Description

Die Erfindung betrifft das Positionieren eines Faserbandendes an einer gefüllten Flachkanne, die nach Befüllung an einer Strecke der Textilindustrie zu wechseln ist gegen eine leere Flachkanne.The invention relates to the positioning of a sliver end a filled flat jug, which after filling on a stretch The textile industry has to be replaced by an empty flat can.

Die Strecke verarbeitet Faserband und legt das Faserband in Lagen zykloidenförmig in der Flachkanne ab. Ist die Flachkanne gefüllt, wird die Flachkanne gegen eine leere gewechselt. Dazu muß das Faserband getrennt werden und das Bandende am Kannenrand der Flachkanne abgelegt werden.The line processes sliver and places the sliver in layers cycloidal in the flat can. If the flat can is filled, the flat can is exchanged for an empty one. To do this, the sliver must be separated and the end of the band at the edge of the can of the flat can be filed.

Liegt das getrennte Faserbandende an einer zufälligen Position des Kannenrandes muß es durch aufwendige, automatische Vorrichtungen gesucht werden und es kommt zu Verzögerungen bei der Positionierung der Flachkanne im Transportsystem bzw. an der Weiterverarbeitungsmaschine. Es kommt letztlich zu einer Verzögerung in der Weiterverarbeitung.If the separated sliver end is in a random position the edge of the jug it has to be through complex, automatic devices are searched for and there are delays in positioning the flat can in the transport system or on the processing machine. There is ultimately a delay in further processing.

Um diese Nachteile zu vermeiden, wurde der Einsatz einer Haltevorrichtung zur Halterung des Faserbandendes in einer definierten Position am Kannenrand vorgeschlagen. Die Haltevorrichtung ist zusätzlich am Kannenrand installiert. Das Faserbandende muß in dieser Haltevorrichtung abgelegt werden. Es ist aufwendig, stets eine zusätzliche Halterung an der Flachkanne zu verwenden und den Kannenrand so zu gestalten, daß die Haltevorrichtung installiert werden kann.To avoid these disadvantages, the use of a holding device for holding the sliver end in a defined Position suggested at the edge of the can. The holding device is additionally installed on the can rim. The sliver end must be in this holding device are stored. It is expensive, always to use an additional bracket on the flat can and the To design the can rim so that the holding device is installed can be.

Auf eine Positionierung des Faserbandendes kann jedoch nicht verzichtet werden. Das ist ein Erfordernis der Automation für nachfolgende Arbeitsschritte einer Spinnerei. Mit einer stets reproduzierbaren Position des Bandendes im Kannenrand gelingt es den Aufwand bei nachfolgenden Arbeitsschritten oder beim Ansetzen des Faserbandes an der Weiterverarbeitungsmaschine klein zu halten bzw. zu reduzieren.Positioning of the sliver end cannot be dispensed with will. This is a requirement of automation for subsequent ones Steps in a spinning mill. With an always reproducible The position of the belt end in the can edge succeeds Effort in subsequent work steps or when preparing the To keep the sliver small on the processing machine or reduce.

Könnte das Faserbandende an der Flachkanne an einer stets reproduzierbaren Position des Kannenrandes abgelegt werden, ohne daß eine zusätzliche Halterung erforderlich wäre, würde dies wesentlich zur Senkung des Aufwandes beitragen.Could the sliver end on the flat can on an always reproducible Position of the edge of the can be stored without an additional bracket would be required, this would be essential contribute to reducing the effort.

