Abstract: A sub-assembly is disclosed. The sub-assembly is a valve including: a housing, a plunger, a seal, an indexing member, a biasing member, a seat member and a push button actuator. The plunger axially supports the seal and the indexing member within the housing. The biasing member is supported by the seat member and axially biases the plunger relative the housing in a first axial direction in order to axially bias the seal in the first axial direction toward a sealing surface formed by the housing. Arrangement of the seal adjacent the sealing surface formed by the housing prevents fluid flow through the valve. When the seal is arranged adjacent the sealing surface formed by the housing, a distal camming surface of the indexing member is not registered adjacent a corresponding camming surface of the housing.

Abstract: In various embodiments, the present disclosure relates generally to a method for needling a spiral textile to create a needled preform, the method comprising receiving the spiral textile on a bed plate of a circular needle loom, engaging a positional structure of the spiral textile, rotating the spiral textile around the circular needle loom, depositing a predetermined number of layers of the spiral textile on the bed plate, and needling the spiral textile to create the needled preform. Moreover, the present disclosure also provides, in various embodiments, a method for creating a circular needled preform from a spiral textile, comprising attaching sacrificial fibers to at least one of the weft tow and the plurality of warp tows proximate at least one of the inside diameter and the outside diameter, and engaging the sacrificial fibers with an engagement mechanism on a circular needle loom.

Abstract: A fiber reinforcing texture (10) woven as a single part for fabricating a composite material part having an inner portion (12), or core, made by three-dimensional weaving with yarns made up from discontinuous fibers, and a portion (14, 16) adjacent to an outside surface, or skin, made by weaving with yarns made up from continuous filaments.

Abstract: An air bag material and a process for making the material are disclosed. The air bag material is formed from a water jet woven fabric containing warp yarns and weft yarns. In accordance with the present disclosure, the warp yarns are treated with a size composition prior to being woven into the fabric. The size composition improves the runnability of the yarns. Of particular advantage, the size composition does not need to be removed after the fabric is produced. In fact, leaving the size composition on the fabric has been found to significantly increase the tear strength of the fabric.

Abstract: A substrate including a plurality of monofilaments, or a combination of monofilaments and multi-filament yarns oriented in perpendicular directions, has a tendency to curl around a central space. When all monofilaments are used, the monofilaments along one direction may have a larger diameter than the monofilaments along the other direction. The monofilaments are woven such that the larger diameter monofilaments form floats predominantly on one side of the substrate. For the monofilament-multifilament combination the monofilaments form floats predominantly on one side of the substrate. The substrate curls about an axis parallel to the monofilaments forming the floats. The side having the floats faces outwardly away form the central space. Preferably, the monofilaments are orientated in the warp direction along the substrate. The filaments may be woven in a herringbone twill weave, a double cloth herringbone twill weave or a satin weave to provide the floats.

Abstract: In a fabric to assist a vehicle to run in the presence of snow, sand, or mud, or in an unleveled land, a core fabric is formed by weaving the weft and the warp. An upper convexity warp which is disposed over the core fabric forming warp and is woven with an upper convexity weft disposed on the core fabric forming weft, and/or a lower convexity warp which is disposed under the core fabric forming warp and is woven with a lower convexity weft disposed under the core fabric forming weft, to form a convexity. The upper or lower convexity warp is woven with one or plurality of the core fabric forming wefts to form a woven portion.

Abstract: The invention relates to a device for producing a tape having a curve, especially a curved flat line compound. The inventive device consists of several clamping jaw pairs that are arranged downstream in relation to a weaving device and serve for withdrawing the individual lines. The clamping jaw pairs are moveably arranged along the direction of withdrawal, are driven and can be swivelled. In a preferred embodiment, two clamping jaw pairs are used which can be moved to-and-fro along the direction of withdrawal in an alternating manner and by means of drives that engage on the ends of the clamping jaws. The amplitude of the movement can be changed in an independent manner on both sides. The drive device can be configured as a crank gear system. A crank gear engages on each side of each clamping jaw and the lifting movement of the crank gears of one side can be adjusted in relation to the lifting movement of the crank gears on the remaining side. Different warp threads (e.g.

Abstract: A weaving method and apparatus for producing a length of fabric which has a variable width, wherein the sheet of warp threads is guided in the area of the shed with a space between the warp ends which is enlarged or reduced according to the desired width of the fabric. The fabric is guided by a spreader device (19) at least on both of its longitudinal edges and preferably directly after the stroke of the weft yarn. The effect of the spreader devices on the width of the fabric is controlled synchronously with and substantially proportional to the enlargement (spread) and reduction (contraction) of the space between the warp ends. Seamless and seamed tubes with variable diameters can be produced using the inventive method.

Abstract: This invention discloses woven materials in which the constructed woven materials have a myriad of desired two- and three-dimensional shapes. The invention specifically discloses woven materials that are constructed by continuously varying the density and/or direction of the warp and/or weft fibers or yarns, as well as their angle of contact, at will during the mechanical weaving process. These two- and three-dimensional woven materials can also be used as reinforcers of variously shaped flexible or rigid composite materials.
