6. Belt Deviation
Check how belt is deviating before adjustment. Correct positions of the following parts while running
conveyor slowly, and then continue running it for a while to check any further belt deviation.
-Take-up devices: Position and adjust them equally on right and left sides.
-Head and tail pulleys: Set at right angle to frame.
6-2. BELT ALIGNMENT ADJUSTMENT
After checking belt deviation, adjust each part following the procedures on p.19-20 while
running conveyor slowly.
NOTE: It is necessary to wait until belt running stabilizes after each adjustment step and to adjust belt
alignment little by little. Belt running will not change immediately.
1. Adjustment Using Take-up Pulley
On side to which belt is deviating, slightly turn take-up bolt(*1) of drive unit counterclockwise with a
spanner. Take-up pulley(*2) will then move outward on this side and belt will center itself.
Alternatively adjust on opposite side. In this case turn take-up bolt(*1) clockwise. Take-up pulley(*2)
will then move inward on this side and belt will center itself.
