Abstract

A sheet transfer system on a rotary printing press has an apparatus provided beneath the delivered sheets to slow down the sheets at their trailing end by means of conveyor belts which are guided by drive and deflector rollers, and between which, beneath the conveyor belt, there is a suction chamber, whereby even with a tight sheet sequence and high machine speed, a collison of the sheets during the deceleration process is prevented so that the sheets are slowed down and lowered onto the sheet delivery stack.
