PROBLEM TO BE SOLVED: To improve the degree of freedom of marking and the degree of freedom of lay-out of device with the simple structure by arranging an ink supplying unit near a wire, and discharging the ink from such ink supplying unit so as to adhere the ink to the surface of the wire. SOLUTION: An extruding machine 14 for extruding a wire insulating body 12, which is made of synthetic resin, to the surface of a wire conductor 10 is provided, and while an ink supplying unit 20 for marking the surface of the insulating body 12 is provided in the downstream of the extruding machine 14. A wire formed with the insulating body 12 is carried in the longitudinal direction by the extruding machine 14, and while a motor is continuously operated so as to always discharge the ink 18 from a nozzle 23, and a continuous straight mark can be thereby given to the surface of the insulating body 12. The ink 18 can be intermittently discharged by turning on and off the motor so as to give a dot mark, and while length and pitch of the mark can be freely adjusted by the operation of motor. Consequently, degree of freedom of marking and lay-out of the device can be improved. |
