Abstract
A yarn breakage detecting system includes yarn detectors for detecting warp yarns forming a warp and for providing yarn detection signals, and a signal processing unit for counting peaks in the yarn detection signals, representing the warp yarns and for providing a yarn breakage detection signal when the number of peaks is smaller than a predetermined number. The warp yarns are divided into a plurality of groups and the adjacent groups are spaced apart by a predetermined distance greater than the pitches of the warp yarns in the groups by spacers or demarcated by identifiers, and the yarn detectors are respectively assigned to the groups of warp yarns. Since the monitoring range of each yarn detector is relatively narrow, the yarn detector can accurately detect the warp yarns at a high resolution in a relatively short time.
