Definitions

  • the invention relates to a clamping cylinder and a method for clamping cylindrical embossing dies for embossing rollers, especially for Embossing diffractive gratings or holograms on plastic foils and other substrates.
  • embossing forms have a partial or all-over structured surface, which after the embossing shape on the clamping cylinder was clamped into a rotating endless process Embossing lacquer is molded. Because the lacquer layer that is embossed is relatively thin, preferably "endless" embossing forms used that neither a butt edge or butt joint nor a bulky Show seam.
  • Tensioning cylinders for similar purposes are known from printing technology. Indeed are those used there and clamped on the clamping cylinder Printing plates thick-walled and very solid, so that the clamping cylinder mechanically because of the high clamping forces that occur during clamping is adjusted accordingly. For example, in printing technology flexible printing forms made of rubber-like materials, the other clamping mechanisms require used. In some printing processes come too thin metallic plates are used as printing form, e.g. magnetic and be excited.
