The invention relates to a method for producing a multi-phase winding (83) for a stator of an electric machine by means of a winding device (90). For this purpose, a semi-finished winding product (50) is produced and, in the production of the semi-finished winding product (50), a plurality of phases of the winding (83) are produced and, in the process, two half windings (119, 120, 121, 122, 123, 124) connected electrically in series are produced for each phase of the winding. Each half winding (119, 120, 121, 122, 123, 124) is produced in the form of a winding star by means of winding sub-groups as waves having wave sides (133). The method is characterized in that the half windings (119, 120, 121, 122, 123, 124) of the phases are arranged in a stack in such a way that, in a stacking direction, a first half winding (124) of a first phase is followed directly by a first half winding (122) of another phase and said first half winding of the other phase is followed by a first half winding (120) of a further phase and a first sub-stack is formed by the first half windings (120, 122, 124), a second sub-stack being formed on the first sub-stack in the same stacking direction and a second half winding (123) of the first phase being wound and a second half winding (121) of the other phase being wound directly on the second half winding of the first phase and a second half winding (119) of the further phase being wound directly on the second half winding (121) of the other phase.
