摘要

Device incorporates a support rail, which carries the slubbing blocker and a thread break stop motion associated with the yarn that is coming out. Rack, which shifts in the support rail, moves the slubbing blocker after a signal delivery by the thread break stop motion and contacts the blocker with the clamping point of the entry roll pair. Thread break stop motion is fastened on the free end of the support rail such that, through the shifting of the rack, a movable monitoring part of the thread break stop motion is moved out of the area surrounding the yarn. After yarn is rejoined, the monitoring part is restored into its operating position. USE/ADVANTAGE - For a drawing system in a spinning machine. Monitoring part does not impediment or disturb during spinning start or maintenance of the drawing system.