Unter diesem Gesichtspunkt gelingt es der deutschen Anmeldung P 43 24 948.5 das Faserbandende ohne Halterung am Kannenrand reproduzierbar zu positionieren. Die Positionierung des Faserbandendes an der Flachkanne wird dadurch erreicht, daß ausgehend von der Stillstandsposition der Flachkanne die Mündung des Drehtellers im Bezug auf Längsachse der Flachkanne so positioniert stillgesetzt wird, daß die Faserbandschlingen beim Verschieben der Flachkanne derart abgezogen werden, daß das Faserband am Ende des Verschiebeweges im mittleren Bereich der Stirnseite der Flachkanne zu liegen kommt und dann durch einen Trenner getrennt wird. Die befüllte Flachkanne steht in Stillstandsposition unter dem Drehteller und wird aus dieser Position verschoben, dann erst wird das Faserband getrennt. Infolge der hohen Haftreibung des Faserbandes kann es beim selbständigen Abwickeln der Faserbandschlingen zu einer Beeinflussung des abgewickelten Faserbandes kommen.From this point of view, the German application P succeeds 43 24 948.5 the sliver end can be reproduced without a holder on the edge of the can to position. The positioning of the sliver end on the flat can is achieved in that starting from the Standstill position of the flat can the mouth of the turntable in With respect to the longitudinal axis of the flat jug positioned in this way, stopped will that the sliver when moving the flat can be pulled off so that the sliver at the end of the displacement in the middle of the front of the flat can comes and is then separated by a separator. The filled The flat jug is in a standstill position under the turntable and is moved from this position, only then will that Sliver separated. As a result of the high static friction of the sliver it can happen when unwinding the slings independently an influence on the unwound sliver come.

In einer anderen Ausführungsform zur Positionierung des Bandendes wird dargestellt, daß nach Positionierung der Drehtellermündung in einer Stillstandsposition der Flachkanne zuerst das Faserband zwischen Kalanderwalzenpaar und Bandführungskanal mittels einer mechanischen Trennvorrichtung getrennt wird. Nach der Trennung wird die Flachkanne in eine Übernahmeposition verschoben. Dabei wird das getrennte Bandende aus dem Bandführungskanal gezogen und hängt an der Stirnwandung der Flachkanne an positionierter Stelle und entsprechender Länge. Aufwendig ist, daß der Positioniervorgang eine komplette Trennvorrichtung bekannter Art erfordert. Die Trennvorrichtungen haben oftmals den Nachteil, daß das Faserband während des Trennvorganges ausgelenkt wird und dann das getrennte Bandende auf dem Rand des Bandführungskanals hängt. Das behindert die Wiederinbetriebnahme der Maschine.In another embodiment for positioning the tape end it is shown that after positioning the turntable mouth in a standstill position of the flat can first the sliver between the pair of calender rolls and the belt guide channel by means of a mechanical separator is separated. After the separation the flat can is moved to a takeover position. Here the separated tape end is pulled out of the tape guide channel and hangs on the end wall of the flat jug at a positioned point and corresponding length. It is complex that the positioning process requires a complete separation device of a known type. The Separating devices often have the disadvantage that the sliver is deflected during the separation process and then the separated The tape end hangs on the edge of the tape guide channel. That hampers restarting the machine.

Ein Verfahren gemäß dem Oberbegriff des Anspruchs 1 und eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 4 sind aus der EP-A-0 574 659 bekannt.A method according to the preamble of claim 1 and one Device according to the preamble of claim 4 are from the EP-A-0 574 659 known.

Aufgabe der Erfindung ist es bei der Positionierung des Faserbandendes eine Qualitätsminderung des Faserbandes zu vermeiden und zugleich den Aufwand zur Positionierung des Bandendes an einer Flachkanne weiter zu reduzieren.The object of the invention is to position the sliver end to avoid a deterioration in the quality of the sliver and at the same time the effort to position the tape end on one To further reduce the flat can.

