WARNING
•
To reduce risk associated with shear,
pinch, and entanglement hazards:
- Turn air and electrical supplies off
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.

Applying Mechanism Spring

To obtain access to the spring, remove the taping
head cover (four mounting screws). Replace cover
when fi nished.
The applying mechanism spring, shown in
Figures 5-4A and 5-4B, controls applying and
buffi ng roller pressure on the box and returns
the mechanism to the reset position. The spring
pressure is pre-set, as shown in Figure 5-4A for
normal operation, but is adjustable.
If a tape gap appears on the trailing surface of the
box increase spring pressure. If the front of the box
is being crushed by the applying roller decrease
spring pressure.
Removing the spring end loop from the spring holder
and placing loop in other holes provided, as shown
in Figure 5-4B, will adjust the spring pressure.
One-Way Tension Roller
