Abstract
An electroplating apparatus having a tank containing a bath of an electrolytic solution, and a roll supported for immersion into the electrolytic bath for transporting a sheet material through the bath. The roll has a current collector rotatably supported on a shaft thereof for transmitting high amperage electricity to the roll. The current collector is supported on a part of the shaft which projects exteriorly of the tank side wall, and incorporates a sleevelike housing structure which surrounds and is rotatable relative to the shaft and mounts therein a plurality of conductive shoes which are of a highly electrically conductive material and are spring urged for snug radial contact with a conductive ring secured to a conductive sleeve arrangement which snugly axially and nonrotatably mounts to the shaft. The housing cooperates with the sleeve arrangement to define a generally sealed interior annular chamber in which the current-conducting shoes are positioned. A pressurized lubricating system is connected to the current collector for permitting substantially continuous supply of lubricant through the chamber.