Mit Erreichen des Füllzustandes der Flachkanne wird deren Changierung beendet und die Lieferung des Faserbandes gestoppt. Kalanderwalzenpaar und Drehteller sind gestoppt. Die Flachkanne steht in dem Endpunkt ihrer Changierung mit einer Stirnseite unterhalb des Drehtellers. Das ist die Stillstandsposition, wo die Übergabe der Flachkanne an ein nachfolgendes Transportsystem gewährleistet ist. In dieser Stillstandsposition der Flachkanne ist die Mündung des Drehtellers positioniert, d.h. die Mündung des Drehtellers wird im Bezug auf die Stillstandsposition der Flachkanne stets in der gleichen Position stillgesetzt. Mit dieser definierten Position der Mündung des Drehtellers ist bestimmbar an welcher Position des Randes der Stirnwandung der Flachkanne das Faserbandende abgelegt werden wird.When the flat can reaches its filling level, it changes finished and the delivery of the sliver stopped. Pair of calender rolls and the turntable are stopped. The flat jug stands at the end point of its traversing with one end face below of the turntable. That is the standstill position where the Transfer of the flat can to a subsequent transport system guaranteed is. The flat can is in this standstill position positioned the mouth of the turntable, i.e. the mouth of the Turntable is in relation to the standstill position of the flat can always stopped in the same position. With this defined The position of the mouth of the turntable can be determined which position of the edge of the end wall of the flat can Sliver end will be stored.

Da das Faserband zykloidenförmig abgelegt wird, wird mit Positionierung der Mündung des Drehtellers Einfluß auf die Bildung der letzten Schlinge genommen. Die Drehtellermündung wird positioniert stillgesetzt bezüglich der Längsachse der Flachkanne. Die Positionen sind wählbar. Es ist somit bestimmbar an welcher Position das Schlingenende in die Mündung des Drehtellers (Bandführungskanal) führt.Since the sliver is laid down in a cycloid, positioning is required the mouth of the turntable influences the formation of the last loop taken. The turntable mouth is positioned stopped with respect to the longitudinal axis of the flat can. The Positions can be selected. It is therefore possible to determine at which position the loop end in the mouth of the turntable (belt guide channel) leads.

Die Positionierung eines Faserbandes wird erreicht im Zusammenwirken einer Verzugsvorrichtung und eines Verschiebemittels. Das Verfahren zur Positionierung eines Faserbandendes ist dadurch gekennzeichnet, daß in Stillstandsposition der Flachkanne mittels einer Verzugsvorrichtung eine Verzugsstelle im Faserband zwischen Kalanderwalzenpaar und Bandführungskanal gebildet wird und durch anschließendes Verschieben der Flachkanne mittels Verschiebemittel aus der Stillstandsposition in eine Übergabeposition das Faserband an der Verzugsstelle getrennt und das getrennte Faserbandende aus dem Bandführungskanal gezogen wird, so daß es mit konstanter Länge am Rand der Stirnwandung der Flachkanne positioniert ist. Eine Verzugsstelle wird gebildet, indem die Verzugsvorrichtung im Abstand mindestens einer Stapellänge unterhlab des Kalanderwalzenpaares durch Klemmung des Faserbandes eine Klemmstelle gebildet wird und diese Klemmstelle durch die Verzugsvorrichtung quer zur Förderrichtung des Faserbandes verschoben wird bis ein Verzug eintritt. Es wird zwischen Klemmstelle und Kalanderwalzenpaar eine Verzugsstelle gebildet. Dann wird durch die Verzugseinrichtung die Klemmung des Faserbandes aufgehoben.The positioning of a sliver is achieved in cooperation a drafting device and a displacement means. The A method for positioning a sliver end is characterized in that that in the standstill position of the flat can by a drafting device a drafting point in the sliver between Calender roller pair and belt guide channel is formed and by then moving the flat jug using a moving device the sliver from the standstill position to a transfer position separated at the default point and the separated sliver end is pulled out of the tape guide channel so that it with constant Length positioned at the edge of the end wall of the flat can is. A default point is formed by the default device at a distance of at least one stack length Pair of calender rollers by clamping the sliver one nip is formed and this nip by the drafting device is moved transversely to the conveying direction of the sliver until there is a delay. It is between the nip and the pair of calender rolls formed a default. Then through that Distortion device released the clamping of the sliver.

