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 adjusted 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 embodiment (US Pat. No. 2,382,103) uses spring clips to fasten the film to the ink fountain, with which the foil is clamped at 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 grinded in by the ink fountain roller must not be so large that 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.
the object of the invention is to provide an ink fountain in which the useful life of the film is extended and in which fewer empties of the ink fountain are required.
the object is achieved by the characterizing part of claim 1. This makes it possible to move the film several times over the ink fountain roller and thus to extend its service life accordingly. Side work, such as B. emptying the ink fountain are not required when moving the film Lich.
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 ink 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 adjusting 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 actuating 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 via 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 tensioning spindle 14 is rotated, the elastic film 8 is displaced tangentially to the ink fountain roller 2, so that after the displacement, a new, not worn part of the film surface rests against 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 21 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 of the same. To move the elastic film 8 relative to the ink fountain roller 2, this can, for. B. 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.
FIG. 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 is folded, whereby a smaller displacement path is set. It is advantageous for the printer to first carry out the smaller displacement path.
