Description

ABSTRACT:
The palletizing and retrieval from palletized storage of stacks of printing works products, folded sheets of paper for example, is facilitated by associating an upper and a lower interleaf sheet with each layer of stacks of the products. This provides a pair of interleaf sheets between adjacent layers of the stacks and the uppermost stack layer may be caused to slide relative to the adjacent lower stack layer by imparting a pulling force to the lower interleaf sheet associated with the stack layer to be moved while applying a restraining force to the upper interleaf sheet associated with the adjacent lower stack layer. Apparatus for use in the practice of the invention provides for withdrawing the interleaf sheets from magazines and feeding them into position as the stack layers are formed and the invention also encompasses apparatus for separating the interleaf sheets from a stack layer being retrieved from storage and directing the separated interleaf sheets to storage magazines.
