OPERATING INSTRUCTIONS
Roll Adjustments
The vertical adjustment assembly raises and lowers the upper roll assembly to
accommodate various thickness of substrates being ran. Generally, this upper
roll assembly is the only one that requires vertical adjustments; however, in
special cases the lower roll assembly has been made adjustable. These rolls
should never be allowed to be forced together so as to cause damage to the
surface of the rolls. A handwheel
located at one end of the coater connects two
gear box arrangements and is the means of operating this assembly. Turning
this handwheel in the direction as indicated by the tag will adjust the gap
between the upper coating roll and lower coating roll (or lower back-up roll). This
assembly is mounted on top of the machine at the end housing and includes a
coupling to allow the top roll to be adjusted parallel to the bottom roll within a
thousandth of an inch. To parallel the roll, pull the spring-loaded portion of the
coupling back and either turn the single handwheel or turn the shaft to move
either side up and down independently.
NEVER ALLOW COATING ROLLS TO TOUCH.
Sharp materials or
burrs should never be run through the machine with rubber rolls. This would cut
& gouge the rolls.
