Definitions

  • the invention relates to a method for manufacturing an anilox roller for an inking unit of an offset rotary printing press, the bridges from one wear-resistant, hard material and cell with a surface of an ink-accepting Has material.
  • a coating consisting of hard ceramic is applied to a steel core, which is then engraved and provided with a color-friendly coating.
  • the hard ceramic coating is also engraved using a laser beam.
  • the US patent 47 73 143 discloses according to claim 19 and Figures 1 and 2 a manufacturing method of an anilox roller, in which wells are engraved in an oleophilic layer of the roller surface, then a spiral groove is worked out of this layer, then this groove a hard Material is filled so that a spiral layer is formed, which runs flat with or slightly raised over the oleophilic layer of the anilox roller. Both the oleophilic surface and the hard spiral rail can then be finished.
  • the disadvantage here is that the material filled into the groove can make adjacent cells usable, which in turn have to be reworked.
  • an anilox roller 1 a roll core 2, the diameter of some Tenths of a millimeter smaller than the final diameter the anilox roller 1.
  • the roller core 2 is in Embodiment made of steel.
  • the roll core 2 is made with an ink-accepting material existing layer 3 coated.
  • Layer 3 can e.g. are made of copper. This material repels water and at the same time has a high Affinity for color. Instead of copper there is also Use of nickel, asphalt or a suitable one Plastic, such as nylon 11, possible.
  • the Layer 3 can be sprayed on or evaporated on depending on the material used, galvanically, or applied by chemical deposition become.
  • Fig. 2 are in the ink-accepting layer 3 advantageously by partially removing this layer 3 up to the roller core 2 grooves 4 incorporated.
  • the grooves 4 are, as indicated in Fig. 3 is, obliquely to the axis in the exemplary embodiment the anilox roller 1 arranged to run.
  • the Incorporation of the grooves 4 can be done by a simple Engraving processes, e.g. Etching.
  • Another way to create the grooves 4 is the surface of the roll core 2 at the locations provided for the grooves 4 are, before applying the ink-accepting Cover layer 3.
  • the cover can by means of lacquer strips, which are made after application Layer 3 can be removed.
  • a hard, wear-resistant material existing layer 6 introduced in such a way that anchoring formed on the one hand with the ink-accepting layer 3 on the other hand, if the grooves on the Go through the roller core, also with this.
  • Material to form this hard, wear-resistant Layer 6 can e.g. Chromium dioxide or Find aluminum oxide.
  • the bringing in This layer 6 can be plasma sprayed respectively.
  • Layer 6 initially covers as a continuous layer the peripheral surface of the ink-accepting layer 3. To achieve a flat, even surface of the anilox roller 1 is a subsequent surface treatment sensible, in which the hard layer 6 above the ink-accepting layer 3 is removed.
  • This Processing step is based on Fig. 5, the a surface that is ground and polished on the circumference 7 shows. The surface 7 is smoothed that the layer 6 only the grooves 4 in the ink-accepting layer 3 fills and wear-resistant Forms webs 8.
  • the thickness of the ink-accepting layer 3 exceeds the depth of the cells 9.
  • the depth of the cells 9 is of the order of magnitude of approx. 20 ⁇ .
  • the width of the grooves 4 and thus the Web 8 is approximately in the order of depth the well 9.
  • a major advantage of this procedure is that the load-bearing, wear-resistant Layer 6 does not have to be engraved. Because the engraving always takes place in the ink-accepting layer 3, which is relatively soft, it turns out comparatively simple and allows an inexpensive Production.
  • the webs 8 are in layer 3 of ink-accepting, water-repellent Material embedded and in uniform Spaced from each other. Between the webs 8 are in the ink-accepting Layer 3 also at regular intervals the wells 9 are engraved. The wells 9 are on the one hand through the wear-resistant webs 8 and on the other hand by webs 10, which from the ink-accepting Layer 3 are formed, bordered. However, the webs 10 can also be made of wear-resistant Material in the same way as that Bars 8 are made. This requires an induction the grooves 4 as described in above Way in a cross-diagonal arrangement on the Anilox roller 1 ahead.
  • the grooves can be Formation of webs 11 on the anilox roller 1 also be arranged hexagonally. Between the bridges 11 are shape-matched in the ink-accepting layer 3 Cup 12 engraved.
