Definitions

  • the invention relates to an ink fountain for rotary printing machines with an ink metering device comprising ink metering elements arranged next to one another in the axial direction for zone-by-zone adjustment of the width of ink strips to be transferred on the ink fountain roller.
  • a metering device which also regulates the ink film thickness and has slides which can be adjusted radially to the ink fountain roller is known from CH-A 608426 and from DE-A 2 951 653.
  • the ink fountain consists of an ink fountain upper part 2 and an ink fountain lower part 3. Between these parts 2, 3 they are radial to the Ink fountain roller 1 with its front edges A, B sprung ink metering plates 4, 5 positioned.
  • the overhead, somewhat longer plate 4 is pressed by two compression springs 6 with its front edge A against the ink fountain roller 1.
  • the springs 6 each have one end supported on the ink fountain lower part 3 and the other end on bolts 7 fastened to the plate 4.
  • the plate 4 is also attached to the ink fountain lower part 3 such that only a longitudinal movement of the plate 4 in the direction of the ink fountain roller 1 is possible, while the plates 4 are each laterally fixed. This is by Lan g holes 20 in the plate 4 easily possible.
  • the somewhat shorter plate 5 is arranged, which also resiliently abuts the ink fountain roller 1 with its front edge B.
  • two compression springs 9 are provided per plate 5, each of which is supported with one end on the ink fountain lower part 3 and with the other on the underside of the plate 5 supporting bolts 10.
  • each ink zone-wide plate 5 has an elongated hole 19.
  • An eccentric 11 engages in each one. This eccentric 11 is moved by means of a reduction gear 12 assigned to it via a ink zone servomotor 13 or conventional, manually actuatable ink zone adjustment screws 14 such that the lower plate 5 can be displaced in the axial direction of the ink fountain roller 1.
  • the front plate B always remains spring-loaded on the ink fountain roller 1 during the axial displacement.
  • the front edges A, B of the plates 4, 5 are provided with elevations 15, 17 and depressions 16, 18.
  • These recesses 16, 18 can be of any desired shape with regard to their geometric shape, but rectangular recesses are preferably suitable.
  • the support areas 15 of the plate 5 and support areas 17 of the plate 4 as well as the recesses 16 of the plate 5 and the recesses 18 of the plate 4 also lie one above the other.
  • the passage is the largest, that is to say the widest, in the axial direction of the ink fountain roller 1. Color rings with a maximum width corresponding to the maximum color requirement are thus generated for the color zone in question.

Claims (7)

1. Encrier (2, 3) pour presses à imprimer rotatives, comprenant un dispositif de dosage de l'encre comprenant lui-même des éléments de dosage de l'encre (4, 5) disposés les uns à côté des autres dans la direction axiale, qui servent à régler par zones la largeur des bandes d'encre à transférer qui sont portées par le rouleau d'encrier (1), caractérisé en ce que chaque élément de dosage de l'encre (4, 5) est composé de deux plaquettes superposées (4,5) qui sont appliquées élastiquement par leurs bords avant (A, B) contre le rouelau d'encrier (1), en ce que les bords avant (A, B) des deux plaquettes (4, 5) possèdent le même nombre d'encoches (16,18), et en ce qu'au moins une plaquette (5) peut être déplacée en translation dans une direction parallèle à l'axe du rouleau d'encrier (1) par un dispositif de réglage (11, 12, 13), de sorte que la position axiale relative des encoches (16,18) les unes par rapport aux autres détermine la largeur de la bande d'encre à transférer qui est portée par le rouleau d'encrier (1).
2. Rouleau d'encrier selon la revendication 1, caractérisé en ce que le dispositif de réglage (11, 12, 13) comprend un excentrique (11) qui est engagé dans un trou allongé (15) de la plaquette (5) et qui peut être mis en mouvement par un réducteur (12).
3. Encrier selon la revendication 1 ou 2, caractérisé en ce que chaque plaquette (4, 5) présente plusieurs encoches (16,18) sur son bord avant (A, B).
4. Encrier selon la revendication 3, caractérisé en ce que les encoches (16, 18) sont de forme rectangulaire.
5. Encrier selon une des revendications précédentes, caractérisé en ce que la plaquette (5) mobile en translation axiale est diposée au-dessous de la plaquette (4) qui est appliquée radialement contre le rouleau d'encrier (1 ).
6. Encrier selon une des revendications précédentes, caractérisé en ce que les plaquettes (4, 5) sont de longueurs différentes et que chacune peut être pressée contre le rouleau d'encrier (1) par au moins deux ressorts (6,9).
7. Encrier selon une des revendications précédentes, caractérisé en ce que la largeur de la plaquette (5) mobile en translation axiale correspond au pas de la division en zones d'encrage et en ce que la plaquette (4) bloquée dans la direction axiale possède une largeur à peu près égale à un pas ou à un multiple entier du pas de la division en zones d'encrage.
