Definitions

  • the invention relates to an ink fountain for a printing press with an ink fountain roller forming the front boundary, an ink knife running parallel to this and perpendicular to the axis of the ink fountain roller, on this and on the ink knife adjacent side walls, each consisting of a fixed and connected to it the ink fountain roller resiliently part, the ink knife is longer than the ink fountain roller and the part lying on the ink fountain roller rests against the front side and the slope of the lower edge of the resilient part 4 corresponds to the angle caused by the installation of the ink knife 11 the ink fountain roller is created.
  • a paint box of this type is already known from DE-A No. 2437584.
  • a side wall portion connected to a fixed side wall portion by means of an elastic material is pressed onto the front of the ink fountain roller.
  • the elastically pressed side wall part is screwed to the color knife.
  • the object of the invention is to design an ink fountain of the type specified at the outset in such a way that ink cannot flow out on its sides either in the region of the ink fountain roller ends or between the side parts and the ink knife.
  • the ink fountain can be adjusted to an ink fountain roller 1 in a conventional manner from a traverse 2 running in the axial direction of the ink fountain roller 1 with an inclination towards the ink fountain roller and is delimited on both sides by side walls.
  • the ink fountain roller 1 itself gives the front (FIG. 1, right) limitation of the ink fountain 2. If necessary, a rear rear wall (not shown in more detail in FIG. 1) can also be used.
  • Each side wall consists of an outer end jaw 3, which is firmly connected to the ink fountain crossmember 2 by fastening means.
  • fastening means e.g. Cheese head screws 5, 6 used.
  • An inner end jaw 4 can be attached to the outer fixed end jaws 3 by means of studs 8, 9, 10 with nuts.
  • the side wall formed from an outer 3 and an inner connecting jaw 4 stands vertically on an ink knife 11, which is longer than the ink fountain roller 1 and thus protrudes at both ends beyond the front side A of the ink fountain roller 1.
  • the end jaws 3, 4 are held on the outer fixed end jaw 3 by means of the stud bolts 8, 9, 10, since these engage in the threaded blind holes of the inner end jaw 4 via through holes in the outer end jaw 3.
  • the inner end jaw 4 can be pressed against the front side A of the ink fountain roller 1 and stands approximately vertically on an ink knife 11 which, as can be seen best in FIG. 3, is longer than the ink fountain roller 1 and thus protrudes beyond its front side A at both ends.
  • Set screws 12, 13, 14 can be screwed into the threaded through-bores of the outer end jaw 3, which are preferably each provided with a blind hole into which compression springs can be inserted.
  • the inner end jaw 4 is pressed against the end face A of the ink fountain roller 1 by a compression spring 15 arranged in the adjusting screw 13.
  • the surface of the inner end jaw 4 resting against the front side A of the ink fountain roller 1 is preferably equipped with a wear-resistant layer which has good sliding properties.
  • a holder 16 On the outer end jaw 4, a holder 16 is fastened, which supports a compression spring 18 via a threaded pin 17, which with its lower end (FIG. 3) always holds the inner end jaw 4 with a suitable contact pressure via a T-shaped seal 7 on the ink knife 11 presses. This also ensures a permanent closure between the inner end jaw 4 and the color knife 11.
  • the contact pressure between the inner end jaw 4 and the front side A of the ink fountain roller can be adjusted with the help of the studs 8, 9, 10 against the pressure of the springs
  • the outer end jaw 3 is provided with a recess B which is able to accommodate the inner end jaw 4, so that the inner sides of the end jaws 3, 4 lie approximately in one plane.
  • the edges of the end jaws 3, 4 facing the ink knife 11 are provided with a groove in which the cross leg of the T-shaped seal 7 is arranged in such a way that an exact seal is provided over the entire width of the ink knife 11.
  • a seal between the end jaws 3, 4 is achieved in particular by the vertical leg of the seal 7.
  • the vertical leg of the seal 7 (FIG. 1) is pressed onto the end jaws 3, 4 by means of clamping strips 19, 20 (FIG. 2) by means of setscrews 21, 22, so that an exact seal is achieved.
  • a guide groove 23 is arranged in the outer end jaw 3, into which a corresponding elevation 24 of the inner end jaw 4 engages.
  • the inner end jaw 4 is preferably kept very narrow in the ink fountain roller ink knife area, end jaws, so that only this narrow area touches the ink knife 11. This has the advantage that in the event of an inclination of the color knife 1 in the longitudinal direction, no gap can arise from which the color could escape.
  • the end jaw 4 also touches the ink knife 11.
  • a vertically acting compression spring 18 was installed, which presses the end jaw 4 against the ink knife 11.
  • the end jaw 4 is provided with a bevel that corresponds to the angle that results from the point of contact of the ink knife 11 on the ink fountain roller 1.
