摘要: The yarn formation area of a friction spinning apparatus, in which the rotating friction rollers and the feed duct lie closely adjacent, is quickly and simply cleaned of remaining fibres at a yarn break and protection is provided against damage caused by excess fibres entering the area. One of the rollers, which is imperforate, is mounted for pivotal movement away from the area and at a break suction through the other roller is temporarily closed off from one end of the area toward the opposite end to eject the remaining fibres. Return movement of the roller is guided to ensure proper return to the operating position.

摘要: A friction spinning apparatus comprises an opening roller system for feeding fibres in a feed duct to the throat formed between the adjacent peripheral surfaces of two parallel drums rotating in the same direction. Yarn formed at the throat, by frictional contact between the fed fibres and the surfaces, is withdrawn along the throat. The fibre feed duct is arranged to feed the fibres in an airstream having a direction inclined to the yarn axis and providing a component of fiber movement opposite to the direction of yarn withdrawal. A suction opening in the duct wall facing away from the drums causes an additional airstream across the duct parallel to the yarn axis to turn the fibres from the direction of inclination to a direction more nearly parallel to the yarn axis as they approach the throat. One of the drums is perforated for suction through its surface, the other is imperforate and formed with a resilient surface of a rubber material.

摘要: A method of open-end spinning a yarn formed of two different types of fibers of staple fiber and a yarn formed thereby in which most of the outer fibers are formed of one type of fiber and most of the inner fibers are formed of the other component. The types of fibers are integrally linked by orienting and distributing the fibers as they approach the open end such that they lie substantially parallel to the open end and overlapping whereby part of some of the fibers of the inner type of fiber wrap around some of the fibers of the outer type of fiber.

摘要: This friction spinner includes an opening roller system for feeding fibers to and through a feed duct to a throat formed between the adjacent peripheral surfaces of two parallel drum rollers rotating in the same direction, one roller perforate so that air may be drawn thereinto through its peripheral surface, and the other imperforate, and rotating such that the imperforate roller rotates out of the throat and the perforate roller rotates into the throat when viewed from above. Yarn formed at the throat, by frictional contact of the fed fibers with the rotating surfaces, is withdrawn along the throat. The fiber feed duct is arranged to feed the fibers in an airstream having a direction inclined to the yarn axis of yarn being formed at the throat and providing a component of fiber movement opposite to the direction of yarn withdrawal, which is to say transverse thereto. An additional airstream is provided across the duct close to its opening within the throat substantially parallel to the direction of the yarn axis as it is formed to turn the fibers from the direction of inclination of the duct to a direction more nearly parallel to the yarn axis as they approach the duct mouth opening.

摘要: Spinning is started on a friction spinning apparatus by drawing the end of yarn back to a position adjacent the surface but in such a condition that it is free from the influence of the suction through the surface. This is done by closing off the suction while the end is in the position so that the yarn is drawn by an additional suction source into an adjacent position. The yarn end is drawn from one end of the surface to lie along the surface by gradually closing off the suction from that end toward the opposite end. Subsequently the suction is reopened to bring the yarn end under its influence to draw the end onto the surface so the fibre feed and take-up can be restarted.

摘要: A composite yarn comprising a component of staple fibres and a component formed by a continuous strand is spun on a friction spinning apparatus. Staple fibres are fed to a twisting zone where the fibres are twisted to form a staple strand with one end open. The continuous strand is joined with the staple strand at a position within a portion of the staple strand which is in the process of being twisted, and such that fibres are joined with the staple strand both upstream and downstream of the joining position and some fibres join with the staple strand on both sides of the joining position. In this way a yarn is formed with some fibres forming an inner core twisted with the continuous strand, with some fibres forming on outer sheath around the core and continuous strand and some fibres having part of their length in the core and part in the sheath.
