Description

Die Erfindung betrifft eine Vorrichtung zum Veredeln einer Fadenschar und / oder Verarbeiten einer Fadenschar zu einem Flächengebilde mit einem Prozessabschnitt und einer dem Prozessabschnitt vorgeschalteten Abwickelstation, die eine Aufnahme für einen Materialträger aufweist, von der die Fadenschar in eine Prozessrichtung abziehbar ist.The invention relates to a device for refining a yarn sheet and / or processing a yarn sheet to a sheet with a process section and an unwinding station upstream of the process section, which has a receptacle for a material carrier, from which the yarn sheet is peelable in a process direction.

Ferner betrifft die Erfindung ein Verfahren zum Veredeln einer Fadenschar und / oder Verarbeiten einer Fadenschar zu einem Flächengebilde, bei dem man die Fadenschar von einem Materialträger in eine Prozessrichtung abzieht und durch einen Prozessabschnitt führt.Furthermore, the invention relates to a method for finishing a yarn sheet and / or processing a group of threads to a sheet, in which one draws the yarn sheet from a material carrier in a process direction and leads through a process section.

Zum Herstellen eines textilen Flächengebildes, beispielsweise einem Gewebe, wird eine Fadenschar auf einem Materialträger bereitgehalten. Die Fadenschar wird dann von dem Materialträger abgezogen und durch den Prozessabschnitt geführt. Bei einem Webvorgang bilden die Fäden der Fadenschar dann die sogenannten Kettfäden, die mit Hilfe von Schussfäden zu einem Gewebe verarbeitet werden.For producing a textile fabric, for example a fabric, a group of threads is kept ready on a material carrier. The yarn sheet is then removed from the material carrier and passed through the process section. In a weaving process, the threads of the group of threads then form the so-called warp threads, which are processed by means of weft threads into a fabric.

In vielen Fällen muss die Fadenschar vor dem Verarbeiten zu einem Flächengebilde noch veredelt werden. Ein Beispiel für eine derartige Veredelung ist das Auftragen einer Schlichte. Die Veredelung und die Verarbeitung der Fadenschar zu einem Flächengebilde können unmittelbar hintereinander erfolgen (siehe z.B. EP0125697 )In many cases, the yarn sheet must be refined before processing into a sheet. An example of such refinement is the application of a size. The finishing and the processing of the yarn sheet to a sheet can be done directly behind each other (see, eg EP0125697 )

Es ist aber auch möglich, diese beiden Arbeitsschritte voneinander zu trennen.But it is also possible to separate these two steps from each other.

Der Materialträger ist in vielen Fällen ein sogenannter Kettbaum. Der Kettbaum weist an seinen beiden axialen Enden üblicherweise senkrecht zur Rotationsachse des Kettbaums gerichtete Kettbaumscheiben auf, mit denen verhindert wird, dass die Fäden an den axialen Enden von dem auf den Kettbaumkern aufgewickelten Wickel herunterfallen. Die Herstellung eines derartigen Kettbaumes ist relativ aufwendig, weil die Fäden mit einer hohen Genauigkeit auf dem Kettbaum angeordnet müssen. Fehler der Positionierung der Fäden der Fadenschar auf den Kettbaum ergeben später beispielsweise Fehler in dem Flächengebilde, das mit Hilfe der Fadenschar erzeugt werden kann.The material carrier is in many cases a so-called warp beam. The warp beam has at its two axial ends usually perpendicular to the axis of rotation of the warp beam directed Kettbaumscheiben on, which prevents the threads fall off at the axial ends of the wound on the warp beam core winding. The production of such a warp beam is relatively expensive because the threads must be arranged with high accuracy on the warp beam. Errors of the positioning of the threads of the group of threads on the warp later result, for example, errors in the fabric, which can be generated with the help of the yarn sheet.

