The invention relates to a yarn package provided on a yarn package holder, such as a tube, wherein the yarn is at least partly unstable, such that a variation in the yarn tension results in a rotational movement thereof, characterized in that, the position of the yarn in the yarn package is controlled by the direction of the rotation of the yarn. The invention further relates to a method for winding a yarn on the yarn package holder, such as a tube, forming a yarn package, wherein the position of the nodes is being determined and to an apparatus for the production of alternate twist plied yarn and for the formation of a yarn package by winding said alternate twist plied yarn on a yarn package holder, such as a tube, having a means for producing alternate twist plied yarn, a means for guiding the alternate twist plied yarn along the longitudinal axis of the package being formed whereby the means for producing the alternate twist plied yarn is synchronized with the means for guiding the alternate twist plied yarn along the longitudinal axis of the package.

A yarn texturing machine for texturing a plurality of thermoplastic yarns, each in a processing station. The yarns are guided and advanced in each processing station by a plurality of feed systems. One of the feed systems comprises a driven feed roll which is partially looped by the advancing yarn, and a guide member mounted for movement relative to the feed roll for movement between a threading position wherein the yarn is separated from the feed roll and an operating position wherein the yarn engages the feed roll.

A transportation and storage system for spinning machines with transfer storage places associated with each spinning machine. With an automatic supply of the spinning machine via transporters as the connecting means between the transfer storage place and the spinning machine, the goal is to manage exclusively with straight guides. The spinning cans are supplied to the transfer storage place with the same spatial orientation with which they are emptied in the spinning machine.

In what is referred to as an air vortex spinning method, fibres are dispersed by a dispersion roller (5) into individual fibres, and conveyed by means of a suction roller (9) against a fibre conveying channel (15), from which the fibres are conducted against the mouth of a yarn channel of a hollow spindle (13). In this situation, the front ends of the fibres are taken up in the yarn channel (14), while the rear ends are acquired by a rotating air flow R and rotated around the mouth area of the spindle or yarn channel, so that a yarn is formed which exhibits at least a surface which displays a character similar to a ring-spun yarn. Th principle according to the invention is that, on the one hand, the fibres are separated at the transfer from the dispersion roller (5) to the suction roller by an abrupt change of direction at the baffles or deflector plates 8 and 17 from the trash particles, these particles being unable to follow the abrupt change of direction because of inertia, in such a way that these trash particles, which cause spinning interruptions in the area between the outlet of the fibre conveying channel (15) and the intake of the yarn channel (14), are separated out in good time before the inlet into the fibre conveying channel.

A yarn false twist texturing machine for texturing multifilament synthetic yarns (4), wherein a heating device and a false twist unit are arranged within a false twist zone. An aftertreatment zone accommodates a second heating device and a countertwist device. The countertwist device is used to remove any residual twist that is left in the yarn by the false twist unit. To be able to perform a selective treatment by the countertwist device, a first embodiment provides for a twist imparting member yarn guide means for guiding the yarn (4) and being adapted for reciprocal movement between an idle position for not treating the yarn (4) or for threading it and an operating position for treating the yarn (4). In a second embodiment, the countertwist device comprises a movable twist imparting member (28, 29), which is adapted for reciprocal movement between an idle position for not treating or for threading the yarn (4) and an operating position for treating the yarn (4) by twisting it.
