Definitions
- the invention relates to an inking unit for a printing unit of a Ro L Lenrot at i onsdruc k aschi ne according to the preamble of claims 1, 2 and 3.
- a short inking unit for a rotary printing press has become known from GB-PS 18 907 and DE 195 35 266 A1.
- the following measures are provided to improve the printing ink application on a forme cylinder:
- a first inking roller has a smaller diameter than the form cylinder
- first ink transfer roller (rider roller) is attached to the first inking roller
- This additional inking unit roller is an inking roller connected to a central inking roller - here, for. B. a rider roll
- the further inking roller based on the direction of rotation of the central inking roller, is in contact with the central roller before the first inking roller.
- DE 35 45 720 A1 shows a short inking unit with an anilox roller, with the non-rasterized Full of color, good color coverage should be achieved.
- the same principle of printing is applied as in the above-mentioned publications GB-PS 18 907 and DE 195 35 266 A1. This is because two inking rollers are used, both of which are in contact with an anilox roller. After the printing ink has been delivered by the first inking roller to a first roller, its residual printing ink application is given to an inking roller in accordance with the inking law. This then delivers ink to the first roller.
- the invention has for its object to provide an inking unit for a rotary printing press.
- the inking unit can be realized in a low overall height and, when using chambered doctor blades or doctor blade devices, directly on a central printing ink "distributing" ink roller, even in a short overall length.
- two inking rollers can be set up with a plurality of inking rollers, each applying an ink to a common forme cylinder.
- each inking roller train can be pivoted in such a way that the operator has practically all of the inking rollers of the corresponding inking roller train "in front of his stomach".
- Fig. 1 is a side view of a schematic
- FIG. 2 shows an illustration analogous to FIG. 1, but with an inking unit with a rider roller placed on the inking roller;
- Fig. 4 shows another embodiment.
- An inking unit 1 e.g. B. a short inking unit for a rotary printing press, consists essentially of an ink application device 3, which is an ink application emits an ink pickup roller 2 (hereinafter referred to as “central roller 2" or “roller 2").
- the ink application device 3 can, for. B. consist of a known doctor blade 5 but also consist of several rollers in contact with each other, their ink application z. B. from a conventional paint box or a pump or Fa rbauf spray i nri device etc. obtained.
- One or more inking rollers can be provided.
- rollers 2 of other constructions can also be used.
- Keram k jacket e.g. Fe 0
- the ceramic or glass jacket can also be gridded or manufactured in another way
- Inking rollers 12; 13 at least one ink roller 16; 17 in contact with oleophilic coat.
- This can be designed as an oscillating ink roller.
- With the color application (s) 12; 13 and each of the inking roller 16; 17 is a first rider roller 29; 31 in touch with her oleophilic coat. It can be designed as an oscillating roller.
- On the inking rollers 12; 13 can each have a rider roller 38; 39 with an oleophilic coat. They are each on the inking rollers 12; 13 can be switched on and off.
