ABSTRACT:
The invention relates to woven hollow structures.
Its object is to provide a method and a machine making it possible to obtain hollow reinforcements of revolution by three-dimensional weaving using rods 11, circumferential yarns 12 and radial yarns 13. In the network of rods 11 made to rotate around the axis 16 are introduced and woven the yarns 12 and 13, the latter being knitted by a needle 28 in the form of a chain stitch, and the helical layers of yarns thus formed, resting on a plate 20 to which is imparted a progressive downward movement, slide along the rods 11 and are tamped by fingers 30 over which is mounted a pressure plate 38.
Application to the fabrication of woven reinforcements of complex shape for hollow bodies of revolution in plastic material.
