The invention relates to a method and device for forming wave windings, comprising web sections that are interconnected by winding heads, and introducing said windings into rotor or stator cores of electric machines. The wave windings (10) are cut from a continuously formed wave winding strip (52) consisting of winding wire (56), which is laid alternately around the external lateral surfaces of forming projections (50) by a wire guide (54) during the forming process. Said projections are offset in relation to one another on the periphery of two axially adjacent rotating discs (46, 48). Whilst the wave winding strip (52) is entrained on the periphery of the discs (46, 48), the distance between a forming projection (50) in the first row and the following forming projection in the other row is increased, in such a way that the external lateral surfaces of the forming projections (50) form the winding heads (14) of the wave windings (10). The wave windings (10) that have been cut from the wave winding strip (52) are subsequently introduced into grooves (89) of a rotor or stator core, or a transmission tool (88) that is similar to a rotor, said grooves opening radially to the exterior. |