Die Verzugsstelle könnte auch gebildet werden, wenn die Verzugsvorrichtung in Richtung Bandführungskanal geführt wird. Die Verzugsvorrichtung kann eine ortsbewegliche Klemmvorrichtung oder ein ortsbeweglicher mechanischer Hebel oder Anschlag sein. Das anschließende Verschieben der Flachkanne kann mit einem Verschiebemittel realisiert werden. Ein Verschiebemittel kann sein die Nutzung der Changiervorrichtung und/oder eines zusätzlichen Transportmittels für Flachkannen. Durch die Maschinensteuerung werden die Bewegungsabläufe der Verzugsvorrichtung und des Verschiebemittels gesteuert.The default point could also be formed if the default device is guided in the direction of the tape guide channel. The delay device can a portable clamping device or a portable mechanical lever or stop. The Subsequent moving of the flat can can be done with a moving device will be realized. A means of displacement can be that Use of the traversing device and / or an additional one Means of transport for flat cans. Through the machine control become the movements of the drafting device and the displacement means controlled.

Diese Verfahrensschritte zum Positionieren eines Bandendes haben den Vorteil, daß sie den Gesamtvorgang vereinfachen. Das heißt, auf eine konventionelle, aufwendige Trennvorrichtung für Faserband kann verzichtet werden. Obwohl das Faserband mit der Verzugsstelle aus der Förderrichtung ausgelenkt wird, wird es mit Verschieben des Verschiebemittels vor dem Trennvorgang in die Förderrichtung zurückgeführt. Weiterhin ist das getrennte Bandende, am Kalanderwalzenpaar hängend, im Bandführungskanal positioniert.Have these process steps for positioning a tape end the advantage that they simplify the overall process. This means, to a conventional, expensive sliver separator can be dispensed with. Although the sliver with the default is deflected from the direction of conveyance, it is with Moving the moving means in the before the separation process Direction of conveyance returned. Furthermore, the separate tape end, hanging on the pair of calenders, positioned in the belt guide channel.

Beim Trennen durch Verschieben garantiert die Verzugsstelle stets eine definierte Trennstelle des Bandes. Die Vorrichtung zur Durchführung des Verfahrens hat ein Verschiebemittel für eine Flachkanne und eine Verzugsvorrichtung angeordnet, die mit einer Steuerung verbunden sind. Die Verzugsvorrichtung hat mindestens als Arbeitsmittel einen steuerbaren und beweglichen Klemmarm und Anschlag.The delay point always guarantees when separating by moving a defined separation point of the tape. The device for Carrying out the method has a shifting device for one Flat can and a drafting device arranged with a Control are connected. The delay device has at least as a work tool, a controllable and movable clamping arm and Attack.

Die Positionierung wird mit geringerem Aufwand gegenüber dem Stand der Technik erreicht. Als weiterer Vorteil zeigt sich, daß die Länge des Bandendes beeinflußt werden kann, indem die Stillstandsposition der Flachkanne zusätzlich etwas variiert werden kann.Positioning is compared to that with less effort State of the art achieved. Another advantage is that The length of the tape end can be affected by the stop position the flat can can also be varied somewhat can.

Nachfolgend werden anhand eines Ausführungsbeispieles die Wirkungsweise und erfindungswesentliche Merkmale erläutert.The mode of operation is described below using an exemplary embodiment and features essential to the invention explained.

