漸増させたことを特徴とするコイリング装置。 As a coil spring wire, a wire having a substantially oval cross section with asymmetrical both sides in the long diameter direction and a torsion regulating surface at one end on the long diameter side of the cross section is used. When manufacturing a coil spring by coiling so that the wire crosses the coil axis, a pair of supply rollers that feed the wire in one direction and a pair of supply rollers that feed the wire in one direction, and the wire fed by the pair of supply rollers are inserted and guided. a tip guide mold having a guide hole having a cross-sectional shape similar to the cross-sectional shape of the wire; a coiling member disposed near the tip guide mold to coil the wire passing through the guide hole; a pitch tool for moving the coil formed by the coiling member in the coil axial direction; The coiling member includes a second roller having a guide groove that slides against the convex arc surface on the side opposite to the twist regulating surface, and the coiling member includes a pressing body having a guide groove that slides against the twist regulating surface of the strand. , a receiving member having a guide groove that slides against the convex arc surface side of the strand, and the guide hole is adapted to the twist-restricting surface of the strand, so that the strand is twisted in a direction opposite to the twisting direction during coiling. In a coiling device in which the long axis extension of the guide hole is inclined with respect to a straight line parallel to the coil axis to give a twist in the direction, the long axis extension of the guide hole has an inclination angle. An inclination in the same direction as the major axis extension line of the guide hole, on the major axis extension line of the virtual element wire cross section defined by the groove and the major axis extension line of the virtual element wire cross section defined by both guide grooves of the coiling member. A coiling device characterized in that the coiling device has an angle, and the inclination angle of each major axis extension line is gradually increased in the order of the supply roller pair, the tip guide type, and the coiling member.
