摘要： PURPOSE:To make the outer diameter of the core uniform, by providing a means of sending out an inner conductor through a sender, a means for reducing the diameter of the inner conductor before extruding a synthetic resin material and a means for extruding, cooling and solidifying the synthetic resin material and then heating, cooling and solidifying it again. CONSTITUTION:The inner conductir 11 is pulled from a feeder A into a sinking unit 14 by the sender 13. The outer diameter of the inner conductor 11 is reduced and uniformly shaped by the sinking unit 14 and therafter supplied onto an extruder 17 through a washer 15 and a preheater 16. The extruder 17 extrudes the synthetic resin material on the inner conductor 11, thereby molding a spiral string and a tube simultaneously. The inner conductor is introduced into a sizing unit 18 while the synthetic resin material remains semi-molten. Thereby, the inner conductor and the synthetic resin material are uniformly molded and integrated with each other. Then, the insulated core C is passed through a cooler 19, a heater 20 and a re-cooler 21 and then coiled.