Figur 1 zeigt schematisch eine Strecke 1 der Textilindustrie sowie eine Flachkanne 14 und deren Verschiebemittel 16 (Changiervorrichtung) sowie den Puffer 15 eines Transportsystems für Flachkannen. In der Strecke 1 wird das Faserband 11 in einem Streckwerk 2 verzogen. Das Streckwerk 2 ist dargestellt durch die Streckwerkswalzenpaare 3, 3'; 4, 4'; 5, 5'. Am Ausgang des Streckwerkes 2 ist ein Meßorgan 17 zur Messung der gelieferten Faserbandlänge. Das Faserband 11 wird an ein Kalanderwalzenpaar 6, 6' geliefert und vom Kalanderwalzenpaar 6, 6' in einen Bandführungskanal 8 eines Drehtellers 7 gefördert. Der Drehteller 7 rotiert, so daß über dessen Mündung 9 das Faserband in einer darunterliegenden Flachkanne 14 abgelegt wird. Die Flachkanne 14 hat eine rechteckförmige Grundfläche. Im leeren Zustand befindet sich ein beweglicher Kannenteller unterhalb bzw. in Höhe des oberen Kannenrandes. Mit zunehmender Befüllung der Kanne wird der Kannenteller entgegen der Kraft einer darunterliegenden Feder nach unten in Richtung Kannenboden bewegt. Die Flachkanne 14 hat schmale Stirnwandungen, die Stirnwandung LSW und die Stirnwandung RSW. Die Flachkanne befindet sich auf einer Changiervorrichtung 160. Die Changiervorrichtung 160 besitzt einen hier nicht dargestellten Antrieb mit Steuervorrichtung. Während des Füllvorganges wird die Flachkanne 14 unterhalb des Drehtellers zwischen den beiden Umkehrpunkten A und B ihres Changierweges AB changiert. Die Flachkanne bewegt sich somit zwischen den beiden dargestellten Positionen der Flachkanne 14 und der Flachkanne 14' (gestrichelt). Durch die Rotation des Drehtellers 7 und die Changierung der Flachkanne wird das Faserband zykloidenförmig auf den Kannenteller der Flachkanne abgelegt. Die Ablage erfolgt von einer Stirnwandug der Flachkanne zur anderen Stirnwandung und umgekehrt. Ein Ablageweg von einer Stirnwandung zur anderen bildet jeweils eine Lage von Faserbandschlingen. Eine gefüllte Flachkanne hat eine Vielzahl solcher Lagen. Die Changiergeschwindigkeit der Flachkanne 14 ist auf die Liefergeschwindigkeit des Drehtellers 7 abgestimmt. Das Anfahren, der Betrieb und das Abbremsen von Drehteller und Flachkanne erfolgen synchron. Wenn das Meßorgan 17 zur Messung der gelieferten Bandlänge den erreichten Grenzwert der gelieferten Faserbandlänge registriert, liefert es zugleich ein Signal an die Maschinensteuerung 13. Die Maschinensteuerung 13 veranlaßt gegenüber den Antrieben für den Drehteller 7 und die Changiervorrichtung 160, daß diese zu einem definierten Zeitpunkt stillgesetzt werden. Diese Stillsetzung erfolgt so, daß die Flachkanne 14 im Stillstand eine Position in Nähe oder im Umkehrpunkt B erreicht, d.h. die Stirnwandung RSW steht in Nähe oder im Umkehrpunkt B und die Stirnwandung LSW steht im Bereich unterhalb des Drehtellers 7. Die Flachkanne 14 befindet sich somit in der Stillstandsposition SP auf dem Changierweg AB. Diese Stillstandsposition SP könnte etwas variiert werden, indem in Nähe des Umkehrpunktes stillgesetzt wird. Dadurch kann Einfluß auf die Länge des zukünftigen Bandendes genommen werden. Figure 1 shows schematically a route 1 of the textile industry as well a flat can 14 and its displacement means 16 (traversing device) and the buffer 15 of a transport system for Flat cans. In section 1, the sliver 11 is in one Drafting device 2 warped. The drafting system 2 is represented by the Drafting roller pairs 3, 3 '; 4, 4 '; 5, 5 '. At the exit of the Drafting unit 2 is a measuring element 17 for measuring the delivered Sliver length. The sliver 11 is on a pair of calender rolls 6, 6 'and from the pair of calender rolls 6, 6' into a belt guide channel 8 promoted a turntable 7. The turntable 7 rotates, so that the sliver in an underlying 9 via its mouth Flat can 14 is stored. The flat can 14 has a rectangular base. Is in the empty state a movable can plate below or at the level of the upper one Can edge. With increasing filling of the jug, the jug plate becomes against the force of an underlying spring moved towards the bottom of the jug. The flat can 14 has narrow end walls, the LSW end wall and the end wall RSW. The flat can is on a traversing device 160. The traversing device 160 has one not shown here Drive with control device. During the filling process the flat can 14 below the turntable between the the two reversal points A and B of their traversing path AB. The flat can thus moves between the two shown Positions of the flat can 14 and the flat can 14 '(dashed). Through the rotation of the turntable 7 and the traversing the flat can, the sliver becomes cycloidal on the can plate the flat can. The filing is done by a End wall of the flat can to the other end wall and vice versa. A storage path forms from one end wall to the other one layer of sliver each. A filled flat jug has a variety of such locations. The traversing speed the flat can 14 is on the delivery speed of the turntable 7 matched. Starting, operation and braking the turntable and the flat jug are synchronized. If the measuring organ 17 to measure the delivered tape length It registers the limit of the delivered sliver length at the same time a signal to the machine control system 13. The machine control system 13 causes opposite the drives for the turntable 7 and the traversing device 160 that this to a defined Time be stopped. This shutdown is such that the flat can 14 at a standstill a position in the vicinity or in the reversal point B reached, i.e. the front wall RSW is nearby or in reversal point B and the front wall LSW is in the area below the turntable 7. The flat can 14 is thus located in the standstill position SP on the traversing path AB. This The standstill position SP could be varied somewhat by being in the vicinity the reversal point is stopped. This can affect the length of the future tape end will be taken.

