Developments in weaving technology shown at ITMA 1999 included increased use of electronic controls for weaving and ancillary operations and advances in selvage motions and leno devices. Schleicher's P2 jacquard mechanism uses a piezoelectric selection device that consumes very little power and generates very little heat. Grosse's prototype Unished jacquard mechanism mounts directly on top of the loom and does not use any pulleys, harnesses, or spring return motions. Staubli's prototype Unival 100 jacquard mechanism weaves at 950 picks per minute with 7,124 individually controlled ends. Tsudakoma and Toyoda showed water jet looms weaving at 1,500 and 1,600 picks per minute. One Toyoda loom featured four color weft patterning. Tsudakoma showed an air jet loom weaving at speeds of up to 1,800 picks per minute. Somet, Picanol, and Dornier showed air jet looms featuring double pick insertion. The Cortex Loomprinter prints patterns directly onto filament and silk warps during the weaving process.