Der Erfindung liegt die Aufgabe zugrunde, das Veredeln einer Fadenschar und / oder das Verarbeiten einer Fadenschar zu einem Flächengebilde kostengünstig zu gestalten.The invention has for its object to make the refining a yarn sheet and / or the processing of a group of threads to a fabric inexpensively.

Diese Aufgabe wird bei einer Vorrichtung der eingangsgenannten Art dadurch gelöst, dass die Aufnahme quer zur Prozessrichtung verlagerbar ist und einen Verlagerungsanrieb aufweist, der durch eine Steuereinrichtung gesteuert ist.This object is achieved in a device of the type mentioned above in that the recording is transversely displaceable to the process direction and a displacement drive controlled by a controller.

Bei einer derartigen Vorrichtung werden an die Qualität des Materialträgers geringere Anforderungen gestellt. Man kann durchaus zulassen, dass die Fäden der Fadenschar in einzelnen Windungen des auf den Materialträgers aufgewickelten Fadenwickels parallel zur Achse des Materialträgers seitlich zueinander versetzt sind. Diesen Versatz der Fäden der Fadenschar kann man dadurch ausgleichen, dass man den Materialträger beim Abwickeln der Fadenschar quer zur Prozessrichtung versetzt. Damit können Positionierungsfehler ausgeglichen werden oder man kann sogar einen Materialträger verwenden, bei dem die Fäden nicht mehr alle senkrecht übereinander aufgewickelt worden sind. Dementsprechend lässt sich die Herstellung des Materialträgers kostengünstig gestalten, was das Veredeln der Fadenschar bzw. das Verarbeiten der Fadenschar zu einem Flächengebilde kostengünstig macht.With such a device, lower requirements are placed on the quality of the material carrier. It is quite possible that the threads of the group of threads in individual turns of the wound on the material carrier thread winding parallel to the axis of the material carrier are laterally offset from each other. This offset of the threads of the group of threads can be compensated for by displacing the material carrier transversely to the process direction during unwinding of the group of threads. This can be compensated for positioning errors or you can even use a material carrier in which the threads are not all wound vertically one above the other. Accordingly, the production of the material carrier can be made cost-effective, which makes the refining of the yarn sheet or the processing of the yarn sheet to a fabric cost.

Vorzugsweise weist die Aufnahme einen Umdrehungszähler für den Materialträger auf. Wenn die Fadenschar nach einer gewissen Gesetzmäßigkeit auf den Materialträger aufgewickelt worden ist, bei der sich beispielsweise bei jeder Umdrehung ein gewisser kontinuierlicher Versatz der Fadenschar parallel zur Rotationsachse des Materialträgers ergibt, dann kann man anhand der ermittelten Umdrehungszahl des Materialträgers diese Funktion sozusagen wieder rückwärts abfahren und die Bewegung des Materialträgers quer zur Prozessrichtung, also parallel zu seiner Rotationsachse, entsprechend steuern. Damit wird dafür gesorgt, dass die Ränder oder Kanten der Fadenschar immer an der gleichen Position verbleiben.Preferably, the receptacle has a revolution counter for the material carrier. If the group of threads has been wound on the material carrier after a certain law, in which, for example, with each revolution, a certain continuous offset of the yarn sheet parallel to the axis of rotation of the material carrier, then you can descend on the basis of the determined number of revolutions of the material carrier, this function, so to speak, backwards and the movement of the material carrier transverse to the process direction, ie parallel to its axis of rotation, control accordingly. This ensures that the edges or edges of the yarn sheet always remain in the same position.

