Abstract

Abstract Translated from French L'invention concerne les structures tissées creuses. Elle a pour objet un procédé et une machine permettant de réaliser des armatures creuses de révolution par tissage à trois dimensions de baguettes 11, de fils circonférentiels 12 et de fils radiaux 13. Dans le réseau de baguettes 11 mis en rotation autour de l'axe 16 sont introduits et tissés les fils 12 et 13, ces derniers étant tricotés par une aiguille 28 sous forme de chaînette, et les couches hélicoïdales de fils ainsi formées, reposant sur un plateau 20 animé d'un mouvement descendant progressif, glissent le long des baguettes 11 et sont tassées par des doigts 30 surmontés d'un plateau de pression 38. Application à la réalisation d'armatures tissées de forme complexe pour corps creux de révolution en matière plastique. The invention relates to hollow woven structures. It relates to a method and a machine making it possible to produce hollow reinforcements of revolution by weaving in three dimensions of rods 11, of circumferential wires 12 and of radial wires 13. In the network of rods 11 rotated around the axis 16 are introduced and woven the threads 12 and 13, the latter being knitted by a needle 28 in the form of a chain, and the helical layers of threads thus formed, resting on a plate 20 driven by a progressive downward movement, slide along the rods 11 and are compressed by fingers 30 surmounted by a pressure plate 38. Application to the production of woven reinforcements of complex shape for hollow bodies of revolution made of plastic.
