ABSTRACT:
A method and apparatus is disclosed for producing high page count signatures for printed publications. Signatures with a 96 page count and 128 page count are illustrated and described herein. In either case, the signature is constructed of four sheets of printed sheet materials which are preferably continuous webs of sheet material that are fed to a folding and cutting apparatus. The four sheets or webs are folded in half along a main longitudinal fold line extending in the direction in which the web travels. Preferably, the webs are perforated along the main longitudinal fold line prior to being folded. The webs, after being folded in half, are perforated to create a longitudinally extending hinge. Also, the webs are preferably perforated to create cross fold lines. In the case of the 96 page count signature, the folded webs are divided into thirds by the cross fold lines. The folded webs of the 128 page count signature are divided into fourths by the cross fold lines. The webs are then cut into sections which are folded along the fold lines to form the individual signatures.
