Zusammenfassung:Method of manufacturing "T" shaped stringers (1) with an angle different from 90° between the web (2) and the foot (3) whereby the "T" shaped stringers have a stringer web and a stringer foot. The method comprises, after placing together two hot-formed "L" shaped semi-stringers to form a "T" shaped stringer, placing the "T" shaped stringer inside an invar alloy angle leaving a gap between the stringer web and the invar alloy angle. Afterwards, a heating device (7) is moved over the stringer feet (3) surface and a roller (8) slides over said stringer feet (3) surface to adapt the geometry of the stringer feet to the geometry of the invar alloy angle. The resulting "T" shaped stringer is co-bonded on a cured skin with an adhesive line between the stringer and the cured skin, and finally the obtained "T" shaped stringer is cured.
