CAUTION
The pull rolls must be at room temperature to
achieve a proper nip setting.
The gap between the two pull rolls is called the nip.
The purpose of adjusting the nip is to ensure
continuous contact between the laminating rolls as
the media is drawn through the machine. This
procedure must be done regularly.
Tools required:
1
/
8
" hex wrench
To adjust the pull roll nip:
WARNING
Use extreme caution when servicing the
laminator with cabinet cover(s) open and
power applied. You could be severely shocked,
electrocuted, or get your fingers caught in the
drive mechanisms.
1. Open both cabinet covers using the
5

" hex
wrench by removing the four screws holding each
cover in place.
2. Make sure that the machine has both power and
air. It is also necessary to ensure that the
up/down rates of the upper pull roll are even
prior to setting the nip. If they are not, follow the
rate adjusting procedure later in this section.
3. Raise the upper pull roll.
4. Set the nip adjuster on each end of the laminator
to zero. View the setting on the interior wall of
the laminator, not from inside the open cabinets.
