Operation (Continued)
2. Once the box is centered by the guides, the
operator pushes the box against the raising
switch on the upper drive assembly, as shown in
Figure 3-8, two air cylinders raise the upper drive
assembly. The upper taping head will continue
to rise above the box height so the operator can
insert the box underneath the upper drive belts.

• To reduce the risk associated with pinches
and entanglement hazards:
−Keep hands clear of the upper head support
assembly as boxes are transported through
the machine
CAUTION
Tape Loading/Threading
See Section II.
The air supply powers movement of the centering
guides and upper drive assembly to automatically
adjust the case sealer to the box size being sealed
as follows:
1. A box centering switch in the center of the
infeed roller conveyor actuates movement of the
centering guides. When the operator pushes a
box onto the infeed conveyor, as shown in
Figure 3-7, the lever is depressed causing the
air cylinder powered centering guides to move
inward, centering the box.
WARNING
•To reduce the risk associated with muscle
strain:
−Use proper body mechanics when removing
or installing taping heads that are moderately
heavy or may be considered awkward to lift.
Theory of Operation
• To reduce the risk associated with pinches
and entanglement hazards:
−Always feed boxes into the machine by
pushing only from the end of the box.
−Keep hands clear of the upper head support
assembly as boxes are transported through
the machine.
•To reduce the risk associated with pinches
and impact hazards:
−Keep away from the pneumatically controlled
upper drive assembly and box centering
guides when air and electric supplies are on.
