A method according to claim 1 including the step of filtering small nickel particles which may pass from said anode to said cathode.
Claim 2
Independent Claim
82 words
A method for making a nickel foil from an electrolytic solution comprising the steps of: placing a solution of nickel compounds into a tank; continuously passing outside surface portions of a unitary, seamless, self supporting, titanium or titanium alloy cathode drum into and out of said solution; providing a nickel anode in said solution which conforms to and is in proximity with immersed portions of said surface portions; electrically energizing the cathode; agitating the solution; and stripping nickel foil from said surface.
