Abstract
A conductive contact ring for an electroplating or electrodeposition process on a cylindrical surface includes a frame defining an opening through which the object can be passed and an array of electrically conductive fibers spanning the opening. The frame is electrically conductive and is connected to a DC power source in the process. Two or more contact rings can be used in a process to provide consistent electrical contact with the surface sliding therethrough. A single contact ring can have first and second groups of filaments spaced from each other along the axial length of the surface.
