Abstract
A method and device for manufacturing winding mats for manufacturing a coil winding of an electric machine. The winding mat is composed of wave winding wires bent as a flat winding in one plane. To be able to manufacture different coil mats with improved electrical characteristics easily and reliably in large series, it is proposed not to interlace or twist the wave winding wires, but to plug them at least partially. In addition, a method and a device for manufacturing a coil mat from several winding mats designed as individual mats are proposed. The device preferably comprises an offsetting device for introducing height offsets into winding heads of the wave winding wires.
