Abstract
An electroforming apparatus for producing metal foil having a rotating drum cathode and an improved anode construction and a process for using the apparatus are described. The improved anode construction comprises an arcuate anode having a perforated zone. The perforated zone is placed over a manifold for distributing electrolyte into a gap between the cathode and anode for providing a more uniform current distribution and a more uniform foil deposition in the plating region over the manifold as well as other advantages.
