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.

Abstract: A cylindrical net body using helical wire members that can be easily assembled and disassembled at a working site. The invention provides also a cylindrical net body using helical wire members that have high tenacity and high durability and yet can reduce the weight. Wire members having a predetermined outer diameter are wound in predetermined lead and predetermined pitch to provide helical wire members in such a fashion that a diameter of a helix is about twice the outer diameter of the wire members, crests and troughs have substantially a similar shape, and each trough is positioned outside the center of the helix. The helical wire members are wound into a coil shape to form transverse helical wire members. Longitudinal helical wire members formed of the helical wire members are united and fixed side by side with the transverse helical wire members, with predetermined gaps, to form a cylindrical net body.

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 composite forming fabric woven to a repeating pattern in at least 6 sheds; up to at least 36 sheds can be used. All of the paper side layer warp yarns are pairs of intrinsic warp binder yarns (101, 102) occupying an unbroken warp path in the paper side surface including three segments. The first and a second are occupied in turn by each intrinsic warp binder yarn (101, 102), and the third by both intrinsic warp binder yarns (101, 102) of a pair. The first, second and third segments are separated by at least one paper side layer weft, and a first or second segment is adjacent each end of the third segment. Within each first and second segment, each intrinsic warp binder yarn (101, 102) also interlaces once with a machine side layer weft (2′, 9′), at the same point as a machine side layer warp (103) interlaces with the same weft (2′, 9′). The weave path occupied by each member of a pair of intrinsic warp binder yarns (101, 102) can be the same or different.

Abstract: A press fabric for a pulp machine is a weft-abrading type fabric manufactured by weaving a warp monofilament and a bundled yarn. The bundled yarn has fine water-sucking spaces formed between raw filaments of a small diameter by bundling up the raw filaments. Monofilaments may also be used as the wefts in combination with the bundled yarns. The bundled yarn forms the most protuberant crimp to the surface of the fabric which results in improved water-sucking ability, washing ability, showering resistance, and abrasion resistance.

Abstract: A process for the production of a face-to-face carpet fabric on a double pile loom having at least two filling insertion planes, uses filling yarns, stuffer warp yarns, and chain warp yarns to form two back cloths. The filling yarns are inserted into each back cloth as back fillings and inner fillings. Groups of chain warp yarns, individual yarns of which between their respective last binding to an inner filling and the succeeding last binding to a back filling form a holding length, are assigned to each back cloth. All patterning pile loops are stretched over back fillings. and the pattern repeat of a group of chain warp yarns is selected to be greater than six. The holding lengths of a chain warp yarn extend over at least three filling insertion cycles.

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.

Abstract: A wetsuit is provided having a torso portion arranged to be secured about a torso of a person. The torso portion includes a neck opening, a pair of upper limb openings and a pair of lower limb openings. A limb extension can be attached to each of the limb openings for covering a respective limb of the person. Each limb extension comprises an elongate tubular member extending longitudinally between an inner end arranged to be secured to the torso portion and an outer free end. The limb extensions can thus be added and removed as desired such that a single wetsuit can be modified for use in varying dive conditions. The use of a single adjustable suit is considerably less costly as compared to purchasing several different types of suits while being convenient enough to adjust to different dive conditions without the need to even remove the torso portion of the suit.

Abstract: The present invention is directed to a process for the production of a single-piece woven garment which can be converted into a full-body garment, similar to an overall or a hospital gown, using a minimum number of seams and a minimum amount of cutting. The garment is made a two-dimensional fabric, with the various parts produced as a single piece. Additionally, the garment can include an integrated infrastructure component for collecting, processing, transmitting and receiving information, giving it intelligence capability.

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.

Abstract: There is provided an apparatus (10) and method for maintaining manuary access to a sufflated body cavity of a patient through a fenestration formed in the patient's body tissue during a minimally invasive surgical procedure.
