As already mentioned, the preferred one is the forme cylinder 1 one of the processing tools and can, for example, when using a smoothing plate, be tempered.

The mode of action is as follows: The printed and / or lacquered and / or otherwise coated sheet material is produced by means of the rotatably drivable sheet guiding cylinders 3 . 4 in the conveying direction 16 transported and from a sheet holder 12 of the boom device immediately upstream sheet guiding cylinder 4 to a sheet holding means 12 the rotationally circulating traction mechanism 11 to hand over. This sheet holder 12 promotes in the conveying direction 16 the sheet material substantially horizontally with support of the sheet guiding device 7 in the direction of the contact point of form cylinder 1 and impression cylinder 2 , The sheet holder dives 12 temporarily in the cylinder channel 17 of the rotating forme cylinder 1 one. If necessary, the sheet holding means becomes 12 temporarily in the cylinder channel 17 locked. In the contact point of the rotatably driven form cylinder 1 and impression cylinder 2 the sheet material receives the mechanical processing, depending on the tool used. For example, in the contact point, the sheet material between form cylinder 1 and impression cylinder 2 embossed according to the principle matrix / patrix. If necessary, the lock of the sheet holding means 12 dissolved and then leaves the sheet holding means 12 the cylinder channel 17 ,

The sheet holder 12 on the traction mechanism 11 can in the first training ( 1 . 2 ) the sheet material in the conveying direction 16 over the sheet braking device 14 continue to transport and places this in a conventional manner on the first delivery pile 5 from.

In second education ( 1 . 2 ) can be in the contact point of forme cylinder 1 and impression cylinder 2 the sheet material to a sheet holding means 12 the impression cylinder 2 be handed over and the impression cylinder 2 Pass the sheet material towards the second delivery pile 6 like this DE 198 19 491 C1 is known.

In a third training ( 3 ) can be in the contact point of forme cylinder 1 and impression cylinder 2 the sheet material from the sheet holder 12 the traction mechanism 11 to the downstream transport device 18 be handed over. The transport device 18 can be a first delivery pile 5 be subordinate. Alternatively, the sheet material by means of the transport device 18 be supplied to a downstream processing station.

If necessary, the sheet material may be attached to a sheet holding means 12 the impression cylinder 2 be handed over and the impression cylinder 2 Pass the sheet material in the direction of the second delivery pile 6 out.

When changing the plate-shaped machining tool of the form cylinder 1 in the contact point to the impression cylinder 2 temporarily separated. In the first embodiment is preferably the form cylinder 1 separated from the main drive by means of a clutch and temporarily coupled with the associated single drive. The single drive rotates the form cylinder 1 and positions it in the change position. The machining tool is from the forme cylinder 1 released from the holding means and the forme cylinder 1 is rotated by means of individual drive, so that the machining tool in the direction of the tool changing device 13 can be carried away. Subsequently, the form cylinder 1 stopped and another machining tool is by means of tool changing device 13 the form cylinder 1 fed. The form cylinder 1 is rotated by means of individual drive and the machining tool is on the forme cylinder 1 releasably fixed. Then the coupling to the single drive can be separated and the form cylinder 1 is integrated by means of the clutch in the main drive.
