Abstract

An apparatus for depositing sheets in a stack. The advancing edges of the sheets are brought to a halt by abutting stops. Hold down devices located in the region of the stops restrict the rising up of the advancing edges of the sheets against the stops. The hold down devices comprise rough or adhering surfaces on the stops and/or flexible and/or pivotal elements arranged above and extending obliquely over the stack in the direction of sheet advance.
