Yarn defect classifying device and yarn winding machine

摘要

A yarn defect classifying device for a yarn winding machine includes a yarn defect detecting device (5) adapted to detect a yarn defect , a removal determination section (53N, 53S, 53L) adapted to calculate a removal determination value for a set length of the yarn ( Y ) inaccordancewithadetectedthickness of the yarndefect detected 10 by the yarn defect detecting device ( 5 ) , and to determine removal of the yarn defect when the removal determination value exceeds a prescribed value, and a calculating section (54N, 54S, 54L) adapted to calculate a display thickness and a display length of the yarn defect inaccordance with the detectedthickness and a detectedlength of the yarn defect.
