Description

Die Erfindung bezieht sich auf eine Schäranlage mit einer eine drehbare Trommel aufweisenden Konusschärmaschine und mit einem Spulengatter, das eine Vielzahl von Fadenabzugsstellen aufweist, von denen eine Schar von Fäden abgezogen und in Form nacheinander gelegter Bandwickel auf die Trommel aufgewickelt wird, sowie auf ein Schärverfahren, bei dem eine Schar von Fäden von einem Spulengatter abgezogen und in Form nacheinander gelegter Bandwickel auf die Trommel einer Konusschärmaschine aufgewickelt wird.The invention relates to a sewage treatment plant with a rotary drum having a cone warping machine and with a creel having a plurality of thread take-off points, of which a group of threads is withdrawn and wound up in the form of successively placed tape roll on the drum, and to a warping method, in which a bevy of threads is withdrawn from a creel and wound in the form of successively placed tape roll on the drum of a cone warping machine.

Als Stand der Technik wird auf DE 37 33 692 A1 verwiesen.As the prior art reference is made to DE 37 33 692 A1.

Konusschärmaschinen werden hauptsächlich zur Herstellung von Musterketten oder Kurzketten eingesetzt, können aber auch Produktionsketten erzeugen. Die Bänder, welche die Bandwickel bilden, sind einander gleich und entsprechen dem Rapport. Sie werden von denselben Spulen des Gatters abgezogen. Bei großen Fadenzahlen im Rapport benötigt man eine große Spulenanzahl und entsprechend große Spulengatter mit einer großen Zahl an Spulenaufsteckungen. Aus diesem Grund sind große Produktionsflächen in der Schärerei erforderlich.Cone crushers are mainly used for the production of pattern chains or short chains, but can also produce production chains. The bands that form the band wraps are equal to each other and correspond to the repeat. They are from the same coils of the gate deducted. For large numbers of threads in rapport you need a large number of spools and correspondingly large creels with a large number of Spulenaufsteckungen. For this reason, large production areas are needed in the sharpening.

DE 728 460 C beschreibt ein Verfahren und eine Vorrichtung zum gruppenweisen Auswechseln von Spulen an Gattern. Mehrere Spulen sind an einer Spulenhalterung übereinander angeordnet, wobei von jeder Spule ein Faden abgezogen und einer Fadenabzugsstelle zugeführt wird. Mit Hilfe einer Trenneinrichtung, die auf einem Wagen bewegbar ist, können die Fäden aller übereinander angeordneten Spulen gleichzeitig durchtrennt werden. Nach dem Aufstecken neuer Spulen werden die in den Fadenabzugsstellen gehaltenen Fadenenden mit den Fadenanfängen der neuen Spulen verknüpft.DE 728 460 C describes a method and a device for the group-wise replacement of coils on gates. A plurality of bobbins are arranged one above the other on a bobbin holder, wherein a thread is taken from each bobbin and fed to a thread withdrawal point. With the help of a separating device which is movable on a carriage, the threads of all superimposed coils can be cut simultaneously. After attaching new coils held in the thread withdrawal points yarn ends are linked to the thread beginnings of the new coil.

Der Erfindung liegt die Aufgabe zugrunde, beim Schären auf einer Konusschärmaschine die Voraussetzungen dafür zu schaffen, daß bei der Rapportbildung eine größere Freizügigkeit gegeben ist.The invention has for its object to provide the conditions for archiving on a cone warping machine that in the rapport formation greater freedom of movement is given.

Diese Aufgabe wird konstruktiv dadurch gelöst, daß das Spulengatter ein Wechselgatter ist, bei dem zum Ändern einer Fadenfolge zwischen zwei Bandwickeln jeweils einer Fadenabzugsstelle zwei oder mehr Spulenaufsteckungen zugeordnet sind, die wahlweise in eine Arbeitsstellung bringbar sind, und daß eine Schneidvorrichtung zum Abtrennen des Fadens von einer Spule und eine Verbindungsvorrichtung zum Verbinden dieses Fadens mit einer anderen Spule vorgesehen ist.This object is achieved constructively in that the creel is a change gate, in which for changing a thread sequence between two tape reels each have a Fadenabzugsstelle two or more Spulenaufsteckungen are assigned, which can be selectively brought into a working position, and that a cutting device for separating the thread of a coil and a connecting device for connecting this thread is provided with another coil.

