WARNING – Turn air supply and electrical power off and disconnect power cord from power 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 screws 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 in]. 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.

Taping Head Adjustments – Refer to Section II

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