Bag transfer device

摘要

Apparatus for clamping and transferring to another location a stack of thermoplastic bags or the like wherein the bag walls have varying thicknesses. The apparatus preferably includes sets of clamping jaws for grasping the stack of bags. Each set comprises two pairs of the jaws. One pair is designed to rigidly clamp upon the stack while the other pair is spring-loaded or otherwise adjustable so that it can close differently than the first pair to compensate for the varying bag thicknesses even when the pairs of jaws are closed by the same drive mechanism. Each set of clamping jaws is independent of the other so that they can operate independently if one set were to jam.