Zusätzlich oder alternativ dazu kann vorgesehen sein, dass die Steuereinrichtung einen Signaleingang aufweist, in den Aufwickelinformationen des Materialträgers eingebbar sind. In manchen Fällen ist es möglich, beim Aufwickeln der Fadenschar auf den Materialträger eine Information darüber zu gewinnen, wie die Fadenschar auf den Materialträger aufgewickelt worden ist. Beispielsweise ist es möglich, den tatsächlichen Versatz des Materialträgers pro Umdrehung beim Aufwickeln zu ermitteln. Diese Information kann dann in den Signaleingang eingegeben werden, so dass man beim Abwickeln den tatsächlichen Versatz, der beim Aufwickeln aufgetreten ist, berücksichtigen kann.Additionally or alternatively, it can be provided that the control device has a signal input, in the Aufwickelinformationen the material carrier can be entered. In some cases, it is possible to gain information about how the yarn sheet has been wound onto the material carrier when winding up the yarn sheet on the material carrier. For example, it is possible to determine the actual offset of the material carrier per revolution during winding. This information can then be input to the signal input, so that when unwinding, one can take into account the actual offset that has occurred during winding.

Hierbei ist bevorzugt, dass der Signaleingang eine Datenträger-Lesevorrichtung aufweist. In diesem Fall kann man einen Datenträger verwenden, der beim Aufwickeln der Fadenschar auf den Materialträger erzeugt worden ist und der mit dem Materialträger mitgeliefert wird. Dieser Datenträger enthält dann die Aufwickelinformationen, die man beim Abwickeln wieder berücksichtigen kann.It is preferred that the signal input has a data carrier reading device. In this case, you can use a disk that has been created when winding the yarn sheet on the material carrier and is supplied with the material carrier. This disk then contains the Aufwickelinformationen that you can consider when unwinding again.

Alternativ oder zusätzlich kann vorgesehen sein, dass der Signaleingang eine Netzwerkverbindung aufweist. Diese Netzwerkverbindung kann zu einem lokalen Netzwerk oder auch zum Internet bestehen. Über die Netzwerkverbindung lässt sich die Vorrichtung mit Informationen aus einem zentralen Rechner versorgen, der seinerseits wiederrum Informationen aus dem Aufwickelvorgang speichert.Alternatively or additionally, it can be provided that the signal input has a network connection. This network connection can be to a local network or to the Internet. Via the network connection, the device can be supplied with information from a central computer, which in turn stores information from the rewinding process.

In einer alternativen oder zusätzlichen Ausgestaltung kann vorgesehen sein, dass die Steuereinrichtung mit mindestens einem Sensor verbunden ist, der eine Ist-Randposition der Fadenschar ermittelt, wobei die Steuereinrichtung den Verlagerungsantrieb so steuert, dass die Ist-Randposition mit einer Soll-Randposition übereinstimmt. Ein derartiger Sensor oder derartige Sensoren sind insbesondere dann sinnvoll, wenn die Information über das Verhalten der Fadenschar beim Aufwickeln nicht zur Verfügung steht. Die Position des Sensors oder der Sensoren ist dabei vorzugsweise möglichst dicht am Materialträger, so dass man sehr schnell in der Lage ist, den Materialträger quer zur Prozessrichtung zu verlagern, wenn sich eine Abweichung der Ränder der Fadenschar von der gewünschten Position ergibt.In an alternative or additional embodiment it can be provided that the control device is connected to at least one sensor which determines an actual edge position of the yarn sheet, the control device controls the displacement drive so that the actual edge position coincides with a desired edge position. Such a sensor or such sensors are particularly useful if the information on the behavior of the yarn sheet during winding is not available. The position of the sensor or the sensors is preferably as close as possible Material carrier, so that one is very quickly able to shift the material carrier transversely to the process direction, if there is a deviation of the edges of the yarn sheet from the desired position.

