a wire winding device which uses a large - sized supply bobbin , which has a large capacity and a large diameter , to highly precisely suppress a variation in tension which variation occurs when a coil is formed by winding a wire material at high speed with the wire material aligned with a winding frame . rotation of the supply bobbin relative to rotation of the coil is controlled based on the difference between the amount of take - up of the wire material taken up on the winding frame side and the amount of pay - out of the wire material paid out from the supply bobbin , and the control is performed such that the amount of the take - up and the amount of the pay - out agree with each other every moment . this can highly precisely suppress a variation in tension even if there are large differences between inertia of and the diameters of the coil and the supply bobbin .
