3E-Stop Switch

The E-Stop switch kills electrical power and exhaust air pressure from the drive belt assemblies. The upper head assembly will raise to its upper most position. To restart machine, rotate E-stop switch (releases switch latch) and then restart machine by pressing electrical switch "I" (On) button on side guard of machine.

4Door

The door is equipped with a safety interlock which kills electrical power and exhaust air pressure from the drive belt assemblies. The upper head assembly will raise to its upper most position when the door is opened.

WARNING – The E-Stop switch or door must not be used for raising

the upper head assembly for maintenance work. If these are used the upper head assembly could lower during maintenance work causing injury to personnel.

5Raising Switch, Upper Taping Head Frame This switch, when touched by the leading edge of a box, pneumatically raises the upper frame to allow insertion of a box under the upper frame, as the box moves under the switch, releasing it, the upper frame descends on the box and the drive belts convey the box through the machine. When switch is actuated by hand, the upper frame rises to its maximum height. Released, the upper frame descends to its rest position.

6Centering Switch, Box Drive Belts

This pneumatic switch controls the closing (centering) of the drive belts. When switch is activated by a box passing under it, the drive belts close and center the box.

7Air Pressure Regulator, Box Drive Belt Centering –Figure3-4.

This regulator is used to adjust drive belt centering pressure. The factory set point is 5 turns clockwise. If more pressure is needed to center box, turn knob clockwise to desired pressure. If box is being crushed, turn knob counterclockwise to relieve pressure. Regulator is locked by tightening screw.

8Air Pressure Gauge, Upper Taping Head Frame

This gauge, used in conjunction with the upper frame air regulator, provides operator with a reference pressure setting for various size/ weight boxes.
