Looms for manufacturing industrial and technical fabrics must be capable of processing a wide variety of fibers and yarns. They must be reinforced, available in various widths, and capable of exact and reproducible settings, resulting in relatively constant fabric characteristics over the length and width. Dornier, Sulzer Textil, and Trustfin exhibited looms for industrial fabric manufacture at ITMA 1999. Sulzer's exhibit included a P 7150 projectile loom weaving a polypropylene warp and weft 56 tex geotextile fabric at a width of 4.18 metes and a weft insertion rate of 1,255 meters per minute. Picanol's Gamma rapier loom wove an acrylic awning fabric using its new Sumo drive concept that drives the main shaft and shedding unit without belts, clutch, or brake. It can accelerate to full speed in less than one machine revolution, which prevents stop marks.
