Definitions

  • the innovation relates to the engraving of an application roller, specifically an anilox roller for an application unit in a coating machine according to the preamble of claim 1.
  • Application units of the type of interest here can only meet the high requirements for the uniformity of the coating if layers of the application medium of the same thickness are ensured at all times over the entire web width, in particular also the edge regions.
  • the surface of the application roller which is provided with a matrix of cells for metering the application agent and which is in engagement with a doctor blade, forms very narrow webs between the cells and specifies a very small web-cell ratio.
  • the shape and size of the cups in the ceramic layer inevitably determine the volume of the metering cups in the case of applicator rolls, and as a further one Parameters also include the web width of the engraving in the ceramic surface.
  • Coating systems for web-shaped materials also work with anilox rollers in their application plants. But since the layer thickness of the application agent to be applied e.g. is ten to thirty times larger than in printing presses with anilox roller inking, most of the coating units work with anilox rollers that are engraved with hash marks.
  • Engravings of this type transmit a maximum of application funds because the "wetness" is only limited by two webs.
  • the other reason for the popularity of hash rollers in coating machines is the good emptying of the "well”.
  • the engraving consists of elongated cups 1 which are flattened in cross section and are delimited by longitudinal webs 2 and transverse webs 3.
  • the longitudinal webs 2 have a straight inner edge 4 towards the wells 1, while the transverse webs 3 delimit the wells with an arched inner edge 5.
  • the entirety of the cells 1 arranged in rows and rows In this respect, it is fundamentally to be compared with a hash engraving, the line engraving of which, however, is delimited at a distance from one another by the transverse webs 3, with adjacent lines each having crossbar arrangements offset to a gap.
  • the cups 1 are arched perpendicular to the direction of the quasi-linear structure, as shown in particular in FIG. 2; their cross section can correspond, for example, to a segment of a circle.
  • the ratio of the length L of the cells to their width D can vary between 2: 1 to 20: 1.
  • the width of the webs 2, 3 is dimensioned such that the doctor blade running in contact with the surface of the webs ensures a perfect wiping process over the entire width of the application roller.
  • the direction of the engraving, ie that of the longitudinal and transverse webs 2, 3, is at an angle, preferably at an angle of 45 °, to the doctor blade or to the axis of rotation of the roller.
  • the surface of the webs which comes into engagement with the squeegee is made of hard ceramic, just as the entire roller shell is made of ceramic at least over the depth of the cups 1.
  • the inner surface of the cup 1 dosing the application agent is advantageously metal-coated, preferably copper-coated.
  • the new engraving corresponds approximately to the pattern of masonry with "bricks” rounded off along the narrow sides, while the "mortar” between the masonry is formed by the longitudinal and transverse webs 2, 3.
  • the engraving pattern is also comparable to a known way of laying parquet.
  • the crossbars 3 do not have to each in such a way between two adjacent, separated by a longitudinal web 2 well arrangement at a gap to each other, which corresponds to the offset half the length of a well, other displacements are also possible, as well as the series arrangement of the transverse webs 3 in a row behind the entire width of the application roller.
  • What is essential in the new parquet engraving pattern is the ratio of the length and width of the cells, i.e. their elongated shape.
