UNIFEED ADJUSTMENT
The doctor roll(s) is adjustable on a horizontal plane in relationship to the coating
roll to control the amount of coating being applied. As the doctor roll is adjusted
into the coating roll, less coating will be applied. As the doctor roll is moved away
from the coating roll, more coating will be applied. The adjustment for the doctor
roll is called a Unifeed. It is a single hand wheel that connects two (2) gear boxes
that turn a screw moving the doctor roll on a horizontal plane.
PARALLELING THE UNIFEED ADJUSTMENT
(doctor roll to coating roll)
The unifeed incorporates a spring-loaded coupling just as the single hand wheel
for the substrate gap does. By pulling back the coupling (pictured below), the
doctor roll can be adjusted to parallel the doctor roll to the coating roll.
