    摘要: A device for automatically changing printing plates is provided in a printing machine having a plate cylinder to which a printing plate is to be fed and on which the printing plate is to be fixed detachably. The device includes a transport system for conveying the printing plate while permitting axial compensating movements thereof. The transport system has at least one driven transport roller and an air cushion for holding the conveyed printing plate in contact with the transport roller. The plate-holding air cushion is formed between a counterpressure element, on one side, and the printing plate, on the other side.

    摘要: A printing press has a printing unit with a cylinder and a cleaning device that is mounted for selective displacement into an operating position for cleaning the cylinder and into a maintenance position away from the cylinder. The operating position is located within the printing unit and the maintenance position, although being located outside the printing unit, is located on the press. While the press runs in printing operation, the cleaning device is kept away from the operating position.

    摘要: A rotary lead-through assembly supplies an operating fluid to a rotor of a machine for processing printing material. An operating cylinder includes an expansion chamber and a piston having a piston outlet opening. The piston is mounted so as to be displaceable towards the rotor for coupling a rotor inlet opening and the piston outlet opening with one another. A pressure generator is connected both to the expansion chamber and to the rotor, when the openings are coupled with one another. A threshold value valve is disposed between the expansion chamber and the piston outlet opening. The valve is automatically openable when a given threshold value of an excess pressure of the operating fluid is exceeded. A machine for processing printing material is also provided.

    摘要: A printing press includes a printing form cylinder, a blanket cylinder, an impression cylinder, an adjusting device for setting a printing pressure between the blanket cylinder and the impression cylinder, a control device for throwing the pressure of the blanket cylinder on and off relative to the impression cylinder and springs for producing bearer ring pressure between bearer rings of the printing form cylinder and bearer rings of the blanket cylinder. The springs are integrated into coupling links and are connected to at least one of the two devices in such a way that, as a result of the actuation of that device, the springs are also adjusted, in order to keep the bearer ring pressure at least substantially constant.
