Abstract

Procédé et installation pour la production en continu de profilés hélicoïdaux en matériaux composites. Il comprend un ensemble de mandrins cylindriques avec usinage en hélice dont la gravure permet le vissage dans une filière fixe servant d'écrou. La rotation étant assurée par un système de serrage du mandrin permettant une libre translation. Le profilé se formant dans l'espace du filetage restant libre, par tirage de fibres à hautes caractéristiques imprégnées d'une matrice se solidifiant par réticulation ou refroidissement. La présente invention peut être utilisée pour la fabrication de ressorts hélicoïdaux de traction ou de compression notamment pour l'automobile et l'industrie spatiale.
