摘要： A composite yarn comprising a component of staple fibres (Y) and a component formed by a continuous strand (X) 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 (Y Fig. 3) twisted with the continuous strand (X Fig. 3), with some fibres forming an outer sheath (Z Fig. 4) around the core and continuous strand and some fibres (A, B, C Fig. 5) having part of their length in the core and part in the sheath.

摘要： U A method and apparatus for straightening fibres in a sliver (4) comprises subjecting the sliver to sliding frictional contact with a foraminous surface (1) through which an airflow passes, the sliding contact having the effect of both straightening the fibres in the sliver to orientate them, and straightening the hooked ends of any fibres in the sliver, and the influence of the airflow serving to remove dust and/or trash from the sliver.

摘要： A friction spinning apparatus and process use at least one perforated roller (2) enclosing a suction sleeve (4) having the static pressure applied along its suction slot (5, 6, 7) changing between a tip end of the fibre bundle forming the yarn and a downstream location of the fibre bundle whereby the tip end is subjected to a weaker suction effect holding it against the surface (2) than is the stronger downstream part of the fibre bundle.

摘要： The yarn formation area of a friction spinning apparatus, in which the rotating friction rollers (1, 2) and the feed duct (8) 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 (1), which is imperforate, is mounted for pivotal movement away from the area and at a break suction through the other roller (2) is temporarily closed off from one end of the area toward the opposite end to eject the remaining fibres. Return movement of the roller (1) is guided to ensure proper return of the operating position.
