8. Theory of Operation
8.1 Description of the Working Cycle
After having closed the top aps of
the carton, the operator pushes it
under the top infeed end in order to
avoid the opening of the top aps.
Further pushing 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 De nition of Running Mode
The case sealer 7000a-7000a3 Pro
has only one (automatic) operating
mode with:
- The EMERGENCY STOP
- The main On/O switch

When the main switch is turned
OFF (O), the machine 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.
The LATCHING EMERGENCY
STOP BUTTON is located on
the top center of the machine
(Figure 8-3).
