To be a good and To ensure a tight fit of the sealing pieces in their recordings each bolt on the swivel pin by a spring towards the Be pressed against the front of the doctor blade carrier.
  • seats are in the end faces of the doctor blade carrier recesses forming the sealing pieces are incorporated.
  • intermediate plates are provided between the Outside of the sealing pieces and the bars inserted intermediate plates.
  • These intermediate plates prevent the rubber gaskets or other elastomeric Material can be damaged by the bolts when they are pivoted.
  • the intermediate plates expediently have end faces which are in the same way are designed like the end faces of the sealing pieces.
  • the sealing pieces can consist of shaped pieces with mutually parallel sides, those with roof-shaped bevels on the back of the doctor blades and between them with a bowl-shaped recess on the inking roller issue.
  • the doctor device consists of a strip-shaped doctor knife carrier 1, the is provided with a central longitudinal color groove 2.
  • the doctor knife carrier 1 is provided on both sides of the color channel 2 with roof-shaped inclined surfaces 3 which clamps 4 are held, which fix the doctor blade 12 in the usual way.

  • the sealing pieces 7 consist of fittings with mutually parallel sides 8.
  • At their Sides opposite to the sections embedded in the recesses 6, have the sealing pieces 7 roof-shaped beveled inclined surfaces 9 and between them a bowl-shaped recess 10, the radius of curvature corresponds to the radius of the inking roller, not shown.
  • With their roof-shaped beveled surfaces 9 are the sealing pieces on the undersides of the doctor blade 12 attached by the clamping pieces 4.
  • the doctor blade carrier 1 carries one with a head on one side of each end face 13 provided bolt on which the consisting of an approximately trapezoidal plate Bolt 14 is pivotally mounted in a bore. On the bolt is between the end face 5 and the bolt 8 held a ring 14 forming a support. Between the head 13 of the bolt and the bolt 14 are relatively soft Disc springs are inserted, which act resiliently on the bolt 14 in the direction of the end face 5. On the opposite sides of the end faces 5 is in each end face another bolt provided with a head 16 is screwed in. That bolt has a shaft part 17 between the end face 5 and the head 16, which like the ring 14 forms a support for the intermediate plate 18.
