Definitions

  • the invention relates to a method for producing an anilox roller for an inking unit of an offset rotary printing press, which has webs made of a wear-resistant, hard material and cells with a surface made of an ink-accepting material.
  • an anilox roller is known in which the roller core carries a wear-resistant ceramic or metal layer. This layer is engraved to accommodate a layer of a color-accepting, water-repellent material. The ink-accepting layer, which was initially applied in excess, is removed to such an extent that the upper sides of the webs of the underlying wear-resistant layer are exposed. The cells are also introduced into this layer.
  • the wear-resistant hard layer is engraved using a laser beam and is therefore comparatively expensive.
  • an anilox roller 1 has a roller core 2, the diameter of which is a few tenths of a millimeter smaller than the final diameter of the anilox roller 1.
  • the roller core 2 is made of steel in the exemplary embodiment.
  • the roller core 2 is coated with a layer 3 consisting of ink-accepting material.
  • Layer 3 can e.g. are made of copper. This material repels water and at the same time has a high affinity for color.
  • nickel, asphalt or a suitable plastic, such as Rilsan it is also possible to use nickel, asphalt or a suitable plastic, such as Rilsan.
  • the layer 3 can be sprayed on or vapor deposited or, depending on the material used, applied galvanically or by chemical deposition.
  • grooves 4 are advantageously worked into the ink-accepting layer 3 by partially removing this layer 3, except for the roller core 2.
  • the grooves 4 are, as indicated in Fig. 3, arranged obliquely to the axis of the anilox roller 1 in the embodiment.
  • the incorporation of the grooves 4 can be done by a simple engraving process, e.g. Etching.
  • Another possibility of creating the grooves 4 is to cover the surface of the roller core 2 at the locations provided for the grooves 4 before the ink-accepting layer 3 is applied.
  • the covering can be carried out by means of lacquer strips which are removed after the layer 3 has been applied.
  • the grooves 4 are made of a hard, wear-resistant material existing layer 6 introduced, in such a way that an anchoring is formed on the one hand with the ink-accepting layer 3, and on the other hand, if the grooves on the roller core go through, with this as well.
  • Chromium dioxide or, for example, can be used as the material for forming this hard, wear-resistant layer 6 Find aluminum oxide.
  • This layer 6 can be introduced using the plasma spraying method.
  • the layer 6 initially covers at least partially the peripheral surface of the ink-accepting layer 3.
  • a subsequent surface treatment is expedient in which the hard layer 6 above the ink-accepting layer 3 is removed.
  • This processing step is based on FIG. 5, which shows a surface 7 ground and polished on the circumference. The surface 7 is smoothed so that the layer 6 only fills the grooves 4 in the ink-accepting layer 3 and forms wear-resistant webs 8.
  • the thickness of the ink-accepting layer 3 is at least the depth of the wells 9.
  • the depth of the wells 9 is of the order of approximately 20 ⁇ m.
  • the width of the grooves 4 and thus the webs 8 is approximately in the order of the depth of the wells 9.
  • a major advantage of this procedure is that the load-bearing, wear-resistant layer 6 does not have to be engraved. Since the engraving always takes place in the ink-accepting layer 3, which is relatively soft, it is comparatively simple and enables inexpensive production.
  • the surface of the anilox roller 1 has wear-resistant webs 8 which run obliquely to its axis and surround it on the circumferential side.
  • the webs 8 are embedded in the layer 3 of ink-accepting, water-repellent material and are arranged at equal distances from one another.
  • the cups 9 are also engraved at regular intervals between the webs 8 in the ink-accepting layer 3.
  • the wells 9 are bordered on the one hand by the wear-resistant webs 8 and on the other hand by webs 10 which are formed from the ink-accepting layer 3.
  • the webs 10 can also be made of wear-resistant material in the same way as the webs 8. This requires incorporation of the grooves 4 in a cross-diagonal arrangement on the anilox roller 1, as described above.
  • the grooves for forming webs 11 on the anilox roller 1 can also be arranged hexagonally. Between the webs 11, well-shaped cells 12 are engraved into the ink-accepting layer 3.
