8-THEORY OF OPERATION

8.1 Description of the Working Cycle
After having closed the top fl aps of the carton, the
operator pushes it under the top infeed end in order
to avoid the opening of the top fl aps. Further pushing
causes the two side belts to drive the box through
the taping heads which automatically seal the top
and bottom seams. The carton is then expelled on
the exit conveyor.
8.2 Defi nition of Running Mode
The case sealer a80f has only one (automatic) oper-
ating mode with:
- The EMERGENCY STOP BUTTON unlocked
(Figure 8-1)
- The main rotary switch "ON"
(Figure 8-2)

8.3.1 Normal Stop Procedure

When the rotary main switch is turned OFF, the ma-
chine stops immediately at any point of the working
cycle. The same thing happens in case of electrical
failure or when the machine is disconnected from the
mains.

8.3.2 Emergency Stop

The latching EMERGENCY STOP BUTTON is
located on the machine frame.