Vorzugsweise weist der Materialträger eine konische Seitenscheibe auf. Dies hat den Vorteil, dass man den Wickel der Fadenschar unmittelbar in einer Konusschärmaschine erzeugen kann und das Umbäumen der Fadenschar von einer Schärtrommel auf einen Kettbaum entfällt. Die konische Seitenscheibe dient dabei als Anlagefläche für einen axialen Rand des Fadenwickels. Beim Erzeugen des Fadenwickels auf den Materialträger ergibt sich dann auf der von der konischen Seitenscheibe abgewandten Stirnseite des Fadenwickels eine entsprechende konische Ausbildung, die verhindert, dass an dieser freien Seite Fäden von dem sich bildenden Fadenwickel herunterfallen. Beim Abwickeln der Fadenschar von dem Materialträger kann man dann den Materialträger so quer zur Prozessrichtung verlagern, dass die Konusform der Seitenscheibe nachgefahren wird.Preferably, the material carrier has a conical side window. This has the advantage that you can produce the winding of the flock of threads directly in a Konusschärmaschine and repositioning the yarn sheet of a warping drum on a warp beam accounts. The conical side plate serves as a contact surface for an axial edge of the thread winding. When producing the thread winding on the material carrier then results on the side facing away from the conical side plate end face of the thread winding, a corresponding conical design that prevents fall on this free side threads of the forming filament winding. When unwinding the yarn sheet of the material carrier can then move the material carrier so transversely to the process direction that the conical shape of the side window is traced.

In einer alternativen Ausgestaltung kann vorgesehen sein, dass der Materialträger eine Kreuzspulwicklung aufweist. Bei einer Kreuzspulwicklung sind die Fäden der Fadenschar mit vielen Richtungsänderungen parallel zur Rotationsache des Materialträgers aufgewickelt. Auch dies verhindert, dass Fäden an den Stirnseiten des Fadenwickels auf den Materialträger herunterfallen.In an alternative embodiment it can be provided that the material carrier has a cheese winding. In a cheese winding, the yarns of the yarn sheet are wound with many changes in direction parallel to the axis of rotation of the material carrier. This also prevents threads fall down on the front sides of the thread winding on the material carrier.

Die Aufgabe wird bei einem Verfahren der vorgangsgenannten Art dadurch gelöst, dass man den Materialträger beim Abziehen der Fadenschar gesteuert quer zur Prozessrichtung verlagert.The object is achieved in a method of the type mentioned process in that one moves the material carrier controlled when removing the yarn sheet transverse to the process direction.

Durch die Verlagerung des Materialträgers kann man erreichen, dass die Fadenschar immer in einen vorbestimmten breiten Bereich quer zur Prozessrichtung geführt wird. Mit anderen Worten folgen die seitlichen Ränder oder Kanten der Fadenschar immer einer vorbestimmten Position. Kantenfehler in einem mit Hilfe der Fadenschar gebildeten textilen Flächengebilde werden dadurch vermieden. Gleichwohl kann man bei der Herstellung des Materialträgers mit einem geringeren Aufwand auskommen, weil es nicht mehr so wichtig, wie bisher, ist, ob die Fäden der Fadenschar alle an einer gewünschten Position liegen.Due to the displacement of the material carrier, it can be achieved that the group of threads is always in a predetermined wide range transverse to Process direction is performed. In other words, the lateral edges or edges of the yarn sheet always follow a predetermined position. Edge defects in a textile fabric formed with the aid of the yarn sheet are thereby avoided. However, you can get along in the production of the material carrier with less effort, because it is no longer as important as before, whether the threads of the yarn sheet are all at a desired position.

Vorzugsweise ermittelt man beim Abziehen der Fadenschar vom Materialträger die Umdrehungen des Materialträgers. Wenn man beim Aufwickeln der Fadenschar auf den Materialträger eine Verlagerung parallel zur Rotationsache des Materialträgers nach einer gewissen Gesetzmäßigkeit vorgenommen hat, dann kann man beim Abwickeln der Fadenschar von dem Materialträger diese Gesetzmäßigkeit wieder rückwärts abfahren. Die einzige Information die hierfür erforderlich ist, ist die jeweils durchgeführte Anzahl von Umdrehungen des Materialträgers.Preferably, the revolutions of the material carrier are determined during the removal of the group of threads from the material carrier. If you made a shift parallel to the axis of rotation of the material carrier according to a certain law when winding the yarn sheet on the material carrier, then you can descend this law backwards when unwinding the group of threads of the material carrier. The only information required for this is the number of revolutions of the material carrier carried out in each case.

