摘要:
An apparatus for removing, through reverse electrolysis, an electroplating metal deposited onto the surface of a conductor roll for electroplating. The above-mentioned removal is accomplished by means of a reverse-electrolylzing electrode (23) provided in the electroplating solution near the conductor roll (5). The start and the end of the removal can properly be controlled on the basis of a value of potential difference between a reference electrode (21) immersed in the electroplating solution and the conductor roll (5), as measured by means of a potentiometer (25). The reverse-electrolyzing electrode (23) return-travels, together with the reference electrode (21), in the axial direction of the conductor roll (5) by the action of a reverse-electrolyzing electrode moving mechanism (30).
