Abstract: A false-twist device of the type in which a pair of crossing belts engage and twist the yarn between them utilizes magnetic means to press the belts together and apply a uniform force to the yarn.

Abstract: A rotatable member such as a spindle or rotor of a textile machine having longitudinally spaced anti-friction bearings is supported in a housing by elastic members such as rubber O-rings having a cross-section which provides for progressive dampening. The elastic member supporting the bearing which is subjected to the greatest load has a dampening effect of at least twice that of the other one. The increased dampening of the one elastic member over the other may be obtained by greater mass or softer material.

Abstract: An open end spinning device or a false twisting device having two mutually parallel pairs of rollers for driving a spinning rotor or a twisting tube and a horseshoe-shaped magnet associated therewith for retaining the twisting tube or rotor in a wedge-shaped nip between the pairs of roller, each pole of the magnet acting on a collar on the rotor or twisting tube and being provided with a recess extending parallel to the axis of rotation of the rotor or tube and having a semi-circular cross-section to receive the collar is provided with a magnet having one pole shaped so that upon axially displacement of the rotor or tube away from its normal position by pull of the thread each of the collars still lies opposite the magnet at least at the base thereof.

Abstract: A friction roller for rotating twist tubes in twisting apparatus in which the friction ring is protected from contact with ambient oil by means of a protective coating and a slinger edge disposed on at least one side of the friction ring. The protective layer may be a protective ring which may be integral with the roller or it may be a protective layer of lacquer applied to the friction ring. The layer protects the friction ring from the spinning oil and the slinger edge acts to fling off by centrifugal force that oil which collects around the periphery of the friction roller so that the running surface of the friction ring remains unaffected.In one embodiment the slinger edge projects radially beyond the running surface of the friction ring and there is a peripheral groove on the associated twist tube which cooperates with the slinger edge in the manner of a labyrinth seal, which increases the protection against adverse influences from the spinning oil.
