Abstract

A sheet deliverer adapted for use with rotary printing machines includes a continuous chain having gripping members carried thereon for gripping the leading edge portions of printed sheets and delivering the printed sheets to a product collection site, at least the downstream section of the continuous chain being substantially horizontally disposed above the product collection site. Guide yokes are provided to supplement a developed air cushion on the undersides of the printed and are adjustable so as to contact the printed sheets only at the print-free margins thereof to prevent destruction of the printed portions of the sheets during conveyance.
