(54) | Zipper bag filling machine |
(57) A system for seriatim filling and separating zipper-Âequipped bags (12) supplied
in a chain has a filling station (B) 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. |
