PURPOSE: An automatic arranging and winding spool bobbin is provided to wind a wire automatically by forming a threaded part around a core and a gap between the threaded part of the core and a flange, and to prevent wire from being omitted by bending the flange to the core. CONSTITUTION: An automatic winding spool bobbin is composed of a core(11) having a threaded part(11a) in the periphery, and round flanges(12a,12b) formed integrally at both sides of the core. The gap is formed between the end of the threaded part and the flange to automatically arrange the wire in the end of the threaded part, and is less than the diameter of the wire. The flanges are bent to the core about 0.3-1.7 angular degrees in due consideration of the pressure applying to both flanges of the core by the winding tension of the wire in winding the wire on the spool bobbin. The tension is applied to the bent portions of the flanges in winding the wire, and the winding layer is perpendicular to the inner faces of the flanges to prevent the wire from being omitted in the upper part of the winding layer.
