The two rubber cylinders 4, 6 form a printing point 7 in their contact zone, in which a material web 8, for example a paper web 8, is printed.
Diese Platten- und Gummi zy l i nde r 2, 3, 4, 6 sind an beiden Enden mit Zapfen 9, 11 - 14, 16 - 18 versehen, die in Seitengestellen 19, 21 derThese plate and rubber cylinders 2, 3, 4, 6 are provided at both ends with pins 9, 11 - 14, 16 - 18, which in side frames 19, 21 of the
Off set rotat ionsdruckmaschi ne gelagert sind. Platten- und Gummi zy li nder 2, 3, 4, 6 sind in bekannter Weise, beispielsweise mittels Exzenterbuchsen, an- und abstellbar angeordnet. Beispielsweise können die Gummi zy l i nde r 4, 6 bezüglich der zugehörigen Plattenzylinder 2, 3 an- und abstellbar angeordnet sein. An einer Antriebsseite der Druckeinheit 1 reichen die Zapfen 9, 12, 14, 17 der Platten- und Gummi zy li nde r 2,Off set rotary printing presses are stored. Plate and rubber cylinder 2, 3, 4, 6 are arranged in a known manner, for example by means of eccentric bushings, on and off. For example, the rubber cylinders 4, 6 can be arranged on and off with respect to the associated plate cylinders 2, 3.

4, 6 werden von einem gemeinsamen Antrieb 24, beispielsweise einem lagegeregelten Elektromotor 24 angetrieben. Der Rotor dieses E lekt romotores 24 ist beisp elsweise direkt, d.h. ohne Übersetzung, beispielsweise mittels einer Kupplung an einem Gummizylinder 6 angeordnet, aber der Antrieb 24 kann auch an jedem beliebigen der Gummi zy l i nder 4, 6 direkt oder indirekt, z. B. über ein Getriebe (Zahnrad oder Riemen) vorgesehen sein.4, 6 are driven by a common drive 24, for example a position-controlled electric motor 24 driven. The rotor of this electric motor 24 is, for example, arranged directly, ie without translation, for example by means of a clutch on a rubber cylinder 6, but the drive 24 can also on any of the rubber cylinders 4, 6 directly or indirectly, for. B. be provided via a gear (gear or belt).
Die beiden Plattenzylinder 2, 3 sind jeweils mit einem eigenen Antrieb 26, 27 versehen, der beispielsweise als lagegeregelter Elektromotor 26, 27 ausgeführt ist. Auch hier kann der Antrieb des jeweiligen Plattenzylinders 2, 3 direkt oder über ein Getriebe erfolgen. Der Antrieb 24 der Gummi zy l i nde r 4, 6 und die Antriebe 26, 27 der zwei Plattenzylinder 2, 3 sind zueinander synchroni s i ert .The two plate cylinders 2, 3 are each provided with their own drive 26, 27, which is designed, for example, as a position-controlled electric motor 26, 27. Here too, the respective plate cylinder 2, 3 can be driven directly or via a gear. The drive 24 of the rubber cylinders 4, 6 and the drives 26, 27 of the two plate cylinders 2, 3 are synchronized with one another.
Es ist möglich, an einen der beiden Gummi zy l i nder 4, 6 ein drittes Paar Platten- und Gummi zy l i nde r anzustellen. Dabei bildet der dritte Gummi zy l i nde r mit dem zweiten oder ersten Gummi zy l i nder eine zweite Druckstelle. Auch der dritte Gummi zy l i nde r ist dann mit einem Zahnrad versehen, das z. B. in das Zahnrad des zusammenwirkenden Gummizylinders eingreift. Der dritte Gummi zy l i nde r ist mechanisch, z. B. formschlüssig an den ersten und zweiten Gummi zy li nder gekoppelt.It is possible to place a third pair of plate and rubber cylinders on one of the two rubber cylinder 4, 6. The third rubber cylinder forms a second pressure point with the second or first rubber cylinder. The third rubber cylinder is then also provided with a gear which, for. B. engages in the gear of the interacting rubber cylinder. The third rubber cylinder is mechanical, e.g. B. positively coupled to the first and second rubber cylinders.
Der dritte Plattenz linder ist wiederum mit einem eigenen lagegeregelten Elektromotor versehen und somit einzeln angetrieben. In einem zweiten Ausführungsbeispiel ist eine Druckeinheit 28 in sogenannter H-Bauweise dargestellt. Bei dieser Druckeinheit 28 sind vier Platten- und Gummi zy li nder 29, 34; 31, 36; 32, 37; 33, 38 vorgesehen, von denen jeweils zwei Gummi zy l i nder 34, 36 bzw. 37, 38 aneinander anstellbar, die Bahn 8 bedruckend angeordnet sind. Diese beiden zusammenwirkenden Gummi zy l i nder 34, 36 bzw. 37, 38 sind jeweils gekoppelt und werden von jeweils einem Antriebsmotor 39, 41 angetrieben. Es ist aber auch möglich, alle vier Gummi zy l i nder 34, 36, 37, 38 zu koppeln und diese vier gekoppelten Gummi zy L i nde r 34, 36, 37, 38 mittels eines gemeinsamen Antriebsmotors anzutreiben.The third Plattenz cylinder is in turn provided with its own position-controlled electric motor and thus driven individually. In a second embodiment, a so-called H-type printing unit 28 is shown. In this printing unit 28, four plate and rubber cylinders 29, 34; 31, 36; 32, 37; 33, 38 are provided, of which two rubber cylinders 34, 36 and 37, 38 are adjustable against each other, the web 8 are arranged printing. These two cooperating rubber cylinders 34, 36 and 37, 38 are each coupled and are each driven by a drive motor 39, 41. However, it is also possible to couple all four rubber cylinders 34, 36, 37, 38 and to drive these four coupled rubber cylinders 34, 36, 37, 38 by means of a common drive motor.
Hierbei weist jeder Plattenzylinder 29, 31, 32, 33 einen eigenen, von den Gummi zy l i nde rn 34,36, 37, 38 unabhängigen Antriebsmotor 42, 43, 44, 46 auf.Each plate cylinder 29, 31, 32, 33 has its own drive motor 42, 43, 44, 46, which is independent of the rubber cylinders 34, 36, 37, 38.
In einem dritten Ausführungsbeispiel ist eine Druckeinheit 47 als sogenannter 9-er Satellit ausgebi Ldet.In a third exemplary embodiment, a printing unit 47 is designed as a so-called 9-series satellite.
Bei dieser Art von Druckeinheit 47 sind vier Platten- und Gummizylinder 48, 53; 49, 54; 51, 56; 52, 57 paarweise mit einem als Gegendruckzylinder 58 wirkenden Satellitenz linder 58 zusammenwirkend angeordnet.
