Textile yarn spinning machine with supply strand interruption

In the combination of

• a textile yarn spinning machine having a plurality of drafting systems arranged in a series, a plurality of supply strand packages each normally delivering a corresponding supply strand to a corresponding drafting system for producing a corresponding attenuated strand and a plurality of trumpet means each mounted adjacent a corresponding drafting system for directing the corresponding supply strand thereinto,
• means movable along the spinning machine and having detector means for monitoring production of attenuated strands and actuator means for responding to breakage of an attenuated strand, and
• means mounted on the spinning machine and selectively remotely actuable by the actuator means for interrupting feeding of the corresponding supply strand at a point in advance of introduction thereof into the corresponding trumpet means,
• an improvement in the interrupting means which assures positive interruption of supply strand feeding, the improvement comprising:
• a plurality of ring means arranged in a series adjacent the series of drafting systems, each said ring means being interposed between a corresponding supply package and the corresponding trumpet means for threadingly receiving the corresponding supply strand, and
• a plurality of plug means for cooperating with said ring means, each said plug means being mounted for movement relative to a corresponding ring means between a strand feeding position withdrawn from said corresponding ring means and a strand interruption position penetrating said corresponding ring means,
• said cooperating plug means and ring means positively entrapping a threadingly received supply strand upon movement of said plug means to the strand interruption position.