Vorzugsweise verwendet man zur Steuerung der Verlagerung des Materialträgers Informationen, die man beim Aufwickeln des Materialträgers ermittelt hat. Damit schließt man Fehler aus, die sich dadurch ergeben könnten, dass die Gesetzmäßigkeit beim Aufwickeln nicht vollständig erfüllt worden ist. Durch die beim Aufwickeln des Materialträgers gewonnenen Informationen hat man die tatsächlichen Verhältnisse festgehalten, die dann beim Abwickeln wieder Berücksichtigung finden können.Preferably used to control the displacement of the material carrier information that has been determined when winding the material carrier. This excludes errors that could result from the fact that the law has not been fully complied with winding. Due to the information obtained during winding of the material carrier, the actual conditions have been recorded, which can then be considered again during unwinding.

Vorzugsweise ermittelt man eine Ist-Randposition der Fadenschar und steuert die Verlagerung des Materialträgers so, dass die Ist-Randposition der Fadenschar mit einer Soll-Randposition der Fadenschar übereinstimmt. Dies empfiehlt sich insbesondere dann, wenn die Information über das Aufwickeln der Fadenschar auf den Materialträger nicht oder nicht in vollem Umfang zur Verfügung steht.Preferably, one determines an actual edge position of the yarn sheet and controls the displacement of the material carrier so that the actual edge position of the yarn sheet coincides with a desired edge position of the yarn sheet. This is particularly recommended when the information about the winding of the group of threads on the material carrier is not or not fully available.

Vorzugsweise verwendet man einen Materialträger mit einer konischen Seitenscheibe. Wie oben ausgeführt, kann man einen derartigen Materialträger unmittelbar an einer Schärmaschine erzeugen. Ein Umbäumvorgang ist dann nicht mehr erforderlich, was in erheblichem Umfang kosten spart.Preferably, a material carrier with a conical side window is used. As stated above, one can produce such a material carrier directly on a warping machine. A Umbäumvorgang is then no longer necessary, which saves considerable costs.

In einer alternativen Ausgestaltung kann man einen Materialträger mit einer Kreuzspulwicklung verwenden. Auch hier kann man den Materialträger unmittelbar erzeugen, ohne dass man ein Umbäumen oder Umwickeln vornehmen muss. Die Fäden der Fadenschar sind in ausreichender Weise vor einem Herabfallen geschützt.In an alternative embodiment, one can use a material carrier with a cheese winding. Again, you can produce the material carrier directly, without having to make a Umbäumen or wrapping. The threads of the group of threads are adequately protected against falling.

Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigt die

Eine Vorrichtung 1 zum Veredeln einer Fadenschar 2 weist einen Prozessabschnitt 3 auf, der beispielsweise als Vorrichtung zum Auftragen einer Schlichte auf die Fadenschar ausgebildet ist.A device 1 for refining a yarn sheet 2 has a process section 3, which is formed, for example, as a device for applying a size to the yarn sheet.

Die Vorrichtung 1 kann in gleicher Weise auch zum Verarbeiten einer Fadenschar zu einem Flächengebilde dienen, wenn der Prozessabschnitt 3 als Webmaschine oder dergleichen ausgebildet ist.The device 1 can also serve to process a group of threads into a fabric in the same way if the process section 3 is designed as a loom or the like.

Die Fadenschar 2 ist auf einem Materialträger 4 aufgewickelt.The yarn sheet 2 is wound on a material carrier 4.

Der Materialträger 4 weist einen zylindrischen Abschnitt 5 und eine konische Seitenscheibe 6 auf. Ein Fadenwickel 7, der gestrichelt dargestellt ist, um eine Situation beim Beginn eines Abwickelvorgangs zu zeigen, liegt an der konische Seitenscheibe 6 an. Der Fadenwickel 7 hat dann eine entsprechend konische Stirnseite 8.The material carrier 4 has a cylindrical portion 5 and a conical side window 6. A thread winding 7, which is shown in dashed lines to show a situation at the beginning of a unwinding, abuts against the conical side window 6. The filament winding 7 then has a corresponding conical end 8.

