    摘要： A flexible longitudinally continuous tape construction is disclosed for use in joining mating edges of juxtaposed members, the tape having an X-like configuration transversely of its length to provide paired legs adapted to receive and be secured along the edges of members to be joined. The tape is capable of serving as a pliable hinge to permit articulation of the joined members about an axis which may or may not be rectilinear; or it may also serve simply as a binding for joining members intended to be fixed relative to each other. The tape construction combines two sets of connector strand means running crosswise of the longitudinal axis of the tape, the strands in one set intersecting and crossing those of the other set to form an axis of intersection along the tape which is flanked by the four legs of the X, while other means are disposed along each leg integrating the connector strands to form with them porous matted portions spaced outwardly of the axis of the X to leave an open center in which the two sets of connector strands are free to shift relative to each other within the limits of the open center defined by the matted portions while retaining a definite single axis of articulation.

    摘要： A warp beam for triaxial weaving consists of a plurality of yarn courses forming a flattened sleeve wrapped spirally upon itself, the yarn courses being disposed in paths generally parallel to one another, and helical with respect to the longitudinal axis of the sleeve. Such a beam is formed by feeding a plurality of warp yarns to a beam take up while feeding the plurality of yarns from a creel with relative rotation of the creel and beam about a yarn path center line between them such that an individual warp yarn from its supply package on the creel rotates about the longitudinal center line of the warp yarn path from the creel to the take up apparatus, and therefore is wrapped helically about a sleeve formed collectively by the warp yarns from the plurality of supply packages on the creel. Triaxial weaving by first forming such a beam and then feeding from such a beam to a triaxial fabric loom whereby the warp yarn courses are made to traverse across the width of the fabric as they are unwound from the beam by virtue of their helical winding within the flattened sleeve of the warp beam is also within the scope of the present invention. Preferably, the helical angle of the individual warp yarns, with respect to the center line of the flattened sleeve along the center of one of the flat sides thereof, is approximately 30*, and preferably the yarn take off from the warp beam is synchronized with the weaving process such that end yarn transfer from above warps to below warps corresponds approximately to yarn take off from the appropriate flattened edge of the sleeve on the beam.
