Abstract
A weft sensing system for a weaving machine such as an air jet loom or a water jet loom includes an image sensor camera for scanning at least a line passing through a weft insertion path to detect an abnormal weft insertion. The image sensor camera is set to perform one or more scans in each pick, and connected with an image processor which monitors the size or position of an image of a weft yarn. Preferably, the image sensor camera is positioned on the front side of the reed.
