Abstract:
1. A plating device comprising: a fixed drum in which a counter electrode is exposed on the external peripheral surface; a rotor rotatably disposed via a prescribed gap on the external periphery of said fixed drum, and onto the external periphery of which a belt-shaped or linear workpiece transported in the longitudinal direction is wound with a prescribed arc of contact range; an annular opening formed by the peripheral surface of said rotor onto which said workpiece is wound, and provided so as to continue in the peripheral direction of said rotor and penetrate from the external periphery to the internal periphery of the rotor; a plating solution feeding channel formed inside said fixed drum having an open end corresponding to an angle position of said prescribed arc of contact of the rotor onto which said workpiece is wound; and a plating solution feeding system, enclosed by the workpiece wound onto the external periphery of said rotor, the peripheral wall of the annular opening formed in said rotor, and the external periphery of said fixed drum, for feeding the plating solution from said solution feeding channel to a duct using a tunnel-shaped space along the external periphery of the fixed drum as said duct, and discharging the plating solution from both ends of said tunnel-shaped space in which said workpiece and the rotor move away from each other.
