Definitions

  • This invention relates to a roller which feeds a supply of an adherent fluid medium from its hollow interior onto its surface, and it more particularly relates to an inking roller of this type for a pr nting machine.
  • inking rollers used in printing machines are covered by a layer of an absorbent porous substance such as felt or sponge rubber.
  • This absorbent surface layer retains a supply of ink fed into it from holes extending through the hollow cylinders upon which these layers are applied.
  • This ink is picked up from the feeding cylinder by transfer rollers, and it is then either directly or indirectly applied to the material to be printed.
  • the pores of the absorbent layer must be arranged in accordance with the viscosity of the ink that is being fed, which is usually a liquid, to allow the ink to be easily picked up by the transfer roller without dripping from the storage cylinder when it is not being operated.
  • inking device air pressure is applied to the storage cylinder either periodically or continuously to permit it to operate at a constant supply pressure. This distributes the ink more uniformly and increases the ability of the machine to be prepared for immediate operation at all times.
  • this type of inking device uses a prohibitively great amount of ink.
  • this pressurized arrangement is only suitable for applying liquids but not pastes.
  • the perforations through the storage cylinder must be made in only a sing e line which must be positioned at the top of the roller whenever it is stopped to allow the liquid to feed only during the inking operation.
  • An objectof this invention is to provide a simple and economical roller for feeding an adherent fluid medium which uniformly distributes the medium over its surface and does not drip when it is not operating.
  • an elastic tube of plastic material is fitted closely over the surface of a perforated storage cylinder.
  • This plastic tube incorporates holes which are disposed out of alignment with the perforations in the cylinder for controlling the flow of the medium from the hollow interior of the cylinder onto the surface of the tube.
  • These perforations are preferably uniformly distributed over the surfaces of the tube and cylinder and are particularly efiective when the spaces within which the ink might deposit or crystallize are maintained as small as possible.
  • annular projections are formed upon the inner surface of the tube around the holes in it to help uniformly feed the ink with minimum frictional resistance.
  • These annular projections form a space between the walls of the tube and the surface of the cylinder which has an insignificant storage volume, but is capable of always maintaining the holes in the tube fully supplied with medium. This space increases the elasticity of the tube in the direction of feed, and the optimum height of these projections is preferably at least one-half of the thickness of the tube but no greater than this thickness.
  • the ends of the tube are made imperforate for sealing the ends of the space provided by the annular projections extending between the surface of the cylinder and the inner Wall of the tube.
  • the diameter of the unstretched plastic tube can be originally made smaller than the outer diameter of the surface of the storage cylinder to permit the ends of the tube to be stretched tightly over the surface of the cylinder. It is also possible to provide fla. rings extended within the ends of the tube to facilitate their sealing contact over the ends of the cylinder.
  • the medium such as ink may be supplied into the hollow interior of the storage cylinder through an aperture in the surface of the tube or through a hollow axle where automatic feeding is desired.
  • KG. 1 is a longitudinal cross sectional view taken through one embodiment of this invention
  • FIG. 2 is a partial enlarged view of a portion of a modification of the embodiment shown in FIG. 1;
  • FIG. 3 is a diagrammatic side view in elevation of an embodiment of this invention in its operating relationship.
  • roller 17 made in accordance with this invention which includes circular ends 1 and 2 joined by a cylindrical member 3.
  • Parts 1, 2 and 3 are, for example, made of a relatively strong resinous plastic material such as polyvinyl chloride.
  • Roller 17 includes a pair of axles la and 2a, and it also includes a hollow interior 4 which is filled with an adherent fluid medium 5 such as ink.
  • Adherent fluid medium 5 is, for example, a liquid ink.
  • pastes are also suitable inking material. It is also possible to provide a hole do similar to passageway 8 axially disposed through axle la or 2a to permit the medium to be continuously fed as the roller is rotated in operation.
  • Cylinder 3 may, for example, have a mean diameter ranging from 20 mm. to 40 mm. and a wall thickness of approximately 2 mm.
  • a number of perforations ii are, for example, uniformly distributed over the surface of cy inder 3. These holes 11 are, for example, approximately one-half mm. in diameter.
  • a plastic tube 12 fits cylinder 3 to substantially uniformly fill space 14.
  • Tube 12 incorporates holes 13 which are preferably uniformly distributed over the surface in stag- ,gered relationship out of alignment with holes 11. These holes v,13 are formed, for example, by applying pressure from outside to inside of tube12 to form annular projections 13a upon the inner surface of tube 12 around 'holes 13. These annular projections 13:: form a space .14 between the inner wall of tube 12 and the surface of cylinder 3. The diameters of holes 13 and the height of projections 13a are for example, slightly greater than the wall thickness of tube 12.
  • an adherent fluidmedium such as-ink, for example incorporating a dyestuff
  • an adherent fluidmedium such as-ink, for example incorporating a dyestuff
  • transfer roller 18 As the rollers rotate, an adherent fluidmedium such as-ink, for example incorporating a dyestuff, is drivenby the applied centrifugal force through perforations 11 in Ink is forced from space 14 into holes 13 by theradial pressure exerted by transfer roller 18 at itspointJof contact with roller 17.
  • This ink spreads over the surface of plastic hose 12 radially about holes 13.
  • This ink need not extend completely over the surface of the entire plastic tube to provide a uniform distribution of ink over printing roller 19.
  • the radialpre'ssure of trans- .fer roller 18 causes 'the entire surface of plastic tube 12 'to be covered substantially uniformly with a coating of ink within two or three revolutions.
  • the centrifugal force created during rotation is still able to force the ink through holes 11 and 13 and to maintain a fine film between tube 1 2 and cylinder 3 in a smaller space 14 which is still of sufficient magnitude to uniformly supply a flow of ink to holes 13.
  • adherent fluid mediums such as thin liquids having low viscosity are being fed.
  • the optimum configurations of the tube, the cylinder and their perforations are dependent upon the type of medium that is being fed and-applied.
  • a roller for feeding an adherent fluid medium comprising a perforated hollow storage cylinder, an elastic tube of plastic material fitted closely over the surface of said storage cylinder, and said plastic tube incorporating holes which are disposed out of alignment with the "perforations in said cylinder, andportions of said plastic tube contacting said surfaceof said storage cylinder between'substantially all'of said holes'and all of saidperforations to provide a resilient seal that separates said holes from said perforations for controlling'the flow of said mediumfrom the hollow interior of said cylinder onto the surface of said tube.
  • annular projections are disposed around said holes upon the inner surface of said tube, and said annular projections providing said contacting portions of plastic tube andforming a space between the inner wall of said tube and the surface of said cylinder.
