    • An edgewise winding apparatus (10) is arranged to produce a coil (12) by winding a wire (15). The coil (12) includes a plurality of bent portions (12c) having equal bending angles and unbent portions (12a, 12b) each existing between the bent portions (12c). The apparatus includes a holding shaft (67) which will contact with an inner periphery surface (15a) of a flat wire (15) and clamp one of the bent portions (12c) in a thickness direction of the flat wire (15) and bending jigs (77) which will contact with an outer periphery surface (15b) of the flat wire (15) and rotate while pressing the flat wire (15) in cooperation with the holding shaft (67) to bend the flat wire (15) to form the bent portion (12c). The bending jigs (77) are configured to move forward and backward in a lamination direction of the flat wire (15). The bending jigs are arranged in number equal to the number of bent portions (12c) or unbent portions (12a, 12b) of the coil (12) so that the bending jigs are placed at equal angular intervals around the holding shaft (67) so as to rotate around the holding shaft (67).
    • 沿边卷绕装置(10)被布置成通过缠绕线(15)来产生线圈(12)。 线圈(12)包括具有相同弯曲角度的多个弯曲部分(12c)和每个存在于弯曲部分(12c)之间的未弯曲部分(12a,12b)。 该装置包括:保持轴(67),其将与扁平线(15)的内周面(15a)接触,并且在扁平线(15)的厚度方向上夹紧弯曲部(12c)中的一个,并弯曲 与扁平丝(15)的外周面(15b)接触并且与保持轴(67)协作地按压扁平丝(15)而旋转的夹具(77)将扁平线(15)弯曲成 形成弯曲部分(12c)。 弯曲夹具(77)构造成沿扁平丝(15)的层叠方向前后移动。 弯曲夹具的数量等于线圈(12)的弯曲部分(12c)或未弯曲部分(12a,12b)的数量,使得弯曲夹具围绕保持轴(67)以相等的角度间隔放置,因此 以围绕保持轴(67)旋转。
