Definitions

  • 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 distance rods 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 hardened, 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 Get 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 invention initially relates to a method for producing a screen printing cylinder, the one flexible held between two end rings and has a permeable jacket for liquids or pasty masses.
  • the jacket is made by moving the end rings stretched apart.
  • the inside of the coat is covered by a only on one side of the cylinder longitudinal axis of the screen printing cylinder and at least approximately over the entire length of the screen printing cylinder extending system in a parallel to the cylinder axis lying position pressed.
  • the system takes during the rotation of the screen printing cylinder always a fixed angular position.
  • At the method of the invention is also the sampling of the screen printing cylinder from the outside when rotating it only in the area of the system carried out.
  • the method according to the invention allows 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, that is, on the outer peripheral surface of the screen printing cylinder.
  • the jacket can be patterned in such a way that a masking liquid is applied directly to this according to the pattern becomes.
  • a masking liquid can be a curable liquid, a wax, a Metal alloy, and the like.
  • Sampling of the jacket can be preferred in the area of the system done with a processing station that is moved parallel to the cylinder axis becomes.
  • the processing station is therefore always opposite the system, so that they only sample the screen printing cylinder in the area of the system can if this turns.
  • the sampling area i.e. the area in which the sampling station can work is on the area of the facility. Of course, this does not apply to the pattern itself extends over the entire circumferential surface of the screen printing cylinder.
  • a gauze can be used as the jacket, 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 invention also relates to a device for producing a Screen printing cylinder, the device first being a storage device for storing the screen printing cylinder, such that it is around his Longitudinal cylinder axis is rotatable.

  • a processing station belonging to the device for sampling the screen printing cylinder from the outside is opposite the system positioned.
  • the storage facility, the tensioning facility, the system and the processing station can all be on one bed Processing machine are located, which is approximately lathe-like.
  • the screen printing cylinder can be made by the system provided according to the invention for sampling purposes in a simple manner on the machine put on and remove from this again, so that the processing step the sampling overall considerably simplified.
  • the system is preferably as about its longitudinal axis rotatable shaft is formed, which is firmly positioned in its angular position and rests via a gear on the axis on which the end rings sit and which is rotated to rotate the screen printing cylinder. In this respect results a compact unit.
  • the processing station is preferably seated 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.
