The invention relates to a device for color transfer according to the preamble of the patent claim.

Such facilities are z. B. by DE-PS 12 40 known.

It is necessary to arrange several recesses around the circumference of a shaft, in which an in Axialrich · ™ direction running bolt is inserted, which serves to secure a roller section.

The invention is based on the object of providing a device for transferring ink from a roller that emits ink an ink-receiving roller with a non-displaceable shaft arranged between these two rollers on which several roller sections are arranged next to one another, which with their color-transferring surface parts are in contact one after the other with the surfaces of the other two rollers stand, to create, in which automatically when the individual roller sections are threaded onto the shaft, which Roll sections are brought to one another in a predetermined angular offset.

The problem is solved by the subject matter of the characterizing part of the patent claim.

The advantages that can be achieved with the invention are, in particular, that even untrained personnel z. B. after Cleaning, repair, etc. - with a number of rollers-

Sections of the shaft can be removed and re-threaded - without having to use the special care Roll sections can thread back onto the shaft with the correct angular offset.

An exemplary embodiment of the invention is described in more detail below with reference to the drawing.

In the figure, an inventive device is for Transfer of parquet in printing machines shown in section.

Is between two side frames 1, 2 of a printing machine a shaft 3 is arranged. Its first shaft end 4 is removably supported via a bearing pin 5 in a bearing block 6 screwed to the side frame 1. A second shaft end 7 of the shaft 3 is with its bearing pin 10 over a The releasable coupling 8 is connected to a drive hub 9 of a gear 11. The drive hub 9 is mounted in a bearing block 12 screwed onto the side frame 2. The gear 11 is in operative connection with the main drive of the printing machine via further drive means (not shown). In a casing 13 of the shaft 3 is at least one rectangular groove 14 extending over an entire useful length L Milled in with a slope angle oC (e.g. 60 °). on the shaft 3 are several (z. B. 20 pieces), z. B. 45 ram wide, circular roller sections 16 aufgefedelt close together. Each roller section 16 consists of a rubber ring - or liner - 17, which is attached to an outer ring 18

is upset. The outer ring 18 is rotatably mounted on an inner ring 21 by means of a ball bearing 19. To the Effect of an eccentric rotation of the roller section 16 on the shaft 3, the inner ring 21 has an eccentric Bore 22. This bore 22 is used to mount the roller section 16 on the shaft 3, with an inner diameter of the inner ring 21 is adapted to an outer diameter of the shaft 3 such that the inner ring 21 is on the Shaft 3 can be moved slightly. The inner ring 21 is provided with a round guide pin protruding into the bore 22 23 provided. This pin is designed in terms of its dimensions so that it fits into the groove 14 as a Puehrungsstift 23 and the inner ring 21 of the roller section 16 secures against rotation. For clamping the roller sections 16 on the shaft 3, the roller sections 16 are clamped between two bushings 24, 26. Clamping nuts press onto the sockets 24, 26 27, 28, which are screwed onto a threaded part 29, 30 each.
