Abstract: A cleaning device for surfaces of cylinders of a printing machine is provided, having at least one nozzle 23 with a nozzle opening 4 for a jet of cleaning fluid 13, a distribution line 22 for cleaning fluids, in which the nozzle 23 is inserted, as well as a cleaning element 20 for lifting contaminants, dissolved by the cleaning fluids, off the surface of the cylinder. The nozzle 23 is embodied as a separate component and detachably inserted in the distribution line 22. The nozzle 23 is made from a soft-elastic material. The nozzle 23 is provided with a deflector surface 6 arranged downstream from the nozzle opening 4 for deflecting and fanning a jet 13 exiting the nozzle opening 4, as well as a base 1 for inserting it into a distribution line 22, and a channel 11, which extends, on the one side, to a base opening 3 and, on the other side, to the nozzle opening 4. Furthermore, the invention relates to a nozzle for insertion in such a cleaning device.

Abstract: A device for cleaning cylinders of a printing machine is provided, with the device being provided with a driven washing roller 2 to contact a cylinder 1 to be cleaned. A doctor blade 4 at least temporarily engages the surface of the rotating washing roller 2. A collection trough 6 is provided for the dirt scraped off the rotating washing roller 2 by a doctor blade 4. The doctor blade 4 is mounted in the collection trough 6. The collection trough 6 is movably mounted in reference to the washing roller 2 such that the doctor blade 4 can contact the washing roller 2 or can be moved away from it, when necessary, by a respective movement of the collection trough 6.

Abstract: A cleaning system for cylinder surfaces of a printing machine, having a number of automated cleaning devices 1, 1?, 1? allocated to a one or more cylinders, each having a supply line 4, 4?, 4? for the supply of detergent 3, as well as a common feed pipe 5 for the supply lines 4, with at least one supply device being allocated to the feed pipe 5. The supply device includes a piston—cylinder unit 9 and the piston cylinder unit 9 and a detection unit 17, 18, 19 for controlling the piston stroke is provided.

Abstract: A method and apparatus for cleaning cylinders of a printing press with at least one automated washing device (1), which is controlled by a controller (2) with a washing sequence program, which can be selected automatically or manually and which also can be started automatically, delayed, or manually. According to the invention, there is a sensor (3), which interacts with the controller and which scans the surface of the cylinder to be cleaned or the print substrate (4) leaving the cylinder using a non-contact method.

Abstract: The invention concerns a method and a device for cleaning guide rollers of a web printing press having a printing material web guided by a number of guide rollers, wherein cleaning liquid is applied onto the printing material web, is transported and transferred by same to the guide rollers and wherein the guide rollers to be cleaned are decelerated or accelerated while the printing material web is running, to generate slippage for removing the soiling. The printing material web is guided along a container for applying the cleaning liquid such that it has direct contact with the cleaning liquid contained in the container and thus automatically accepts cleaning liquid. In a preferred fashion, the sealing lip is elastically deformable for passing the cleaning liquid to the printing material web.

Abstract: A procedure for fully automatic cleaning of cylinders in printing presses that are fitted with a central control system and automated wash devices, with an expansion of the central control system, by means of which the operating parameters for determining the optimal wash sequence programs for each individual wash device are determined by accessing the central printing press control system, the optimal wash sequence programs for each individual wash device are determined automatically, and the individual wash devices are controlled in each instance by the appropriate optimal wash sequence program.
