Definitions

  • the invention relates to a roller with a surface consisting of hydrophilic and oleophilic partial surfaces and a method for producing such a surface.
  • the invention has for its object to provide a surface for an inking roller with a surface that has hydrophilic and oleophilic areas and a method for producing such a roller.
  • the object is achieved with the method steps of the characterizing part of claim 1 and the features of the characterizing part of claim 2.
  • roller is created in which the small oleophilic surfaces are made of an oleophilic metal can exist and after flushing or chemical ablation can easily be applied again to the target deepening, e.g. B. by applying material by an electro-chemical process or vice versa, if the load-bearing hydrophilic areas that are in contact with the doctor blades are more worn, the deeper oleophilic areas.
  • the oleophilic areas are electrochemically removed until the desired distance from the oleophilic to the hydrophilic surface of immediately adjacent areas is reached again. The life of the roller can be extended further.
  • the oleophilic surface 4 of the metal layer 3 is provided with a number of depressions 6 which are so deep that they either lead to the outer surface 1 or end within the thickness of the oleophilic metal layer 3.
  • These depressions 6 can have any cross section and can be produced in a wide variety of ways, for. B. by laser, turning, rolling, engraving, etc.
  • the recesses 6 can, for. B. as one or multi-stage helical grooves 7 with z. B. a slope of 1 mm, a width of z. B. 0.5 mm and 0.15 mm depth.
  • the grooves 7 can be in the same direction but also in opposite directions to one another.
  • the recesses 6 can also have a wide variety of cross sections, z. B. be round, diamond-shaped or elongated.
  • the indentations 6 After the indentations 6 have been introduced into the oleophilic metal layer 3, at least the indentations 6 are completely filled with a largely wear-resistant and hydrophilic material 8, e.g. B. by means of the flame spraying process.
  • a largely wear-resistant and hydrophilic material 8 e.g. B. by means of the flame spraying process.
  • the largely abrasion-resistant material 8 consists, for. B. made of ceramic (CR2 O3). Since the targeted filling of the depressions 6 is not possible, it cannot be avoided that the entire surface 4 of the oleophilic metal layer 3 is covered with at least one thin layer 9 of the material 8. This layer 9 of material 8 is now removed so far, e.g. B. ground that the material of the metal layer 3 - interrupted by the fillings 10 of the recesses 6 - is completely exposed. The outer surfaces 11, 12 of material 8 and fillings 10 of the depressions 6 are now at the same level. Now the outer surfaces 11 of the entire metal layer 8 are optionally placed lower (FIG. 2) and thus become the final oleophilic transport surface 13, so that they are e.g. B. 0.03 mm below the outer surface 12 of the ground fillings 15 with a hydrophilic transport surface 14. This can be done in different ways, e.g. B. by etching or electro-chemical removal.
