ABSTRACT:
Optical scanning and inspection of loomed fabric on one or more looms is carried out using a travelling optical scanner that scans an inspection area of fabric on a loom faster than the fabric traverses the inspection area, such inspection area provided between the weaving portion of the loom and the fabric take-up roll. The scanner generates signals that can routinely be compared with preset reference standards and which can be used to control the stopping of the loom upon the detection of a weaving defect. Fabric moving through multiple looms can be scanned in sequence by a scanner traversing multiple inspection areas of the looms.
