ABSTRACT:
Apparatus for clamping and transferring to another location stacks of bags or other products of varying sizes. The apparatus preferably includes sets of clamping jaws for grasping the stacks of bags. The jaws are designed for movement in more than one direction in substantially the same plane so that mechanisms for delivering and receiving bags can be used even if the bags from one stack vary in size from that in the next stack. Each set of clamping jaws supports as well as clamps each stack of bags, a lower support jaw being extended to a sufficient length to provide such support. The device can also accommodate bags or other products of varying wall thicknesses.
