Definitions

  • the invention relates to an ink fountain for offset or high-pressure machines with an ink metering device, by means of which the respective ink gap can be set in zones in the axial direction of the ink fountain roller, the ink metering device being adjustable to the ink fountain roller via an elastic film and fastened by the elastic fastener which can be easily removed from the upper edge of the ink fountain Foil is covered.
  • a known version (US-PS 2 382 103) uses an ink fountain film, which is clamped with spring clips on the upper edge of the ink fountain.
  • the films used here are relatively stiff and must therefore be adjusted to the shape of the ink fountain by folding them. After a certain period of time, the foil on its contact surface on the ink fountain roller has worn out and must be replaced.
  • the circular section ground in by the ink fountain roller must not assume such an extent that the ink metering in the individual zones is adversely affected, or that even the front film area would be cut off, because otherwise the ink metering device would become contaminated.
  • the disadvantage of the known design is that the ink fountain must always be emptied to replace the film and that a new film is required in each case.
  • a dampening unit on offset printing machines in which a textile web is provided, the supply of which is stored on a roll arranged above the doctor blade and the used, soiled part of which is wound on a roller arranged in the frame below the doctor body. Due to the frictional force of the rotating rotary cylinder, there is a risk of the textile tape unintentionally rolling off the supply roll.
  • the ink fountain 1 is assigned a ink fountain roller 2 in a known manner, between which the ink 3 is filled in a wedge-shaped space. This is fed in a thin ink film from the ink fountain roller 2 in a known manner via a lifting roller to the inking unit rollers (not shown) and from there again transferred to the plate cylinder.
  • the thin color film can be adapted to the respective requirements via a color metering device 4 (FIG. 1).
  • the ink fountain 1 and the ink fountain roller 2 To clean the ink fountain 1 and the ink fountain roller 2, the latter is designed to be pivotable.
  • the length of the ink fountain 1 and the rollers is designed according to the paper format to be printed. In a known manner, the ink fountain and the rollers are mounted on both sides in printing unit side walls, not shown.
  • the color metering device 4 consists of zone-wide control elements 5 which, arranged closely next to one another, extend across the width of the ink fountain 1.
  • the adjusting elements 5 are cylindrical and are mounted in pressure bars 6 divided into zones. For this purpose, the pressure strips 6 have recesses 7 in their front area.
  • Both the control elements 5 and the pressure strips 6 are covered by an elastic film 8.
  • the compression springs 9, which are assigned to each pressure bar 6, press the adjusting elements 5 against the elastic film 8 and thus against the ink fountain roller 2, the desired ink gap being adjustable in zones by means of the adjusting screws 10.
  • the elastic film 8 is fastened in the upper region of the ink fountain 1 and normally extends on both sides to below the closure pieces 11, which seal the ink space laterally, and are clamped in place by means of the screws 12.
  • the elastic film 8 is easily removed from a tensioning spindle 14 which extends over the length of the ink fountain.
  • the clamping spindle 14 has a longitudinal slot 15.
  • the clamping spindle 14 can be rotated via the screw 16 and the lever 17, the screws 16 being supported on the lateral holders 18.
  • the bearing 19 for the clamping spindle 14 is fastened to the upper edge 13 of the ink fountain 1 by means of the screws 20.
  • the elastic film 8 is moved tangentially to the ink fountain roller 2, so that after moving a new, not worn part of the Film surface rests on the ink fountain roller 2.
  • the longitudinal slot 15 for hanging the film could then assume the position shown in broken lines in FIGS. 1 and 2.
  • the screws 12 for the side closure pieces 11 must be loosened somewhat and tightened again after the displacement process.
  • FIG. 3 shows an embodiment of the invention in which the elastic film 8 is suspended from a bar 2q in the upper region of the ink fountain 1. Parallel to this, further strips 22 and 23 are attached to the ink fountain, which extend over the length thereof. To move the elastic film 8 relative to the ink fountain roller 2, this can e.g. hang in the bar 22 (dash-dotted lines) so that a new, not worn part of the film surface rests on the ink fountain roller.
  • Figure 4 shows the elastic film 8 suspended in the strip 21 with an underlying rod 24 with a rectangular cross section, the longer edge of the rectangle being perpendicular to the film so that a larger displacement path is achieved.
  • the rod has been folded over, which means that a smaller displacement path is set. It is advantageous for the printer to first carry out the smaller displacement path.
