A weft withdrawing device of an air jet loom includes a blow nozzle blowing a weft that is ejected from a weft insertion main nozzle and determined to be a weft insertion failure to guide the weft to a weft withdrawing passage, a weft introducing duct that is integrally swingable with a sley forward and backward, a weft withdrawing mechanism withdrawing the weft guided to the weft introducing duct, and a weft sensor optically detecting the weft. The weft withdrawing device of the air jet loom includes a weft guide member. The weft guide member includes a cloth fell side top portion and a let-off side top portion. The cloth fell side top portion is located above the weft withdrawing passage.

A textile machine receives a plurality of yarns from respective feeders, each provided with a control unit that calculates, for each garment produced, the amount of yarn consumed (YCmeas) and compares it with a reference consumption value (YCref). If the difference exceeds a preset limit value (% max) that indicates an anomaly, then an alarm is generated. Periodically, the control unit calculates an average consumption value (YCmed) on the basis of a preset number (Nmed) of already-finished garments, and compares it with the reference consumption value (YCref). If the difference exceeds a preset threshold value (% maxmed), then the reference consumption value (Yref) is set to the average consumption value (Ymed).

Weaving equipment may include warp strand positioning equipment that positions warp strands and weft strand positioning equipment that inserts weft strands among the warp strands to form fabric. The fabric may include insulating strands and conductive strands. The conductive strands may be coupled to electrical devices using solder joints or other conductive connections. During weaving, an electrically controlled shuttle may dispense weft strands between warp strands. The electrically controlled shuttle may include control circuitry and communications circuitry. The communications circuitry may be used to support communications between the control circuitry and equipment external to the shuttle. Movable arms, cutters, heaters, soldering devices, strand dispensers, intertwining devices, and other electrically controlled devices may be incorporated into the shuttle and controlled by control signals from the control circuitry.
