Abstract

A device for electroplating portions of a continuously moving, cathodically connecting workpiece as it is moved past a plurality of anodically connected spray nozzles characterized by the spray nozzles comprising precious metal and being positioned one after another in a row along the direction of movement of the workpiece with each of the nozzles having an individual stream of electrolytes emerging unimpeded therefrom. The continuously moving workpiece is positioned so that selected portions thereof are moved along the row of nozzles to be contacted by the stream of electrolyte emerging from the individual nozzles for a free and unimpeded electroplating of the portions contacted by the streams.
