ABSTRACT:
An apparatus for stacking and delivering double bags of plastic film receives the bags from a transfer device at a stacking station which includes vertical pins on which the bags are impaled to form a stack. A stack conveyor with built-in grippers moves a completed stack to a severing station where a heated knife separates the double bags lengthwise of their travel while they are still in the grip of the grippers. The severed bags are then transferred to a delivery station where the grippers are released. The conveyor has separate side-by-side runs and separate gripper jaws are carried on each run. The stacking pins and the severing knife are located between the conveyor runs.
