Definitions

  • the invention relates to an anilox roller for an application work, with a well engraving, 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 medium 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 application rollers, the width of the engraving in the ceramic surface also being a further parameter.
  • US-A-2 380 047 describes an application method in which an anilox roller with rectangular cells is used, which are arranged at an angle of 0 ° or 90 ° to the axis of rotation of the roller.
  • Coating systems for web-shaped materials also work with anilox rollers in their application plants.
  • the layer thickness of the application medium to be applied is, for example, ten to thirty times greater than in printing machines with anilox roller inking, most of the application units in coating systems work with anilox rollers which are provided with a hash engraving.
  • the dispensing agent is metered in by means of the elongated cells with the properties of the known, largely linear square cells, but with the avoidance of disadvantageous edge thickenings for the coating to be produced on a paper base or similar base material.
  • the ratio of the length L of the wells 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 over the application roller in contact with the surface of the webs ensures a perfect wiping process, namely 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 that comes into engagement with the squeegee is made of hard ceramic, just like 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 engraving roughly corresponds 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 displacement of 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 parquet engraving pattern is only the ratio of the length and width of the cells, i.e. their elongated shape.
