Cases are fed, erected, squared and clamped by the machine side belts. As case advances to the bag insertion station, the minor bottom flaps are
folded, while the major flaps remain extended. This method ensures good quality and square cases. The case then moves to the insertion station.

Step 2

Polybags are inserted into the erected cases when they are positioned in the bag inserter section of the machine. Preformed polybags are fed into the
machine from a perforated roll. Air actuated mechanical fingers grip, open and cuff the polybag over
extended upper case flaps.

Air is removed from the case by evacuation. The bag is placed fully by atmospheric pressure, eliminating air pockets between the bag and case. The lined case is bottom sealed and exits machine. The package is ready to be filled.

Step 4

Simplified controls speed start-up and changeover. After case and bag parameters are established, machine operation is fully automatic. All the operator needs to do is add knock down cases and
bag rolls.
