  • Patent number: 4340449
    Abstract: A plurality of articles are advanced in continuous sequence in spaced relation to each other through an electroplating bath to pass in sliding engagement with a pair of lands, thereby to move selected, laterally-extending strips of the articles along an anode surface located between the lands in selected, closely spaced, facing relation to the anode surface. Jets of the electroplating solution are directed through a plurality of openings in the anode surface to provide a continuous positive flow of electroplating solution in a direction from the anode surface against the selected strips of the articles moving past the anode surface and to permit the flow of electroplating solution to pass between the articles while the lands substantially restrict the flow of the electroplating solution in other directions. Electrical current is directed through the flowing electroplating solution between the anode surface and the article strips for plating the selected article strips to a desired thickness.
