Claims

[Claims for Utility Model Registration] ■ An open-end spinning machine in which the yarn spun by a spinning unit is drawn upward by a presser roller and a draw-off roller, and wound by a winding drum located above the draw-off roller. A yarn breakage detection device is provided between the draw-off roller and the winding drum,
The similar breakage detection device includes a detection lever that is rotatably pivoted so as to include a horizontal movement component and can be held against the thread, and an urging force that urges the detection lever in the direction of engagement with the thread. and thread breakage detection means for detecting rotational movement of the detection lever and outputting a thread breakage detection signal when engagement with the thread is released and the detection lever is rotated at the time of thread breakage, A yarn breakage detection device for an open-end spinning machine, characterized in that a guide portion is bent at the tip of the lever so that spliced yarn can be re-engaged after yarn breakage. 2. The yarn breakage detection device for an open-end spinning machine according to claim 1, wherein the yarn breakage detection means is a reed switch that is operated by a magnet when a magnet provided on the detection lever rotates. 3. The detecting lever has its rotation axis inclined so that the end portion capable of engaging with the thread is biased in the engaging direction by its own weight. Yarn breakage detection device for open-end spinning machines.
