Abstract
Sheet delivery apparatus at a printing machine. The sheet delivery apparatus comprises a chain conveying system for conveying printed sheets to a delivery pile and a suction roller for decelerating the sheets before being deposited on the pile. A suction chamber, positioned below the chain-conveying system, extends over the width of the sheets and up to the suction roller. In the region of the upper sheet layers of the delivery pile, suction boxes are disposed at four lateral pile surfaces.
