ABSTRACT:
The delivery suction arms of a transfer mechanism take the individual plastic bag segments to be stacked from a welding and cutting station, swing them to a pin conveyor belt and spindle them on the stack pins of the pin conveyor belt. Three suction arms are positioned next to each other in rows with spacing from each other, two of which grasp an individual plastic bag segment on both sides of pin holes positioned at one end of the individual plastic bags, and in stacking swing past the pin conveyor belt. The remaining or third delivery suction arm grasps the bottom of the individual plastic bag. In the travel direction of the conveyor belt a finishing mechanism is positioned following the delivery mechanism which seals the stacked bags and may provide the bags with handle-holes.
