Metal foil electrolytic manufacturing apparatus

Abstract

An object of the present invention is to provide an apparatus for electrolytically manufacturing a metal foil which can precisely control the uniformity of the foil thickness in a transverse direction of the metal foil, when the metal foil is continuously manufactured through the electroprecipitation by the use of a drum-like rotating cathode. The present invention is an apparatus for electrolytically manufacturing a metal foil comprising a drum-like rotating cathode which electrodeposits the metal foil thereon, an anode whose surface is oppositely disposed along a contour of a peripheral surface of the above described rotating cathode, and solution-supplying means having an electrolyte-supplying inlet for supplying an electrolyte in between the rotating cathode and the anode from an underside of the rotating cathode, the metal being electrodeposited onto the peripheral surface of the rotating cathode through an electrolytic reaction while supplying the electrolyte from the solution-supplying means, then the metal foil electrodeposited being continuously released from the rotating cathode, in which the solution-supplying means has a plate-like damper body extending in a transverse direction of the rotating cathode above the electrolyte-supplying inlet.

1 . An apparatus for electrolytically manufacturing a metal foil comprising a drum-like rotating cathode which electrodeposits the metal foil thereon, an anode whose surface is oppositely disposed along a contour of a peripheral surface of said rotating cathode, and solution-supplying means having an electrolyte-supplying inlet for supplying an electrolyte in between the rotating cathode and the anode from an underside of the rotating cathode, 
 the metal being electrodeposited onto the peripheral surface of the rotating cathode through an electrolytic reaction while the electrolyte being supplied from the solution-supplying means, then the metal foil electrodeposited being continuously released from the rotating cathode,    wherein the solution-supplying means has a plate-like damper body extending in a transverse direction of the rotating cathode above the electrolyte-supplying inlet.    
     
     
         2 . The apparatus for electrolytically manufacturing a metal foil according to  claim 1 , wherein the plate-like damper body is provided with a projection for divergence extending in a longitudinal direction of the plate at a center of a width of the plate.  
     
     
         3 . The apparatus for electrolytically manufacturing a metal foil according to  claim 1  or  2 , wherein which the electrolyte-supplying inlet is divided into a plurality of sections in the transverse direction of the rotating cathode and a flow rate of the electrolyte supplied from each section of the divided electrolyte-supplying inlet can be regulated.
