In Fig. 1 and the Figures 2a-c the rings 3, 4 are shown, which are part of the rotary screen printing screens 1 according to the invention.

In FIG. 1 a second ring 4 is shown in a three-dimensional view. The second ring 4 has three clamping elements 5, two of which can be seen in the view. In its outer circumferential surface, the second ring has a recess 14. As is apparent from FIG. 2a results, the second ring 4 is connected to a first ring 3 of larger diameter. For alignment of first ring 3 and second ring 4 to each other, the first ring 3 is provided with a positioning pin 13 which can engage in the recess 14 of the second ring 4. The so positioned relative to each other in their angular position rings 3, 4 are connected to each other by means of the clamping elements 5. In the illustrated embodiment, the clamping elements 5 as in the detailed representation of Figure 2c can be seen as clamping disks 8 executed. A respective clamping disc 8 is connected via a press fit 10 with a hexagon socket 9, about which a respective clamping disc 8 can be rotated. A respective clamping disc 8 can engage in a groove 11 in the first ring 3. The groove 11 of the first ring 3 is executed in the illustrated embodiment as an undercut. How out FIG. 2a can be seen, a respective clamping plate 8 has a portion 12 with reduced diameter. While the two upper clamping discs 8 are in a rotational position in which they engage in the groove 11, the lower clamping disc 8 is in a rotational position in which it does not engage in the groove 11. If all clamping discs 8 are rotated in such a rotational position, the first ring 3 and second ring 4 can be separated from each other. For clamping of the first ring 3 and second ring 4 all clamping disks 8 must be rotated in a rotational position in which they protrude beyond the outer diameter of the second ring and can engage in the groove 11 of the first ring 3. In order to avoid unwanted rotational movement of the clamping plates 8 due to vibrations, a spring washer 15 is provided between a respective clamping disc 8 and its bearing surface in the second ring 4.

In the FIGS. 3a and b or c and d, two completely assembled rotary screen printing screens 1 are shown. A respective rotary screen printing screen 1 consists of a sleeve-shaped screen structure 2 in which a first ring 3 is inserted at both ends. A respective first ring 3 and the sleeve-shaped screen structure 2 are firmly connected to each other and are glued together. In a respective first ring 3 engages in each case a second ring 4, which, as shown in the FIGS. 2a to c described, is connected by means of clamping elements 5 with the first ring 3. The first ring 3 in each case has an outer diameter d1, which corresponds approximately to the diameter of the sleeve-shaped screen structure 2. The inner diameter d2 of the first ring 3 is approximately the same size as the outer diameter d3 of the second ring 4. This makes it possible for a respective first ring 3 to be mounted on a uniform second ring 4 independently of its variable, application-dependent outer diameter d1. While in the FIGS. 3a and b a rotary screen printing screen 1 with a lower printing length and thus smaller outer diameter d1 of the first ring 3 is shown, show the FIGS. 3c and d Regardless of the printing length and its outer diameter d1 of the first ring 3, regardless of the printing length and its outer diameter d1 of the first ring 3, the units of sleeve-shaped screen structure 2 and end-mounted rings 3 can be mounted on identically designed second rings 4 , This makes it possible for different print jobs only a small number of second rings. 4 must be kept ready.
While that in the FIGS. 3a and b shown rotary screen 1 has a smaller printing width b1, has the rotary screen 1 of the FIGS. 3c and d a larger print width b2. It can be seen that the structure of the rotary screensters 1 and their support structures of first ring 3 and second ring 4 is independent of the printing width.

