Abstract

Abstract Translated from French L'invention concerne un procédé de fabrication de pièces de révolution en matériau tridimensionnel, ainsi qu'une machine pour la mise en oeuvre de ce procédé. The invention relates to a method of manufacturing parts of revolution in three-dimensional material, as well as a machine for carrying out this method. Des couches de fils superposées sont réalisées par bobinage et par tramage sur un mandrin (12) muni de picots (14), de telle sorte que certains des fils de trame ne s'étendent pas sur toute la longueur du mandrin (12). L'extrémité de ces fils de trame est maintenue provisoirement au moyen de deux organes rétractables (62, 88), puis en enroulant un fil de maintien (100). Layers of superimposed threads are produced by winding and wefting on a mandrel (12) provided with pins (14), so that some of the weft threads do not extend over the entire length of the mandrel (12). The end of these weft threads is temporarily maintained by means of two retractable members (62, 88), then by winding a retaining thread (100). Application à la réalisation de pièces dont la densité, uniforme ou non, peut être parfaitement contrôlée . Application to the production of parts whose density, uniform or not, can be perfectly controlled.
