ABSTRACT:
An apparatus for detecting break or unusual slackening of a yarn in a plurality of yarns, comprising a plurality of a units each having a magazine block formed with an aperture to form part of a continuous bore in the assembly of the magazine blocks, a light-intercepting element having a first angular position uncovering the aperture and a second angular position covering the aperture and a yarn-pass element connected to the light-intercepting element, the yarn-pass element of each of the detecting units being retained by each of the yarns in a raised position holding the associated light-intercepting element in the first angular position thereof; light-emitting means positioned at one end of the bore in the assembly of the detecting units; and light-sensitive signal generating means positioned at the other end of the bore, the beam of light from the light-emitting means being passed throughout the bore and reaching the signal generating means when the light-intercepting elements of all of the detecting units are out of the second angular positions thereof and being intercepted by the light-intercepting element of at least one of the detecting units when the yarn allocated to the particular detecting unit breaks or unusually slackens and allows the light-intercepting element to angularly fall into the second angular position thereof by reason of the weight thereof.
