ABSTRACT:
An improved apparatus is operable to stack signatures having one edge portion which is thicker than other edge portions of the signatures. The apparatus compensates for the thickness of the one edge portion by flattening the one edge portion and offsetting successive layers in a stack of signatures. The apparatus includes a platform which receives the signatures in an initial orientation. This platform is rotated about a vertical axis to offset a first group of signatures from their initial orientation. The signatures subsequently received on the platform have a relatively thick edge portion offset from the first group of signatures. After a retractable apparatus has been extended over the top of a group of signatures, the platform is raised to press the signatures against the retractable apparatus and thereby flatten the signatures.
