Abstract

In a process to splice the two ends of a web of corrugated paper following a break, an electronic monitoring assembly (36) detects a drop in web tension with respect to target value. In the event of the tension exceeding a maximum permissible target value, the electronic assembly activates a combined web cutter and splicing station (19). The electronic assembly further sets the target value. In the splice process, a length of web feed is paid out and brought to overlap with the tail end of the previous web. The ends are cut, spliced, and the web tension measured. Also claimed is a corrugated paper splice assembly in which a change in the operating condition de-activates the assembly by stopping the motor drive (32).

Description

Die Erfindung betrifft eine Splice-Vorrichtung und ein Verfahren zum Splicen von Material-Bahnen, insbesondere von Papier-Bahnen zur Herstellung von einer Wellpappe-Bahn in einer Wellpappe-Anlage.The invention relates to a splicing device and a method for splicing material webs, in particular paper webs for producing a corrugated web in a corrugated board plant.

Bekannte Splice-Vorrichtungen verbinden eine zu Ende gehende erste Material-Bahn mit einer neuen zweiten Material-Bahn. An einer Verbindungsstelle im Bereich des Bahnendes der ersten Material-Bahn wird diese mit dem Bahnanfang der zweiten Material-Bahn verklebt, wobei der vor der Verbindungsstelle verbleibende Teil der ersten Material-Bahn beim Verbinden abgetrennt wird. Dieser Vorgang wird in der Fachsprache als Splicen und eine entsprechende Vorrichtung als Splice-Vorrichtung bezeichnet.Known splicing devices connect a terminating first material web to a new second material web. At a connection point in the region of the web end of the first material web, it is glued to the web start of the second material web, wherein the part of the first material web remaining in front of the connection point is severed during bonding. This process is referred to in the jargon as Splicen and a corresponding device as Splice device.

Auch bei einem ungewollten Abriss einer Material-Bahn beim Abrollen von einer Material-Rolle muss ein Splicen der Material-Bahnen erfolgen. Zum Detektieren eines Abrisses einer Material-Bahn weisen bekannte Splice-Vorrichtungen Lichtschranken auf, die bei einem Abriss das Splicen der Material-Bahnen einleiten. Nachteilig bei derartigen Splice-Vorrichtungen ist der apparative Aufwand, der zum Detektieren eines Abrisses einer Material-Bahn erforderlich ist.Even with an unwanted demolition of a material web when unrolling from a roll of material splicing of the material webs must be done. For detecting a tear of a material web, known splice devices have light barriers which initiate the splicing of the material webs in the event of a demolition. A disadvantage of such splicing devices is the equipment required to detect a tear of a material web.

Derartige Splice-Vorrichtungen und Verfahren werden z.B. in DE 27 49 935 A1 und DE 26 27 103 A1 offenbart.Such splice devices and methods are described, for example in DE 27 49 935 A1 and DE 26 27 103 A1 disclosed.

Der Erfindung liegt die Aufgabe zugrunde, eine Splice-Vorrichtung und ein Verfahren zum Splicen von Material-Bahnen zu schaffen, die ein einfaches Detektieren eines Abrisses einer Material-Bahn und ein einfaches Einleiten des Splicens der Material-Bahnen ermöglichen.The invention has for its object to provide a splicing device and a method for splicing material webs, which allow easy detection of a tear of a material web and easy initiation of the splicing of the material webs.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche 1 und 8 gelöst. Der Kern der Erfindung besteht darin, dass mittels der mindestens einen Mess-Einrichtung zumindest eine zu der Bahnspannung der endlosen Material-Bahn korrespondierende Messgröße messbar ist, wobei diese Messgröße zum Detektieren einer Abweichung der Bahnspannung von einem Bahnspannungs-Sollwert der mindestens einen elektronischen Steuer-Einrichtung zugeführt wird. Überschreitet die detektierte Abweichung betragsmäßig eine maximal zulässige Abweichung, so erkennt die elektronische Steuer-Einrichtung einen Abriss der abrollenden Material-Bahn und führt mindestens eine Betriebszustands-Änderung mindestens einer Bearbeitungs-Einrichtung der Material-Bahnen herbei. Die mindestens eine Steuer-Einrichtung leitet somit mittels der zu der Bahnspannung korrespondierenden Messgröße die mindestens eine Betriebszustands-Änderung ein, wobei die mindestens eine Mess-Einrichtung ohnehin zum Einstellen der Bahnspannung der endlosen Material-Bahn in der Splice-Vorrichtung vorhanden ist und somit keine weiteren Mess-Einrichtungen zum Detektieren von einem Abriss, wie beispielsweise Lichtschranken, erforderlich sind.This object is solved by the features of independent claims 1 and 8. The essence of the invention is that by means of at least a measurement device is at least one measurable to the web tension of the endless material web measurement variable is measurable, this measure is supplied to detect a deviation of the web tension of a web tension setpoint of the at least one electronic control device. If the detected deviation exceeds a maximum permissible deviation in terms of amount, then the electronic control device detects a demolition of the rolling material web and brings about at least one operating state change of at least one processing device of the material webs. The at least one control device thus initiates the at least one operating state change by means of the measured variable corresponding to the web tension, wherein the at least one measuring device is present anyway for setting the web tension of the endless material web in the splicing device and thus none further measuring means for detecting a demolition, such as photoelectric sensors, are required.

