Yarn stop-motion device

A yarn stop-motion device operatively associated with a yarn-processing apparatus, said device comprising a supporting frame, stationary guide means secured to said frame, a single yarn break-detector means pivotally mounted on said frame and means for severing a yarn guided by said guide means positioned near to said yarn break-detector means, said yarn break-detector means detecting yarn breaks occurring along the entire yarn path of a yarn passing through said yarn-processing apparatus and being positioned to contact the yarn in the yarn path downstream of the yarn-processing apparatus.

A yarn stop-motion device comprising a supporting frame, stationary guide means secured to said frame, yarn break-detector means pivotally mounted on said frame and means for severing a yarn guided by said guide means positioned near to said yarn break-detector means, said means for severing the yarn comprising a stop-member secured to the supporting frame and at least one clamp bar on a pivotal support member, and said yarn break-detector means including a yarn guide element mounted on said pivotal support member.

A yarn stop-motion device comprising a supporting frame, stationary guide means secured to said frame, yarn break-detector means pivotally mounted on said frame, means for severing a yarn guided by said guide means positioned near to said yarn break-detector means, and a triggering means for retaining the yarn-severing means and the yarn break-detector means in an inoperative state during thread-up of the device, said triggering means comprising a two-arm lever pivotally mounted on said supporting frame and a projection extending from the one arm of said pivotal support member, said two-arm lever contacting said projection when the yarn-severing means and the yarn break-detector means are in an inoperative state.
