Abstract: A method of weaving a spiral-shaped textile includes inserting in the vicinity of the fell of the textile a finger adjacent to a first intermediate warp fiber between a first edge and a second edge; forming a loop around the finger with the weft fiber; wrapping weft fiber around the first intermediate warp fiber between the first edge and the second edge of the textile to secure the weft fiber in a radial direction between the first edge and the second edge of the textile; extending the weft fiber to the first edge of the textile; securing the weft fiber using a knitting system on the first edge of the textile; and removing the finger from the textile.

Abstract: The invention concerns the production of deformable hollow reinforcements of revolution by a three-dimensional weaving. In a network of rods 18 held and rotated about a vertical axis 11 by rotary perforated plates 52, 53, 54, there are inserted in oblique crossed directions, i.e. non-radial directions, threads in the form of chain stitch loops produced by a knitting device 32. The chain stitches are downwardly compacted by the lower edge of the plate 52 which is inclined for this purpose.

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.
