Ein Druckwerk 01 einer Rotat i onst i ef druc kmaschi ne besteht im wesentlichen aus einem Presseur 02, einem Formzylinder 03 und einer Farbauftrageinr chtung. Zwischen Presseur 02 und Formzylinder 03 wird ein Bedruc kstof , beispielsweise eine Bahn 06 im Tiefdruckverfahren bedruckt. Der Formzylinder 03 ist beidseitig mit Zapfen 07 versehen.A printing unit 01 of a rotary printing machine essentially consists of an impression cylinder 02, a forme cylinder 03 and an inking device. A printing material, for example a web 06, is printed between gravure 02 and forme cylinder 03 using the gravure printing process. The forme cylinder 03 is provided with pins 07 on both sides.
Die Zapfen 07 des Formzylinders 03 sind jeweils mittels einer Lünettenlagerung 08 bezüglich eines Seitengestelles 09 der Rotat i onst i ef druc kmaschi ne gelagert.

In order to change the forme cylinder 03, the third support roller 13 of the steady rest bearing 08 is first pivoted away. The carriage 42 moves into a lifting position so that the two-armed lever 38 can engage under the pin 07 of the forme cylinder 03. The working cylinder 41 of the two-armed lever 38 is retracted and the scha lenf örmi ge receptacle 39 of the lever 38 lifts the forme cylinder 03. The drive motor 51 of the chain 52 is actuated and moves the carriage 42 with the raised forme cylinder 03 out of the side frame 09 in the direction of the elevator 44. The carriage 42 reaches the elevator 44 via the folded-down rail pieces 48. The pins 07 of the forme cylinder 03 are moved over the carriers 47 of the elevator 44 are positioned and the drive motor 51 of the chains 52 is switched off. To put down the forme cylinder 03, either the working cylinder 41 of the receptacle 39 of the carriage 42 is extended or the carrier 47 of the elevator 44 is moved upwards.

Dazu ist die Transporteinrichtung 42 so weit verfahrbar, daß die Aufnahme 39 der Transporteinrichtung 42 unter den Presseur 02 gelangt. Die Schienen 43; 48 der Transporteinrichtung 42 sind dabei an der Innenseite des Seitengestelles 09 angeordnet.Each forme cylinder 03 is assigned a linearly movable transport device 42, which can be positioned by means of an actuator 51. This transport device 42 can be provided with a lifting device 37. It is also possible to design the steady rest bearing 08 as a lifting device. This transport device 42 can also be used to change the respective impression roller 02 assigned to the forme cylinder 03. For this purpose, the transport device 42 can be moved so far that the receptacle 39 of the transport device 42 comes under the impression roller 02. The rails 43; 48 of the transport device 42 are arranged on the inside of the side frame 09.
Diese Zyl nderwechseleinrichtung und die Lünettenlagerung kann auch für andere austauschbare Zylinder einer Rotationsdruckmaschine verwendet werden. This cylinder changing device and the steady rest can also be used for other interchangeable cylinders of a rotary printing press.
