Adjustments

WARNING

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

-Turn air and electrical supplies off associated equipment before perform- ing 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 – Figure 5-1

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

To move the latch to a position that corresponds to a new tape core width (Figure 5-1):

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 therefore box center seam,

(Figure 5-2):

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

2.Turn tape drum shaft in or out to center the tape web (use 5mm hex wrench).

3.Tighten locking hex nut to secure the adjustment.

No other components require adjustment for tape web alignment.

Tape Drum Friction Brake – Figure 5-3

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. Adjust brake to minimum tension to prevent excessive tape roll over travel.

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