  • Patent number: 4315049
    Abstract: A novel low bulk seam is disclosed for use in paper making machine fabrics, such as dryer felts. The seam is particularly adapted for use with multi-filament yarns which comprise multi-ply fabrics. A novel method for producing this seam is disclosed which comprises the insertion and adhesion of a seaming coil, the removal of picks in adjacent fabric areas, the folding and overlapping of such areas, the creation of a warp fringe, and the pulling of portions of that fringe into and through portions of the fabric body fasteners to create a stitchless seam providing substantially uniform thickness and air permeability across the full fabric width. A durable, reliable, non-marking seam is accordingly provided for use with spun, mono-filament and/or multi-filament fabrics.
