Definitions

  • This invention relates to improved printing apparatus and more particularly to improved inking rollers for proved ink distribution rollers for use in printing pressesand the like. Another object is to provide improved ink distribution rollers which are highly resistant to the corrosive effects of modern printing inks and which have porous surfaces to improve the ink transmission characteristics of the rollers.
  • Ink rollers according to the invention comprise cylindrical cores having porous yet hard surface coatings of a corrosion resistant metal such as stainless steel, tungsten or molybdenum.
  • An ink distribution roller as shown in the drawing comprises a hollow cylindrical core 2 having axially extending shafts 4 which may be journalled in any suitable bearings (not shown) to mount the cylinder for rotational movement.
  • the core 2 may be made of any desired material such as steel or cast iron having suflicient strength to withstand the stresses and strains that may be encountered in operation of the roller in an inking system.
  • the core 2 bears a coating 6 on its outer surface of a relatively hard, corrosion resistant porous metal.
  • Porosity of the coating 6 is achieved by the method of applying it to the surface of the roller.
  • the coating 6 is applied by metal spraying according to the well known Schoop method which produces a strongly adherent and uniform but porous coating.
  • the coating is preferably made about one millimeter thick in order to provide fully effective anti-corrosion protection for the surface of the cylinder 2 upon which it is applied.
  • the coating may be made thicker than one millimeter if desired, but, since this thickness has been found to provide fully adequate anti-corrosion protection, it is preferred to limit the coatings to about one millimeter in order to minimize the cost of the rollers.
  • the porosity of the coating 6 increases the ink transmission efficiency of the roller, and the nature of the coating material insures a long service life with negligible wear or corrosion.
  • the coating 6 maybe cut after it is applied to produce thereon an embossed pattern such as a fine screw thread to increase lateral ink distribution axially along the roller, or a diamond pattern 8 such as is shown in the drawing further to increase its ink handling capacity.
  • a pattern may be produced by any known cutting method, such as by grinding or etching. Care must be taken, of course, not to cut completely through the coating 6.
  • At least about 0.6 millimeter or more 2,908,068 Patented Oct. 13, 1959 ess produces a relatively rough and porous surface layer which is capable of relatively efiicient ink transmission.
  • Rollers according to the invention are particularly use ful as ink distribution rollers to transfer ink from a source such as an immersion roller "onto a printing plate. Because of the porosity and roughness of the surface layer rollers according to the invention, they tend to take up more ink from the source than do smooth rollers. They also tend to distribute the ink over their own surfaces Wi-th an improved uniformity.
  • the materials suitable for use in coating rollers according to the invention are not critical. It is essential, how ever, to select a material that is relatively hard, corrosion resistant and susceptible to spraying by the Schoop method. It has been found that stainless steels such as 18-8 (SAE 30615) and 18l0 (SAE 30805) and pure metals such as tungsten and moylbdenum all give satisfactory results.
  • a rigid cylindrical core having a surface coating of a hard, porous, corrosionresistant spray-deposited metal bonded to its outer surface, said coating having embossments forming a pattern to improve the ink transmission capabilities of the roller, the thickness of said coating being approximately one millimeter, the minimum thickness of said coating at said embossments being suflicient to provide anti-corrosion protection for said core.
  • a rigid cylindrical core having a surface coating of a hard, porous, corrosionresistant spray-deposited metal bonded to its outer surface, said coating having embossments forming a. pattern to improve the ink transmission capabilities of the roller, the thickness of said coating being approximately one millimeter, the minimum thickness of said coating at said embossments being at least 0.6 millimeters.
