ABSTRACT:
Disclosed is a method of making electrolytic metal foil, comprising carrying out electrolysis by filling with an electrolytic solution a space defined between a cathode drum capable of rotating on a horizontal axis and an anode provided in face of the surface of the drum, wherein the electrolytic solution is allowed to flow down from the upper part toward the lower part of the space at the flow velocity such that a gas generated in the solution during the electrolysis may virtually flow out downward in its whole quantity. Disclosed also is an apparatus for making electrolytic metal foil, comprising a cathode drum capable of rotating on a horizontal axis, an anode provided in face of the surface of the drum and provided a solution discharging outlet which allow a gas generated during the electrolysis to flow down the space between the both electrodes at the flow velocity such that the gas generated may downward flow out virtually in its whole quantity together with an electrolytic solution for metal electrodeposition.
According to this invention, the resulting electrolytic foil can be of dense texture and of excellent physical properties and surface states.
