Definitions

  • the invention relates to a coated paper guide roller for a web-fed rotary printing press with a cylindrical base body and a jacket with a rough ink-repellent surface which is intimately connected to the base body.
  • Such paper guide rollers are used in order to largely avoid the depositing of printing ink on the paper guide roller driven by friction when the paper web is printed on both sides.
  • German utility model G 73 45 259.2 it is known to provide the base body of a paper guide roller with a droplet layer applied in a flame spraying process and consisting of droplets projecting from the carrier substance in one layer next to one another. Funnel-shaped depressions remain between the droplets. This creates a sufficiently rough surface so that slippage between the non-driven paper guide roller and the paper web rolling on it, which drives the paper guide roller by friction, is avoided. A high chromium content in the droplet material results in an additional color-repellent effect.
  • the surface layer In the case of spherical coverings, the use of glass spheres embedded in a rubber-like carrier layer and protruding from the rubber surface is known as the surface layer.
  • the glass balls form a hard surface and are also color-repellent.
  • micro-coated covers are only for driven rollers can be used because the surface is too smooth to drive the roller by friction. With a lower packing density of the glass balls, a satisfactory result with regard to the avoidance of ink deposits on the roller surface could not be achieved, since a rubber layer has oleophilic properties.
  • a wear-resistant coated paper guide roller which on the one hand has a surface which is fine enough so that folds on the paper web can be leveled out and is easy to clean, and on the other hand to achieve friction is sufficiently rough that slippage is avoided and high print quality is maintained.
  • a deposit or sticking of the paint on the surface should be prevented or reduced.
  • the object is achieved in that the cylindrical base body of a paper guide roller, which can be made of gray cast iron or steel, with a jacket made of a first layer surrounding the surface of the base body made of an ultrahigh molecular weight plastic and a second layer applied intimately to the first is preferably surrounded by the same base material as a carrier substance for single-layer mixed-in glass spheres.
  • Polyethylene or polytetrafluoroethylene can be used as the ultra-high molecular base material.
  • the effect achieved according to the invention is also achieved if different high-molecular plastics are used as base material for the first and second layers, for example for the first layer polyethylene and for the second Layer of polytetrafluoroethylene or vice versa.
  • a thermal spray process for example a flame spray process, can advantageously be used to apply the first and second layers.
  • the relatively quickly solidifying first layer can be applied in one operation, for example by means of a flame spray gun Base body, which shows a sufficiently high affinity for plastic, can be applied, with the help of a downstream flame spray gun, the second layer can be applied with the glass balls.
  • glass balls protruding uniformly from the carrier substance are distributed over the surface of the casing of the paper guide roller, the density of which determines the roughness of the outer layer.
  • the polyethylene or polytetrafluoroethylene used as a carrier for the glass spheres and for the first layer is very color-unfriendly, comparable to high-molecular candle wax.
  • the first layer ensures that the glass balls of the second layers applied to this first are embedded deep enough in a plastic layer.
  • the glass balls themselves have the function of protecting the ink-repellent plastic layer from wear and of protruding from the carrier substance to ensure the roughness necessary for the friction drive of the paper guide roller.
  • the paper guide roller designated 1 has a cylindrical base body 2, for example made of gray cast iron or steel, which consists of a jacket 3 which is intimately connected to the base body 2 and consists of a first layer 4 of high-molecular plastic and a second layer 5 forming the surface of the jacket 3 same base material of the first layer 4 is surrounded as a carrier substance for glass balls 6 mixed in in one layer.
  • the thickness of the first layer 4 is approximately 300 ⁇ m. Values of approximately 200 to 1,000 ⁇ m can occur as the diameter for the glass balls of the second layer 5.
  • glass balls with a diameter of 300 ⁇ m are preferably used, which protrude from the carrier substance of the second layer 5 by about 20% of their diameter to the surface, an average number of mm 2 per mm 2 distributed a maximum of 70 balls. Since, as shown in the figure, the second layer 5 is thinner than the diameter of the glass balls 6, the glass balls 6 partially extend into the first layer 4, so that there is good embedding in the color-repellent plastic. The roundness of the elevations on the surface of the paper guide roller 1 and the comparatively low roughness depth of the second layer 5 enable the latter to be cleaned easily.
  • the loose density of the glass ball arrangement in the second layer 5 on the one hand ensures sufficient friction to avoid slippage and on the other hand prevents the ink from depositing due to the color-repellent carrier substance.
