US 2020/0223218 A1 · SHEET-FED PRINTING PRESS

Abstract

A sheet-fed printing press has a feeder, a deliverer and at least one sheet guiding cylinder which is arranged between the feeder and the deliverer. The sheet-fed printing press also is a gripper system and is assigned to a digital printing device. A first sheet guiding device receives sheets from the sheet guiding cylinder. The object of the sheet-fed printing press is to provide such a sheet-fed printing press which can be used in a relatively variable manner and by way of which, in particular, a relatively great spectrum of different products can be produced. This object is accomplished by virtue of the fact that the first sheet guiding device is configured for the selective transfer of the sheet to a second sheet guiding device, which transfers the sheets to the sheet guiding cylinder, or for the transfer to the deliverer. The second sheet guiding device is configured as a turner device and can switched over between an operating mode, in which it turns the sheets, and an operating mode, in which it feeds the sheets, in a non-turned state, to the sheet guiding cylinder.

1-24. (canceled)

A sheet-fed printing press having a feeder (1), a delivery (11), and at least one sheet guiding cylinder (3), which is located between the feeder (1) and the delivery (11), has at least one gripper system, and is assigned a digital printing system (4) and a first sheet guiding system (12) for removing sheets from the sheet guiding cylinder (3),

wherein the first sheet guiding system (12) is configured for selectively transferring the sheets to a second sheet guiding system (8), which transfers the sheets to the sheet guiding cylinder (3), or for transferring said sheets to the delivery (11), wherein the second sheet guiding system (8) is configured as a perfecting system (8) and can be switched between an operating mode in which it feeds the sheets in a reversed position to the sheet guiding cylinder (3) and an operating mode in which it feeds the sheets in a non-reversed position to the sheet guiding cylinder, and
wherein the first sheet guiding system (12) is configured as a chain conveyor system and at least one dryer (7) is assigned to the chain conveyor system, and/or wherein the perfecting system (8) has a first transfer cylinder (13) which in one operating mode transfers sheets to a second transfer cylinder (14) and in another operating mode transfers sheets to a perfecting drum (15).
