    • PROBLEM TO BE SOLVED: To improve a success rate of yarn insertion in a core yarn-producing apparatus for producing a core yarn using a core fiber as an elastic yarn. SOLUTION: The core yarn-producing apparatus 1 is equipped with a four wires type draft device 100, an elastic yarn feeder 200, a guide pipe 10 for determining a protruding position P of an elastomer 3 to the draft device 100 and an air sucker 6 flying the elastic yarn 3 from the interior of the guide pipe 10 toward the protruding position P. In the core yarn-producing apparatus 1, the shape of an outlet 10a of the guide pipe 10 is formed in elliptical shape which becomes longitudinal in feed-out direction Ds of a sheath fiber 2.
