Abstract
A device attached to a spinning or twisting machine, designed to monitor the integrity of two threads merging under tension into a yarn, has a carrier swingable about a horizontal axis and provided with a thread guide, such as a pair of parallel pins, bracketing the yarn downstream of the merger point. A rupture of either thread lets the carrier rotate, e.g. by gravity, from an unstable normal position by half a turn into a stable off-normal position to impede the advance of the remaining intact thread whereby the latter also breaks. Such action, however, is prevented when the yarn is under reduced tension, as during shutdown or startup of the machine, by a locking mechanism arresting the carrier in its normal position. The locking mechanism may include an electromagnet whose winding can form part of a circuit signaling the displacement of the carrier into its off-normal position in response to a thread break.