In this state, the first material web 9 is passed through only the processing rollers 22, whereas the second material web 11 is held by the processing rollers 22 in a waiting position, so that if necessary with the first material web. 9 to the endless material web 21 is connectable.

Der Schneide- und Verbinde-Einrichtung 19 ist eine erste Umlenk-Walze 24 nachgeordnet, die im Bereich der zweiten Material-Rolle 12 drehbar an dem Grundgestell-Träger 5 gelagert ist, wobei die Material-Bahn 21 zur Umlenkung um diese geführt ist. Der ersten Umlenk-Walze 24 ist eine zweite Umlenk-Walze 25 nachgeordnet, die drehbar an einem Schlitten 26 gelagert ist. Der Schlitten 26 ist im Bereich eines dem Grundgestell-Ständer 4 gegenüberliegenden Endes des Grundgestell-Trägers 5 angeordnet, wobei der Schlitten 26 entlang einer parallel zu dem Boden 6 verlaufenden Verlagerungs-Richtung 27 in einer Schlitten-Führung 28 verlagerbar ist. Die Schlitten-Führung 28 erstreckt sich im Wesentlichen entlang des gesamten Grundgestell-Trägers 5, wobei der Schlitten 26 zwischen einer ersten End-Position und einer zweiten End-Position verlagerbar ist. In der ersten End-Position ist der Schlitten 26 einem Auslauf 29 der Material-Bahn 21 zugewandt, wohingegen der Schlitten 26 in der zweiten End-Position dem Auslauf 29 abgewandt ist. Die Figur zeigt den Schlitten 26 in der zweiten End-Position. Zur Umlenkung der Material-Bahn 21 im Bereich des Auslaufs 29 ist eine dritte Umlenk-Walze 30 drehbar an dem Grundgestell-Träger 5 angeordnet. Der dritten Umlenk-Walze 30 ist eine vierte Umlenk-Walze 31 nachgeordnet, die zwischen der zweiten und dritten Umlenk-Walze 25, 30 am Schlitten 26 drehbar gelagert ist.The cutting and connecting device 19 is arranged downstream of a first deflection roller 24, which is rotatably mounted in the region of the second material roll 12 on the base frame carrier 5, wherein the material web 21 is guided for deflection about this. The first deflecting roller 24 is followed by a second deflecting roller 25 which rotatably on a carriage 26th is stored. The carriage 26 is arranged in the region of the base frame stand 4 opposite end of the base support 5, wherein the carriage 26 along a direction parallel to the bottom 6 extending displacement direction 27 in a carriage guide 28 is displaceable. The carriage guide 28 extends substantially along the entire base support 5, wherein the carriage 26 is displaceable between a first end position and a second end position. In the first end position of the carriage 26 faces an outlet 29 of the material web 21, whereas the carriage 26 is remote in the second end position of the outlet 29. The figure shows the carriage 26 in the second end position. For deflecting the material web 21 in the region of the outlet 29, a third deflection roller 30 is rotatably arranged on the base frame carrier 5. The third deflection roller 30 is a fourth deflection roller 31 downstream, which is rotatably mounted on the carriage 26 between the second and third deflection roller 25, 30.

