ABSTRACT:
In a machine for winding and inserting coils of the type wherein a flier is rotated so as to wind the conductor drawn from the flier around two blades of an insertion tooling and an auxiliary plate located radially outwardly of said two blades and spaced apart therefrom by a predetermined distance, thereby forming a coil which is directly inserted together with a wedge into slots of a magnetic core of a rotary electric machine, an improvement wherein the blades with wedge guides which form the insertion tooling are divided into alternating main and auxiliary blades equiangularly spaced apart from each other, the auxiliary blades being axially movable relative to said main blades in such a way that when the conductor is wound around a bobbin formed by two of the main blades and an auxiliary plate, the auxiliary blades are retracted away from the main blades, but when the wound coils are inserted into the slots of the magnetic core, the auxiliary blades are raised to align with the main blades, thus forming the insertion tooling. In addition, all the coils for one phase may be continuously wound so as to have only one starting lead and one finishing lead.
