    摘要： A filament winding apparatus includes: N guide members arranged around a liner having an elongate shape such that the N guide members are centered around a center axis of the liner, the center axis extending in a longitudinal direction of the liner, each of the N guide members being configured to supply one bundle of fibers, and N being an integer equal to or larger than two, a drive unit configured to repeat, W times, a winding operation to helically wind N bundles of fibers supplied respectively from the N guide members around the liner at the same winding angle to form a reinforcing layer, the winding operation being an operation in which each of the N guide members travels, in a direction parallel to the center axis of the liner, from and back to a winding start position, and W being an integer equal to or larger than two.

    摘要： A filament winding device includes a supporter configured to support a liner in a rotatable manner; a yarn supplying unit configured to support bobbins; a helical winding head configured to helical-wind a fiber bundles onto the liner; and a standard thread guiding mechanism configured to form a standard thread guide channel that guides a standard thread from the bobbins to the liner, the standard thread being different from the fiber bundles and being connected to leading ends of the fiber bundles, the standard thread guiding mechanism including nozzles configured to blow the standard thread with a compressed gas, and guide tubes configured to guide the standard thread blown by the nozzles, and the nozzles and the guide tubes being disposed along a fiber bundle guide channel, and capable of taking up the standard thread from the standard thread guide channel to the fiber bundle guide channel.

    摘要： Yarn delivery device for a twisting or cabling machine, for feeding a yarn via a traversing yarn guide to a take-up package, the yarn delivery device having a first deflection roller for deflecting a yarn; a driven godet, arranged downstream of first deflection roller in yarn transport direction; a separator roller, arranged relative to the godet such that a yarn can be laid several times around the separator roller and the godet, said yarn being wrapped around separator roller and godet jointly; and a pitch lever, having a second deflection roller arranged downstream of godet in the yarn transport direction, for deflecting the yarn again. A cantilever, having a third deflection roller, which, in the yarn transport direction, is arranged downstream of the second deflection roller and upstream of traversing yarn guide for feeding the yarn onto a take-up package, the second deflection roller being arranged on a different side of a vertical plane extending through axis of rotation of the separator roller from the third deflection roller to receive the yarn from separator roller or godet and to deflect the yarn toward third deflection roller.
