STEP FOUR OF WEBBING PROCEDURE: _________________________________________________________
*
IMPORTANT: The Cooling Fan Bank must be on for this process because of the high temperatures to ensure quality output.
•
Lower the top main and pull rollers.
•
Reduce the amount of tension on the lower
rear take-up shaft by backing off the
adjustment collar. This will prevent bubbling
that might occur between the two chill idlers
when excessive tension from the lower rear
take-up shaft pulls the film before it can be
properly cooled off.
•
If during operation this bubbling can not be
eliminated by this method, raise the top pull
roll and then lower again. Continue to run
and this should remedy this problem.
•
Turn the motor on and run the prints
through the rollers checking the quality of
the output.
•
Minimize adjusting the motor speed during
the run of the transfer process. This may
cause wrinkles feeding into the nip of the
main rollers. It is best to set the desired
speed at the start.
•
It is recommended that if you want to
change the speed drastically during the
operation, stop the motor and raise the top
roller. Adjust the speed setting and lower
the top roller to reestablish good output.
•
Adjust the tension of the brakes on the front
top and bottom unwind shafts and the rear
roll easel shaft. Make sure the output is free
of wrinkles and tracking properly.
