ABSTRACT:
An improved apparatus for producing coils for electrical machines of the type wherein the wire windings are formed on a coil winding body in the form of a slide core by means of flyers which are rotated relative to the coil winding bodies, so that the major portion of the wire windings are pushed, during the winding process, onto a coil holder which is in engagement with the slide core. The apparatus is provided with a plurality of adjacent slide cores, which are jointly in engagement with the same coil holder during the winding process and which are each provided with a respective flyer. The rotational movements of the individual flyers about the associated slide cores are controlled to be in synchronism with one another during the winding process, whereby a plurality of coils of the complete winding may be simultaneously wound.
