ABSTRACT:
This invention intends to provide a method and apparatus for manufacturing an electric wire, capable of easily changing a color applied to the electric wire. The electric wire manufacturing apparatus intends to manufacture an electric wire composed of a core and a cladding. In step S1, the core is supplied from a supply unit. In step S2, in an extrusion cladding unit, the outer periphery of the core is coated with non-color synthetic resin by extrusion cladding to form the cladding. In step S3, the outer surface of the cladding is colored by a coloring unit. The coloring unit includes a plurality of sprayers15and16. In step S3, the sprayers15and16are exchanged to operate as necessary. In step S4, in a take-up unit, the electric wire is cut into segments each having a desired length, which are wound around a drum.
