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 3-1 and 3-2, 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.
Removing the spring end loop from the spring holder
and placing loop in other holes provided, as shown
in Figure 5-3B, will adjust the spring pressure.
WARNING – Turn air and electrical
supplies off and disconnect before
beginning adjustments. Failure to comply
with this warning could result in severe
personal injury and/or equipment damage.
