13.10 Box Drive Belt Tension
The four (4) continuously moving drive belts convey boxes through the tape applying mechanism.
The box drive belts are powered by an electric gear motor.
Tension adjustment of these belts may be required during normal operation (for Belt Tension Adjustment - refer to
Box Drive Belt Replacement). Belt tension must be adequate to positively move the box through the machine
and the belts should run fully on the surface of the pulleys at each end of the frame. The idler pulleys on the in-
feed end are adjusted in or out to provide proper belt tension. Each belt is adjusted separately.
Belt tension is obtained by tightening the adjustment screw so that a moderate pulling force of 3.5kg [7lbs.]
applied at the mid span, as shown in Figure 13-7, will defl ect the belt 25mm [1 inch]. This will assure positive
contact between the belt and the drive pulley on the discharge end of the drive assembly.

• To reduce the risk associated with mechanical and electrical hazards:
Turn electrical supply off and disconnect before performing any adjustments,
maintenance or servicing the machine or taping heads.
