Definitions
- the invention relates to a dampening medium Lwa Lze for a dampening unit of an offset rotation printing as chi ne according to the preamble of claims 1 and 5.
- a disadvantage of this drive is that both the rings of the abutment and the elastic coating of the driven dampening agent Lauf t ragwa lze consist of different materials.
- a further disadvantage is that the ring-shaped supports located at the ends of the P lattenzy have a larger diameter than the P Lattenzy linder due to the clamped pressure plates, and are made of a different material.
- US 51 91 835 A describes a dampening unit of a rotary printing press with four dampening rollers.
- One that works directly with the forme cylinder The dampening solution roller t ragwa lze is frictionally driven, while the dampening solution rollers upstream of this dampening agent roller t ragwa Lze are positively driven by means of gear wheels.
- the invention has for its object to a dampening medium Lwa lze
- the dampening agent lwa Lze has a uniform elastic coating over its entire surface, in which both sides can be inexpensively formed as a result of a "puncture". This means that no additional abutments are required.
- the dampening solution roller can be adjusted with its drive rings to any roller of the dampening unit provided with a hard surface and can be driven by it without additional supports being required for this.
- the dampening agent lwa Lze according to the invention is particularly advantageous to an iridescent, d. H. in the axial direction reciprocable driven damp rei bwa Lze adjustable.
- the drive rings have a damp-guiding profile. This is particularly useful when there is an iridescent chrome roller in the dampening solution path in front of the dampening agent roller.
- an even application of dampening solution over the width of the dampening agent is Moisturizing agent given.
- FIG. 1 shows a longitudinal section through the schematic representation of a dampening unit.
- FIG. 2 shows a detail "Z" according to FIG. 1 with the enlarged illustration of a drive ring arranged on the dampening solution roller;
- Fig. 3 shows a profiled support ring.
- a dampening unit 1 for a lattenzy L i nder 2 one
- Spray bar 3 which acts against a chrome roller 4, a dampening medium according to the invention, ragwa roller 6, an oscillating dampening roller 7 and a dampening agent application roller acting against the plate cylinder
- the spray bar 3 can be designed as a known spray nozzle system.
- the damp rei bwa lze 7 is by non-intent l lte means, z. B. a gear train from
- P lattenzy L i nde r 2 driven and can be made of chrome or
- Ceramics e.g. aluminum oxide or chromium oxide exist.
- Each dampening medium lwa 6; 8 has a rubber load i see Coating 9, e.g. B. a rubber jacket.
- the dampening agent lwa Lze 6; 8 has an effective bale length or working width of b11 + c (c eg 10 mm) compared to a maximum width b11 of a paper web 11.
- the working width te b11 + c is limited on both sides by annular grooves 13 located on the circumference 12 and introduced into the coating 9. Beyond the ring grooves 13 are ends 14; 16 of the dampening solution transfer roller 6 with a coating 9 of the same material having the same diameter e, e.g. B. rubber, the drive rings 17; 18 provided.
- the drive rings 17; 18 have a width d, z. B. of 30 mm each.
- the changeable damp rei bwa lze 7 has an effective working width b11 + c + f and has an axial stroke length f, z. B. of ⁇ 15 mm.
- the chrome roller 4 has a length that extends beyond the working width b11 + c on both sides by the amount d.
- the aforementioned cylinders and rollers 2; 4; 6; 7; 8 are tenste L Lf est stored, as is the spray bar 3rd
- the mode of operation of the dampening medium lwa Lze according to the invention is as follows:
- the spray bar 3 transfers the dampening solution to the chrome roller 4 over the working width b11 + c. It remains at both ends the chrome roller 4 in each case an area d beyond the working width b11 + c dry or provided with only a little moisture, so that the chrome roller 4 drives via the friction rings 16; 17 receives the dampening solution roller 6.
- Moisturizing medium ragwa Lze 6 receives 4 dampening solution from the chrome roller and passes it on to the changing damping bwa Lze 7.
- the drive of the dampening solution transfer roller 6 is frictionally through the two areas f of the damp rei bwa lze 7, which on the drive rings 17; 18 the dampening agent surprises ragwa 6 wi rken.
- dampening roller 7 delivers the rubbed dampening solution to the dampening medium bearing roller 8, which moistens the pressure plates of the plate cylinder 2.
- the dampening agent running t ragwa Lze 8 is driven by both the changing damp rei bwa lze 7 and the plate cylinder 2 by means of friction.
- the dampening solution roller 8 are none Drive rings 17; 18 needed.
- the chrome roller 4 can be driven and oscillated by means of a gear train from the flat plate cylinder 2 instead of the changing and driven dampening roller 7.
- the chrome roller 4 can be driven and oscillated by means of a gear train from the flat plate cylinder 2 instead of the changing and driven dampening roller 7.
- the drive rings 17; 18 can both for the frictional drive of the drive rings 17; 18 dampening solution roller can be used as well as to drive a directly interacting roller. It is also possible to have only one end 14; 16 to be provided with a drive ring. There is also the possibility, for example, of the chrome roller 4 with drive rings 17; 18 to be provided. These can, for example, see a rubber coating 9 on white.
- a humid lab leading profile 19 can, for. B. from on the jacket of the drive rings 17; 18 helical circumferential grooves 21, which the dampening solution in the direction of the ends of the dampening medium roller 6; 8 transport away.
