Fig. 4a, 4b ) is applied to the doctor application surface 43. A rotation of the squeegee 30 or swapping the right and left sides and the front and back is thus not possible, so When exchanging a doctor blade, the doctor blade to be inserted is always inserted in its correct position and orientation.
  • the doctoring chamber body 40 On its rear side 46, the doctoring chamber body 40 has a ball joint guide 47, in which a ball joint, which is attached to a printing cylinder or other pressing means, is inserted and held.
  • a ball joint which is attached to a printing cylinder or other pressing means.
  • Fig. 6 is shown in an enlarged schematic cross-sectional view of the contact area of a doctor blade 30 and the anilox roller 5.
  • the anilox roller 5 is used according to the in Fig. 6 turned arrow turned counterclockwise.
  • the doctor blade 30 lies with its back on the doctor blade application surface 44 of the flank body 42 against slipping on and is clamped or fastened with appropriate fasteners.
  • the flank body 42 terminates at its outer end in the region of the back upper edge 32 at the end of the back 36 of the doctor blade 30, so that when a glue chamber with the doctor blade 30 to the anilox roller 5, the end of the doctor blade 30 is not bent, the doctor blade 30 against the anilox roller 5 is pressed with a predetermined pressure or a predetermined force.
  • the doctoring lip 33 of the doctor blade 30 is in touching contact with the surface of the anilox roller 5, so that along the doctoring lip 33 a linear contact area of the doctor blade 30 or the doctoring lip 33 and the anilox roller 5 is formed perpendicular to the plane of the drawing.
  • a squeegee angle between 30 ° to 35 °, in particular of 32.5 °, advantageous because at such a squeegee angle ⁇ , the variance of the recorded glue amount (per time) at a predetermined Rakelan horr and different production speeds of a machine (between 5,000 to 25,000 cigarettes per minute) is minimized.
  • Fig. 7 schematically the arrangement of a glue chamber 3 on an anilox roller 5 is shown.
  • the glue chamber 3 has the glue chamber body 40 (cf. Fig. 5a ), which is bounded on both sides by side parts 48, 49, which also delimit the anilox roller 5 laterally.
  • the anilox roller 5 is driven in rotation about its axis of rotation 55. Under rotation removes the anilox roller 5 from a glue stock in the glue chamber 3 glue, wherein at the outlet of the glue-filled cup excess glue in the linear contact region of the doctor blade with the surface of the anilox roller (see. Fig. 6 ) is doctored off on the exit side.
  • the side parts 48, 49 have recesses 51, in which the retaining pins 52 engage laterally, the retaining pins 52 laterally, e.g. are attached to the housing in which the anilox roller 5 and the glue chamber 3 are arranged.
  • the recesses 51 on the side parts 48, 49 are arranged such that the central axis of the retaining pins 52 collinear in the contact area or in the line of contact of the doctor blade with the surface of the anilox roller 5, so that the glue chamber 3 about the pivot axis 70 pivotable is.
  • the pivot axis 70 is collinear with the linear contact area between the doctor blade and the surface of the anilox roller 5.
  • Fig. 8 schematically a perspective view of the doctor chamber 3 is shown, for reasons of better representability of the marking of the right side part (see. Fig. 7 , Reference numeral 48) has been omitted.
  • the doctor blade 30 is arranged with its rectilinear doctoring lip 33 on the doctor blade application surface 44 of the flank body 42.
  • a doctor blade 60 which has a non-linear doctor blade 63, is arranged on the doctor application surface 43 of the flank body 41.
  • the non-linear doctor blade 63 has a vertex 64 in its center.
  • the contact surface 43 corresponding to the doctor 60 is also formed with a kink (not shown here).
  • a clamping body 62 is mounted between the flank members 41, 42 for fastening the doctor blades 30, 60, the corresponding holes for the supply and forms the removal of glue from the glue distribution chamber formed in cooperation with the anilox roller.
