In this paper, current yarn break sensor systems are investigated and a line laser-based yarn break sensor is proposed. in this proposed sensor system, yarns aligned in the same plane are illuminated with a line light and the light spots on the yarns are detected with a CCD camera, total yarn number is compared with the number of the light spots formed by the line laser on yarns. If the number of the yarns used is greater than the number of the light spots, sensor warns the breaking.
