Longitudinally Moving Shed Patents (Class 139/460)
  • Patent number: 9447530
    Abstract: The present invention pertains inter alia to a method for producing a component for connecting structures at crossing regions thereof, having the following steps: depositing first and second fibers on an underlay in such a way that a respective first fiber has an offset in the longitudinal direction of the first or second fiber with respect to a respective second fiber; connecting the first and second fiber along an overlap region, in which the first and second fibers overlap; and pivoting the first and second fibers with respect to one another to form the component.

  • Patent number: 6953067
    Abstract: In order to deflect a warp thread sheet (2) in a weaving machine, a deflecting device (18)is provided which is guided in guides (26) that also guide heald frames (13, 14, 15, 16). The deflecting device positions a segment (46) of the warp thread sheet (2) that starts at a beatup line (7) of the fabric (8) between the beatup line and the heald frames.

  • Patent number: 5174341
    Abstract: The traversing shed loom has a shedding weaving rotor into which weft yarns are picked. The rotor has shedding elements and beating-up combs in which warp placing guides place warn yarns by moving transversely to the direction of rotor rotation. Most of the warp yarns are deflected transversely to the direction of rotation during shedding and the deflection is cancelled only by the shedding elements moving away before the beating-up of the weft so that the warp yarns are realigned. The beating-up combs have at least two warp yarns per occupied space. The position of guides, the geometry and position of the combs, the position of top shed guides and bottom shed guides and the warp yarn placing program are so adapted to one another that the streakiness, i.e., warp streakiness, is controllable.

  • Patent number: 4887650
    Abstract: A beat-up mechanism for a weaving loom includes a relatively movable indexing reed and beat-up reed adjacent each other and arranged to transport weft threads adjacent the fell of the fabric and then beat-up the weft threads into the fell by means of beat-up fingers inserted between warp threads. The indexing and beat-up reeds each are constructed as modular units and include multiple, parallel fingers having narrow tip portions and wider root portions, whereby the wider root portions of one reed maintain the warp threads spaced apart for insertion of the tip portions of the other reed during weft transfer. The indexing and beat-up reeds are particularly useful in a multi-shed weaving loom wherein multiple sheds are progressively moved toward the fell of the fabric during the weaving operation with insertion of a pick in each shed. The indexing and beat-up reeds, moreover, include a guiding arrangement whereby the reeds are positively maintained in lateral alignment during weft transfer and beat-up.
