Abstract

A device for conveying sheets in a given travel direction includes a conveying head having a vacuum-applying device for removing an uppermost sheet from a pile of sheets and for maintaining the sheet under suction, the conveying head and the uppermost sheet being relatively movable in the given travel direction, the uppermost sheet being held against a sheet-contacting surface of the conveying head under suction, the conveying head having at least one rolling body surrounded by suction air and frictionally engageable with the uppermost sheet for moving the sheet in the given travel direction.
