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.
