Yarn break detector in ring frames

摘要

Apparatus is disclosed herein which detects breaks in spinning yarns in ring spinning frames or the like and in particular senses vibrations inherent to a yarn guide disposed on a bobbin when the yarn guide comes into contact with the spinning yarns. The apparatus achieves quick inspection of whether breaks occur with the spinning yarns by the presence and absence of the vibrations, thereby monitoring joints in the spinning yarns and the operating state of the spinning machine.
