摘要： A spinning station (30) of a rotor spinning machine comprising:
- a sliver feeding mechanism (21), an opening mechanism (22), a spinning rotor (19) producing a yarn from said sliver,
- a yarn take-up device (6) comprising a take-up roller (11) and a pressing roller (12) cooperating each other with the yarn coming from said spinning rotor (19),
- a winding mechanism (14) comprising a winding roller (13) and a package (15) so as to wind said yarn on said package (15),
- said yarn take-up device (6) intercepting the yarn (5) and comprising a tube (4) able to house and accumulate at least partially said yarn (5),
- a control unit (25) operatively connected with said yarn take-up mechanism (6), with said sliver feeding mechanism (21) and with said winding mechanism (14), the control unit (25) being programmed so that
- during spinning, the yarn take-up device (6) sucks at least partially a portion of the yarn (5) within said tube (4), in order to control the loosening of the yarn (5) during spinning and then gradually releases it back for winding, wherein the yarn take-up device (6) contains an air injector (1) to create a negative pressure (9) within said tube by means of compressed air (8), so as to suck said yarn (5).

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： Accumulation-type thread feeder including: a body, which bears a rotary drum on which turns of thread from a spool are wound; a tension sensor for detecting value of tension of exiting thread and a detector for detecting thread quantity accumulated on the drum; a light-reflecting element on the drum or functionally associated therewith, such light generated by light a generator borne by a support arranged alongside the drum, the support associated with a detector to detect light reflected by the reflecting element, the reflected light varying as a function of the quantity of thread wound on the rotary drum, the detection allowing detection of such thread quantity. The detector is a light-sensitive member directly receiving the light reflected by the reflecting element along the entire surface of the drum, the member allowing determination of thread density on the drum.

摘要： The invention prevents a slack of a wire rod in a spool by preventing the wire rod fed by rotation of the spool from returning to the spool.
A wire rod slack preventing device (20) is installed parallel to a wire rod feeding machine (10) feeding a wire rod (11) by rotating a spool (12), around which the wire rod (11) is wound, and has a reverse rotation roller (26) having a rotating axis which is parallel to a rotating axis of the spool and rotating in a reverse direction to a rotating direction of the spool while being in contact with the spool, a forward rotation roller (27) having a rotating axis which is parallel to the rotating axis of the reverse rotation roller (26) and rotating in the same direction as the spool while being in contact with the reverse rotation roller (26), and a pinching roller (28) having a rotating axis which is parallel to the rotating axis of the forward rotation roller (27) and pinching the wire rod, which is fed out of the spool, together with the forward rotation roller (27). Further, a wire rod slack preventing method draws the wire rod which is fed out due to the rotation of the spool, while pinching the wire rod by the forward rotation roller (27), which rotates with the rotation of the spool, together with the pinching roller (28).

摘要： In der Spulstation einer Spulmaschine wird Garn (2) mit einem Garnreiniger (9) auf Fehlstellen geprüft. Bei Detektion einer Fehlstelle wird das Garn (2) zunächst durch den Garnreiniger (9) zurückgezogen, wobei das Garn nochmals genauer geprüft wird. Sodann wird die Fehlstelle am zurückgezogenen Garn herausgeschnitten, worauf das Garn (2) wieder verspleisst wird.

摘要： Die Erfindung betrifft ein Verfahren, das Schwankungen der Drehzahl bei Kreuzspulen (8), insbesondere zu Beginn der Spulenreise reduziert, sowie eine Kreuzspulen herstellende Textilmaschine zur Durchführung des Verfahrens. In den Arbeitsstellen (2) einer Spinnmaschine (1) werden im so genannten Spulapparat (4) neben zylindrischen auch konische Kreuzspulen (8) hergestellt, für deren gleichmäßigen Spulenaufbau die Zuführung des Fadens (7) mit einer konstanten Wickelspannung außerordentlich entscheidend ist. Schwankungen in der Wickelspannung können neben lockeren Fadenlagen auch zu Fadenbrüchen führen, die den kontinuierlichen Spinn- und Wickelprozess beeinträchtigen. Zur Vermeidung dieser Effekte ist erfindungsgemäß vorgesehen, dass bereits vor einem Anlege- oder Anspinnvorgang die Drehimpulse der Kreuzspule (8) sensorisch erfasst werden, sowie aus der zeitlichen Abfolge der jeweilige Antriebsdurchmesser berechnet wird, um darauf basierend insbesondere bereits zu Beginn der Spulenreise die Drehzahl der Spulenantriebswalze (10) zu wählen.
