The gap between the two main 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
1
/
16
" hex wrench
To adjust the main roll nip:
CAUTION
The main rolls must be at room temperature
to achieve a proper nip setting.
1. Make sure that the machine has both power and
air. It is also necessary to ensure that the
up/down rates of the upper main roll are even
prior to setting the nip. If they are not, follow the
rate adjusting procedure later in this section.
2. Rotate the adjusting collar on each end of the
laminator until it touches the lock collar.