Figur 2 zeigt schematisch die Zuordnung des Drehtellers 7 aus einer Draufsicht zur Flachkanne. Die Flachkanne 14 befindet sich in der Stillstandsposition SP auf dem Changierweg AB. Der Drehteller 7 befindet sich oberhalb der Flachkanne 14. Die Stellung des Drehtellers 7 zur Stillstandsposition SP der Flachkanne 14 ist positioniert, d.h. der Drehtelle 7 wird beispielsweise stets so stillgesetzt, daß die Mündung 9 des Bandführungskanals 8 stets in der gleichen Position zum Stillstand kommt. Die Position der Mündung 9 wird vorteilhafterweise so eingestellt, daß das Faserband 11 senkrecht in der Längsachse LA der Flachkanne gehalten wird. Das entspricht der Position 90 der Mündung 9. Eine zweite Möglichkeit ergibt sich, wenn der Drehteller um 180° gedreht mit seiner Mündung 9' die Position 90' erreicht. Es sind jedoch auch andere Position der Drehtellermündung 9 denkbar. Es wird mit Position der Drehtellermündung 9 Einfluß auf die Ablage der letzten Schlinge genommen. Es ist somit bestimmbar, an welcher Position das Schlingenende in die Drehtellermündung führt. Die Auswahl anderer Positionen hängt ab von dem später zu erläuternden Arbeitsschritt des Verschiebens.Figure 2 shows schematically the assignment of the turntable 7 from a Top view of the flat can. The flat can 14 is in the standstill position SP on the traversing path AB. The turntable 7 is located above the flat can 14. The position of the Turntable 7 to the standstill position SP of the flat can 14 positioned, i.e. the turntable 7 is always so, for example stopped that the mouth 9 of the tape guide channel 8 always in the same position comes to a standstill. The position of the mouth 9 is advantageously set so that the sliver 11 is held vertically in the longitudinal axis LA of the flat can. This corresponds to position 90 of the mouth 9. A second possibility results when the turntable is rotated by 180 ° with its mouth 9 'reaches position 90'. However, there are also other position of the turntable mouth 9 conceivable. It comes with position the turntable mouth 9 influence the storage of the last Taken noose. It is therefore possible to determine at which position the loop end leads into the turntable mouth. The selection of others Positions depend on the work step to be explained later of moving.