Dies hat zur Folge, dass die Fäden 9 der Fadenschar 2 nicht jeweils senkrecht zu einer Rotationsachse 10 des Materialträgers 4 übereinanderliegen, sondern jeder Faden 9 praktisch so gewickelt ist, dass er dem Verlauf der konischen Seitenscheibe 6 folgt.This has the consequence that the threads 9 of the yarn sheet 2 are not each perpendicular to a rotation axis 10 of the material carrier 4 superposed, but each thread 9 is practically wound so that it follows the course of the conical side window 6.

Um beim Abwickeln der Fadenschar 2 vom Materialträger 4 dennoch zu gewährleisten, dass die Fadenschar 2 genau den Verlauf einhält, der für das Einlaufen in den Prozessabschnitt 3 erforderlich ist, ist der Materialträger 4 in einer Aufnahme 11 angeordnet, die quer zur Prozessrichtung, also parallel zur Richtung der Rotationsachse 10, verlagerbar ist. Eine derartige Verlagerung wird durch einen Verlagerungsantrieb 12 bewirkt. Eine durch den Verlagerungsantrieb 12 bewirkte Verlagerungsbewegung ist durch einen Doppelpfeil 13 dargestellt. Die Aufnahme 11 bildet einen Teil einer Abwickelstation.In order to still ensure the unwinding of the yarn sheet 2 from the material carrier 4 that the yarn sheet 2 exactly complies with the course that is required for entry into the process section 3, the material carrier 4 is arranged in a receptacle 11, which is transverse to the process direction, ie parallel to the direction of the axis of rotation 10, is displaceable. Such displacement is effected by a displacement drive 12. A displacement movement effected by the displacement drive 12 is represented by a double arrow 13. The receptacle 11 forms part of an unwinding station.

Die Aufnahme 11 ist hier aus Gründen der Einfachheit als getrenntes Element dargestellt. Der Begriff "Aufnahme" ist hier allerdings funktional zu verstehen. Mit anderen Worten ist der Materialträger 4 so gelagert, dass er von dem Verlagerungsantrieb 12 parallel zu seiner Rotationsachse 10 verlagert werden kann. Der Materialträger 4 kann beispielsweise auch innerhalb der Aufnahme 11 verlagert werden, wenn die Aufnahme 11 entsprechend verlagerbare Träger oder dergleichen für den Materialträger 4 aufweist.The receptacle 11 is shown here for reasons of simplicity as a separate element. However, the term "recording" is understood here to be functional. In other words, the material carrier 4 is mounted so that it can be displaced by the displacement drive 12 parallel to its axis of rotation 10. The material carrier 4 can also be displaced, for example, within the receptacle 11 when the receptacle 11 has correspondingly displaceable carriers or the like for the material carrier 4.

Die Aufnahme 11 kann in nicht näher dargestellter Weise auch nur einen Rotationsantrieb für den Materialträger 4 aufweisen.The receptacle 11 may also have only a rotary drive for the material carrier 4 in a manner not shown.

Die Abwickelstation kann auch integraler Bestandteil des Prozessabschnitts 3 oder dessen Gehäuses sein oder die Abwickelstation und der Prozessabschnitt 3 können in einer Baugruppe zusammen gefasst werden.The unwind station may also be an integral part of the process section 3 or its housing, or the unwind station and the process section 3 may be grouped together in an assembly.

Die Aufnahme 11 weist einen Umdrehungszähler 14 auf, der die Anzahl der Umdrehungen des Materialträgers 4 ermittelt. Der Umdrehungszähler 14 ist mit einer Steuereinrichtung 15 verbunden, die wiederrum den Verlagerungsantrieb 12 steuert.The receptacle 11 has a revolution counter 14, which determines the number of revolutions of the material carrier 4. The revolution counter 14 is connected to a control device 15, which in turn controls the displacement drive 12.