Immer dann, wenn auf der Konusschärmaschine ein Bandwickel fertiggestellt ist, kann die Fadenfolge im nächsten Bandwickel geändert werden. Dies ermöglicht es, größere Rapporte mit Hilfe von zwei oder mehr Bändern zu erzeugen, deren Fadenanzahl geringer ist als diejenige des Rapports. Daher kann die vom Spulengatter eingenommene Fläche kleiner als bisher gehalten werden. Es können auch Bänder gewickelt werden, deren Fadenanzahl größer als die Fadenanzahl des Rapports ist. Die den Rapport übersteigenden Fäden des Bandes dienen dann bereits als erster Teil des nächsten Rapports, der auf dem zweiten Band fortgesetzt wird. Dies steigert die Produktivität der Konusschärmaschine. Darüber hinaus gibt es noch weitere Vorteile, weil der Schärarbeitsgang auch voll automatisiert werden kann. Komplizierte und aufwendige Muster, wie sie bei Schablonen oder Kurzketten üblich sind, lassen sich auf einfachere Weise als bisher erzeugen.Whenever a band wrap is completed on the cone warper, the thread sequence can be used in the next Tape wraps are changed. This makes it possible to produce larger repeats by means of two or more bands whose number of threads is less than that of the repeat. Therefore, the area occupied by the creel can be kept smaller than heretofore. It can also be wound tapes whose number of threads is greater than the number of threads of the repeat. The threads of the band exceeding the repeat will serve as the first part of the next rapport, which will be continued on the second band. This increases the productivity of the cone warping machine. In addition, there are other advantages, because the sharpening process can also be fully automated. complicated and elaborate patterns, such as are common in stencils or short chains, can be produced in a simpler manner than before.

Günstig ist es, daß einer einen Wechsel erlaubenden Fadenabzugsstelle mindestens sechs Spulenaufsteckungen zugeordnet sind. Da eine Ware in der Regel nicht mehr als sechs unterschiedliche Fadenarten, insbesondere unterschiedliche Farben, aufweist, genügen diese sechs Spulen. Darüber hinaus vorgesehene Spulenaufsteckungen ermöglichen es dann, größere Längen mindestens einer Fadenart vorrätig zu halten.It is favorable that at least six Spulenaufsteckungen are assigned to a change-permitting yarn withdrawal point. Since a product usually has no more than six different types of yarn, in particular different colors, these six coils are sufficient. In addition provided Spulenaufsteckungen then make it possible to keep greater lengths of at least one type of thread in stock.

Empfehlenswert ist es, daß das Spulengatter mindestens 64 einen Wechsel erlaubende Fadenabzugsstellen aufweist. Es können daher gleichzeitig 64 Fäden im Band verarbeitet werden. Diese Fadenanzahl läßt sich erhöhen, beispielsweise im Baukastenprinzip durch je 16 Fadenabzugsstellen aufweisende Einheiten.It is recommended that the creel has at least 64 a thread changing points allowing change. It can therefore simultaneously 64 threads are processed in the tape. This number of threads can be increased, for example, in the modular principle by 16 thread withdrawal units each having units.

Vorzugsweise ist dafür gesorgt, daß die einer Fadenabzugsstelle zugeordneten Spulenaufsteckungen auf einem Förderer angeordnet sind und durch Versatz des Förderers in die Nähe der Fadenabzugsstelle gelangen. Ein solcher Förderer ermöglicht es, rasch die gewünschte Spule in die Arbeitsstellung zu bringen.Preferably, it is ensured that the Fadenaufzugsstelle associated Spulenaufsteckungen are arranged on a conveyor and reach by displacement of the conveyor in the vicinity of the thread take-off point. Such a conveyor makes it possible to quickly bring the desired coil in the working position.

Vorzugsweise sind die Förderer motorisch positionierbar sind. Der Spulenwechsel läßt sich daher automatisieren.Preferably, the conveyors are motorized positionable. The bobbin change can therefore be automated.

Dies gilt insbesondere dann, wenn jeder Förderer einen eigenen Motor besitzt.This is especially true if each conveyor has its own engine.

