ABSTRACT:
An elbowed yarn exit tube placed at the delivery end of a high-speed hollow rotor contains one or a number of false-twist ribs against which the spun yarn is applied in frictional contact. The ribs form part of a detachable member which is fitted against the periphery of a recess formed in the elbowed portion of the exit tube in the zone nearest the generator-line which has the shortest radius of curvature, the detachable member being locked in position by means of a slidable retaining sleeve.
