Patent number: 6361673Abstract: An apparatus for producing metal foil, comprising a drum cathode having an outer plating surface. The drum cathode is partially immersed to a set level in an electrolyte bath and is rotatable in a fixed direction about a generally horizontal axis. A main anode assembly having a main anode is immersed in the electrolyte bath, the main anode having a semi-cylindrical curved anode surface facing the drum cathode. The main anode is dimensioned to be spaced from the plating surface of the drum cathode so as to define a generally uniform gap therebetween. An energy source is connected to the main anode for energizing the main anode. A chamber containing an electrolyte solution is disposed above the electrolyte bath and adjacent the cathode drum where the cathode drum exits the electrolyte bath. A treatment anode is immersed in the electrolyte solution in the chamber adjacent the drum cathode. An energy source is connected to the treatment anode for energizing the treatment anode.Type: GrantFiled: June 27, 2000Date of Patent: March 26, 2002Assignee: GA-TEK Inc.Inventors: Thomas J.
