  • Patent number: 6712099
    Abstract: A three-dimensional weave architecture for weaving preforms has fill fibers woven to provide layer-to-layer interlocking of layers of warp fiber as well as interlocking of fibers within each layer. The woven preform transfers out-of-plane loading through directed fibers to minimize inter-laminar tension. The preform has a base and at least one leg extending from the base, the base and leg each having at least two layers of warp fibers. The fill fibers follow a weave sequence which carries them through part of the base, then into the legs, then through the other portion of the base, and back through the base to return to the starting point of the fill tow. The leg may be connected at a single- or distributed-column intersection, and the intersection may be radiussed. The outer ends of the base and legs may have tapers formed from terminating layers of warp fibers in a stepped pattern.

  • Patent number: 6478055
    Abstract: A pulley-less shed-forming device for a weaving machine, such as a jacquard machine, has a number of shed-forming elements (1), such as hooks, to determine the positions of one or more warp yarns on a weaving machine. A lifting device (50), (51) moves the shed-forming elements (1) up and down. At least one actuator (40)-(44), (80), (83) is provided for selectively influencing the shed-forming element (1), so that it is either kept at a fixed height, or is moved by means of the lifting device (50), (51). The element (1) has at least one selection body (7), (8), (9) which, for said selective influencing, may be moved into first or second stable positions, as desired, by an actuator (40)-(44), (80), (83) forming a shed-forming element (1) in itself. It may also be formed as a device without a pulley. Because the positions of the selection body are stable, their position may be changed by a single temporal influence by the actuator making the device energy efficient.

  • Patent number: 6470917
    Abstract: A tack-in apparatus is provided wherein injection ports are arranged at upper and lower sides of a weft yarn path, respectively. The injection ports inject currents for folding back an end portion of a cut weft yarn into a warp yarn opening on the weft yarn path which the weft yarn passes by a beating operation. Air guides projecting toward the warp yarn opening are formed at circumferential portions of the injection ports between the weft yarn path and the injection ports. The surfaces of the air guides which are on the sides of the injection ports are inclined toward the weft yarn path at front end portions of the air guides. In order to tack in the weft yarn end, the injection air currents are directed to the central portion of the warp yarn opening. This enables the weft yarn end to be transferred reliably, the tack-in operation to be carried out reliably, and the turbulence of the warp yarn to be reduced.