Zum Verlagern des Schlittens 26 entlang der Schlitten-Führung 28 sind an dem Schlitten 26 nicht dargestellte Rollen drehbar gelagert. Das Verlagern des Schlittens 26 erfolgt mittels einer elektrischen Antriebs-Einrichtung 32. Die Antriebs-Einrichtung 32 weist zum Antreiben des Schlittens 26 einen Servo-Motor 33 auf, der über eine Leitung 34 mit einer Leistungselektronik 35 in Verbindung steht. Der Servo-Motor 33 kann als AC-Servo-Motor oder als DC-Servo-Motor ausgebildet sein, wobei die Leistungselektronik 35 entsprechend angepasst sein muss. Der Servo-Motor 33 ist an dem Grundgestell-Träger 5 befestigt und in drehmomentübertragender Weise mit einer der Rollen verbunden.For displacing the carriage 26 along the carriage guide 28, rollers (not shown) are rotatably mounted on the carriage 26. The displacement of the carriage 26 is effected by means of an electric drive device 32. The drive device 32 has for driving the carriage 26 to a servo motor 33 which is connected via a line 34 with a power electronics 35 in combination. The servo motor 33 may be formed as an AC servo motor or as a DC servo motor, the power electronics 35 must be adjusted accordingly. The servo motor 33 is fixed to the base frame 5 and connected to one of the rollers in a torque-transmitting manner.

Die Antriebs-Einrichtung 32 steht in Signalverbindung mit einer elektronischen Steuer-Einrichtung 36, die zur Ansteuerung der Antriebs-Einrichtung 32 einen Servo-Regler 37 aufweist. Der Servo-Regler 37 dient zur Einregelung einer gewünschten Regelgröße des Servo-Motors 33.The drive device 32 is in signal communication with an electronic control device 36, which is used to drive the drive device 32 has a servo-controller 37. The servo-controller 37 serves to control a desired controlled variable of the servo-motor 33.

Die Steuer-Einrichtung 36 steht über eine Signalleitung 38 mit einer Mess-Einrichtung 39 in Signalverbindung, wobei die Mess-Einrichtung 39 zum Messen einer Messgröße dient, die zu einer Bahnspannung der endlosen Material-Bahn 21 korrespondiert. Die Mess-Einrichtung 39 ist unmittelbar an der Antriebs-Einrichtung 32 angeordnet und derart ausgebildet, dass als Messgröße eine den Zustand der mindestens einen Antriebs-Einrichtung 32 charakterisierende Größe messbar ist. Die Messgröße stellt somit eine den Zustand der Antriebs-Einrichtung 32 charakterisierende Größe dar, die gleichzeitig eine Bestimmung der Bahnspannung oder einer der Bahnspannung entsprechenden Größe ermöglicht. In der Figur ist die Mess-Einrichtung 39 eine Strom-Mess-Einrichtung, mittels der als Messgröße ein Strom der Antriebs-Einrichtung 32 messbar ist. Der von der Antriebs-Einrichtung 32 aufgenommene Strom entspricht dem aufgebrachten Drehmoment des Servo-Motors 33, das zum Halten des Schlittens 26 in der zweiten End-Position mit einer gewünschten Bahnspannung der Material-Bahn 21 erforderlich ist.The control device 36 is in signal connection via a signal line 38 to a measuring device 39, the measuring device 39 serving to measure a measured variable which corresponds to a web tension of the endless material web 21. The measuring device 39 is arranged directly on the drive device 32 and designed such that a variable characterizing the state of the at least one drive device 32 can be measured as a measured variable. The measured variable thus represents a state characterizing the state of the drive device 32, which at the same time allows a determination of the web tension or of a size corresponding to the web tension. In the figure, the measuring device 39 is a current-measuring device, by means of which a current of the drive device 32 can be measured as a measured variable. The current received by the drive device 32 corresponds to the applied torque of the servo motor 33 required to hold the carriage 26 in the second end position with a desired web tension of the material web 21.

