Apparatus and methods are presented for forming coils that are used for the winding of a stator of a dynamo-electric machine and for inserting those coils into slots of the stator. The apparatus includes a plurality of coiling stations that operate in a synchronously staggered manner and an inserting station. The coiling and inserting stations are equiangularly spaced apart from each other around a transfer station.

Why it's free to use
- Filed June 27, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