Wenn man beim Aufwickeln der Fadenschar 2 auf den Materialträger 4 eine gewisse Gesetzmäßigkeit befolgt hat, dann reicht in vielen Fällen eine Information über die durchgeführten Umdrehungen des Materialträgers 4 beim Abwickeln aus, um diese Gesetzmäßigkeit, also eine beim Aufwickeln durchgeführte Bewegung des Materialträgers parallel zur Rotationsachse 10, wieder rückwärts abzufahren.If one has followed a certain legality when winding the yarn sheet 2 on the material carrier 4, then in many cases information about the performed revolutions of the material carrier 4 during unwinding to this law, ie a carried out during winding movement of the material carrier parallel to the axis of rotation 10, back off again.

In vielen Fällen ist aber eine genauere Steuerung dann möglich, wenn man eine Information über das Aufwickeln der Fadenschar 2 auf den Materialträger 4 ermittelt und diese Information jedem Materialträger 4 mit der aufgewickelten Fadenschar 2 zuordnet. Diese Zuordnung kann beispielsweise dadurch erfolgen, dass man einen Datenträger erzeugt, auf dem das Aufwickelverhalten des Materialträgers 4 gespeichert worden ist, und diesen Datenträger gemeinsam mit dem fertig aufgewickelten Materialträger 4 versendet. Der Datenträger kann dann in einen Signaleingang 16 der Steuereinrichtung 15 eingelesen werden, so dass die Information über das Aufwickeln beim Abwickeln der Fadenschar 2 wieder zur Verfügung steht.In many cases, however, a more accurate control is possible if one determines information about the winding of the yarn sheet 2 on the material carrier 4 and this information assigns each material carrier 4 with the wound yarn sheet 2. This assignment can be effected, for example, by producing a data carrier on which the winding behavior of the material carrier 4 has been stored, and sending this data carrier together with the finished wound-up material carrier 4. The data carrier can then be read into a signal input 16 of the control device 15, so that the information about the winding when unwinding the yarn sheet 2 is available again.

Alternativ dazu kann man die Information über das Aufwickeln auch ohne Datenträger übertragen, beispielsweise durch ein Netzwerk, wie ein lokales Netzwerk (LAN) oder auch das Internet. In diesem Fall weist der Signaleingang 16 eine Netzwerkverbindung auf.Alternatively, you can transfer the information about the winding without media, for example, through a network, such as a local area network (LAN) or the Internet. In this case, the signal input 16 has a network connection.

Zusätzlich oder alternativ können auch ein oder zwei (oder mehr) Sensoren 17, 18 vorgesehen sein, die ebenfalls mit der Steuereinrichtung 15 verbunden sind. Die Sensoren 17, 18 ermitteln eine Ist-Position von Randfäden 19, 20 der Fadenschar. Diese Ist-Position wird verglichen mit einer Soll-Position, die beispielsweise durch den Prozessabschnitt 3 vorgegeben ist. Die Steuereinrichtung 15 kann dann den Verlagerungsantrieb 12 so betätigen, dass er den Materialträger so versetzt, dass die Ist-Position der Randfäden 19, 20 wieder mit ihrer Soll-Position übereinstimmt. Die Position der Randfäden 19, 20 wird auch kurz als "Randposition" bezeichnet.Additionally or alternatively, one or two (or more) sensors 17, 18 may be provided, which are also connected to the control device 15. The sensors 17, 18 determine an actual position of edge threads 19, 20 of the yarn sheet. This actual position is compared with a desired position, which is predetermined for example by the process section 3. The control device 15 can then actuate the displacement drive 12 so that it displaces the material carrier so that the actual position of the edge threads 19, 20 again coincides with its desired position. The position of the edge threads 19, 20 is also referred to as "edge position" for short.
