Abstract:
An apparatus for producing metal foil, comprising:a drum cathode having an outer plating surface, said drum cathode being partially immersed to a set level in an electrolyte bath and being rotatable in a fixed direction about a generally horizontal axis; a main anode assembly having a main anode immersed in said electrolyte bath, said main anode having a semi-cylindrical curved anode surface facing said drum cathode, said main anode being dimensioned to be spaced from said plating surface of said drum cathode so as to define a generally uniform gap therebetween; an energy source connected to said main anode for energizing said main anode; a chamber containing an electrolyte solution disposed above said electrolyte bath and adjacent said cathode drum where said cathode drum exits said electrolyte bath; a treatment anode immersed in said electrolyte solution in said chamber adjacent said drum cathode; and an energy source connected to said treatment anode for energizing said treatment anode.
