1. An improved apparatus arrangement for electrolytic processing of a longitudinally extended metal workpiece comprising:

  • (a) means to pass a longitudinally extended metallic workpiece having at least one surface to be coated along a pass line through containment means for a body of electrolytic solution bathing such surface to be coated, (b) an electrode mounted closely adjacent the pass line of said metallic workpiece within said containment means in contact with said electrolytic solution, (c) at least one thin substantially solid laterally extended dielectric means substantially bathed by the electrolytic solution and extending adjacent to the electrode generally transversely of said longitudinally extended metallic workpiece to at least periodically contact the surface of the workpiece along a relatively narrow line of contact to simultaneously space the workpiece from the electrode and wipe the surface of the workpiece, (d) means to move the longitudinally extended workpiece along the pass line past the transversely extended dielectric means within the electrolytic solution, and (e) wherein the thin substantially solid laterally extended dielectric means has a workpiece contacting surface formed from a high lubricity plastic material.
