Definitions

  • the invention relates to a doctor device with at least one doctor blade that can be received on a doctor holder.
  • doctor blade can be inserted loosely into an associated insertion slot of the doctor holder.
  • the inside width of the insertion slot which preferably extends over the entire length of the doctor blade holder, can have an excess of about 3 / 100mm to 4 / 100mm compared to the thickness of the associated doctor blade. This measure results in a reliable doctor blade support despite the desired degree of freedom of expansion.
  • the insertion slot can advantageously be delimited by a bar that can be attached to the doctor holder provided with a step-shaped recess. This measure enables simple production of the insertion slot.
  • a further advantageous measure can be that the sealing jaws are arranged in a flexible manner in the longitudinal direction of the doctor blades, preferably being able to be pressed resiliently against the doctor blades. This ensures that in the event of expansion of the doctor blades, the sealing jaws can deflect, which also prevents ripple of the doctor blades in this case.
  • the short inking unit on which FIG. 1 is based consists of a rubberized applicator roller 2 which interacts with a plate cylinder 1 and is supplied with ink by an anilox roller 3 and with dampening solution 4 by a dampening unit 4.
  • the circumference of the anilox roller 3, which can have a ceramic cover, is provided with cups 5 indicated in an enlarged manner and webs 6 delimiting them.
  • the cells 5 are filled with paint.
  • the webs 6 are scraped off.
  • a chamber doctor blade designated as a whole in FIG. 1 this comprises a bar-shaped doctor holder 9 which is accommodated on supports 8 fixed to the frame and on which two doctor blades 11, 12 which are offset with respect to one another in the direction of rotation of the anilox roller are accommodated. These limit an ink receiving chamber 13, which is supplied with offset ink by means of a pump 16.
  • the other doctor blade 12 acts as a closing doctor. In the exemplary embodiment shown, both doctor blades are arranged with a negative angle of attack.
  • This is provided with squeegee blades 11, 12, each of which has insertion slots 15 that extend over its entire length.
  • the doctor holder 9 is in the region of its flanks, each with a step-shaped Provide recess, which is closed by a bar 10 attached to the doctor holder 9 so that the groove-shaped insertion slot 15 results.
  • the clear width of the insertion slots 15 has an excess of approximately 3 / 100mm to 4 / 100mm compared to the thickness of the doctor blade assigned in each case.
  • Doctor blades 11, 12 also extend over the entire length of the doctor holder 9.
  • the ink-receiving chamber 3 is delimited by sealing jaws 43 resting on the circumference of the anilox roller 3 and on the end faces of the doctor blades 11, 12.
  • These are formed by their side edges in corresponding, 46 provided on the doctor holder 9 guides 46 insertable plates.
  • the clear width of the guides 46 has so much excess in the longitudinal direction of the doctor blades 11, 12 compared to the thickness of the sealing jaws 43 that a corresponding evasion of the sealing jaws 43 is possible in the event of an expansion of the doctor blades 11, 12. These are pressed resiliently onto the end faces of the doctor blades 11, 12.
  • the sealing jaws 43 are gripped in the area of their abutment on the doctor blade end faces by finger-shaped abutments 44, which are resiliently supported in the longitudinal direction of the doctor blades 11, 12 on the doctor holder 9, as indicated at 45.
