Abstract: A device for depositing paper sheets, in particular on a sheet pile or stack in a delivery of a printing machine, includes a revolving belt, a drive motor for driving the revolving belt separately from any other drive system, and at least one suction device having a discretely effective suction action, the suction device being disposed on the revolving belt, the revolving belt being constructed as a toothed belt for transmitting torque and synchronicity between the drive motor and the suction device; and a method of operating the depositing device.

Abstract: A device for the transport and deposit of sheets in a stacking region is provided. The device includes pneumatic guiding elements below the conveying path and extending across the entire width. A chain-conveyor system and a pneumatic conveyor system following the chain-conveyor system are provided. The devices also provides for selectable paths to plural delivery positions.

Abstract: A rotary printing machine with a sheet-surface treating device disposed between a last cyclically operating printing unit and a device for conveying sheets on a sheet pile, the sheet-surface treating device including at least one fixed drier past which the sheets are guidable, includes at least one module composed of two rotating conveying elements having a like circumferential speed for transporting the sheets along the sheet-surface treating device, the conveying elements carrying grippers for grasping a respective leading edge of one of the sheets, the sheets being supplied to the module and discharged from the module, respectively, during a rotation of the grippers in accordance with a printing cycle, a plurality of gripper arms, the grippers of a respective conveying element disposed first along a conveying path of the sheets being carried by at least one of the gripper arms, guiding elements for freely guiding the sheets otherwise, the grippers of the conveying element disposed second along the conveyin
