Abstract (en)

[origin: DE19909026A1] The invention relates to a method and a device for producing coils in the form of a wave winding for electrical machines. An essentially round and polygonal coil (54) is produced on a winding template (10). Said coil (54) is stripped from the winding template (10) by means of strippers (56). The coil (54) is then deformed into a wave winding by means of a form tool (12) and using radial deformation. The coil is then transmitted to a transmission or pull-in tool (14). The aim of the invention is to produce wave windings with simple means, on a small area and with very short clock time. To this end, the form tool (12) is arranged axially adjacent to the winding template (10) on the rotational axis thereof.
