The invention relates to a sheet-fed printing press having a feeder, a delivery, and at least one sheet guiding cylinder, which is arranged between the feeder and the delivery, has a gripper system, and is assigned a digital printing system and a first sheet guiding system that removes sheets from the sheet guiding cylinder. The object of the invention is to devise a sheet-fed printing press that can be used in a more variable fashion, and with which a particularly wide spectrum of different products can be produced. According to the invention, the object is attained in that 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.
A sheet-fed printing press having a feeder, a delivery, at least one sheet guiding cylinder, which at least one sheet guiding cylinder is located between the feeder and the delivery, and which has at least one gripper system, and a digital printing system, the sheet-fed printing press further having a first sheet guiding system for removing sheets from the at least one sheet guiding cylinder, wherein the first sheet guiding system is configured for one of transferring the sheets to a second sheet guiding system, which second sheet guiding system transfers the sheets to the at least one sheet guiding cylinder, and transferring the sheets to the delivery, wherein the second sheet guiding system is configured as a perfecting system and is switchable between a first perfecting system operating mode, in which the second sheet guiding system feeds the sheets, in a reversed position, to the at least one sheet guiding cylinder and a second perfecting system operating mode, in which the second sheet guiding system feeds the sheets, in a non-reversed position, to the at least one sheet guiding cylinder,
A sheet-fed printing press having a feeder, a delivery, and at least one sheet guiding cylinder, which at least one sheet guiding cylinder is located between the feeder and the delivery, has at least one gripper system, and is assigned a digital printing system, the sheet-fed printing press having a first sheet guiding system for removing sheets from the at least one sheet guiding cylinder, wherein the first sheet guiding system is configured for one of transferring the sheets to a second sheet guiding system, which second sheet guiding system transfers the sheets to the at least one sheet guiding cylinder, and transferring the sheets to the delivery, wherein the first sheet guiding system encompasses the at least one sheet guiding cylinder in a circumferential area that is greater than 180 degrees, and which first sheet guiding system is configured as a chain conveyor system, wherein at least one dryer, configured as one of an infrared dryer and/or as a thermal air dryer, is assigned to the chain conveyor system of the first sheet guiding system, and wherein the second sheet guiding system is configured as a perfecting system and is switchable between a first perfecting system operating mode, in which the second sheet guiding system feeds the sheets, in a reversed position, to the at least one sheet guiding cylinder and a second perfecting system operating mode, in which the second sheet guiding system feeds the sheets, in a non-reversed position, to the at least one sheet guiding cylinder.
