Patent number: 6926588Abstract: The invention relates to a method of manufacturing a band coil by means of a material-removing process performed on the coils so as to obtain a band coil which has a profile in the direction of the coil axis. Such a process may be a discharge process, an etching process or a mechanical grinding process.
