Definitions

  • This industrial invention patent relates to a method for producing plastics cylinders for printing in general, and in particular rotogravure and flexography.
  • the patent also relates to the cylinder obtained by said method.
  • An object of the present invention is to provide a method for producing cylinders for printing in general, and in particular rotogravure and flexography, which is very simple to implement using any suitable apparatus.
  • a further object is to provide a method of the aforesaid type which enables plastics printing cylinders to be produced which are of maximum reliability and low weight, so that they can be easily handled and stored.
  • a further object is to provide a method which enables a plastics printing cylinder to be produced, the diameter of which can be varied at will during its production, without encountering particular difficulty.
  • the method of the invention consists essentially of (a) preparing an inner cylindrical tube of self-supporting rigid material, advantageously epoxy resin reinforced with glass or carbon filament or fabric, (b) coating said cylindrical tube with an expanded plastics material, advantageously rigid polyurethane, (c) making the outer surface of said coating perfectly smooth, (d) making said outer smooth surface of the expanded material electro-conductive by applying metallic materials in any manner, and (e) making said electro-conductive surface engravable, advantageously by applying electroplated copper or applying engravable photopolymer materials.
  • a glass fibre fabric or yarn impregnated with epoxy resin is wound about a perfectly cylindrical steel mandrel having a ground, lapped and chromium-plated surface, until a thickness of between 1.5 and 2 mm is obtained.
  • the structure is then polymerized in conventional manner at a temperature of between 80°C and 120°C.
  • the resultant tube is then mounted on the central shaft of a casting mould consisting of a cylinder in which said shaft is centrally positioned and which has its inner surface perfectly ground and lapped.
  • the mould is tightly closed and a quantity of polyurethane is introduced such that the final expanded product will have a density of 0,480 kg/dm3, said polyurethan being prepared by mixing isocyanate and polyol in stoichiometric proportion in a mixing machine.
  • Both the components and the mould are temperature-controlled at 20-35°C, and preferably at 30°C.
  • the structure obtained can be made electrically conductive by applying a silver or nickel-based paint by spray or brush to a thickness of 200 ⁇ c. Copper is then applied in an electroplating tank to a thickness sufficient to enable the required engraving of the cylinder surface to be effected, this thickness being advantageously 500 ⁇ C.
  • the thickness of the expanded polyurethane layer can be varied according to requirements without varying the dimensions of the internal tube, to enable cylinders of variable outer diameter to be mounted on the same standard support shaft.
