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 push-
ing causes the two top and bottom 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  Definition of Running Mode
The case sealer 
700a has only one (automatic) 
operating mode with:
-  The EMERGENCY STOP BUTTON unlocked
 
(Figure 8-1)
-  The main  switch start switch “ON” (I)
 
(Figure 8-2)
8.3.1  Normal Stop Procedure
When the main switch is turned OFF (O), 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.
