  • Patent number: 8844858
    Abstract: 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 (the number of rotation, and timing) 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.
