Definitions

  • the present invention relates to a chamber doctor blade for inking a printing cylinder, in particular an anilox roller, with an ink chamber with a lateral ink outlet opening extending over its length, the two longitudinal edges of which are each delimited by a lip-like doctor blade.
  • the chamber doctor blades that are common today are designed according to the above construction, the front doctor blade as seen in the direction of rotation of the printing cylinder serving as the closing doctor blade (for the ink outlet opening) and the subsequent further doctor blade as the actual working doctor blade (for stripping off the ink or pressing the ink into the "well") the anilox roller) is provided.
  • the quality of the print produced leaves something to be desired, which is due to the irregular filling of the grid depressions.
  • the object of the present invention was to avoid this disadvantage, which was surprisingly achieved by the measure according to the invention.
  • the object in the case of a chambered doctor blade of the type defined at the outset is the feature according to the characterizing part of claim 1.
  • Fig. 1 purely schematically, the doctor blade arrangement according to the invention in a vertical section through a chamber doctor blade, and
  • FIG. 2 shows a support structure for an additional doctor blade, for use from above in a doctor blade chamber.
  • Figure 1 of the drawing shows schematically in vertical section a chamber doctor blade 1 for inking a printing cylinder, in particular an anilox roller 2.
  • An ink chamber 3 has a lateral ink outlet opening 4 which extends essentially over its entire length.
  • the lower longitudinal edge 4 1 is delimited by a lip-shaped closing doctor 5 (sealing against the impression cylinder 2, which rotates in the direction of the arrow).
  • the upper longitudinal edge 4 ′′ of the ink outlet opening 4 is delimited by an actual working squeegee 6, which serves to strip off the ink or impress the ink into the raster images of the printing cylinder 2, for example into the “cups” of an anilox roller.
  • the inventive element now consists of an additional doctor blade 7 arranged between the two doctor blades 5 and 6, which forms a pre-doctor blade and surprisingly contributes to the optimal filling of the cells of the anilox roller.
  • the additional squeegee 7 is arranged on a support structure 7 'which is fixedly or removably attached to the chamber 3.
  • FIG. 2 of the drawing schematically shows a support structure 7 for the additional doctor blade 6, upper supports 9, 10 serving to fasten the support structure 7 'of the additional doctor blade 7 to the upper opening 8 (FIG. 1) of the chamber 3.
  • the support structure 7 ' is thus also suitable for retrofitting in existing doctor blades.

Abstract

L'invention concerne une racle de bac présentant outre les racles classiques (5, 6) qui délimitent les bords longitudinaux (4', 4'') de l'ouverture latérale de sortie d'encre (4), une racle supplémentaire (7) qui s'étend également sur la longueur de l'ouverture de sortie d'encre (4), parallèlement aux racles (5, 6), et sert ainsi de racle préalable qui assure une application optimale de l'encre.
