  • Patent number: 4171178
    Abstract: In an apparatus for automatically handling stacks of bags, initially the bags are formed into stacks, each stack is moved onto and along a conveying track and then unloaded from the track to a loading surface. The support surface on the conveying track for the stacks of bags has a number of recesses into which a prong-shaped support member can be inserted for lifting a stack from the track without using a pallet. The prong-shaped support member includes a stripping plate so that by moving the support member transversely of the plate, the stack on the support member can be displaced onto a loading surface. A carriage movable over the conveying track provides the support surface of the stack of bags. The conveying track includes upper rails for moving the carriage from the stack-forming end to the unloading end and lower rails for returning the carriage to the stack-forming end.
