ABSTRACT:
A method of continuously electrolytically treating a metal web in an electrolytic liquid using an alternating waveform current via a pair of main electrodes such that the surface of the metal web experiences both an anode reaction and a cathode reaction. The ratio of the current value contributing to the anode reaction acting on the surface of the metal web and the current value of the cathode reaction acting on the surface of the metal web is controlled by shunting a portion of the supplied current to an auxiliary electrode, which is separated from the main electrodes, as a direct current.
