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. 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.