Figur 3 zeigt, daß die Flachkanne 14 in der Stillstandsposition SP stillgesetzt ist. Gleichzeitig ist die Lieferung von Faserband 11 durch das Kalanderwalzenpaar 6, 6' gestoppt. Diesen Stopp veranlaßt die Maschinensteuerung 13. Das Faserband 11 hängt in dem Bandführungskanal 8, durchzieht den Bandführungskanal und liegt in der Flachkanne 14. Jetzt erhält eine Verzugsvorrichtung 12 von der Maschinensteuerung 13 das Signal das Faserband zwischen Kalanderwalzenpaar 6, 6' und der Eintrittsöffnung 10 des Bandführungskanal 8 zu verziehen, d.h. eine Verzugsstelle zu bilden.Figure 3 shows that the flat can 14 in the standstill position SP is stopped. At the same time is the delivery of sliver 11 stopped by the pair of calender rolls 6, 6 '. Caused this stop the machine control 13. The sliver 11 hangs in the Tape guide channel 8, runs through the tape guide channel and lies in the flat can 14. Now a drafting device 12 receives the machine control 13 receives the signal the sliver between the pair of calender rolls 6, 6 'and the inlet opening 10 of the tape guide channel 8 warp, i.e. to form a default.

Figur 3a zeigt, daß jetzt die Flachkanne 14 aus der Stillstandsposition SP verschoben wird mittels Verschiebemittel 16 in Richtung einer Übernahmeposition C. Dabei wird die Vergzugsstelle getrennt und das Faserbandende durch die Kannenbewegung aus dem Bandführungskanal 8 gezogen wird. In Figur 3b hat die Kanne 14 die Übernahmeposition C erreicht. Das Faserbandende E hängt an der Stirnwandung LSW der Flachkanne 14 herab. Da der Drehteller 7 beispielsweise mit seiner Mündung 9 in der Längsachse LA positioniert wurde, kommt das Faserbandende E im mittleren Bereich der Stirnwandung LSW zur Ablage (Fig. 3c).Figure 3a shows that now the flat can 14 from the standstill position SP is shifted in the direction by means of shifting means 16 a takeover position C. The default point is separated and the sliver end from the can movement Tape guide channel 8 is pulled. In FIG. 3b, the can 14 reached takeover position C. The sliver end E is attached the end wall LSW of the flat can 14 down. Since the turntable 7 for example, positioned with its mouth 9 in the longitudinal axis LA the sliver end E comes in the middle of the Front wall LSW for storage (Fig. 3c).

