Abstract
Coils are manually inserted into respective guide paths of a coil inserting jig which is placed with respect to an advancing mechanism. A coil advancing pusher is movably located inside the jig to move the inner portions of the coils toward a core structure mounted on the jig. A coil holding device is provided externally of the jig for engaging the outer portions of the coils when the inner coil portions are initially advanced toward the core structure. The inner coil pusher and the outer coil holding device are simultaneously moved by the advancing mechanism for coaction with each other to advance the inner and outer coil portions toward the core structure with the coil orientations substantially aligned with the grooves of the core structure to ensure smooth insertion of the coils respectively into the core grooves.
