Abstract: A device is disclosed for detecting yarn breaks in drawing frames and spinning frames comprising a permanent magnet attached to the ring support of the textile machine and an electromagnetic impulse detector also attached to the ring support, close to the path of the traveler which is made at least partially of a ferromagnetic material, said impulse detector being connected, through an amplifier, to a yarn cutting device positioned upstream of the feeding rollers and of the yarn stretching wheel. The electromagnetic impulse detector consists of a coil wound onto a ferromagnetic core.
