Yarn break detector of a spinning machine

摘要

A spinning machine has a ring plate, a ring fixed on the ring plate and a traveler slidably mounted on the ring. The traveler is made of a magnetic material. A yarn break detector of the spinning machine detects the traveler to determine presence or absence of a yarn break. The yarn break detector is characterized in that the yarn break detector includes a magnet and a magnetometer that are located on or above the ring plate. The magnet magnetizes the traveler. The magnetometer uses a magneto-impedance element to detect magnetism of the magnetized traveler.
