ABSTRACT:
Polymer composition bags are located in a stack with the holes in the lips of lip bags engaged on wickets. When a stack of bags is so located, it is supported by an anvil, and a tamper foot comes down adjacent the anvil to clamp the stack of bags. A hot needle penetrates the lips on the stack of bags to tack-weld the bags together so that they may be handled as an integral unit, but bags can be individually removed at the bag-filling station.
