.2 Adjusting front and rear roller
s
Pressure
• Use Screwdriver
to adjust the roller pressure:
C.W – Increase pressure.
C.C.W – Decrease pressure.
1.Using Push-Pull Scale, measure
3 spots as shown on Figure B &C:
Front roller should be 5~6 and back
rollers should be 6~8.
2.Checking for over all tension –
when the machine is running, check that
the top and the bottom films are fed in
without any wrinkles.
3.Pressure mark checking (Heat Line) –
stop the machine for 30 seconds to
create a heat line. Then check to see if
you have two even parallel lines from
one end to other. Note: A narrow parallel
lines indicate that it has less pressure
at that point.
4.Laminating Test – Laminate samples
with different thickness of substrates.
5.Check above steps 2 through 4 with
3mil & 5mil films.
