A process and a device for producing self-supporting saddle coils (96), where first, a winding receiver (10), which has a base (11) and a cutout (13), is produced to form saddle coils (46). Segments (12) can be attached to the inside contour of the cutout (13). These segments (12) are spaced with respect to each other. These spaces, also called slots (14), serve to receive wires running in the Z-direction. The constructed length of the segments (12) is such, that their ends extend beyond the base (11), thus forming the chambers (16.u, 16.o) between the edges (15.o, 15.u) and the ends of segments (12) that curve away from the centerline. This winding receiver (10) is wrapped by a winding device (21), which wraps the wire in the slots (14) and the chambers (16.u, 16.o). When the winding pass of saddle coil (46) is formed, the wrapping wire (32), covered with thermoplastic material, is heated so that the windings of the wrapping wire (32) are bonded to each other, after cooling. The segments (12) are then removed from the cutout (13) and the finish-baked saddle coil (46) can be pulled out of the cutout (13).
