So, 0.002" x 5 = 0.010" which is the gap required between the doctor and
coating roll. This may not give you the dry finished thickness required due to the
possibility that not all the coating material passing through the gap is deposited
on the stock being run. A small adjustment of the doctor roll may be necessary
to produce the required dry finish thickness.
ROLL CHANGE OUT:
To remove the coating and doctor roll (s) follow these procedures:
1. Remove seal plates.
2. Remove
“end” covers on both housings

the roll.
