The present invention relates to a method and to a device for the automated manufacture of at least one elongate composite material part with one or layers. According to the invention, the method is characterized in that it consists of depositing, by unrolling onto the elongate mold (3) in a first predetermined direction along the mold (3), a first composite material (RM) layer attached to a substrate tape (RS) that is separable from the first layer, and forming and compacting part of this assembly onto the mold (3) in the first direction so as to partially shape it to the shape of the mold, and then forming and compacting the remaining portion of the substrate tape (RS) assembly and composite material (RM) first layer in a second direction opposite the first direction so as to shape it completely to the shape of the mold (3) and separating, by peeling, the substrate tape (RS) from the composite material (RM) first layer that is secured to the mold (3) by unrolling the substrate tape (RS) again in the second direction. The invention can be used in the field of aeronautics.

La présente invention concerne un procédé et dispositif de fabrication automatisée d'au moins une pièce allongée à une ou plusieurs couches en matériaux composites. Selon l'invention, le procédé est caractérisé en ce qu'il consiste à déposer, par déroulement sur le moule allongé (3) suivant une première direction prédéterminée le long du moule (3), une première couche d'un matériau composite (RM) accolée à un ruban de support (RS) séparable de la première couche et à former et compacter suivant la première direction une partie de cet ensemble sur le moule (3) a fin de le conformer partiellement à la forme du moule, former et compacter suivant une seconde direction opposée à la première direction la partie restante de l'ensemble à ruban de support (RS) et première couche de matériau composite (RM) afin de le conformer complètement à la forme du moule (3) et séparer par pelage le ruban de support (RS) de la première couche de matériau composite (RM) solidarisée au moule (3) par réenroulement du ruban de support (RS) suivant la seconde direction. L'invention trouve application dans le domaine de l'aéronautique.
