摘要:
An elevator load bearing member (16) includes a plurality of load bearing cords (30) and a woven fabric (22) including a plurality of warp yarns (24) along a length of the load bearing member and a plurality of weft yarns (26) transverse to the length of the load bearing member (16). The woven fabric (32) includes a central portion (32) and lateral edge portions (34) extending along the length of the load bearing member (16). The central portion (32) includes the load bearing cords (30) interlaced with the woven fabric (32). The lateral edge portions (34) each include terminal ends (38) of the weft yarns (26). The central portion (32) has a first plurality of warp yarns (24) situated between laterally outermost ones of the cords (30). The lateral edge portions (34) have a second plurality of warp yarns (24) between the laterally outermost ones of the cords (30) and the terminal ends (38) of the weft yarns (26). At least some of the yarns (24, 26) have a first melting temperature that is higher than a second melting temperature of at least some others of the yarns (24, 26).
