Abstract: A wavy shed forming arrangement for rectilinear weaving looms it consists of a wobbling non-rotating element driven about a driving axis and connected by connections to be reciprocated which are fixed to the lifters on which the warp threads are suspended.

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.
