WARNING – NEVER ATTEMPT TO
WORK ON THE TAPING HEADS WHEN
THE BOX DRIVE SYSTEM IS RUNNING.
INJURY TO PERSONNEL OR EQUIPMENT
DAMAGE CAN POTENTIALLY RESULT.
Tape Web Alignment
Refer to Figure 5-1
The HST 3-Inch tape drum assembly is pre-set to
accommodate 3 inch [72 mm] wide tape. The
tape drum assembly is adjustable to provide
alignment of narrower tapes. If adjustment is
necessary to center the tape width on the centerline
of the taping head, (and therefore box center seam),
make adjustment as follows:
1. Loosen the locking hex nut behind tape drum
bracket. Use an adjustable wrench or 25 mm
open end wrench.
2. Turn tape drum shaft in or out to center the
tape web (use 5 mm hex wrench).
3. Tighten locking hex nut to secure the
adjustment.
No other components require adjustment for tape
web alignment.
Friction Brake
Refer to Figure 5-2
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 knurled 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 to minimum
tension that prevents excessive tape roll over travel.
NOTICE
Excess braking force will cause poor tape
applications and lead to tape tabbing on the
trailing tape leg.
