Abstract
A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape. Accordingly, bending accuracy in the three-dimensional shape for the round metallic wire is improved.
