1. An improved arrangement for electrolytic coating of an elongated flexible metallic substrate comprising:

  • (a) means to pass a longitudinally extended cathodic workpiece having at least one surface to be coated through containment means for a body of electrolytic solution containing metallic ions to be plated out upon and bathing such surface to be coated,(b) an anode mounted closely adjacent the pass line of said cathodic workpiece within said containment means in contact with said electrolytic solution,(c) at least one elongated resilient narrow surface contact dielectric means arranged generally transversely of said longitudinally extended cathodic workpiece to resiliently contact the surface to be coated of the cathodic workpiece along an extended narrow contact interface between said surface of the workpiece and the resilient narrow surface contact dielectric means while submersed in the body of electrolytic solution,(d) means to move the longitudinally extended cathodic workpiece past the resilient narrow surface contact dielectric means, and(e) means to replenish electrolytic solution within the body of solution to prevent said body of electrolytic solution from becoming depleted of coating metal ions at the electrolyte-cathode interface.
