ELECTRICAL CABLE, APPARATUS AND METHOD OF COLORING AND MANUFACTURING SAME

摘要

An object of the present invention is to provide a more recognizable mark on an outer surface of an electrical cable. An apparatus (1) for manufacturing an electrical cable (3) includes a coloring unit (12) to form a sinusoidal mark on an outer surface of the electrical cable (3) with ejection of a coloring material. The coloring unit (12) includes coloring nozzles (32a-32c) for continuously ejecting coloring materials onto the outer surface of the electrical cable moving in a longitudinal direction thereof; and a vibration device (20) disposed upstream of the coloring nozzles (32a-32c) for vibrating the electrical cable (3) in a direction orthogonal to the direction of movement of the electrical cable (3) and a direction of ejection of the coloring material.
