Definitions

  • a method and an apparatus for producing a screen printing cylinder are already known from FR-A-1 552 436 and DE-AS 1 671 499. It is about the production of a two-layer screen printing or rotary screen printing cylinder for textile printing.
  • the screen printing cylinder too can be equipped with end rings, can have a structure as it for example, is known from British Patent 1,050,649. There is a relatively coarse-mesh cylinder from a relatively fine-mesh cylinder surround.
  • the screen printing cylinder held on the front on bundles, which are rotatably attached to a cross member are. Presses against the outer surface of the screen printing cylinder from the inside a backup roller which extends in the longitudinal direction of the screen printing cylinder.
  • a pinch roller Extends outside the screen printing cylinder and parallel to the backup roller a pinch roller, which is at a distance from the backup roller.
  • a pinch roller Extends outside the screen printing cylinder and parallel to the backup roller.
  • the gap between the support roller and the squeeze roller is tangential to the screen printing cylinder a die can be passed through, the plate-shaped and with is provided with a pattern. Pattern is determined by this matrix Masking material applied to the surface of the screen printing cylinder to to close this area.
  • the screen printing cylinder rotates, which is rotatably mounted on the cross member on the bundles, when the die is transported through the gap between the pinch roller and back-up roller.
  • the screen printing cylinder is one in which the inner cylinder relatively firm and the outer cylinder is relatively flexible, for example made of nylon consists.
  • gauze Screen printing cylinder for use.
  • Gauze can be nylon or plastic sieves with different mesh sizes.
  • the gauze is on two stable and for example metallic End rings with a certain diameter glued on. However, they would be thus produced screen printing cylinder completely unstable, so that between the two or possibly three spacer rods are arranged on both end rings, to keep the end rings at a distance.
  • These spacer bars are exclusive for transporting and storing and if necessary when developing the Screen printing cylinder used. For coating, sampling and printing these spacer bars are removed again, as with these steps the fixation of the screen printing cylinder or its end rings from the respective Machines is accomplished.
  • Such a screen printing cylinder is horizontal on one of the machines mentioned arranged, the gauze constricts in the middle. With others Words, the outside diameter of the screen printing cylinder increases Middle down. This can be done by stretching the gauze lengthways Screen printing cylinders can only be partially compensated for by the end rings be moved apart.
  • the plexiglass shell and film are removed from the screen printing cylinder removed and the screen printing cylinder itself from the exposure machine away. Then the exposed photosensitive layer developed, dried, possibly retouched and cured, so that the screen printing cylinder is then ready to print.
  • the conventional method is relatively cumbersome because u. a. the plexiglass bowls must be used to the cylinder peripheral wall when patterning or exposing via film in a radial position to keep the radial position of the peripheral wall in the area of Squeegee corresponds to later printing. Otherwise they will be distorted Received samples.
  • the invention has for its object a method of the aforementioned Kind in such a way that the handling of the screen printing cylinder is improved especially in the patterning. There should also be one suitable device created for performing this method become.
  • the method according to the invention permits a considerably simpler one Handling the screen printing cylinder when sampling, since this is only needs to be placed on the sampling device without it is necessary to surround it with additional pressure elements or inflate a hose roller lying in it.
  • the touchdown and Losing weight on the device or from the device thus takes place relatively easy.
  • the system and the sample in Area of this system ensures that always flawless and undistorted Also receive prints when printing on tiles or ceramics if the printing area or squeegee is there during the printing process where the system was previously located.
  • a Roll used, the longitudinal axis of which is parallel to the cylinder longitudinal axis. Since the roller itself can rotate freely about its longitudinal axis, Rotation of the screen printing cylinder about its cylinder axis and runs on the inner peripheral surface of the screen printing cylinder. By this rolling process is avoided that additional tensions in the Circumferential wall of the screen printing cylinder are transferred, resulting in a leads to even better print quality.
  • the jacket of the screen printing cylinder can be used in many different ways be sampled.
  • the sampling process always takes place from the outside, thus on the outer peripheral surface of the screen printing cylinder.
  • the sampling of the jacket can be carried out that a masking liquid is applied directly to this according to the pattern becomes.
  • a masking liquid can be a curable liquid, wax, a Metal alloy, and the like.
  • a gauze is used as the coat, the pores or Has openings with a certain mesh size.
  • the gauze can also consist of nylon or another plastic. It's relatively flexible in order not to damage tiles or ceramics in particular when printing and so as not to harm yourself.
  • the machine end rings, the clamping device, the system and the processing station can all be on one bed of a processing machine are located, which is approximately lathe-shaped.
  • the screen printing cylinder can be easily applied to the machine for the purpose of sampling put on and take it off again, so that the processing step the sampling overall considerably simplified.
  • the system is preferably as about its longitudinal axis rotatable shaft which is fixedly positioned in its angular position and rests via a gear on the axis on which the end rings are seated and which is rotated to rotate the screen printing cylinder. In this respect it follows a compact unit.
  • the processing station sits on a carriage of the processing machine, the carriage in turn on a guide rail is slidable, which rests on the machine bed and extends parallel to the longitudinal direction of the shaft on which the screen printing cylinder has been put on.
  • the processing station can be used as Spray head for spraying liquids or other viscous media be trained.
  • the spray head can also be designed that it is suitable for spraying liquid metal alloys, for example for spraying out woody metal. It can move other processing units behind an ejection opening have, such as a heat source for hardening the sprayed liquid by applying heat.
  • the processing station can also have an exposure head have to light-sensitive layers for example with focused To be able to expose radiation or around other layers with more focused To be able to remove radiation.
  • focused radiation it can be focused laser radiation, for example.
