[0020] The present invention will be further described below in conjunction with the drawings and embodiments, but it is not a basis for limiting the present invention.
[0021] Examples. An alarm method for broken ends of a two-for-one twister, which is characterized in that: the yarn is supported by a rotatable guide wheel on the main shaft and rotates under the action of the yarn's own weight, tension and friction; the main shaft and the light hole on the guide wheel When the guide wheel rotates once per revolution, the light is passed through the main shaft once; when the yarn breaks, the guide wheel stops rotating, and the "light-shading" cycle process in the main shaft stops; by detecting the "light-shielding" in the spindle -Whether the "shading" cycle process is stopped to determine whether the yarn is broken, and the sound and light alarm is activated when the broken ends are confirmed.
