A dangler cable for use in both horizontal and oblique electroplating processes is disclosed. The dangler cable includes an electrical cable having an insulating sheath surrounding a plurality of groups of wire strands. One end of the electrical cable is stripped of the insulating sheath, whereby a portion of the wire strands extend from the insulating sheath. A cathode member having a metal sleeve is secured to the stripped end of the electrical cable by crimping one end of the sleeve coaxially of the electrical cable and flattening the other end of the sleeve. In addition, the other end of the electrical cable is provided with a connector member to secure the dangler cable to a bus bar of an electroplating apparatus. There is also disclosed the method of using the novel dangler cable in an electroplating process and the method of securing a cathode member to an electrical cable.

The processing apparatus comprises a rotatable barrel supported from a stationary cross bar by a pair of stationary U-shaped hanger arm and collar bearing assemblies of rigid construction, with one assembly opposite each end of the barrel. Inner portions of the collar bearings are received in openings provided in the ends of the barrel and upon which the barrel is adapted to rotate about the axis of the barrel. The outer portions of the collar bearings are located outside of the barrel and are provided with circumferentially extending annular grooves which surround the axis of the barrel. The ends of the U-shaped hanger arms are secured to mounting lugs provided on the cross bar, with the bottoms of the U-shaped hanger arms being located in the grooves and wrapped around the collar bearings. The hanger arms are each secured in two places, one to the corresponding mounting lug and the other to the corresponding stationary collar bearing.
