ABSTRACT:
A stator or rotor for electrical machines is described whose winding overhangs are in each case bound with a single thread at one end, the intertwinings of all the loops formed from the thread being situated at the radially internal side of the winding overhangs. In the method proposed for producing such a stator or rotor, thread loops are drawn from radially outside alternately through below the winding overhangs and over the winding overhangs, and then intertwined at the radially internal sides of these, in that through each loop there is drawn the loop formed next. An apparatus suitable for carrying out this method has a needle with an eye at the forward end, which is taken alternately under and over the winding overhangs in the radial direction into the working region of a hook which is adapted to be moved rectilinearly and axially at the radially internal side of the winding overhangs.
