Seam construction in papermakers felts or forming fabrics

摘要

A pin seam construction joining together the ends of a multi-layer woven papermakers dryer felt, wet felt, or forming fabric comprises at each end of the felt or fabric (10), a first row of loops (20) formed at the ends of the warp yarns (16) of one layer (12) of the felt or fabric and a second row of loops (26) formed at the ends of the warp yams (22) of a second layer (14) of the felt or fabric. The loops (20) of the first row at one end are interleaved or meshed between the loops (20) of the first row at the other end of the felt or fabric. The loops (26) at one end are similarly interleaved or meshed with the loops (26) at the other end and two pins (30, 28) are threaded through the interleaved rows of loops thus forming a double pin seam construction which is stronger than the usual single pin construction.
