Adjustments

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.

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 21, steps 3 and 7.

Taping Head Adjustments

WARNING – Use care when working near tape cut-off knives on taping heads as knives are extremely sharp. If care is not taken, severe injury to personnel could result.