Alternativ kann die Mess-Einrichtung 39 als Spannungs-Mess-Einrichtung ausgebildet sein, mittels der als Messgröße eine Spannung der Antriebs-Einrichtung 32 messbar ist. Die Spannung entspricht einer Drehzahl des Servo-Motors 33. Weiterhin kann die Mess-Einrichtung 39 als Drehzahl-Mess-Einrichtung ausgebildet sein, mittels der als Messgröße eine Drehzahl der Antriebs-Einrichtung 32 messbar ist. Beispielsweise sind als Drehzahl-Mess-Einrichtungen bekannte Resolver oder Inkrementalgeber einsetzbar. Alternativ zu den beschriebenen Mess-Einrichtungen 39 können auch mechanische Mess-Einrichtungen, wie beispielsweise Mess-Dosen an einer der Umlenk-Walzen oder eine Tänzer-Walze verwendet werden.Alternatively, the measuring device 39 may be designed as a voltage measuring device by means of which a voltage of the drive device 32 can be measured as the measured variable. The voltage corresponds to a speed of the servo motor 33. Furthermore, the measuring device 39 may be formed as a speed-measuring device, by means of which a speed of the drive device 32 can be measured as a measured variable. For example, resolvers or incremental encoders known as speed measuring devices can be used. As an alternative to the described measuring devices 39 can also mechanical measuring devices, such as measuring cans on one of the deflection rollers or a dancer roller can be used.

In der Figur ist ein durchgehender Riss 40 in der ersten Material-Bahn 9 zwischen der ersten Material-Rolle 10 und der Umlenk-Walze 18 dargestellt, der zu einem Abriss der Material-Bahn 9 führt. Zur Detektion des Abrisses ist die Steuer-Einrichtung 36 derart ausgebildet, dass mittels der zu der Bahnspannung korrespondierenden Messgröße eine Abweichung der Bahnspannung von einem Bahnspannungs-Sollwert detektierbar ist und bei einer betragsmäßigen Überschreitung einer maximal zulässigen Abweichung durch die detektierte Abweichung die Schneide- und Verbinde-Einrichtung 19 ansteuerbar ist.In the figure, a continuous crack 40 in the first material web 9 between the first material roll 10 and the deflection roller 18 is shown, which leads to a demolition of the material web 9. In order to detect the break, the control device 36 is designed such that a deviation of the web tension from a web tension set point can be detected by means of the measured variable corresponding to the web tension and the cutting and joining at a magnitude exceeding a maximum allowable deviation by the detected deviation Device 19 is controllable.

Nachfolgend wird die Funktionsweise der Splice-Vorrichtung 1 beschrieben. Die erste Material-Bahn 9 wird von der ersten Material-Rolle 10 abgerollt und über die Zuführ-Walze 18 durch die Schneide- und Verbinde-Einrichtung 19 geführt. Die Bahnspannung der endlosen Material-Bahn 21 wird mittels Abroll-Bremsen der ersten Abroll-Einrichtung 7 eingestellt, wobei die Abroll-Bremsen von der Steuer-Einrichtung 36 gesteuert werden. Nach der Schneide- und Verbinde-Einrichtung 19 wird die als endlose Material-Bahn 21 bezeichnete erste Material-Bahn 9 mittels der ersten Umlenk-Walze 24 um 180° umgelenkt und zu der zweiten Umlenk-Walze 25 geführt, wo die endlose Material-Bahn 21 erneut um 180° umgelenkt wird. Anschließend wird die Material-Bahn 21 zu der dritten Umlenk-Walze 30 geführt, wo diese erneut umgelenkt und zur vierten Umlenk-Walze 31 zurückgeführt wird. Nach einem nochmaligen Umlenken wird die endlose Material-Bahn 21 zum Auslauf 29 geführt, wo diese die Splice-Vorrichtung 1 zur Herstellung von Wellpappe verlässt. Der Schlitten 26 befindet sich in der zweiten End-Position, so dass die Material-Bahn 21 zwischen den Umlenk-Walzen 24, 25, 30, 31 Schleifen ausbildet. Der Schlitten 26 wird gegen die Bahnspannung der Material-Bahn 21 mittels der Antriebs-Einrichtung 32 in der zweiten End-Position gehalten. Die zweite Material-Bahn 11 ist teilweise von der zweiten Material-Rolle 12 abgerollt und befindet sich in der Schneide- und Verbinde-Einrichtung 19 in einer Warteposition.The operation of the splicing device 1 will be described below. The first material web 9 is unrolled from the first material roll 10 and fed through the feed roller 18 through the cutting and joining device 19. The web tension of the endless web of material 21 is adjusted by means of roll-down braking of the first unrolling device 7, wherein the unwinding brakes are controlled by the control device 36. After the cutting and joining device 19, the designated as endless material web 21 first material web 9 is deflected by the first deflection roller 24 by 180 ° and guided to the second deflection roller 25, where the endless material web 21 is again deflected by 180 °. Subsequently, the material web 21 is guided to the third deflection roller 30, where it is deflected again and returned to the fourth deflection roller 31. After a further deflection, the endless material web 21 is led to the outlet 29, where it leaves the splicing device 1 for the production of corrugated board. The carriage 26 is in the second end position, so that the material web 21st between the deflection rollers 24, 25, 30, 31 forms loops. The carriage 26 is held against the web tension of the material web 21 by means of the drive means 32 in the second end position. The second web of material 11 is partially unwound from the second roll of material 12 and is in a waiting position in the cutting and joining device 19.

