Abstract:
An apparatus for producing metal foil, comprising:a drum cathode having an outer plating surface, said cathode being partially immersed to a set level in an electrolytic solution and being rotatable about a generally horizontal axis;an anode assembly, comprised of:a main anode portion immersed in said electrolytic solution, said main anode portion having a semi-cylindrical curved anode surface facing said drum cathode, said main anode portion being dimensioned to be spaced from said plating surface of said drum cathode so as to define a generally uniform gap therebetween, andan anode extension portion disposed at the upper end of said main anode, said anode extension portion having a first zone having at least one opening formed therein, said first zone being spaced a predetermined distance from said plating surface of said cathode, at least a portion of said anode extension being immersed in said electrolytic solution; andone energy source connected to said anode assembly for energizing said main anode portion and said anode extension portion at the same electrical potential.
