Definitions
- the invention relates to a cylinder of a rotary printing press for lifting a plate according to the preamble of claim 1.
- DE 43 03 381 A1 shows a plate cylinder with a device for lifting a printing plate by means of Compressed air. These are in a lateral surface of the Plate cylinder below the pressure plate to be lifted Openings attached, which can be pressurized with compressed air are.
- a disadvantage of this plate cylinder is that openings arranged in the lateral surface Irregularities in the printed image can occur or the pressure-free zone is enlarged.
- the invention has for its object a cylinder to create a plate.
- the cylinder according to the invention is in the drawing shown and is described in more detail below.
- a cylinder 1 of a rotary printing machine for receiving flexible plates 2 with bent ends 3, 4 with at least one narrow channel running parallel to its axis of rotation and extending from a lateral surface 6 of the cylinder 1 into its interior 7.
- the plate 2 with a thickness d2, z. B. d2 0.3 mm, it is preferably printing plates, for. B. for planographic printing or letterpress printing (in particular flexographic printing, ie carrier plates with a plastic layer) or to carrier plates with z. B. rubber blankets attached to it.
- the leading end 3 and trailing end 4 each have a bent leg 9, 11.
- the channel is approximately rectangular in cross section, in the form of a Slot 12, formed.
- At the The end of the slot 12 is parallel bore 16 in the cylinder 1 extending to the channel appropriate.
- the slot 12 affects the Bore 16 in the form of a chord so that the bore 16 communicates with the slot 12.
- This wave 17 is in axial direction with several radially outwards acting, sprung pressure pieces 18 provided.
- the Thrust pieces 18 are fastened in the shaft 17 in such a way that whose pressure cam 19 over a lateral surface 21 of the shaft 17 can also act resiliently.
- the pressure cams 19 are cylindrical designed so that for each pressure cam 19th results, for example, in a line-shaped contact zone. It it is also possible, for example, to apply the pressure cams 18 to be provided with a ball end at its outer end.
- the channel is used to record the leading end 3 of the plate 2 from one to the opening angle alpha inclined side surface 22 and delimited by an opposite side surface 23.
- the channel points rectangular cross-section and is therefore as Slot 12, which is additionally closed on the end face, executed.
- the slot 12 is provided with a pressure medium supply.
- this can consist of one or two one or both end faces of the cylinder 1 arranged bores 33 exist on which a Pressure medium source is connected.

Description
In vorteilhafter Weise kann ein Ende der Platte vollständig aus dem Schlitz entfernt werden.
Zudem ist eine Zuführung des Druckmittels äußerst einfach ausgeführt.
- Fig. 1
- einen schematischen Schnitt durch den Zylinder.
Bei der Platte 2 mit einer Dicke d2, z. B. d2 = 0,3 mm, handelt es sich vorzugsweise um Druckplatten, z. B. für den Flachdruck oder Hochdruck (insbesondere Flexodruck, d.h. Trägerplatten mit Kunststoffschicht) oder um Trägerplatten mit z. B. darauf befestigten Gummitüchern. Das vorlaufende Ende 3 und nachlaufende Ende 4 weisen jeweils einen abgekanteten Schenkel 9, 11 auf.
Claims (2)
- Zylinder (1) einer Rotationsdruckmaschine mit Austrittsöffnungen (33) zur Zufuhr eines Druckmittels um eine biegsame Platte (2) von einer Mantelfläche (6) des Zylinders (1) abzuheben, wobei die Enden (3; 4) der Platte (2) in einem Kanal (12) angeordnet sind, wobei der Kanal von zwei Seitenflächen (22; 23) und einer Welle (17) begrenzt und mindestens eine in den Kanal mündende Austrittsöffnung angeordnet ist, dadurch gekennzeichnet, daß der Kanal als Schlitz (12) ausgebildet ist und daß die Austrittsöffnung (33) stirnseitig am Zylinder (1) und außerhalb der schwenkbaren Welle (17) angeordnet ist.
- Zylinder (1) nach Anspruch 1 dadurch gekennzeichnet, daß mindestens eine Austrittsöffnung zum Zuführen von Druckmittel im Bereich eines innen liegenden Endes (32) des Schlitzes (12) angeordnet ist.
