Abstract: A stop spindle for textile machines, particularly spinning and twisting machines. A ferromagnetic clutch element, formed e.g. by a circular disc, is mounted axially displaceably between the whirl of the stop spindle and a brake lining behind which there is mounted an electromagnet. The brake lining is made of non-magnetic material and is mounted between the pole shoes of a permanent magnet. The electromagnet is energized by an electric pulse so as to create a magnetic field which is additive with respect to the magnetic field of the permanent magnet, whereby to start the driving of the spindle; the electromagnet is energized by an electric pulse so as to create a magnetic field which is substractive with respect to the magnetic field of the permanent magnet whereby to stop the driving of the spindle and to brake it.

Abstract: Method of spinning staple fibers by imparting false twist to a continuous fiber bundle. The continuous fiber bundle is formed by a successive doubling of separated fibers, and is thereupon twisted by means of a false twisting element, the separated fibers being distributed along the twisted length of the fiber bundle, as well as along the untwisted section of the continuous fiber bundle.

Abstract: Apparatus for cleaning the rotor of the spinning unit for the open-end spinning of yarn. The apparatus has a cleaning head with cleaning elements arranged in the form of a rotary brush mounted upon a rotatably driven shaft. In the cleaning head, at the rear side of the brush, there is provided at least one projection which deflects or bends the bristle of the brush axially outwardly at intermediate portions thereof so as to reduce their effective diameter so as to enable them to penetrate into the inlet opening of the spinning rotor.

Abstract: Method of and apparatus for splicing fibrous formations, particularly yarns. Mutually closely arranged parallel and overlapping ends of the fibrous formations to be spliced are disposed inside the pressure channel of a splicing chamber. The thus disposed fibrous formations are subjected to the whirling action of pressure air and at least at one of the mouth of said pressure channel they are subjected to the action of an air flow from the pressure channel, such air flow vibrating at a high frequency. Such vibration of the air flow is achieved by directing the air flow column from the pressure channel toward an obstacle confronting and near the mouth of the pressure channel. Such obstacle may be made adjustable, whereby to adjust the frequency of vibration of the air flow column.

Abstract: Method of and apparatus for preparing and splicing the ends of fibrous formations, particularly in the pressure channel of a pneumatic splicing chamber provided with a displaceable lid. Excess lengths of ends of fibrous formations to be spliced are placed within the pressure channel in overlapping substantially parallel relationship and are then cut to a desired length by cutting means such as scissors. Following such cutting operation, the fibrous formations within the pressure channel are bent without gripping over the edges of the mouth of the pressure channel, whereby to hold the sections of the fibrous formations within the channel in generally parallel relationship.
