摘要

A process for the preparation of a hollow shaft with at least one integral flange made of fiber composite material, in which– a plurality of intersecting windings (13) made of fiber material onto a core (20) are applied, the inner contour of a shaft section (11), wherein the core (20) for each flange (12) a radial expanding ring (22) with an axial bearing surface (24) for presetting the form of a front wall of a flange (12) comprises,– the windings (13) via an outer circumferential portion (23) of the respective expanding ring (22) are placed and fixed, and– after completion of the windings (13) the fixing of the wound fiber material is released and by means of a scraper means (30) sections of the windings (13) from the outer peripheral portion (23) of the spreader ring (22) over an edge (25) and drawn off against the axial bearing surface (24) of the same are brought into contact, in order to obtain a partial section of a flange (12) to form.
