ABSTRACT:
Sheet turnover apparatus of particular utility in the document-delivery system of a high speed printer, copier, or the like. Documents are serially routed through an infeed nip of a three-roller assembly, and received by a narrow, angularly-profiled chute. The chute includes a recoil assembly at its far end, which causes the document to reverse its travel within the chute to be directed toward the outfeed nip of the roller assembly. A paddle or flipper assembly mounted to the central roller of the roller triad directs the trailing edge of the document from infeed nip to outfeed nip, where it becomes the document's leading edge.
