<p>A coloring nozzle for an electric wire, capable of reliably jetting a drop of a coloring material by a fixed amount at a time toward a desired position on an outer surface of an electric wire. A coloring nozzle (31) for an electric wire jets a drop of a liquid coloring material by a fixed amount at a time toward an outer surface of an electric wire and colors the wire. The coloring nozzle (31) has a hollow cylinder-like first nozzle member (37) inside which the coloring material flows in the direction of arrow Q and a second nozzle member (50). The first nozzle member (37) and the second nozzle member (50) are coaxially connected to each other. The second nozzle member (50) is provided closer to an electric wire than the first nozzle member (37). The inner diameter (d) of the second nozzle member (50) is smaller than the inner diameter (D) of the first nozzle member (37). An end face (50a) on the first nozzle member (37) side of the second nozzle member (50) projects more inward of the first nozzle member (37) than an inner surface of the first nozzle member (37). The end face (50a) is flat in the direction perpendicular to (intersecting) arrow Q.</p> |
