13. Maintenance and Repairs
13.11 Box Drive Pulley Rings
Before installing a new belt, check
the orange plastic drive pulley rings
for wear. If torn, broken, or worn
smooth, replace the rings (Figure 13-3).
13.12 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 Adjust-
ment - 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 infeed end are adjusted in or
out to provide proper belt tension.
Each belt is adjusted separately.
Belt tension is obtained by tight-
ening the adjustment screw so
that a moderate pulling force of
3.5kg [7lbs.] applied at the mid
span, as shown in Figure 13-4,
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.
