Patent ID: 8721863

Claim:
A method for plating a belt substrate, comprising: moving a belt substrate by a conveyor device such that the belt substrate moves through a plating tank; conveying the belt substrate in an interior of the plating tank by an auxiliary device positioned in the interior of the plating tank such that the belt substrate makes contact with the auxiliary device and becomes a cathode; and electrically plating a surface of the belt substrate in the interior portion of the plating tank while the auxiliary device maintains cathode power-supply to the belt substrate conveyed into the interior portion of the plating tank, wherein the auxiliary device includes an immersed cathode power-supply roller, an auxiliary cathode power-supply roller and a short circuit wiring device electrically connecting the immersed cathode power-supply roller and the auxiliary cathode power-supply roller such that at least one of the immersed cathode power-supply roller and the auxiliary cathode power-supply roller maintains the cathode power-supply to a plating surface of the belt substrate, the immersed cathode power-supply roller and the auxiliary cathode power-supply roller of the auxiliary device 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 configured to convey the belt substrate, and the other one of the immersed cathode power-supply roller and the auxiliary cathode power-supply roller is a dependent roller configured to rotate according to the drive roller.
