Abstract
A cylindrical electrolytic treatment vessel, containing an electrolyte and serving as one electrode, rotatably mounts in a concentric manner a cylindrical rotary body which is mounted for rotation horizontally about its axis. The cylindrical rotary body has enlarged diameter portions at opposite axial ends and at least the peripheral surfaces of the enlarged diameter portions are made of an electrically insolative material. The rotor body has a central smaller diameter portion intermediate of the enlarged diameter portions which is formed of metal and constitutes a second electrode. Electricity is applied between the treatment vessel and the cylindrical rotor body electrode. The metal web is rotatably supported along opposed side edge portions of the web by the electrically insulative surfaces of the enlarged diameter portions of the body so that continuous electrolytic treatment is effected to the metal web as it passes through the electrolyte.
