.