In the FIGS. 4a and b two rotary screen printing screens 1 are shown, which each have the same outer diameter d1 and the same printing width b1. However, a respective second ring 4 has a different configuration: Thus, a respective second ring 4 according to the in FIG. 4a illustrated embodiment, a drive flange 6 of the first embodiment and a respective second ring 4 according to the in FIG. 4b illustrated embodiment, a drive flange 7 second embodiment. The drive flanges 6, 7 are formed depending on the requirements or the design of the drive of a respective rotary screen printing unit in which the rotary screen printing screen 1 is to be used. By an appropriate choice of second rings 4 with appropriately designed drive flanges 6, 7, a unit of sleeve-shaped screen structure 2 and first rings 3 can thus be used in different types of machines or machines from different manufacturers.

For this purpose, the mounting device 20 has two receiving plate 21, which are mounted on a variable-length column 22. Due to the length variability of the column 22 sleeve-shaped screen structures 2 can be provided with different pressure width b1 with first rings 3. For mounting the first rings 3 in the sleeve-shaped screen structure 2, the two first rings 3 are inserted into the receiving plate 21 of the mounting device 20. A respective receiving plate 21 preferably has three clamping elements 23. By the actuation thereof, a respective first ring can be clamped to the receiving plate 21. The clamping elements 23 may be designed as clamping disks 8 - as described above.

In FIG. 6 a washing device 30 is shown for washing rotary screen printing screens 1 after their use. The washing device 30 has for this purpose at least one receiving plate 31, in which a unit of sleeve-shaped screen structure 2 and first rings 3 can be hung. By means of preferably three clamping elements 33 in the receiving plate 31, a first ring 3 fixedly connected to the receiving plate 31 and the unit of sleeve-shaped screen structure 2 and first rings 3 are fixed in the washing device 30. To wash out the sleeve-shaped screen structure 2, the washing device 30 has two nozzle strips 34, one of the nozzle strips 34 acting from the inside and the other nozzle strip 34 from the outside to the sleeve-shaped screen structure 2. To ensure complete cleaning of the sleeve-shaped screen structure 2, the washing device 30 has a device 32 for rotating the unit of sleeve-shaped screen structure 2 and first rings 3. The nozzle strips 34 can remain so unmoved and act on the entire peripheral surface of the sleeve-shaped screen structure 2. The clamping elements 33 can be designed as clamping disks 8 - as described above.

Through the design and use of the rotary screen printing screens 1 with uniformly shaped interfaces through the first rings 3 and uniformly designed clamping elements 5 over the entire process of screen printing, comprising prepress (mounting the screen 2), pressing (picking up the screen 2 in the printing unit) and postpress ( Cleaning the screen 2) the machine operator is offered a particularly easy-to-handle system.
The use of rotary screen printing screens 1 with uniformly designed interfaces of first rings 3 and uniformly shaped clamping elements 5 in the prepress can also extend to devices for round coating, for round exposure and for round development. Here as well an easy handling can be achieved:

In Fig. 7a and b a coating device 40 and an exposure device 50 are shown, which have an analogous structure to the devices according to FIG Fig. 5 and 6 exhibit. With the device 40 according to Fig. 7a For example, in the first step, a photosensitive coating is applied to a screen structure 2 with the device 50 according to Fig. 7b In a second step, the coating is exposed, ie imaged and in a third step the exposed coating is developed. For development, a device with a structure similar to the washing device 30 can be used.

As in Fig. 7a represented, the coating device 40 according to the invention comprises two receiving plates 41, which are each equipped with clamping elements 43. These each receive an adapter ring 45. Between the two adapter rings 45 a screen structure 2 is held. A round coating ring 46 filled with coating liquid can be moved along the screen structure 2 in the direction of the arrow, with a coating being applied.

As in Fig. 7b illustrated, the exposure device 50, which is designed as a CtP imagesetter, erfmdungsgemäß two receiving plate 41, which are each equipped with clamping elements 43. As a result, a screen structure 2 to be exposed is held. During the exposure by a laser 42, z. a UV laser, the screen structure is rotated by means of a rotary drive 44.

For stripping, a device similar to the washing device 30 can be used, wherein a suitable de-coating agent must be used. Subsequently, a screen structure 2 can be recoated and exposed.
