Adjustments

WARNING

•To reduce the risk associated with shear, pinch, and entanglement hazards:

−Turn air and electrical supplies off on associated equipment before performing any adjustments, maintenance, or servicing the machine or taping heads.

−Never attempt to work on the taping head or load tape while the box drive system is running.

Tape Latch Alignment

The Latching tape drum assembly is pre-set to accommodate 48 mm [2 inch] wide tape. The tape drum assembly is adjustable to provide alignment of narrower tapes as shown in Figure 5-1.

To adjust the latch to a new tape core width, do the following:

1.Remove screw from the latch.

2.Move to the latch to the position that corresponds to the tape core width.

3.Replace screw in the new latch location.

To adjust or center the tape width on the centerline of the taping head and the box center seam as shown in Figure 5-2, do the following:

1.Loosen the locking hex nut behind tape drum bracket on tape drum shaft. Use an adjustable wrench or 25 mm open-end wrench.

2.Using a 5 mm hex wrench, turn tape drum shaft in or out to center the tape web as shown in Figure 5-2.

3.Tighten locking hex nut to secure the adjustment.

Tape Drum Friction Brake

The tape drum friction brake on each taping head is pre-set for normal operation to prevent tape roll over travel. Should tension adjustment be required, turn the self-locking nut on the shaft to vary compression of the spring. Turn the nut clockwise to increase the braking force, and counterclockwise to decrease the braking force as shown in Figure 5-3. Adjust brake to minimum tension to prevent excessive tape roll over travel.

Note: Excessive braking force will cause poor tape application and may lead to tape tabbing on the trailing tape leg.
