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 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 5-4Afor 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

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
