Abstract
A method of detecting a defect of a running yarn comprises steps of producing an electric signal in accordance with a winding speed of a yarn, correcting a reference value corresponding to a length of a defect of a yarn in accordance with the electric signal, and comparing the thus corrected reference value with a detection signal produced from a yarn defect detecting head thereby to detect a defect of the yarn included in the yarn during feeding.
