Abstract
A wire twist-preventing device in a winding machine of the invention comprises a flyer for forming a coil by winding a plurality of wires, which are arranged parallel with one another in a tape shape, around a winding frame having a plurality of winding stages which gradually increase upward in winding diameter, when the winding frame is lowered stage by stage, a dummy flyer which is rotated together with the flyer; and a dummy drum rotatably provided coaxially with the winding frame and having a circumferential length which is substantially equal to an average circumferential length of the winding frame, wherein the wires are wound around the winding frame by the flyer while they are wound around the dummy drum by the dummy flyer.
