Disclosed is an apparatus for treating tail yarns in textile spindle assemblies of textile spinning machines, twisters, etc., wherein a stationary upper slit ring and an axially slidable cylindrical member having a lower slit ring at an upper end thereof and a lower portion outwardly expandable by centrifugal force and provided with a spring are mounted on a base portion of a spindle to form a tail yarn gripping means, the pressed state of which is released by sliding the cylindrical member downward by rotational centrifugal force, whereby the yarn underwindings can be automatically removed from the tail yarn gripping means during operation. Further, not only the elasticity of the cylindrical member itself but also the force of the spring is utilized for restoring the lower portion of the cylindrical member from the expanded state to the initial state, and hence the lower portion of the cylindrical member is surely positively restored to the initial state, whereby the tail yarn is surely firmly fixed to the tail yarn gripping means.
