8-THEORY OF OPERATION

8.1 Description of the Working Cycle

After having closed the top flaps of the carton, the operator pushes it under the top infeed end in order to avoid the opening of the top flaps. Further push- ing causes the two bottom 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.

The case sealer 800ab-NA has only one (automatic) operating mode with:

-The EMERGENCY STOP BUTTON unlocked

(Figure 8-1)

-The main switch start switch “ON”

(Figure 8-2)

8.3.1 Normal Stop Procedure
