PURPOSE:To reduce material loss, time loss and economical loss to a substantial extent by providing a process of coating resin for insulation extruded out of an extruder onto a conductive material and forming an insulated layer, a process of mixing a liquid coloring agent of desired color into color identification basic resin after being extruded and preparing the identification color resin and a process of coating the same onto the insulated layer and forming the color identification layer. CONSTITUTION:A mixer 7 is inserted in the middle of an extrusion line 61 connecting an extruder 6 extruding base resin for color identification and a resin coating head 4, and a liquid coloring agent 8 of desired color is fed from a storage tank into the upper section of a mixer 7 of the extrusion line 61 by a press feeding pump 9. The mixer 7 works for mixing the liquid coloring agent 8 and base resin for a color identification layer by, for instance, rotating a worm or an impeller, and the basic resin mixed with the liquid coloring agent 8 is turned by the mixer 7 into identification colored resin of desired color, fed into the resin coating head 4, and thus coated on an insulated layer 2 as a color identification layer 3. |
