Definitions

  • the invention relates to an ink knife arrangement for the ink fountain of a web printing press with resiliently arranged, resilient tongues which can be individually adjusted in their distance from a roller immersed in the ink fountain by means of adjusting devices.
  • a color knife arrangement which has juxtaposed slats consisting of thin elastic plates, which are fastened together on a receiving part, which in turn is attached to a paint box beam via a screw connection.
  • the disadvantage of this color knife arrangement is that the lamellae are each attached using only one screw and that a round hole is provided in the lamellae for this screw.
  • This type of attachment means that the initial distance between the slats and the roller is fixed and the slats can only be adjusted to a limited extent to compensate for wear.
  • EP-A-0 344 546 shows ink knife tongues which can be displaced radially to the ink fountain roller for the purpose of ink gap adjustment with adjusting units. With this setting, this device is also unconsciously used to compensate for any wear on the tongues.
  • metering elements are individually longitudinally displaceable tangentially on an ink fountain roller.
  • a continuous doctor blade is longitudinally displaceable to a duct roller for the purpose of rough adjustment of the gap.
  • the squeegee is mounted in the sliding direction.
  • the object of the invention is to provide a color knife arrangement in which the wear of the color knife can be compensated well and thus its useful life can be significantly increased.
  • FIG. 1 shows a color knife arrangement in an embodiment according to the invention.
  • a plurality of tongues 1 are arranged next to one another and fastened to a carrier element 4 by means of screws 2 and 3.
  • a washer 41 serves as an assembly aid to prevent the tongues 1 from pivoting when the screws 2 and 3 are tightened.
  • the elements 1 to 4 and 41 together form the ink knife 5.
  • the ink knife 5 is fastened to a paint box 7 by means of screws 6.
  • each tongue 1 is designed as a resilient, rectangular plate.
  • it has an elongated hole 8 made in the longitudinal direction of the tongue 1 in the center thereof.
  • the width of the elongated hole 8 is selected so that the screws 2 and 3 can be guided through the elongated hole without forcing a certain lateral orientation of the tongue 1.
  • the length of the elongated hole 8 is shorter than the distance between the screw 3 and the front edge of the carrier element 4, so that the elongated hole 8 always remains covered by the carrier element 4 even when the tongue 1 is readjusted.
  • the tongue 1 has on its two longitudinal sides two recesses 9 and 10 of equal length, which are arranged essentially in the same area as the elongated hole 8.
  • Such a recess 9 of a tongue and such a recess 10 of an adjacent tongue together form an elongated hole through which one of the screws 6 for fastening the ink knife 5 on the ink fountain 7 is passed.
  • FIG. 3 shows the color knife arrangement according to the invention from FIG. 1 in a sectional view. From this representation it can be seen that the ink knife 5 is in a manner known per se against a roller 11 which is immersed in the ink fountain 7. To adjust the thickness of the ink film on the roller 11 and to compensate for the wear of the front edge 12 of the tongue 1, a device is shown symbolically as a simple screw 13, by means of which a distance of the front edge 12 from the roller 11 is set.
  • the color knife 5 is removed.
  • the tongues 1 are then set up after loosening the screws 2 and 3 so that the front edges 12 of the tongues 1 are again in an initial position.
  • the present invention has the advantage that the tongues 1 can be readjusted several times when it is no longer possible to adjust them using the adjusting device 13. As a result, these relatively expensive wear parts can be used for a significantly longer time, which corresponds to a significant contribution to lowering the maintenance costs.
  • longitudinal slots can also be provided, which extend to the end of each tongue 1 facing away from the roller 11.
