Abstract: A rotary printing machine includes at least one form cylinder, at least one further cylinder, and a gear transmission via which the form cylinder and the further cylinder are drivable together during a printing operation. A device is provided for setting an image on a printing form located on the form cylinder. A switchable speed-change gear mechanism is disposed between the form cylinder and the gear transmission for driving the form cylinder during the printing operation.

Abstract: A method for driving a printing press includes driving, in a printing operation, via a gear train by at least a first motor, at least one drum for advancing printing material and a printing-form cylinder, processing angle-of-rotation signals of the drum in a control device for controlling the driving of the drum and the form cylinder, and driving, in a printing-form production operation in the printing press, a printing-form cylinder by a separate motor. The method further includes, in an operation for producing the printing form, synchronously actuating the first motor and the separate motor by providing a gear allocated to the driving of the printing-form cylinder, and an adjacent gear allocated to the driving of the drum of the gear train, the gears being disposed relative to one another at the most out of contact with one another, and at the least barely in engagement with one another so as to exert a slight pressure on one another, and a device for performing the method.

Abstract: A novel, inexpensive and compact printing press is provided, having a central plate cylinder (1) including at least two printing plates (5) mounted on the peripheral side, around which are arranged in a satellite configuration at least two blanket cylinders (3) having assigned inking units (7), including a transport device (13), which loops around the blanket cylinder (3) on the outside, in the manner of a closed, continuous belt, having printing sheets, which are pressed for the printing operation by compensating rollers (15) against blanket cylinders (3), and having a control unit (11), which engages the particular inking unit (7) and the blanket cylinder (3) on the corresponding printing plate (5) and lifts it off of the other printing plate(s) (5).

Abstract: An apparatus is provided for guiding a print carrier upon feeding the print carrier to and guiding the print carrier away from a form cylinder of a rotary printing machine. Guide elements for the print carrier are disposed axially parallel to the form cylinder. The guide elements are disposed in two groups. One group serves to pull the print carrier into the printing unit, while the other group assists in the removal of the print carrier from the printing unit of the rotary printing machine. The guide elements assisting the feeding-in and exchanging of the print carrier are protected against contact with the print carrier by throw-on elements during exchange of a print carrier. A printing unit in a rotary printing machine having the apparatus is also provided.

Abstract: A printing-unit accessory engaged with a printing unit of a printing press, in an operating position of the accessory, and removed from the vicinity of the printing unit, in at least one maintenance position of the accessory, includes a pivoting mechanism securing the accessory to the printing press, the pivoting mechanism being disposed in a region of a side wall of the printing unit in a manner that the accessory is movable into a vertical position adjacent the side wall, and at least one linear guide disposed in front of the side wall so that the accessory is displaceable into a horizontal position thereof distal from the printing unit.