Konstruktiv gibt es einen geringen Aufwand, wenn die Schneid- und Verbindungsvorrichtung als Wandervorrichtung ausgelegt und mehreren Fadenabzugsstellen zugeordnet ist.Structurally, there is little effort when the cutting and connecting device as a traveling device designed and assigned to multiple thread withdrawal points.

Eine bevorzugte Alternative sieht vor, daß jeder Fadenabzugsstelle eine eigene Schneid- und Verbindungsvorrichtung zugeordnet ist. Auf diese Weise ergibt sich ein sehr rascher Spulenwechsel.A preferred alternative provides that each thread take-off point is assigned its own cutting and connecting device. In this way results in a very fast bobbin change.

Günstig ist es auch, daß dem Förderer mindestens eine zusätzliche zweite Fadenabzugsstelle zugeordnet ist. Das Gatter kann daher wahlweise als Wechselgatter oder als Gatter mit einer außerordentlich großen Anzahl von Fadenabzugsstellen verwendet werden.It is also favorable that the conveyor is assigned at least one additional second thread withdrawal point. The gate can therefore be used either as a change gate or as a gate with an extremely large number of thread take-off points.

Vorzugsweise ist der Förderer ein Drehtisch. Viele solcher Drehtische lassen sich platzsparend übereinander anordnen.Preferably, the conveyor is a turntable. Many such rotary tables can be arranged one above the other to save space.

Eine Alternative besteht darin, daß jeder Förderer ein vertikal umlaufender Bandförderer ist. Solche Bandförderer können platzsparend hintereinander angeordnet werden.An alternative is that each conveyor is a vertical belt conveyor. Such belt conveyors can be arranged to save space in a row.

Des weiteren empfiehlt sich ein Prozeßrechner, der das Schneiden der Fäden, das Positionieren anderer Spulenaufsteckungen in der Nähe der zugehörigen Fadenabzugsstellen und das Verbinden der Fäden automatisch steuert. Dieser Prozeßrechner ermöglicht ein automatisches Arbeiten der Schäranlage.Furthermore, a process computer is recommended, which automatically controls the cutting of the threads, the positioning of other Spulenpsteckungen near the associated Fadenabzugsstellen and connecting the threads. This process computer allows automatic operation of the sewage treatment plant.

Günstig ist es, daß ein Prozeßrechner aus den Daten des Schärbriefs berechnet, welche Spulenaufsteckung mit einer Spule welcher Fadenart zu versehen ist. Der Rechner vermag daher die optimale Bestückung der Spulenaufstekkungen zu ermitteln.It is favorable that a process computer calculates from the data of the scrawl letter which coil attachment is to be provided with a coil of which type of thread. The computer can therefore determine the optimal placement of Spulenaufstekkungen.

Von Vorteil ist es, daß am Förderer eine optische Anzeige vorgesehen ist, die die Fadenart der jeweils aufzusteckenden Spule und/oder die Spulenaufsteckungen, die mit einer bestimmten Fadenart bestückt werden sollen, anzeigt. Dies erleichtert die Bestückung der Spulenaufsteckungen.It is advantageous that an optical display is provided on the conveyor, which indicates the type of thread of each aufzusteckenden coil and / or the Spulenaufsteckungen that are to be populated with a certain type of thread. This facilitates the placement of the Spulenaufsteckungen.

In verfahrenstechnischer Hinsicht besteht die Lösung der Aufgabe darin, daß nach Fertigstellung eines Bandwickels zumindest ein Teil der Fäden von den zugehörigen Spulen abgeschnitten und durch Verbindungsstellen, wie Knoten oder Spleißungen, mit jeweils einer anderen Spule verbunden wird, wobei jeder Fadenabzugsstelle mindestens zwei Spulenaufsteckungen zugeordnet werden. Auf diese Weise ergibt sich die gewünschte Musterung.In procedural terms, the solution to the problem is that after completion of a tape winding at least a portion of the threads cut from the associated coils and connected by junctions, such as knots or splices, each with a different coil, each Fadenabzugsstelle be assigned at least two Spulenaufsteckungen , In this way, the desired pattern results.

Hierbei empfiehlt es sich, daß die Fadenanzahl bei allen Bändern mit Ausnahme des Restbandes gleich ist. Die Fadenanzahl kann unabhängig von der Fadenanzahl des Rapports oder ihr gleich sein.Here it is recommended that the number of threads in all bands is the same except for the remaining band. The number of threads can be equal to or equal to the number of threads in the repeat.

