Ring spinner yarn break detection - has spread magnetic field from sensor in direction of traveller movement

摘要

To establish a yarn break at the spinning points of a ring spinner or twister, where magnetic sensors are located near the ring rail to scan the passage of the traveller on the ring, the magnetic field is spread (6,7) in the direction of travel of each traveller (3). ADVANTAGE - The method gives an improved signal generated by the traveller and registered by the sensor, with a longer signal duration.
