Definitions
- the invention relates to a short inking unit for an offset rotary printing press with an anilox roller according to the preamble of claim 1.
- An anilox roller transports ink from a chambered doctor blade system onto an inking roller. The diameter of the anilox roller is smaller than that of the inking roller.
- the invention has for its object to provide a short inking unit with a screened inking roller, plate and blanket cylinders, all of which have the same scope, for a web-fed rotary printing press, the fountain solution consumption of which during the printing process is significantly reduced compared to the prior art.
- the advantages that can be achieved with the invention are, in particular, that the dampening water consumption during Printing is reduced by up to 50%. Despite the low consumption of fountain solution, there is no toning. The ink is emulsified significantly less with fountain solution, which results in a more brilliant print image, especially in multi-color printing.
- Fig. 5 shows a fifth embodiment of the short inking unit according to the invention.
- a dampening unit preferably a brush dampening unit, which delivers an amount of dampening solution to the inking cylinder 3.
- the ßürstenfeuchtechnik consists of a brush roller 8, a fountain solution roller 9, a dampening cylinder 7 and a dampening roller 6, which delivers the dampening solution to a form cylinder 4.
- a paper web 15 is printed between the blanket cylinders 5.1 and 5.2.
- two additional rollers 13 and 14 are mounted in the side frames 12 or in a pivotable frame.
- the pivotable frame is mounted so that it can bring the roller 13 out of contact with the forme cylinder 4.
- the rollers 13, 14 remain in contact with the ink application cylinder 3 when the roller 13 together with the ink application cylinder 3 is turned off from the forme cylinder. Farbauftra cylinder 3 and roller 13 are turned on and off together on the forme cylinder 4.
- the rollers 13, 14 run under pressure against one another without their own drive.
- the roller 13 is provided with an oleophilic rubber jacket and makes a reciprocating movement in its longitudinal axis direction. She is employed in the printing operation on the forme cylinder 4.
- the roller 14 is covered with an oleophilic jacket, e.g. B. provided a polyamide sheath, and makes a back and forth movement in the longitudinal axis direction.
- This oleophilic jacket of the roller 14 transports a layer of printing ink which is coated on the outside with a finely divided surface dampening solution, e.g. B. water, is wetted and / or has in its interior emulsified with the dampening solution "printing ink.
- the roller 14 can also be provided with a jacket made of a hydrophilic material, e.g. B. chrome. But it can also run without the back and forth movement. Drives for generating the back and forth movement are known and are not the subject of the invention.
- Roller 14 is driven by friction from the inking cylinder 3.
- rollers 13 and 14 can also be mounted on the right side - the side on which the dampening unit is arranged.
- fountain solution applicator roller 6 and first roller 13 are in rolling contact with the same jacket half of the forme cylinder 4, ie the first roller 13 has contact with the part of the forme cylinder 4 on which the "used" ink flow runs back to the doctor blade (return ink flow).
- the second roller 14 is of course then arranged on the right side of the inking cylinder 3 and is in rolling contact with it and the first roller 13.
- Roller 13 is in each case pressed against the forme cylinder 4 - incidentally like the other rollers and cylinders - and form with it a line of contact 20.
- This line of contact 20 lies in the stream of "fresh color", ie. H. on the circumference of the left half of the forme cylinder 4 or in the flow of the "used” ink on the right half of the forme cylinder 4.
- the roller 14 and inking cylinder 3 are pressed against one another and form a line of contact 21.
- This line of contact 21 lies depending on the arrangement the roller 13 in the "return" color stream, i. H. on the circumference of the left half of the inking cylinder 3 (Fig. 1) or in the "fresh” ink stream on the right half of the inking cylinder 3 (Fig. 2).
- roller 22 with an oleophilic coat from z. B. rubber and another roller 23 with an oleophilic coat z. B. arranged polyamide.
- the roller 23 can with one be known drive connected so that it performs a reciprocating movement in the longitudinal axis direction via gears.
- the roller 22 runs under pressure with the roller 14, the roller 23 under pressure with the roller 22 and the inking cylinder 3 and are driven by friction.
- the rollers 22 and 23 can have their own drive.
- the roller 23 is thus once in the "used” ink stream (FIG. 3) or in the "fresh” ink stream (FIG. 4) on the inking cylinder 3.
- roller pair (s) 24, 26 can namely be in rolling contact with the inking cylinder 3 in the "fresh" ink flow when the rollers 13, 14; 22, 23, as described in Fig. 4, are arranged.
- the rollers 24, 26 can have a drive for their reciprocation in the longitudinal axis direction.
- the rollers 13, 14, 22, 23, 24, 26 can have the same, but also different diameters.