Figur 4 bis 4d zeigen die Bildung einer Verzugsstelle im Faserband mit einer Verzugsvorrichtung. Figur 4 zeigt in einer schematischen Draufsicht die Anfangsposition der Verzugsvorrichtung, d.h. die Arbeitsmittel Klemmarm 20, Anschlag 22 und deren Stellvorrichtungen 21 und 23. Weiterhin ist schematisch dargestellt die Eintrittsöffnung 10 des Bandführungskanals 8 indem sich das Faserband 11 befindet. Neben der Eintrittsöffnung 10 ist ein Anschlag 22 angeordnet. Dieser Anschlag wird mechanisch gehalten und geführt durch eine Stellvorrichtung 23. Diese Stellvorrichtung besitzt einen nicht dargestellten Antrieb und dessen Steuerung sowie einen Verschiebemechanismus. Gegenüberliegend zum Anschlag 22 ist ein Klemmarm 20, ebenfalls außerhalb der Eintrittsöffnung 10 angeordnet. Dieser Klemmarm 20 wird mechanisch gehalten und geführt durch die Stellvorrichtung 21. Diese Stellvorrichtung 21 besitzt ebenso einen nicht dargestellten Antrieb und dessen Steuerung sowie einen Verschiebemechanismus. Der Klemmarm 20 wird durch die Stellvorrichtung 21 beispielsweise quer zur Förderrichtung des Faserbandes 11 bewegt. Der Klemmarm 20 lenkt das Faserband 11 aus und klemmt es mit dem Anschlag 22. Anschlag 22 und Klemmarm 20 bilden eine Klemmstelle KS. Die Klemmstelle KS wird in Fortsetzung der bisherigen Bewegung des Klemmarmes 20 weiter quer verschoben. Dieses Verschieben der Klemmstelle zeigt der Vergleich zwischen Figur 4a und 4b. Die Verschiebung der Klemmstelle KS erfolgt soweit, bis ein Verzug des Faserbandes eintritt. Figur 4c zeigt diese Verzugsstelle. Zur besseren Darstellung erfolgte ein Wechsel zur Seitenansicht. Die Verzugsstelle VS tritt zwischen der Klemmstelle KS und dem Kalanderwalzenpaar 6, 6' auf. In Abhängigkeit des zu verarbeitenden Materials wird dieser Verschiebeweg ermittelt und durch Steuerung der Stellvorrichtungen 21 und 23 eingestellt. Mit erreichtem Verzug und der Bildung einer Verzugsstelle wird die Klemastelle KS geöffnet, d.h. der Klemmarm 20 wird in seine Ausgangsposition zurückgeführt. Als nächster Schritt zur Positionierung eines Bandes erfolgt jetzt das in Figur 3 bis 3c dargestellte Verschieben der Flachkanne 14 zur Übernahmeposition C beispielsweise durch Nutzung der Changiervorrichtung 160. Durch das Verschieben der Flachkanne wird das Faserband mit der Verzugsstelle exakt in Förderrichtung des Bandes, d.h. im Bandführungskanal positioniert und exakt an der Verzugsstelle getrennt. Zugleich wird mit dem Verschieben der Flachkanne das Bandende aus dem Bandführungskanal des Drehtellers gezogen. Das Faserband hängt an definierter Position der Flachkanne. Zugleich ist gewährleistet, daß das Faserbandende stets eine festgelegte Länge besitzt. Von der Übernahmeposition C kann jetzt die Flachkanne 14 von dem Verschiebemittel 16 durch eine nicht dargestellte Übergabevorrichtung verschoben werden auf den Puffer 15 eines Transportsystems. Damit kann eine leere Kanne vom Puffer 15 auf das Verschiebemittel 16 gewechselt werden. Somit ist ein Kannenwechsel vollzogen.Figures 4 to 4d show the formation of a draft in the sliver with a drafting device. Figure 4 shows a schematic Top view of the initial position of the drafting device, i.e. the work clamp arm 20, stop 22 and their actuators 21 and 23. Furthermore, it is shown schematically the inlet opening 10 of the tape guide channel 8 by the Sliver 11 is located. There is a stop next to the inlet opening 10 22 arranged. This stop is held mechanically and guided by an actuator 23. This actuator has a drive, not shown, and its control as well as a sliding mechanism. Opposite the stop 22 is a clamp arm 20, also outside the entry opening 10 arranged. This clamping arm 20 is held mechanically and guided by the actuator 21. This actuator 21 also has a drive and not shown its control and a sliding mechanism. The clamp arm 20 is, for example, transverse to the adjusting device 21 Conveying direction of the sliver 11 moves. The clamping arm 20 steers the sliver 11 and clamps it with the stop 22nd stop 22 and clamping arm 20 form a clamping point KS. The KS clamping point will continue the previous movement of the clamping arm 20th moved further across. This shifting of the clamping point shows the comparison between Figure 4a and 4b. The shift of the Clamping point KS takes place until the sliver warps entry. Figure 4c shows this default. For better illustration there was a change to the side view. The default VS occurs between the nip KS and the pair of calender rolls 6, 6 '. Depending on the material to be processed this displacement path is determined and by controlling the Actuators 21 and 23 set. With delay reached and the creation of a default point, the KS terminal point is opened, i.e. the clamping arm 20 is returned to its starting position. The next step in positioning a belt now takes place shown in Figure 3 to 3c shifting Flat can 14 to takeover position C, for example, by use the traversing device 160. By moving the Flat can, the sliver with the draft point is exactly in Conveying direction of the belt, i.e. positioned in the tape guide channel and exactly separated at the default point. At the same time with the Move the flat can of the tape end out of the tape guide channel of the turntable. The sliver hangs at a defined position the flat can. At the same time it is ensured that the sliver end always has a fixed length. From the takeover position C can now the flat can 14 from the displacement means 16 moved by a transfer device, not shown are on the buffer 15 of a transport system. With that a empty can from the buffer 15 changed to the displacement means 16 will. A can change is now complete.