Von Vorteil ist es, daß zur Bildung des Restbandes der nicht benötigte Teil der Förderer von den zugehörigen Spulen abgeschnitten bleibt. Die Schneidvorrichtung wird daher zur Festlegung der Größe des Restbandes genutzt.It is advantageous that the unneeded part of the conveyor remains cut off from the associated coils to form the residual band. The cutting device is therefore used to determine the size of the residual band.

Von Vorteil ist es auch, daß mehrere Bandwickel mit gleicher Gesamtfadenzahl, Garn-Nummer, Fäden/cm und Kettbreite, aber unterschiedlichen Farben, in einem Schärdurchgang nacheinander erzeugt werden. Auf diese Weise lassen sich in der geschärten Kette nebeneinander mehrere nur geringfügig voneinander abweichende Schablonen u.dgl. erzeugen.It is also advantageous that several tape rolls with the same total number of threads, yarn number, threads / cm and warp width, but different colors, are generated in a warping passage in succession. In this way, in the hardened chain next to each other several only slightly different templates and the like. produce.

Die veranschaulichte Schäranlage weist eine Konusschärmaschine 1 auf, deren Trommel 2 mit einem Konus 3 versehen ist. Vorgeschaltet ist ein Einlaufriet 4 und eine automatische Kreuzlegeeinrichtung 5, über die eine Vielzahl von Fäden 6 in Form eines Bandes 7 zugeführt wird. Auf der gegenüberliegenden Seite befindet sich eine Bäummaschine 8, auf die die auf der Konusschärmaschine 1 erzeugte Kette umgebäumt werden kann. All dies entspricht dem üblichen Aufbau einer Konusschäranlage.The illustrated sewage treatment plant has a cone warping machine 1, the drum 2 is provided with a cone 3. An infeed reed 4 and an automatic cross-laying device 5, via which a multiplicity of threads 6 in the form of a strip 7 are fed, are connected in front. On the opposite side is a boom machine 8, on which the chain generated on the cone warping machine 1 can be folded. All this corresponds to the usual construction of a cone water treatment plant.

Die Fäden 6 kommen von einem Spulengatter 9, das als Wechselgatter ausgelegt ist. Zu diesem Zweck sind an Förderern 10 in Form von Drehtischen je neun Spulenaufsteckungen 11 angebracht, die je eine Spule 12 tragen. Jeweils eine der Spulen 12 befindet sich in der Arbeitsstellung 13, in der die Spule einer FadenabzugsStelle 14 benachbart ist. Diese Fadenabzugsstelle 14 ist an der Innenseite des Gattergestells 15 vorgesehen. Die Fäden 6 werden von der Fadenabzugsstelle 14 über Fadenbremsen 16 mit Fadenbruchüberwachung zum Einlaufriet 4 geleitet. Jeder Förderer 10 ist durch einen eigenen Motor 17 mit Positionsrückmeldung derart positionierbar, daß jeweils eine ausgewählte Spule sich in der Arbeitsstellung 13 befindet. Im Gattergestell 15 sind jeweils acht derartige Drehtische 10 übereinander angeordnet. Es sind acht derartige Stapel vorgesehen, so daß insgesamt 64 Fadenabzugsstellen 14 vorhanden sind. Durch Angliederung weiterer Baueinheiten kann die Zahl der Fadenabzugsstellen 14 noch erhöht werden, beispielsweise um jeweils sechzehn Fadenabzugsstellen pro Baueinheit.The threads 6 come from a creel 9, which is designed as a change gate. For this purpose, nine bobbin suspensions 11 are mounted on conveyors 10 in the form of rotary tables, each carrying a coil 12. In each case one of the coils 12 is in the working position 13, in which the coil of a yarn withdrawal point 14 is adjacent. This thread withdrawal point 14 is provided on the inside of the gate frame 15. The threads 6 are transferred from the thread withdrawal point 14 Thread brakes 16 with yarn breakage monitoring to inlet reel 4 passed. Each conveyor 10 can be positioned by a separate motor 17 with position feedback such that in each case a selected coil is in the working position 13. In the gate frame 15 eight such turntables 10 are arranged one above the other. There are eight such stacks provided, so that a total of 64 thread take-off points 14 are present. By adding further units, the number of thread withdrawal points 14 can be increased even further, for example by sixteen thread withdrawal points per unit.

