  • Patent number: 4695498
    Abstract: The present invention is directed to a low bulk pin-type seam for use with the flat woven fabric. The preferred fabric is woven with continuous or monofilament yarns in the machine direction. The seam is formed by interconnecting loops constructed from the machine direction warp yarns. In constructing the seam loops, a portion of the fabric is made free of cross machine direction yarns and the warp yarns are selected out as either a loop forming yarn or as binder yarns. The fabric is then folded back upon itself in hem like fashion with the selected yarns being retained as loop forming yarns and the binder yarns being drawn back through the hem portion of the fabric to bind the hem and body portion of the fabric. If desired, a stitch pattern may be added to further secure the hem area.
