ABSTRACT:
A signature handling apparatus includes a first conveyor which sequentially moves signatures to a discharge station. At the discharge station, the signatures are sequentially transferred to a receiving conveyor. A corrugator assembly is located at the discharge station to stiffen the signatures by forming corrugations which extend between leading and trailing end portions of the signatures. Although the corrugations are only temporarily maintained in the signature, the corrugator assembly is close enough to the receiving conveyor so that a corrugation is maintained in a signature as a leading end portion of the signature moves to the receiving conveyor. Thus, the corrugator assembly is spaced from the receiving conveyor by a distance which is less than the distance between the leading and trailing end portions of the signatures.