Zum Spulengatter 9 gehört eine automatische Schneid- und Verbindungsvorrichtung 18, die aus zwei gleichartigen Teilen besteht und an den Fadenabzugsstellen 14 vorbeigeführt werden kann. Mit der Schneidvorrichtung wird ein Faden 6 von der zugehörigen Spule 12 abgetrennt. Mit der Verbindungsrichtung wird der genannte Faden mit einer anderen Spule 12 verbunden. Saugrüssel 19 halten hierbei den abgeschnittenen Faden fest, bis er wieder neu mit einer anderen Spule verbunden ist.The creel 9 includes an automatic cutting and connecting device 18, which consists of two similar parts and can be moved past the thread withdrawal points 14. With the cutting device, a thread 6 is separated from the associated coil 12. With the connection direction of said thread is connected to another coil 12. Suction probes 19 hold the cut thread until it is reconnected to another spool.

Die Verbindungsvorrichtung kann als Knotvorrichtung ausgebildet sein, aber auch als Spleißvorrichtung, Klebevorrichtung u.dgl. Für jede horizontale Reihe von Fadenabzugsstellen 14 ist daher eine Einheit der kombinierten Schneid- und Verbindungsvorrichtung 18 vorgesehen.The connecting device may be formed as a knotting device, but also as a splicing device, adhesive device and the like. For each horizontal row of thread take-off points 14, therefore, a unit of the combined cutting and connecting device 18 is provided.

Ein Prozeßrechner 20 steuert, wenn erforderlich, die Betätigung der Schneid- und Verbindungsvorrichtung 18 sowie das Positionieren der Drehtische, sobald der Bandwickel aus dem Band 7 der Fäden 6 auf der Konusschärmaschine 1 fertiggestellt ist. Als zweite Aufgabe übernimmt der Prozeßrechner das Festlegen, welche der verschiedenen Fadenarten zugeordneten Spulen 12 vor Beginn auf welche Spulenaufsteckung gebracht werden muß. Zur Erleichterung des Aufbringens der Spulen 12 besitzt jeder Drehteller eine optische Anzeige 21, z.B. eine Kontrollampe. Der Prozeßrechner 20 rechnet aus, welche der vielen Spulenaufsteckungen 11 mit Spulen 12 ein und desselben Fadenmaterials bestückt werden müssen. Diese Aufsteckungen werden durch die Kontrollampe 21 nacheinander angezeigt. Eine andere optische Anzeige 22, z.B. ein Display, kann für jede Spulenaufsteckung anzeigen, welche Farbnummer zur Bestückung herangezogen werden soll. Das veranschaulichte Spulengatter 9 hat hier 64 Fadenabzugsstellen 14. Durch Hinzunahme weiterer Einheiten, z.B. in Sechzehner-Gruppen, kann das Spulengatter so vergrößert werden, daß statt der maximal 64 Fäden im Band gleichzeitig 80, 96, 114, 128 oder mehr Einzelfäden im Band geschärt werden können.A process computer 20 controls, if necessary, the operation of the cutting and connecting device 18 and the positioning of the turntables as soon as the tape roll from the belt 7 of the threads 6 on the cone warping machine 1 is completed. As a second task accepts the process computer setting which of the different types of yarn associated coils 12 must be brought before the beginning of which Spulenstecksteckung. To facilitate the application of the coils 12, each turntable has an optical display 21, for example a warning lamp. The process computer 20 calculates which of the many Spulenaufsteckungen 11 with coils 12 one and the same thread material must be fitted. These suspensions are displayed in sequence by the indicator 21. Another optical display 22, such as a display, can indicate for each Spulenstecksteckung which color number to be used for placement. The illustrated creel 9 has here 64 Fadenabzugsstellen 14. By adding more units, eg in groups of six, the creel can be increased so that instead of the maximum of 64 threads in the same band 80, 96, 114, 128 or more individual threads in the band can be.

