Abstract: A device for manufacturing and inserting single-turn coils into the magnetic core slots of electrical machines comprises a mechanism for cutting off pieces of a wire conductor, a mechanism for bending the wire and shaping a loop, at least one mechanism for retaining and orienting coils made of concentrically arranged external and internal cylinders capable of rotating with respect to each other and having slots for accommodating the coils, said mechanism being made in the form of a detachable satellite with elements for fixing its position with respect to the working members of said mechanisms, a mechanism for moving apart the coils, a mechanism for transferring the set of coils, a mechanism for returning the cylinder to their initial position, a storing element, mechanisms for pressing-in the set of coils and for moving apart the ends of the coils at the commutator side, and transport mechanisms.The device can be used, for example, for making the armatures of automobile starters.
