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

•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.
