Definitions

  • the present invention relates to a cylinder jacket profile according to the preamble of Claim 1.
  • Such a cylinder jacket profile is known from DE 42 07 119 C2, wherein a Counter-pressure or sheet guide cylinder has a surface coating that is ground parallel to the impression cylinder axis.
  • the cylinder jacket profile is vertical cylindrical elevations arranged to the cylindrical surface. their Cylinder length is 20 to 200 ⁇ m and their screen fineness is 400 to 10,000 Dots / cm2.
  • the printing cylinder has a surface coating Chrome into which the cylinder jacket profile is etched. This consists of individual statistical ones evenly distributed surveys.
  • the disadvantage is the high Surface energy of chrome with 78 mN / m because of the associated Soiling problems or smearing of the freshly printed surface as well the complex manufacturing process.
  • Non-stick coating for example made of Teflon or silicone with a typical layer thickness of about 20 ⁇ m.
  • the disadvantage of this is particularly that Layer-induced strong changes in the surface structure of the printing cylinder and the associated increasing deterioration in the printing result.
  • the Wear resistance as well as the chemical resistance to the cleaning and Printing chemicals of these non-stick coatings are low.
  • such coated printing cylinders often insufficiently the sheet during the printing process hold.
  • non-stick coatings with are very well known low surface energy.
  • amorphous, diamond-like Carbon layers with CVD or PVD processes with typical layer thicknesses of 1 deposited up to 10 ⁇ m.
  • Wear-resistant non-stick layers can be used low surface energy or tension (typ. 20 - 40 mN / m) for Surface finishing of tools, for example, can be realized.
  • Colloid technology is a new technology for non-stick coating Surfaces with layer thicknesses from 100 nm to 10 ⁇ m.
  • This technology uses the Complex formation of a polyelectrolyte with fluorosurfactants.
  • the exposed to the outside Surfactant layer, which itself is only up to 1 nm thick, is characterized by extreme Smoothness and extremely low surface tension from (11 - 16 mN / m).
  • inorganic-organic hybrid polymers With inorganic-organic hybrid polymers, the incorporation of functional Groups of, for example, perfluorinated silane compounds in the silicate backbone Layers with anti-adhesive properties are created that are not only water-repellent (hydrophobic), but also oil and fat repellent (oleophobic) and therefore one have improved protection.
  • the surface properties achieved have an effect reduced adhesion of dirt particles and thus good cleaning behavior.
  • a sol-gel process e.g. apply a coating by dipping or spraying the basis of inorganic-organic nanocomposites with low free surface energy (approx. 19 mN / m) and high scratch and abrasion resistance thanks to fluorinated organic Groups can be produced as a single cleaning layer.
  • a self-cleaning surface which a has artificial surface structure from elevations and depressions.
  • the Distance between the surveys in the range of 5 to 200 microns and at least the surveys consist of hydrophobic polymers or durable hydrophobic materials, the elevations not being detachable by water or by water with detergents are.
  • the object of the present invention is to solve the problems currently existing in the To reduce sheet guiding in perfecting, especially that To improve the cleaning behavior of a cylinder jacket profile.
  • the cylinder surface is provided with a surface structure. It is irrelevant whether the structure is on the surface of the cylinder itself or on a layer or jacket applied to the cylinder is produced.
  • the cylinder with a structured surface in the spray, jet or Impression processes are formed.
  • a coating with a thin and low-energy light cleaning layers like this provided that the surface structure is not essentially in its dimension being affected.
  • the light cleaning layer is applied to a structured chrome layer is applied. Due to the low thickness, the easy cleaning layer after just a few revolutions of the impression cylinder in the Contact area in the surveys must be rubbed off. The generation of the high Back pressure then takes over the chrome layer, while the printing ink in the Depressions of the cladding profile hardly adhere due to the easy cleaning layer or is easy to remove.
  • the cylinder jacket profile is included dome-shaped elevations and / or depressions. This is a good one Cleanability of the surface realizable, with a sufficiently high back pressure can be achieved in the printing process. In addition, such an edge and step-free surface simply coated evenly. Alternatively, however also pyramid-like, cylindrical, frustoconical dome-shaped or irregularly structured surveys are provided on the surface. Also one Mixtures of the various structural forms can be used according to the invention.
  • the structured surface with the characteristics according to the combination of the Claims 1 to 3 can according to the invention the sheet without slipping or Scratch and is only slightly worn out at the same time.
  • the on the wear-resistant chrome coating applied low-energy coating is used in areas where the bow has no direct contact with the Cylinder jacket profile has to accept little or no color. If the light cleaning layer is not sufficiently wear-resistant, it will Use removed in the contact areas with the paper sheet. However, this is unproblematic, since the low-energy light cleaning layer prefers its Effect should only develop between the support points of the arch.
  • a plate cylinder 10 is provided on an offset printing press which a printing plate is stretched, which has the information to be printed. After printing ink is applied to the plate cylinder 10, the ones to be printed Transfer areas to a blanket cylinder 12. In the pressure gap between the Blanket cylinder 12 and a so-called impression cylinder or impression cylinder 14 then a sheet of paper or a paper web 16 is guided.
  • the profile of the Printing cylinder surface 14 has a multilayer structure (FIG. 2a). It is first a nickel layer 18 as a base layer with a dome-shaped Surface provided, which in turn is covered with a thin chrome layer 20.
  • the nickel layer 18 can also be realized with a flat surface, wherein only the chrome layer 20 is dome-shaped with evenly distributed arrangement Elevations and depressions is applied (not shown). Typical distances between the elevations are between 20 and 100 microns, typical thicknesses of the Chrome layer 5 to 10 ⁇ m.
  • the chrome 20 dome structure is as Light cleaning layer 22 overlays a roughened microstructure, its strength is preferably between 10 nm and 2 ⁇ m and the one known lotus effect has, which leads to a known self-cleaning effect (Fig. 2a).
  • This layer 22 can be used, for example, as an amorphous carbon layer, in colloid technology or as a sol-gel lacquer to be provided. It is also possible to remove the layer by deposition the gas phase, for example by plasma polymerization, plasma-assisted chemical Deposition from the gas phase (PE-CVD) or similar processes can be generated.
  • PE-CVD plasma-assisted chemical Deposition from the gas phase
  • the light cleaning layer 22 can also be a completely smooth microstructure be designed with a free surface energy of 10 to 50 mN / m.
  • the strength of the Light cleaning layer 22 is chosen so small that it corresponds to the respective Requirements for the printing cylinder 14 optimized surface profile of the chrome layer 20 not adversely or falsely changed.
  • the microstructure 22 is provided on the elevations of the dome structure 22 is not absolutely necessary, since on these Make a smooth counter pressure surface is desired. It is therefore sufficient if the microstructure or light cleaning layer 22 only in the recesses of the Cylinder jacket profile is present where it exerts its self-cleaning effect.
  • a dome structure with the additional Easy cleaning microstructure 22 has.
  • the dome structure ensures that randomly or undesirably applied to the printing cylinder 14 color particles in the Wells of the dome structure 20 can run and accordingly at Exercise of counter pressure on the paper sheet 16 can not be transferred to this, because only the elevations of the dome structure made of chrome 20 against the paper sheet to press.
  • the surface design of the spherical structure ensures that the Ink is repelled as a result of the light cleaning layer 22, and a Adhesion of the color on the impression cylinder 14 is avoided, and at the same time Sufficiently high back pressure due to the wear-free surface made of chrome 20 is provided (Fig. 2b).
