ABSTRACT:
In a double-ring winding machine for winding of wire on closed core members such as toroidal cores comprising a wire magazine and an annular wire advancing member arranged concentrically to rotate about the same axis independent of each other, the wire magazine has an internal diameter exceeding the external diameter of the wire advancing member and the wire magazine and the wire advancing member are suspended in mutual radial alignment throughout their axial width. Wire is drawn out from the wire magazine through a bottom slit and guided through a hole in the wire advancing member during rotation of both and simultaneously wire is filled into the magazine through an opening in the external side thereof. The filling opening may have the form of a slit opposite the bottom slit whereby the wire magazine may be composed of two rings of semi-circular cross-section separated by the bottom and filling slits only, both of which may be wave-formed in the longitudinal direction.
