Applying Mechanism Spring
To obtain access to the spring, remove the taping
head cover (four mounting screws). Replace cover
when finished.
The applying mechanism spring, shown in
Figures 5-4A and 5-4B, controls applying and buffing
roller pressure on the box and returns the
mechanism to the reset position. The spring
pressure is pre-set, as shown in Figure 5-3A 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.
To adjust the spring pressure, remove the spring end
loop from the spring holder and place loop in other
holes provided, as shown in Figure 5-3B.
Figure 5-4—Applying Mechanism Spring
To adjust tension, do the following:
1. Wrap a non-adhesive cord or small strap 4-6 turns
around the tension roller as shown in Figure 5-5.
2. Attach a spring scale to the end of the cord or
strap.
3. Turn the adjusting nut with the socket wrench
provided, until a force of approximately 0.5 kg to
0.9 kg [1 to 2 lbs.] is required to turn the roller by
pulling on the spring scale.
One-Way Tension Roller
The one-way tension roller is set at the factory.
When replacing this assembly, the roller must have
0.5 kg [1 lb.] minimum tangential force when turning.

•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.
