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.
Tape Latch Alignment – Figure 5-1
The Latching tape drum assembly is pre-set to accommo-
date 72mm [3 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.
Note –
To set up 72mm tape drum for 48mm tape,
disassemble tape drum from bracket and install
lock nut between tape drum and bracket as shown
in inset,
Figure 5-3.
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.
Note –
Excess braking force will cause poor tape
application and may lead to tape tabbing on
the trailing tape leg.
