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).

摘要： An apparatus for removing, by means of a scraper, an electroplating metal deposited onto the surface of a conductor roll for electroplating. The above-mentioned removal is accomplished by pressing the scraper (23) arranged near the conductor roll (5) against 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 scraper (23) return-travels, together with the reference electrode (21), in the axial direction of the conductor roll (5) by the action of a scraper moving mechanism (30).
