A method of forming, on a strip-shaped laminate of multiple reinforcing fiber sheets superimposed one upon another, two flexures with respect to the cross-section configuration thereof, wherein in the forming of the two flexures with the use of two flexure forming dies independent from each other, respectively, the two flexure forming dies are arranged so that the relative distance of the two flexure forming dies is changeable in the direction perpendicular to the longitudinal direction of the strip-shaped laminate. This method can be effectively utilized in the production of a reinforcing fiber molding with changing of the distance between the two flexures, namely, width of web portion or gauge between two flange portions from the strip-shaped laminate, or the production of fiber reinforced resin (FRP) molding therefrom.

L'invention concerne un procédé de formation, sur un stratifié en forme de bande composé de multiples feuilles de fibre de renfort superposées les unes sur les autres, de deux flexions par rapport à la configuration en coupe transversale de celui-ci. Lors de la formation des deux flexions à l'aide de deux filières de formation de flexion indépendantes l'une de l'autre, respectivement, les deux filières de formation de flexion sont placées de sorte que la distance relative des deux filières de formation de flexion peut être modifiée dans la direction perpendiculaire à la direction longitudinale du stratifié en forme de bande. Ce procédé peut être utilisé de manière efficace dans la production d'un moulage de fibre de renfort en modifiant la distance entre les deux flexions, plus précisément, la largeur de partie de bande ou de calibre entre deux parties brides du stratifié en forme de bande, ou la production d'un moulage en résine renforcée de fibre (FRR) à partir dudit moulage de fibre de renfort.
