Definitions

  • the invention relates to an inking unit with an anilox roller inking a forme cylinder, which can be inked directly or via an additional roller.
  • the plate or forme cylinder 1 to be inked is preferably in direct contact with an anilox roller 2 which, in the manner according to the invention, has a carrier layer 3 which is designed as a compressible layer, for example made of plastic.
  • This compressible, i.e. elastic carrier layer 3 is provided with a grid, i.e. with recesses for taking up color.
  • the form cylinder 1 can with a so-called. "hard printing form”.
  • the flexible carrier layer 3 to be rasterized can be designed as a thin-walled tube which is seamlessly and easily detachably attached to the roller body of the raster roller 2, which is possible, for example, using the expansion tension.
  • Another advantageous possibility of producing the elastic carrier layer 3 is that it is vulcanized or sprayed onto the anilox roller 2.
  • the diameter of the anilox roller 2 used as the application roller can be equal to or smaller than the diameter of the forme cylinder 1, the rastering being carried out seamlessly.
  • FIG. 1 it is also possible to screen the carrier layer 3 only to a limited extent, i.e. that no rastering is provided in the area of the pit 8 of the forme cylinder 1, as indicated by raster beginning 4 and raster end 5 on the anilox roller 2.
  • the anilox roller 2 is inked directly by a chamber inking unit 6.
  • a limitation of the chamber inking unit 6 can serve here as the doctor blade 7.
  • a further embodiment of the short inking unit according to the invention consists in inking the forme cylinder 10 shown in FIG. 2 by an anilox roller 11, which in turn is provided with a flexible carrier layer 12 to be rasterized, which ends are fastened in a pit 13 of the anilox roller 11 with their ends, which are not specified can be.
  • the pit 13 can also be closed by a filler 14.
  • the anilox roller 11 is inked by a metering roller 15 which is arranged thereon and which can be arranged directly in an ink pan 16 and can be doctored off by means of a doctor blade 17 for pre-metering the ink.
  • the anilox roller 11 can be scraped off in a manner according to the invention by a doctor blade 18 in such a way that the volume of the recesses or cups in the carrier layer 12 changes, the ink volume of the anilox roller 11 being correspondingly more or less strongly pressed against the doctor blade 18 is changeable in accordance with the respective color requirement that must be supplied to the plate cylinder 10.
  • an actuating mechanism indicated at 9 on the doctor blade 18, for example in the form of an eccentric is provided.
  • Another change in the volume of color in the layer is to change its thickness, for example by expanding the core.
  • the contact pressure of the doctor blade 7 indicated there can be changed, so that the depressions or cups in the screened carrier layer 3 are changed in accordance with the desired amount of ink to be transferred.
  • the arrows indicated in FIGS. 1 and 2 each show the directions of rotation of the rollers or cylinders.
  • the coloring can advantageously take place by means of the chamber inking unit 6 shown there.
  • the wells of the anilox rollers used as applicator roller with the gap not closed or with the pit not closed should be filled with a metering roller (eg 15).
  • the excess ink on the anilox roller 11 after filling the cells with the aid of the metering roller 15 is scraped off. If the pit 13 indicated in FIG. 2 is closed with the filler piece 14, the use of a chamber inking unit is also possible in this embodiment of the anilox roller 11.
  • the cell depth can be changed by deformation of a compressible layer and control of the amount of ink to be applied is thus possible.