Für eine alternative Betriebsweise sind an der Außenseite des Gestells 15 zwei weitere Fadenabzugsstellen 23 und 24 vorgesehen, über die unter Ausnutzung der an sich zum Wechsel bestimmten Spulen 12 weitere Fäden 25 über die Fadenbremsen 26 zum Band 7 geführt werden können. Auf diese Weise kann die zu verarbeitende Fadenanzahl ohne Vergrößerung des Gatters auf 128 Fäden bzw. 192 Fäden/Rapport erhöht werden.For an alternative mode of operation, two further thread withdrawal points 23 and 24 are provided on the outer side of the frame 15, by means of which further threads 25 can be guided via the thread brakes 26 to the strip 7 by utilizing the bobbins 12 intended to be changed. In this way, the number of threads to be processed without increasing the gate can be increased to 128 threads or 192 threads / repeat.

Im Betrieb kann wie folgt vorgegangen werden. Dem Prozeßrechner 20 werden beispielsweise die folgenden Daten vorgegeben

  • Gesamtfadenzahl in der Kette
  • Fadenzahl im Band 7 (maximal 64 oder in anderen Ausbausstufen auch mehr)
  • Schärbriefdaten
  • Kettlänge einschließlich Vorlauf vor unteren Fadenteilungen und Nachlauf nach oberen Fadenteilungen
  • Zuordnung einer Farbnummer, so daß für jede der z.B. 64 Drehtische 10 die jeweilige Farbe angegeben werden kann
  • Garn-Nummer, z.B. in Nm.
During operation, the following procedure can be followed. The process computer 20, for example, the following data are given
  • Total thread count in the chain
  • Thread number in volume 7 (maximum 64 or more in other stages)
  • Schär letter data
  • Warp length including feed before lower thread pitches and caster after upper thread pitches
  • Assignment of a color number, so that for each of the example 64 turntables 10, the respective color can be specified
  • Yarn number, eg in Nm.

Der Prozeßrechner berechnet aus den obigen Parametern alle für den Produktionsprozeß benötigten Daten, wie Anzahl der Spulen/Farbe, Lauflänge und Gewicht, so daß sich eine optimale Nutzung der aufgesteckten Spulen ergibt.From the above parameters, the process computer calculates all the data required for the production process, such as the number of bobbins / color, run length and weight, so that an optimal use of the attached bobbins results.

Der Schärvorgang selbst entspricht dem bekannten Vorgehen. Es werden daher Fadenkreuzschnüre bzw. Schlichteteilungen in üblicher Weise erzeugt. Es ist darauf zu achten, daß die Verbindungsstellen, also beispielsweise die Knoten, einen festen Vorlauf haben, so daß alle Verbindungsstellen vor der ersten Fadenkreuzschnur oder der ersten Schlichteteilung liegen und den Abwebprozeß der fertigen Kette nicht beeinflussen.The warping process itself corresponds to the known procedure. Therefore, crosshair cords or sizing divisions are produced in the usual way. It is important to ensure that the joints, so for example, the nodes have a fixed lead, so that all joints are in front of the first crosshair string or the first sizing division and do not affect the Abwebprozeß the finished chain.

In Fig. 5 werden für entsprechende Teile um 100 erhöhte Bezugszeichen verwendet. Unterschiedlich ist im wesentlichen, daß die Spulenaufsteckungen 111 für die Spulen 112 an einem als Bandförderer ausgebildeten Förderer 110 befestigt sind, der die Spulen 112 zu Fadenabzugsstellen 114 transportiert, wobei jeweils vier solcher Abzugsstellen übereinander angeordnet sind. Die Betriebsweise entspricht derjenigen der Fig. 1 bis 4. Der Förderer 110 ist ein vertikal umlaufender Bandförderer, bei dem jeweils vier benachbarte Fadenabzugsstellen 114 als Arbeitsstellungen 113 vorgesehen sind. Wenn lediglich die beiden Förderer 110 der Fig. 5 vorhanden sind, hat jede Fadenabzugsstelle eine eigene Schneid- und Verbindungsvorrichtung 118.In Fig. 5 reference numerals are used for corresponding parts increased by 100. The difference is essentially that the Spulenaufsteckungen 111 are attached to the coils 112 on a designed as a belt conveyor conveyor 110, which transports the coils 112 to thread withdrawal points 114, wherein four such deduction points are arranged one above the other. The mode of operation corresponds to that of FIGS. 1 to 4. The conveyor 110 is a vertically rotating belt conveyor, in which four adjacent thread withdrawal points 114 are provided as working positions 113. If only the two conveyors 110 of FIG. 5 are present, Each thread take-off point has its own cutting and connecting device 118.
