  • Patent number: 4621490
    Abstract: A method and an apparatus for producing a fasciated yarn, utilizing an air nozzle for false-twisting a fiber bundle. The apparatus is provided with a fiber passage comprising an inlet portion, a small channel, and a large channel, and is provided also with a contact area on an inner wall of the small channel, this contact area being formed by the intersection at an angle of the small channel and the large channel.During the spinning operation, the fiber bundle is forced against the contact area, effectively suppressing a twist imparted by a vortex such that it does not ascend toward the upstream region.Also, since ballooning can be suppressed by the contact area, the size of the small channel can be increased, resulting in the intake by suction of a sufficient amount of air in the inlet portion.

  • Patent number: 4450678
    Abstract: An air nozzle, suitable for producing a fasciated yarn, having at least one jet in each of narrow and wide passages along the traveling direction of the fiber bundle. Each jet is directed to generate a vortex whirling reversely from that of the other passage. The twist imparted to the fiber bundle by the vortex generated in the wide passage is restrained by the vortex whirling reversely thereto in the narrow passage. As a result, circumferential fibers of the fiber bundle are less twisted relative to the core portion thereof. During the untwisting operation of the vortex of the wide passage, the circumferential fibers are entangled around the core portion with a twist corresponding to the difference from the core portion, thereby obtaining a well-fasciated yarn.

  • Patent number: 4434611
    Abstract: The present invention relates to a pneumatic twisting spinning apparatus comprising a drafting device for forming a fleece, a deflection roller, a pneumatic twisting nozzle for injecting air into a twisting tube to form a swirling air stream, so that the fleece can be twisted into a yarn, a take-up roller for withdrawing the yarn, and a winding roller. The deflection roller is disposed adjacent to the front roller, for varying the direction of fleece travel and supplying the fleece along an outer peripheral wall of said front roller, and separating ends of peripheral fibers from the fleece as free fibers, which will be twisted by the pneumatic twisting nozzle so as to be wound around central main fibers, thereby forming a bundled yarn.
