<p>PROBLEM TO BE SOLVED: To provide a manufacturing device for an annular concentrically twisted cord having the high winding accuracy of a side wire around an annular core.SOLUTION: A manufacturing device for an annular concentrically twisted cord includes: a core rotation mechanism 10 for rotating an annular core 1 in a circumferential direction; a first cassette moving mechanism 20 for moving a cassette 50 to the outside and inside of a ring of the annular core 1; a second cassette moving mechanism 30 for moving the cassette 50 from one side to the other side of a rotation shaft of the annular core 1 on the inside of the ring of the annular core, and moving the cassette 50 from the other side to the one side of the rotation shaft of the annular core 1 on the outside of the annular core 1; and a speed adjusting portion 19 for decreasing the rotation speed of the core rotation mechanism 10 or increasing the moving speed of the cassette 50 by the first cassette moving mechanism 20, with increase in a number of circulations of winding of the side wire 2 around the annular core 1.</p> |
