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 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.
