A device is provided for feeding sheets of a sheet stack pressing against front edge stops to a printing cylinder using transport suction devices, which engage a particular uppermost sheet in the area of the sheet rear edge and bring it in a conveyance direction, sheet transport means and sheet acceleration means downstream therefrom being provided between the front edge stops and the printing cylinder. The object of the invention is to provide a device for feeding sheets which occupies little installation space, maybe implemented using simple means, and does not disadvantageously influence the productivity of the machine which processes sheets. The object is achieved according to the invention in that the sheet acceleration means (43) are directly downstream from the front edge stops (7).
A device for feeding sheets (2) of a sheet stack (3) pressing against front edge stops (7) to a printing cylinder (49) having transport suction devices (13, 14), which engage a particular uppermost sheet (2) in the area of the sheet rear edge (2.2) and bring it in a conveyance direction (18), sheet acceleration means (43) being provided between the front edge stops (7) and the printing cylinder (49), characterized in that the sheets (2) may be fed to the sheet acceleration means (43) by the transport suction devices (13, 14).
