Adjustments
Drive Belt Tension
Tension adjustment of the drive belts may be required during normal operation. Belt tension must be adequate to
positively move the box through the machine and they 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 3.5 kg [7 lbs]
applied at the midspan, as shown in Figure 4-4, will deflect the belt 25 mm [1 inch]. This will assure positive
contact between the belt and the drive pulley on the discharge end of the taping head.
To adjust belts, see "Maintenance – Drive Belts", page 20.
WARNING – Turn off electrical power supply and disconnect power cord from electrical supply
before beginning adjustments. If power cord is not disconnected, severe injury to personnel
could result.
