Methods and systems for triggered on-loom fabric inspection
On-loom fabric inspection system (500) including an imaging device (522) configured to collect images of a weaving area (518) of a loom (502). An image-capture trigger-mechanism (529) triggers the imaging device (522) to capture images at required instants during the weaving cycle. An image processor (524) receives data from the imaging device (522) and further detects irregularities in the data.

Base fabric, jet loom, and method of manufacturing base fabric
A base fabric, having a coefficient of variation CV1 (100×standard deviation/average value) of 3.0% or less in a length direction of a weft-direction disintegrated yarn strength and a coefficient of variation CV2 (100×standard deviation/average value) of 4.0 or less in a length direction of a weft-direction disintegrated yarn elongation.

Method for controlling the consumption of yarn in a weaving process
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).
