Abstract

L'invention concerne un élément (38) longitudinal pour un moule (10) d'injection destiné d'une part à recevoir une préforme (12) tissée de direction principale déterminée (X) comportant au moins un bord (18) s'étendant sensiblement suivant ladite direction principale, et d'autre part à permettre l'imprégnation de ladite préforme (12) par une résine injectée dans ledit moule, caractérisé en ce que ledit élément (38) est amovible, adapté à la préforme et conformé en profilé, et destiné à être agencé dans ledit moule (10) le long d'au moins ledit segment (19) dudit bord (18) de la préforme (12) pour éviter le pincement de fibres libres (21) s'étendant à partir dudit bord (18) de la préforme entre lesdites deux parties (22, 24) dudit moule (10). L'invention concerne un moule (10) comportant un tel élément (38) et un procédé de fabrication utilisant ce moule (10.)
