Abstract:
1. An apparatus for manufacturing an electrolytic metal foil, comprising: an electrolytic cell containing electrolyte; an upper drum installed in an upper portion of the electrolytic cell to be rotatable and to which a negative (−) electric potential is applied; a lower drum soaked in the electrolyte of the electrolytic cell and installed to be rotatable together with the upper drum; a cathode belt mounted around outer circumferences of the upper and lower drums to move along an endless track and electrically connected to the upper drum so that the negative (−) electric potential is applied thereto; and an anode unit installed to form a space from a metal electroplating surface of the cathode belt soaked in the electrolytic cell so that a positive (+) electric potential is applied thereto, the anode unit having a slit for supplying the electrolytic to the space; a fixing member successively coupled to an entire side end of the cathode belt and slidably contacted with sides of the upper and lower drums; an O-ring interposed in a concave groove formed at a border between the fixing member and an electroplated metal electroplated on the cathode belt; a first roller for guiding the O-ring to be successively inserted into the concave groove before the cathode belt is soaked in the electrolyte; and a second roller for guiding the O-ring to be successively departed from the concave groove when the cathode belt moves up above a surface of the electrolyte.
