Abstract
A stacker for sheet material has a stacker drum. The stacker drum receives sheets from a transport system at a first tangential position and arcuately moves them to a stop at a second tangential position against which the stack is formed. The stacker drum has a row of suction openings for gripping the leading edge of the sheets followed by compressed air openings. The compressed air openings are positioned behind the suction openings sufficiently far so that the compressed air is applied to the sheets only after the leading edges have been run up against the stop.
