Definitions

  • a known version of the ink fountain (US-PS 3120 802) uses a complex ink knife design, consisting of several parts, in which the last ink knife in the direction of rotation of the ink fountain roller determines the final ink layer thickness on the roller while removing the ink layer and thus reveals no possibility of how to pass through and Color runout can be prevented, which then gets into the inking unit in an uncontrolled manner.
  • this is achieved in that a thin, resilient film strip is attached to the underside of the ink knife in the region of the wiping edge and extends over and extends over the length of the wiping edge and grinds so lightly on the ink film present on the ink fountain roller that it attaches and dripping of paint on or from the ink knife is prevented and this feeds the small amount of ink running on the ink knife back to the ink film on the ink fountain roller.
  • a thin film strip 8 is attached, the attachment to the color knife 5 e.g. can be done by gluing.
  • the film strip 8 extends over the length of the ink knife 5 and thus the doctor edge 7 and projects beyond the ink knife 5 beyond the doctor edge 7.
  • the protruding part of the film strip 8 approaches the ink fountain roller 2 in its front region and rubs lightly on the ink film present on the ink fountain roller 2.
  • the film strip 8 is bent slightly so that it lies approximately tangentially to the outer surface of the ink fountain roller 2 on the ink film.
  • the material for the film strip 8 must be resilient, so that both steel and plastic can be used, a thin plastic material of approximately 0.3 mm thickness being completely sufficient for the function of the invention.
