ABSTRACT:
A chain of plastic bags having zipper-locking profiles is compactly stacked in a rectangular carton in successive layers such that the bags of the chain lie flat in the carton and the zipper profile portions of successive bags in chain do not lie on top of one another by means of an automatic apparatus. The apparatus comprises an oscillating guideway for laterally depositing the bags of the chain in rows extending back and forth between opposed lateral sidewalls of the carton and a vertically movable lift table having a horizontally reciprocating platform on which the carton is disposed. The lift table operates to lower the carton beneath the guideway as the carton is being filled and to move the carton transversely of the guideway so that the zipper profiles of successive bag rows are disposed offset from one another.
