Abstract
Apparatus for twisting a running yarn in a textile machine comprises first and second pulleys mounted for rotation about parallel axes and an endless belt passing around their aligned peripheries so as to provide two runs each of which is twisted through 180.degree. and crosses the other run to form a nip region therewith through which the yarn is guided by yarn guides. One pulley, which may be of larger diameter than the other driven pulley, is mounted on a pivoted arm to tension the belt and/or allow for the use of differing sized belts or differing sized pulleys to alter the crossing angle of the belt and the twist level applied to the yarn.
