Definitions
- the invention relates to a dampening unit according to the preamble of claim 1.
- EP 07 19 639 A2 shows a dampening unit with four rollers.
- EP 04 62 490 A1 discloses a four-roller dampening unit in which a dampening roller and a friction roller have the same speed.
- the invention has for its object to provide a high pressure quality requirements sufficient dampening unit.
- z. B. a sufficient for a 1/1-pressure two-roller dampening unit as needed, for. B. for a four-color newspaper printing, be retrofitted to a three-roll dampening unit with higher moisture quality. It is also possible, with even higher quality standards, eg. B. for a semi-commercial production, magazine or magazine production with little effort to retrofit a fourth roller for the dampening unit.
- the drive between the friction roller and the dampening roller creates a uniform dampening solution distribution with simple drive means.
- a dampening unit 01 for a printing unit of a rotary printing press consists of a friction roller 04 which is rotatably mounted in a side frame 03 with shaft journals 02.
- the friction roller 04 has a hard outer surface, e.g. B. chrome. It is drivable by means of a drive, not shown, and can be reciprocated in the axial direction with a certain stroke.
- a plate cylinder 06 is arranged on the friction roller 04 and the plate cylinder 06 engagable, rubber-elastic coated applicator roller 07 is arranged.
- the application roller 07 is by means of adjusting and holding elements 08, z. B. pivot levers 09, with Achszapfenträgem 11 and working cylinders 12 on the aforementioned facilities and off.
- the friction roller 04 is by means of a known fountain solution source 13, z. B. the spray jets of a spray nozzles 13 having spray bar moistened.
- a dampening unit 14 is a to the Friction roller 04 additionally engageable, rubber-elastic coated transfer roller 16 is provided, which by means of the adjusting and holding elements 08 analog actuating and holding means 17 to the friction roller 04 on and off.
- a dampening unit 21 In a dampening unit 21 according to a third embodiment (FIG. 3), additional bores are provided opposite the second dampening unit 14 in the side frames 03 for receiving shaft bearings 18 in a further roller 19 with a hard lateral surface arranged at a distance a from the friction roller 04 the lateral surface of the friction roller 04.
- the further roller 19 operates without axial stroke and z. B. by the friction of the friction roller 04 and to the further roller 19 swinging transfer roller 16 moves, which works here as an intermediate roller.
- the further roller 19 and the friction roller 04 have approximately the same peripheral speed.
- the side frames 03 of the rotary printing press are equipped with additional holes for receiving the retrofittable transfer roller 16 and other rollers 19.
- the further roller 19 is driven by the friction roller 04 positively.
- the drive takes place for example by means of a belt drive or gear transmission.
