CONVEYOR BELT TENSION
belt on the drive roller during sanding operation. The
conveyor belt is too loose if it can be stopped by hand
pressure applied directly to the top of the conveyor belt.
Excessive belt tension can result in bent rollers, prema-
ture wearing of the bronze bushings or conveyor belt
the take-up screw nut on both sides of the conveyor
to obtain approximately equal tension on both sides of
the belt when taut (see opposite picture).
CONVEYOR BELT TRACKING
Belt tracking adjustments are made while the conveyor
belt is running.
After the proper belt tension is obtained turn the
conveyor unit on and set it at the fastest speed setting.
Watch for a tendency of the conveyor belt to drift to
one side of the conveyor.
To adjust the belt tracking, tighten the take-up screw
nut on the side the belt is drifting toward, and loosen
the take-up screw nut on the opposite side.
Adjusting the take-up screw nuts on either side of the
conveyor allows belt-tracking adjustments to be made
without affecting belt tension.
Note: Adjust the take-up screw nuts only 1/4 turn at a time. Then allow time for the belt to react to the adjustments
before proceeding further. Avoid over-adjustments.
