Abstract
PURPOSE:To remarkably increase the etching multiplying factor by passing Al foil through the inside of a main etching vessel having a bottom shielding plate in a liq. etchant dipping tank when the Al foil is etched in the etchant by applying an electric current with the foil as an anode. CONSTITUTION:When the surface of the Al foil for an electrolytic capacitor is etched in the production of the foil, the Al foil 11 is passed through the inside of the etchant 12 in the dipping tank 13 through a feeder roll 20, directed upward by a turning roll 22, passed between the bottom shielding plates 15 and 16, and introduced into the main etching vessel 14. An electric current is supplied between the foil 11 as the anode and cathodes 17 and 18, and the surface of the foil 11 is etched. Since the leakage of the etching current is interrupted by the bottom shielding plates 15 and 16, the electric current increases rapidly at the initial stage, the effect of the gas generated during etching is mitigated, and the Al foil is etched at a high rate.
