Electronic Monitoring and Fault Detection on Rapier Looms
topic
Rapier loom monitoring systems use weft break sensors, warp break drop wires, rapier position encoders, and fabric inspection cameras to detect weft missing, warp breaks, rapier timing deviations, and fabric appearance defects in real time, triggering automatic loom stop and positioning the fell at the fault location for operator repair while logging fault type, frequency, and location data for quality management reporting.
Role
Minimises the length of fabric produced with undetected weaving defects by stopping the loom immediately when a fault is detected, with monitoring system sensitivity and response time determining the number of picks of defective fabric produced before detection and stop, with rapid detection reducing fabric defect length and the repair or cut-out waste associated with each fault occurrence.