Aufgrund des stetigen Abrollens der ersten Material-Bahn 9 geht die erste Material-Rolle 10 nach einer bestimmten Zeit zu Ende, so dass die zweite Material-Bahn 11 mit der ersten Material-Bahn 9 verbunden werden muss. Aufgrund der bekannten Länge der ersten Material-Bahn 9 erkennt die Steuer-Einrichtung 36, wann die erste Material-Rolle 10 zu Ende geht. Bevor dies eintritt, steuert die Steuer-Einrichtung 36 die Schneide- und Verbinde-Einrichtung 19 sowie die Antriebs-Einrichtung 32 an. Die erste Material-Bahn 9 wird zum Stillstand gebracht, wobei durch das Verlagern des Schlittens 26 von der zweiten End-Position in die erste End-Position die von der Material-Bahn 21 gebildeten Schleifen aufgelöst werden und die Material-Bahn 21 weiterhin die Splice-Vorrichtung 1 verlässt. Dadurch, dass die erste Material-Bahn 9 in der Schneide- und Verbinde-Einrichtung 19 ruht, ist ein Verbinden von dieser mit der zweiten Material-Bahn 11 möglich. Die zweite Material-Bahn 11 wird mittels der Bearbeitungs-Walzen 22 mit der ersten Material-Bahn 9 an einer Verklebestelle verklebt, wobei die erste Material-Bahn 9 von der Material-Bahn 21 mittels der Schneid-Messer 23 abgetrennt wird. Die zweite Material-Bahn 11 wird nun von der zweiten Material-Rolle 12 abgerollt, wobei während des Abrollens der Schlitten 26 zur Bildung von Schleifen der Material-Bahn 21 mittels der Antriebs-Einrichtung 32 von der ersten End-Position in die zweite End-Position verlagert wird. Während des Abrollens der zweiten Material-Rolle 12 wird weiterhin eine neue Material-Rolle in der ersten Abroll-Einrichtung 7 angeordnet.Due to the continuous rolling of the first material web 9, the first material roll 10 ends after a certain time, so that the second material web 11 has to be connected to the first material web 9. Due to the known length of the first material web 9, the control device 36 recognizes when the first material roll 10 comes to an end. Before this occurs, the control device 36 controls the cutting and connecting device 19 and the drive device 32. The first web of material 9 is brought to a standstill, whereby by displacing the carriage 26 from the second end position to the first end position, the loops formed by the material web 21 are dissolved and the web of material 21 continues to break the splice Device 1 leaves. As a result of the fact that the first material web 9 rests in the cutting and joining device 19, it is possible to connect it to the second material web 11. The second material web 11 is bonded by means of the processing rollers 22 to the first material web 9 at a bonding site, wherein the first material web 9 is separated from the material web 21 by means of the cutting blade 23. The second material web 11 is now unrolled from the second material roll 12, wherein during the unwinding of the carriage 26 for forming loops of the material web 21 by means of the drive means 32 from the first end position to the second end Position is shifted. While unrolling the second roll of material 12, a new material roll is further arranged in the first unrolling device 7.

