ABSTRACT:
A system for seriatim filling and separating zipper-equipped bags supplied in a chain has a filling station in which each bag mouth is spread open to permit top filling, a closing station in which the zipper profiles of each filled bag are interlocked, and a separation station in which the filled bag is separated from the chain. A pincer action grasps each filled bag, draws the filled bag through the closing and separation stations, and releases the separated and filled bag for collection. The operation of the pincer serves to bring about indexing of the bags in the chain through the bag filling system. The result is an economical and reliable zipper equipped bag filling method and apparatus.
