  • the support member 23 is positioned on the conducting ring 7 so that the electrically conductive surface 33 of the cross arm members 31 is in electrical contact with the conducting ring 7.
  • the weight of the support frame 23, with the cylinder to be plated is sufficient to effect the desired electrical contact between the electrically conductive surfaces 33 of the cross arm members 31 and the conducting ring 7, without the need for clamps or similar positive securing means.
  • such securing means may be used, although their use could make it difficult to utilize the present apparatus in a fully automated system, unless such securing means were automatically, rather than manually, actuated.
  • a cylindrically shaped article to be plated, 45 such as a Gravure cylinder, is mounted in the support frame 23 in electrical contact with the cylinder engaging surfaces 39 of the lower and upper engaging members 27 and 29.
  • the cylinder 45 is supported in a substantially vertical position within the reservoir 1, below the level of the electroplating solution contained therein.
  • the support frame 23 is provided with centering collar members 47 which are disposed within the lower and upper engaging members 25 and 27, which centering collars have an internal diameter which will permit the supporting shafts 49,at each end of the cylinder 45, to be inserted into them.
  • the upper engaging member 29 is removed from the vertical support members 25 and a centering collar 47, having the proper internal diameter, is inserted in the lower engaging member 27.
  • a cylinder 45 to be plated is then inserted into the lower engaging member 27 with the shaft 49 at one end of the cylinder inside the centering collar 47 in the lower engaging member and the end of the cylinder resting on the sealing ring 41 on the cylinder engaging surface 39.
  • a second centering collar 47 is placed over the cylinder shaft 49 at the upper end of the cylinder and the upper engaging member 29 is then placed over the shaft and collar so that the sealing ring 41 on the cylinder engaging surface 39 of the engaging member 29 rests on the upper end of the cylinder 45 which is to be plated.
  • the sealing rings 41 are both deformed to the extent that the electrically conductive portions of the cylinder engaging surfaces 39 on both of the members 27 and 29 are brought into electrical contact with the ends of the cylinder 45.
  • the cylinder is thus supported in a substantially vertical position in the support frame 23, which frame is then inserted into the reservoir 1 and supported on the electrically conducting ring 7 so as to provide electrical contact between this ring and the electrically conducting surface 33 on the cross arm members 31 of the support frame.
  • the reservoir 1 is also provided with a suitable bus or electrical brush member 51 which is in electrical contact with the conducting ring 7.
  • This bus member is connected to a suitable source of electrical power (not shown).
  • anode members 53 are disposed within the reservoir, between the side walls 3 and the cylinder 45 which is to be plated. These anode members are provided with an electrical connection which is external of the reservoir, so that they may be connected into the electrical circuit. Desirably, there are a plurality of anodes which are spaced apart equidistant around the cylinder to be plated. It is generally preferred that these anodes are disposed so as to be partially above the level of the electroplating solution, so that the fastening member or hanger is not in the plating solution.
  • anodes may be used, including solid anodes, anode bags or baskets and the like and that these will be copper where the cylinder is to be copper plated.
  • the surfaces of the support member or frame 23 which are in contact with the electrolyte solution in the reservoir are coated with an electrically insulating material, so that there is no electroplating of these surfaces.
  • the electroplating of the cylinder in the reservoir is effected by the passage of current from the bus member 51 to the conducting ring 7, from the conducting ring to the electrically conductive surface 33 of the cross arm members 31, from the surface 33 through the vertical support members 25 to the electrically conductive cylinder engaging surfaces 39 on both the lower and upper engaging members 27 and 29. From here, the current flows through the cylinder 45 to be plated, which is the cathode, through the electroplating solution to the anodes 53, which anodes are of the metal which it is desired to plate on the cylinder 45, such as copper. As the electroplating of the cylinder is being effected, the entire support member or frame 23 is being rotated, thereby obtaining improved quality in the electroplate produced while reducing the plating time.
  • FIG. 4 shows an alternative configuration for the support member or frame 23, which configuration has in many instances been found to be preferred.
  • the support member 23 is made up of the vertical support members 25 and the upper and lower engaging members 29 and 27, mounted thereon.
  • the screw threads 35 on the vertical support members 25 extend downwardly from the cross members 31 a greater distance than in the configuration shown in FIG. 3, so that when the entire assembly is placed within the reservoir 1, the level of the electrolyte is above part of the screw threads. This then makes it possible to obtain more adjustment of the frame to accomodate a greater variety of cyliner lengths.
  • the screw threads are electrically conductive and would thus be plated during operation, they are provided with a moveable sleeve 55 of an electrically non-conductive material. This sleeve may be moved up or down the members 25 to cover that portion of the screw threads 35 which is in the electroplating solution, thus providing electrical insulation.
  • the upper and lower engaging members 29 and 27 are each provided with spring members 57, disposed within the engaging members. These spring members provide the electrical contact with the cylindrical object to be plated and further serve to center and hold the object within the engaging members. Thus, these spring members take the place of the centering collars 47used in the embodiment shown in FIG. 3. Various types of spring members may be used which will permit the insertion of different sizes shafts 49 of the cylinder 45 so as to hold the shaft and provide electrical contact with it. With this arrangement, the need for a plurality of centering collars to accomodate a variety of shaft sizes is eliminated, thus simplifying the apparatus and making it more versatile.
  • the engaging surfaces 39 are provided with a sealing ring 41.
  • the surfaces 39 need not be electrically conductive, as they do not provide the point of electrical contact with the cylindrical object to be plated.
  • adjusting rings 59 which rings each have a sealing ring 61. These adjusting rings 59 are positioned between the ends of the cylinder 45 and the engaging surfaces 39 of the upper and lower engaging members 29 and 27.
  • the adjusting rings may be formed of an electrically non-conductive material or they may be metal coated with a plastisol or similar electrically non-conductive coating or paint. The size of these adjusting rings should be such that the shaft 49 of the cylinder 45 can pass through them and so the sealing rings 41 will contact them on one side and the sealing rings 61 will contact the ends of the cylinder 45.
