Abstract: A winding station for winding textile yarn onto empty tubes is disclosed. The winding station includes a winding mechanism (1) with two flanges (2) for gripping the ends of the tube (8). Each flange is mounted on a pivoted winding arm (6). These arms position the empty tube (8) in contact with a driving roller (14) so that the longitudinal axis of the empty tube (8) is above the longitudinal axis of the driving roller (14). A stationary, linear magazine (4) with a filling end (5) and a feeding end (7) is included. The filling end (5) and the feeding end (7) of the magazine (4) are inclined at angle, alpha, of less than or equal to 45°, to the driving roller (14). A lifting mechanism (11) includes a pivoted arm (9) terminating in a tube carrier (10). The tube carrier (10) is configured to bring an empty tube from the feeding end (7) of the magazine (4) to a space between the flanges (2) by an arc movement of the arm (9). A winding assembly and method are also disclosed.

Abstract: 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. The position of the yarn in the yarn package is controlled by the direction of the rotation of the yarn. Also a method for forming a yarn package, wherein the position of the nodes is determined. An apparatus for the production of alternative twist plied yarn and for the formation of a yarn package by winding the alternate twist plied yarn on a yarn package holder, such as a tube, producing alternate twist plied yarn, guiding the alternate twist plied yarn along the longitudinal axis of the package being formed whereby the producing the alternate twist plied yarn is synchronized with the guiding the alternate twist plied yarn along the longitudinal axis of the package.

Abstract: A yarn monitor for an automatic cross winding and yarn assembly machine in which at least two yarns are wound in parallel from two run-off bobbins onto a cross bobbin. The monitor includes a drive roller for driving round the cross bobbin, a driver for rotating the drive roller in two opposite directions and a wind-off eye for leading the two yarns to the cross bobbin. A yarn guide is provided for axially guiding the yarns on the cross bobbin, the yarn guide being installed between the cross bobbin and the wind-off eye for controlling and correcting the position of the two yarns with respect to one another. The yarn guide comprises a cutting apparatus for cutting at least one of the yarns and a driver for the cutting apparatus. A yarn guide is provided for guiding the yarns co-operating with the cutting apparatus. Sensors are provided for detecting the yarns in the yarn guide and for controlling the cutting apparatus.

Abstract: The machine comprises a yarn guide for axially guiding the yarn on the receiving cross bobbin, for each wound off yarn at least one yarn watcher, a cutting device for cutting through the yarn, a yarn tensioner and a joining device for joining yarn ends, where a yarn monitor with a method of controlling is provided for controlling and correcting the assembled yarn bundle and rewinding the cross bobbin, a gripper device for gripping the yarn ends on the cross bobbin, a gripper device for inserting each yarn into the joining device, a gripper device for receiving and holding the yarn ends, a wind-off eye for the shared winding-off of the assembled yarns installed above the yarn joining devices, and a method of control for these devices, where the method of control are separately controlled.

Abstract: A yarn guide device for the formation of cross-wound bobbins in textile machines, comprising a driven cylinder having over the entire length of its outer surface an uninterrupted helical groove for guiding the yarn in one direction of the transverse movement with respect to the direction of the run movement of the yarn and a helical groove running in the opposite direction and interrupted by the first groove for guiding the yarn in the other direction of the transverse movement of the yarn; a rotating driven rotor installed before and under said driven grooved cylinder; said rotor including at least one carrier for pre-aligning the yarn during its transverse motion imposed by the uninterrupted groove of said grooved cylinder; and means for driving the rotor with a speed having an unchanging relationship to the speed of rotation of the grooved cylinder.

Abstract: The invention pertains to a device for forming and depositing loops of yarn in such a manner on an endless belt conveyor which passes through a yarn processing chamber, that the loops partially overlap and lie sufficiently free to be able to undergo any sort of processing. This known processing of the yarn may, for instance, consist of a heat processing, for instance by means of steam under pressure.
