Figure 9: Lacquer Container
The lacquer container consists of the top metal roller,
middle silicone rubber roller, bottom silicone rubber
roller, scraper bar and lacquer.
The top and middle rollers are geared and powered by
the laminator’s motor. They are used to grasp the
image being fed into the laminator.
The middle silicone rubber roller applies pressure on
the bottom silicone rubber roller, causing it to rotate
in the lacquer. The bottom silicone rubber roller picks
up the lacquer and transfers it to the middle silicone
rubber roller, which in turn applies the lacquer to the
media. If there is no media present, the middle
silicone rubber roller transfers the lacquer to the top
metal roller. The scraper then scrapes the lacquer
from the top metal roller and transfers it back to the
lacquer container.
The humidity inside the lacquer container is controlled
by the humidity volume adjustment knob, which is
used to maintain the correct viscosity of the lacquer.
See the “Processing Images” section.
Because of the controlled environment, the laminator
can be operated for one week without having to stop
and clean the lacquer container.
The space between the top metal roller and the middle
silicone rubber roller needs to be adjusted to ensure
that the media is receiving the correct amount of
lacquer. This space is called the nip. It is adjusted by
raising or lowering the bottom and middle rollers
using the two roller height adjustment screws located
on the top left and right hand side of the lacquer
container. See the section on “Roller Height
Adjustment.”
The purpose of the drain valve, located on the bottom
of the lacquer container, is to empty lacquer and wash
water from the container at the end of operations. See
the section on “Cleaning the Lacquer Container.”
