  • Shaped monofilament coil seam and fabrics
    Patent number: 4862926
    Abstract: A spiral seam construction for lower caliper, multi-layer papermaking fabrics. The spiral seam members have a plurality of headcurves which are interconnected by a plurality of winding legs. Each of the winding legs has a cross-section in which the vertical dimension is less than the horizontal dimension, whereby it is possible to use a larger seaming pintle without an associated increase in seam caliper. The winding legs determine the maximum caliper of the seam, and the seam does not exceed the final fabric caliper.
