The method is used to operate a ring spinning system (1) which contains a ring spinning machine (2) having a plurality of spinning positions (21) and a winding machine (3) having a plurality of winding positions (31). Yarn (92) is spun at one of the spinning positions (21) and wound up to a cop (91). Values of a spinning parameter are determined at different times during the winding of the cop (91) and stored as spinning data. The cop is transported from the spinning position (21) to one of the winding positions (31). At the winding position (31) the yarn (92) is rewound from the cop (91) onto a yarn bobbin (93). Values of a yarn parameter are determined at at least two different times during the rewinding of the cop (91) and stored as yarn data. The spinning data and the yarn data are automatically assigned to each other in such a way that they relate to the same yarn section. Based on the spinning data and yarn data assigned to each other, an intervention is made on the ring spinning machine (2).

The method is used for the automatic operation of a ring spinning system (1) which contains a ring spinning machine (2) having a plurality of spinning positions (21) and a winding machine (3) having a plurality of winding positions (31). Yarn (92) is spun at one of the spinning positions (21) and wound up to a cop (91). For the spinning position (21), values of a parameter characteristic for the operation of the spinning position (21) are determined during the winding of the cop (91) and stored as spinning data. The spinning data are assigned to the cop (91). The cop (91) is set down from the spinning position (21). The spinning data assigned to the cop (91) is taken into account when deciding whether to feed the cop (91) after it has been set down to one of the winding positions (31). The automatic assignment is based on an identification of a point in time of winding of the cop (91) and an identification of the spinning position (21) at which the cop (91) was wound.

A ring spinning machine includes a reciprocating, displaceably supported spindle rail that is driven by a motor via a shaft that passes through the ring spinning machine. The spindle rail is arranged along opposite sides of the ring spinning machine in a longitudinal orientation of the ring spinning machine and is subdivided into sections along each of the opposite sides. Cross braces extend between the opposite sides of the ring spinning machine and connect opposite sections of the spindle rail. The shaft is supported between the sections of the spindle rail. The spindle rail is suspended from at least one cam disc that is seated on the shaft. A circumferentially biased spring is configured with the shaft or the cam disc to provide torsional compensation on the shaft.

Methods, systems, and apparatus for fabricating nanofiber yarn at rates of at least 30 m/min (1.8 kilometers (km)/hour (hr)) using a false twist nanofiber yarn spinner and a false twist spinning technique are disclosed. In a false twist spinning technique, a twist is introduced to nanofibers in a strand by twisting the nanofibers at points between ends of the strand. This is in contrast to the true twist technique where one end of a strand is fixed and the opposing end of the strand is rotated to introduce the twist to intervening portions of yarn.

A process of yarn spinning and/or twisting, in which a yarn runs between a yarn feeding means (1) towards a yarn picking means is provided. A driving means rotates the yarn picking means at a predetermined speed, in which a stretch of balloon is generated in a point located between the feeding means (1) and the picking means by the presence of twisting means. A helical path with oscillating spiral diameters exists between the yarn feeding means (1) and the yarn picking means, so that the path of the yarn, by the operation of the twisting means, creates a body of revolution from a diameter generating a balloon that has at least a hyperboloid structure (E) forming at least two stretches of balloons (B) consecutive to each other. A machine for performing the process is also provided.

The invention relates to a compacting device, comprising two suction drums (17), wherein a suction drum (17) in each case is associatable with a pair of delivery rollers (7, 8) of drafting unit (2) of a spinning machine, wherein the pair of delivery rollers (7, 8) is made up of a bottom delivery roller (7) and a top delivery roller (8); wherein the suction drums (17) are rotatably supported, via a bearing, on a shaft that is fastened to a carrier element (41); wherein a suction channel (31) extends within the carrier element (41), and wherein the suction drums (17) each have a drive element (40) which in the operating position forms a drive connection with the bottom delivery roller (7). The invention is characterized in that a protective shield (42) for preventing lap formation is situated on the axle (19) of the clamping rollers (18). The invention further relates to a protective shield (42) and a corresponding textile machine.

A method of ring spinning cotton polyester blended yarn. The method is robust and can be used to manufacture the yarn even from polyester fibers that are produced from recycled materials. A new ring spun cotton polyester yarn is also provided. The yarn has few defects and can be effectively dyed when woven into cloth.
