Abstract (en)
[origin: ES8305151A1] Method of forming windings on a closed core, preferably a ring core, for electric coils which includes guiding by action of a magnetic field a magnetizable needle fastened to a starting end of a winding wire along a closed continuous travel path extending partly through an aperture in the core so as to wind the winding wire on the core, the closed continuous travel path decreasing in length with duration of winding of the winding wire on the core.
