Important Safeguards
Both the upper and lower taping heads have important safeguards listed below, every person who operates
and/or maintains the heads should be familiar with these safeguards.
The “Warning - Sharp Knife” label is used
on each head to warn operators and service
personnel of the extremely sharp blades used
to cut the tape at the end of the box sealing
operation. The label shown in Figure 1-1 is
located on the blade guard assembly
between the applying roller assembly and the
buffing roller assembly. Before working with
the tape heads or attempting to load the tape,
refer to Figures 4-1 and 4-2 and identify the
knife blade location. Keeps hands out of
these areas except as necessary to
service the taping heads.
The “Tape Threading" labels, shown in
Figure 1-3, are attached to the right side of the
frame on both the upper and lower taping
heads. The top label is for the upper head,
and the bottom label is for the lower head.
These labels provide a convenient tape
threading diagram. More detailed tape loading
and threading information is provided in this
manual in the set-up procedure section.
The “Caution - Keep Hands Out of This
Area” labels, shown in Figure 1-2 is
attached to the frame and located behind the
slide mechanism. The top label is for the
upper head, and the bottom label is for the
lower head. This warns operators to
keep hands and objects out of this area when
the taping head mechanism is in operation.
The taping heads are equipped with an orange
blade guard that covers the blade. The
taping head should never be operated with
the blade guard removed.
Turn air and electrical supplies off before
servicing the taping heads.
The taping heads should not be washed down
or subjected to conditions causing moisture
condensation on components.

Installation (Continued)
BOTH THE UPPER AND LOWER TAPING HEADS UTILIZE EXTREMELY SHARP KNIFE BLADES. THE
BLADES ARE LOCATED UNDER THE ORANGE BLADE GUARD WHICH HAS THE “WARNING – SHARP
KNIFE” LABEL. BEFORE WORKING WITH THE TAPING HEADS OR ATTEMPTING TO LOAD THE TAPE,
REFER TO FIGURES 4-1 AND 4-2 AND IDENTIFY THE BLADE LOCATION. KEEP HANDS OUT OF THESE
AREAS EXCEPT AS NECESSARY TO SERVICE THE TAPING HEADS.
After the taping head assembly has been unpackaged, examine the unit for damage that might have occurred
during transit. If damage is evident, file a damage claim immediately with the transportation company and also
your 3M Representative.
The taping heads can be used to replace existing or custom made machinery. It can be mounted for top taping or
bottom taping. Refer to box size specifications on page 5 and Figure 2-1 on page 6, for the following points in
making such installations:
1. The case conveying system must positively propel the case in a continuous motion, not exceeding 150
feet per minute [45.7 m/min.], past the taping head assembly since the case motion actuates the taping
mechanism.
2. If a pusher or cleated conveyor is being used, steps should be taken in the conveyor design to prevent the
pusher from contacting the applying or buffing roller arms which may result in damage to the taping
head. If this is not possible, contact 3M for assistance or suggested modifications that will provide
adequate operating clearance to the taping head assembly.
3. Figure 2-1 illustrates the typical mounting relationship for opposing taping head assemblies to allow taping
of case heights down to 5.4 inches [135 mm]. To tape case heights down to 4 inches [100 mm], the
taping head assemblies must be completely staggered so only one tape seal is being applied at one
time.
4. Four (4) mounting studs are provided on the taping head side plates but special installations may require
alternate means for mounting. Alternate mounting studs are provided for use with optional HST mounting
frame P/N 78-8062-4234-9. See parts drawing, page 26.
5. The taping head assembly is provided with mounting holes for mounting the tape drum bracket in two
different locations. Normal installation is in the center of the frame. For clearance problems, the front
mounting can be used.
IMPORTANT SAFEGUARDS
Upper Taping Head

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.

Adjustments (Continued)
Buffing Roller Spring Tension
Refer to Figures 5-3 and 5-4
WARNING – USE CARE WHEN
WORKING ON BUFFING ROLLER
ASSEMBLY AS SPRING IS UNDER TENSION.
IF CARE IS NOT TAKEN PERSONNEL
INJURY COULD RESULT.
The buffing roller spring controls the buffing roller
pressure on the box and returns the assembly to the
reset position. The spring tension is pre-set with the
spring end loop in slot “C” for normal operation but is
adjustable.
Should a tape loop appear on the trailing tape leg
application, buffing roller pressure can be increased.
With the buffing roller assembly in reset position,
remove the spring end loop from slot “C” and place
the loop in slot “B” or “A” to increase the spring
tension. (Slot "A" will provide the greatest buffing
roller pressure.)
Should lower buffing forces be required, remove the
spring end loop from slot “C” and place in hole “D”,
“E” or “F” to lower the spring tension. (Hole "F" will
provide the least buffing roller pressure.)
