Textile yarn spinning machine with improved supply strand interruption means

摘要

Apparatus for use in combination with a traveling unit including sensor and remote actuator means to interrupt supply strand feeding to drafting systems of a textile spinning machine. A collar means is rotatably mounted on an elongate strand guide and one side thereof serves as a strand engaging surface. An abutment member mounted on the strand guide serves as the other of the strand engaging surfaces. Means are provided for moving the strand engaging surfaces longitudinally along the elongate strand guide and into a proximate relation with one another upon the sensing of a broken yarn so as to pinch the supply strand and thereby interrupt feed of the supply strand to the drafting system.
