13-MAINTENANCE AND REPAIRS

(continued)

Box Drive Belt Tension

The two (2) 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

Section 11 / Buildup and Adjustments

). 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 infeed 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 [7 lbs.]
applied at the mid span, as shown in

Figure 13-7

, will de

fl

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.

Figure 13-7 Box Drive Belt Tension Adjustment

•

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.
