ABSTRACT:
A ring spinning machine for spinning yarns comprised of finite length fibers has a plurality of spinning locations for combining two untwisted textile strands into a yarn to which a twist is imparted prior to winding up of the yarn. A sensor is associated at each spinning location which reacts to a break of one of the two fiber strands and causes an interruption of the spinning of the yarn. The sensor is designed to sense a characteristic of the yarn which changes in a manner recognizable by the sensor when the yarn is only being spun from one of the two fiber strands and an interrupter is provided which acts in response to the signal from the sensor to interrupt the spinning of the yarn upon the detection of a strand break.
