摘要： A machine for unwinding and winding yarn at a speed greater than 1 m/s and without twisting, comprising: a rotary means for the delivery of yarn, comprising a yarn delivery spool and a motor (M1), a rotary means for the collection of yarn, comprising a yarn collection spool, swinging means that define the geometry of the spool, and a motor (M2), where at least the yarn delivery means or the yarn collection means has a torque limiting means with a torque limitation value (Zmax) and always causing a slip velocity (Vdes), understood to be the difference in angular velocity, of the angular velocity of the shaft of the motor associated with the torque limiting means and the angular velocity of the spool associated with the torque limiting means, in such a way that it is possible to establish the tension of the yarn (Twork) measured between the swinging means and the collection spool during the transformation process, and consequently to be able to maintain said yarn tension (Twork) below a maximum tension (tmax) and above a minimum tension (tmin) by modifying the slip velocity (Vdes) alone.

摘要： The invention relates to a method for controlling a compensator of the difference between the drawing-off and winding speeds of yarn (1) when winding yarn on a bobbin (6) at a workstation of a spinning machine, in which the position of a compensating arm (4) of the compensator is controlled at different stages of operation at a workstation, as well as during service operations at the workstation in connection with filling with yarn (1) and emptying an intermediate vacuum storage device (3) of yarn (1) at the workstation. Before the emptying of the intermediate vacuum storage device (3) of yarn (1), the compensating arm (4) of the compensator is deflected across the yarn (1) path and across its working range (α) into its out-of-the-working-range position (B), whereby the yarn (1) is captured by the arm (4) and is also deflected to its out-of-the-working-range position (B), thus forming non-working reserve of yarn, and the arm (4), after being deflected to its out-of-the-working-range position (B), is held in this position by the retaining force (F), whereupon the intermediate vacuum storage device (3) of yarn (1) is emptied, as a result of which the yarn (1) acts by exerting tensile force on the arm (4) of the compensator and overcomes the retaining force (F) holding the arm (4) in the out-of-the-working-range position (B), by which means, as a result of the action of the yarn (1), the arm (4) returns to its operating range (α) and resumes its operation
The invention also relates to a device for the compensation of a yarn (1) loop when winding yarn (1) on a cross-wound bobbin (6) on a spinning machine at a constant speed of the produced yarn (1), which comprises a movable arm (4) of a compensator, the path of the arm (4) intersecting the yarn (1) path between a draw-off mechanism (2) of yarn (1) and a winding device of yarn (1) on a bobbin (6). The compensating arm (4) of the compensator is controllably displaceable between the fully deflected first position (D), a position within its working range (α) and the out-of-the-working-range position (B) behind its working range (α), whereby in this out-of-the-working-range position (B) to the compensating arm (4) is assigned a source of retaining force (F).

摘要： A spinning machine includes a drafting device (7), an air-jet spinning device (9), and a yarn pooling roller (41). The drafting device (7) includes plural draft rollers, including a front roller (20), and drafts a fiber bundle (8). The air-jet spinning device (9) performs spinning to form a yarn (10) by twisting the fiber bundle (8) drafted by the drafting device (7). The yarn pooling roller (41) pools the yarn (10) formed by the air-jet spinning device (9) by winding the yarn (10) around a surface thereof. A peripheral speed of the front roller (20) during yarn discharge spinning and during regular spinning performed after yarn discharge spinning is different. A peripheral speed of the yarn pooling roller (41) during the yarn discharge spinning and during the regular spinning is different.

摘要： A yarn winding device includes a yarn storage roller (51), a tension measuring device, a yarn hooking arm (53), an arm driving section (55), and a control section (60). The yarn storage roller (51) stores a yarn on a surface by being rotatably driven by a roller driving section (52). The tension measuring device measures tension of the yarn pulled out from the yarn storage roller (51). The yarn hooking arm (53) is arranged downstream in a yarn travelling direction of the yarn storage roller (51), and makes contact with the yarn to apply tension to the yarn. The arm driving section (55) rotatably drives the yarn hooking arm (53). The control section (60) feedback controls the arm driving section (55) based on a measurement result of the tension measuring device to adjust an amount of tension applied by the yarn hooking arm (53).
