ABSTRACT:
The automatic winding of extremely small electrical core coils, for example video core coils, takes place on a rotatable winding unit which cooperates with a wire drawing apparatus provided with a catch hook. Each coil former receiver is provided with an associated wire mount. During the winding, the coil former together with the coil former receiver is immobile wherein the wire section of the winding wire necessary for each core coil is drawn from a wire storage coil over a wire deflector. During the winding of the core coil the rotatable winding unit, together with a plurality of wire retainers arranged in a vertically adjustable winding head, can be positioned so that the catch hook passes horizontally not only through one of the wire retainers but also through the core opening in the coil former. After applying the winding wire to one limb of the coil former during the withdrawal of the catch hook through the core opening, the cyclic rotation of the wire retainers then takes place through 270.degree. whereupon a complete turn is formed.
