<p>A shed formation device (1) with a frame assembly (60) having at least two harnesses (23, 24) mounted for movement in the frame. Each harness includes a plurality of heddles (25) through which CMD yarns (15, 20) are passed. The existing CMD yarns (15) of the fabric (10) pass over an out-feed bar (95) mounted to the frame assembly (60) as they exit the heddles (25). A replacement CMD yarn (20) supply provides replacement CMD yarns to the heddles (25) for reweaving with the MD yarns (12, 13) to form seam loops (38) and finished fabric ends (39). The replacement CMD yarns (20) pass over an in-feed bar (94), mounted to the frame assembly (60), prior to passing through the heddles (25). A weave repeat pattern means forms an unweaving shed (28) in the existing CMD yarns (15) and reweaving shed (29) in the replacement CMD yarns (20). Retractable spreader means (40, 50) facilitate the unweaving and reweaving of the MD yarns (12, 13). A leasing device (105) captures MD yarns (12, 13) from the unweaving shed (28) and releases them into the reweaving shed (29) to form seam loops (38) and finished ends (39).</p> |
