ABSTRACT OF THE DISCLOSURE In a continuous electrolytic foil forming process employ- ing constant d.c. voltage, the foil is drawn through the electrolyte at automatically adjusted speed by a feed-back mechanism so as to maintain a constant value of forming current, thereby producing an oxide film whose thickness is substantially invariant over the entire length of the foil.
