Abstract
The disclosure is of a seam construction for joining the ends of woven papermakers felt or dryer felts, wet felts forming fabrics characterized in part by a first system of lengthwise yarns in one layer and a second system of lengthwise yarns positioned above the first system. The seam comprises looped ends of the lengthwise yarns projecting from the respective ends of the fabric, and positioned to interleaf with the opposite end loops. Pins are placed through the interleafed loops so as to provide joinder in the two systems, respectively, of the felt or fabric.
Claims10
A pin seam construction joining together the two ends of a multi-layered, woven papermakers felt or forming fabric characterized in part by a first system of lengthwise yarns in one layer and a second system of lengthwise yarns positioned above the first system, which comprises;
- a plurality of first loops protruding from the two ends of the fabric on a plane co-extensive with the plane of the lengthwise yarns in the first system of lengthwise yarns;
- a plurality of second loops, protruding from the two ends of the fabric on a plane co-extensive with the plane of the lengthwise yarns in the second system of lengthwise yarns;
- said loops being anchored in the body of the felt or fabric;
- said loops in one end being alternately displaced in respect to the loops of the other end so that the loops of the one end will interleaf with the loops of the other end when the ends are brought together to form a seam at the interleafed loops;
- a first pintle through the plurality of interleafed first loops;
- and
- a second pintle through the plurality of interleafed second loops;
- said pintles joining the interleafed loops in a seam construction.
