Abstract: The present invention is to provide an apparatus for coloring an electrical wire to improve a visibility and design of the electrical wire. The apparatus includes a coloring device for ejecting a liquid coloring material to an outer surface of the electrical wire and a sliding device for moving relatively the coloring device in a direction perpendicular to a longitudinal direction of the electrical wire so as to color each whole outer surface of a plurality of coloring regions thereof responsive to a belt-shaped design pattern.

Abstract: A wire coloring apparatus including a roller is provided to prevent drag of a colorant, which is jetted on an electric wire and not dried yet, the guide roller is arranged at a downstream side of a coloring nozzle, which jets a colorant toward a highest point of an outer surface of the electric wire moving along a lengthwise direction thereof, in a moving direction of the electric wire. The guide roller is formed with a pair of tapered surfaces catching and supporting the electric wire and approaching to each other in accordance with nearing to a rotating axis. When a radius REW of the electric wire 3 is 1.2 mm, an angle ?T formed by the pair of tapered surfaces is designed at least 60 degrees and not more than ?X degrees.

Abstract: Providing a roller to prevent drag of a colorant, which is jetted on an electric wire and not dried yet, the guide roller 62 is arranged at a downstream side of a coloring nozzle 31, which jets a colorant Cm toward a highest point 3b of an outer surface of the electric wire 3 moving along a lengthwise direction thereof, in a moving direction of the electric wire 3. The guide roller 62 is formed with a pair of tapered surfaces 62b catching and supporting the electric wire 3 and approaching to each other in accordance with nearing to a rotating axis C. When a radius REW of the electric wire 3 is 1.2 mm, an angle ?T formed by the pair of tapered surfaces 62b is designed at least 60 degrees and not more than ?x degrees.
