Method of Making an Endoluminal Vascular Prosthesis
A flat sheet of woven material includes warp yarns and weft yarns interlaced at substantially right angles to each other. A graft material is cut from the flat sheet of woven material such that the graft material includes a graft material longitudinal axis and the warp yarns are disposed at an angle relative to the graft material longitudinal axis. The warp yarns and weft yarns are not parallel to or perpendicular to the graft material longitudinal axis. The graft material is formed into the shape of an endoluminal prosthesis, such as by rolling opposing edges towards each other and securing the opposing edges to each other. The endoluminal prosthesis thus includes warp yarns disposed at an angle relative to the prosthesis longitudinal axis.

A sewing method to form a trim cover assembly for automotive seat, and an automotive seat using the trim cover assembly. Firstly, a first cover material, a second cover material and a backing tape are used and juxtaposed on one another, with their ends aligned with one another, and then sewn together to create a first seam and a sewn connection portion. Such sewn connection portion is cut off into a shortened sewn connection portion. Thereafter, the first cover material and backing tape are turned over relative to the shortened connection portion and sewn together, thereby forming one portion of the trim cover assembly. Another portion of the trim cover assembly may be formed by avoiding use of the backing tape and simply turning over the first cover material relative to the sewn connection portion, and sewing together the thus-turned portions of the first cover material.

Golf mat
InactiveUS20080125237A1Improve stabilityIncreased durabilityLeather sewingArtificial flowers and garlandsFiberPre stress
A golf mat includes artificial grass fibers attached to and extending upward from a backing material, which may be one or more layers. The artificial grass fibers include groups of at least two different kinds of fiber sewn through a common path in the backing material. One of the kinds of fibers in each group is shaped so as to appear like a blade of grass. The other kind of fiber in each group is pre-stressed / crimped so that the relaxed shape of the fiber is nonlinear, resembling a curlicued or articulated form having lateral excursions. The lateral excursions cause portions of one such pre-stressed fiber to overlap and interfere with another, forming a mesh. The height of the pre-stressed fibers in their relaxed state in the turf is less than the height of the relatively unstressed artificial grass fiber(s). The crimped fibers form a resilient mat with impact characteristics similar to natural turf.
