Patent ID: 8128790

Claim:
An apparatus for performing an electrolytic plating on a plating surface of a belt substrate, comprising: a plating tank; a conveyor device configured to carry a belt substrate through an interior of the plating tank; an auxiliary driver device positioned in an interior of the plating tank and configured to convey the belt substrate, the auxiliary driver device comprising an immersed cathode power-supply roller, an auxiliary cathode power-supply roller and a short-circuit wiring configured to short-circuit the immersed cathode power-supply roller to the auxiliary cathode power-supply roller, wherein at least one of the immersed cathode power-supply roller and the auxiliary cathode power-supply roller maintains electrical continuity with a plating surface of the belt substrate, the immersed cathode power-supply roller and the auxiliary cathode power-supply roller are positioned on a non-plating surface side inside the plating tank, one of the immersed cathode power-supply roller and the auxiliary cathode power-supply roller is a drive roller, and the other one of the immersed cathode power-supply roller and the auxiliary cathode power-supply roller is a dependent roller which rotates according to the drive roller.