Im Unterschied zu dem oben beschriebenen Splicen der Material-Bahnen 9, 11 ist bei einem zufälligen Abriss der ersten Material-Bahn 9 nicht bekannt, wann diese endet. Zum Erkennen eines Abrisses wird mittels der Mess-Einrichtung 39 ständig eine zu der Bahnspannung korrespondierende Messgröße gemessen. Als Messgröße wird im vorliegenden Ausführungsbeispiel ein Strom der Antriebs-Einrichtung 32 gemessen, der dem Drehmoment des Servo-Motors 33 entspricht, das zum Halten des Schlittens 26 gegen die in Verlagerungs-Richtung 27 wirkende Bahnspannung erforderlich ist. Durch einen Riss 40 in der ersten Material-Bahn 9 nimmt die Bahnspannung der Material-Bahn 21 ab, wodurch das von dem Servo-Motor 33 aufzubringende Drehmoment ebenfalls abnimmt. Die Mess-Einrichtung 39 misst eine dem Drehmoment entsprechende Abnahme des Stroms. Die Steuer-Einrichtung 36 stellt die Abnahme des Stroms anhand von Messwerten fest und detektiert eine Abweichung der Bahnspannung von einem Bahnspannungs-Sollwert. Dabei kann in der Steuer-Einrichtung 36 entweder die Bahnspannung berechnet oder eine der Bahnspannung entsprechende Größe berechnet werden. Überschreitet die detektierte Abweichung betragsmäßig eine maximal zulässige Abweichung, so erkennt die Steuer-Einrichtung 36 einen Abriss der ersten Material-Bahn 9 und führt eine Betriebszustands-Änderung einer den Abroll-Einrichtungen 7, 8 nachgeordneten Bearbeitungs-Einrichtung herbei. Beispielsweise steuert die Steuer-Einrichtung 36 die Schneide- und Verbinde-Einrichtung 19 sowie die Antriebs-Einrichtung 32 in bereits beschriebener Weise an. Zum Auf rechterhalten der endlosen Material-Bahn 21 wird die zweite Material-Bahn 11 dann in der bereits beschriebenen Weise mit der ersten Material-Bahn 9 verbunden. Alternativ oder zusätzlich kann die Steuer-Einrichtung 36 eine Betriebszustands-Änderung derart herbeiführen, dass eine der Splice-Vorrichtung 1 nachgeordnete Bearbeitungs-Einrichtung zur Herstellung von Wellpappe deaktiviert wird.In contrast to the splicing of the material webs 9, 11 described above, it is not known in a random demolition of the first material web 9 when it ends. In order to detect a break, a measured variable corresponding to the web tension is constantly measured by means of the measuring device 39. As a measured variable in the present embodiment, a current of the drive device 32 is measured, which corresponds to the torque of the servo motor 33, which is required for holding the carriage 26 against the force acting in the displacement direction 27 web tension. By a crack 40 in the first material web 9, the web tension of the material web 21 decreases, whereby the torque to be applied by the servo motor 33 also decreases. The measuring device 39 measures a decrease in the current corresponding to the torque. The control device determines the decrease of the current on the basis of measured values and detects a deviation of the web tension from a web tension set value. In this case, either the web tension can be calculated in the control device 36 or a variable corresponding to the web tension can be calculated. If the detected deviation exceeds a maximum permissible deviation in terms of amount, then the control device 36 detects an outline of the first material web 9 and introduces an operating state change of a processing device arranged downstream of the rolling devices 7, 8. For example, the control device 36 controls the cutting and connecting device 19 and the drive device 32 in the manner already described. To maintain on the endless material web 21, the second material web 11 is then connected in the manner already described with the first material web 9. Alternatively or additionally, the control device 36 cause an operating state change such that one of the splicing device 1 downstream processing means for producing corrugated cardboard is deactivated.

Wird als Mess-Einrichtung 39 eine Spannungs-Mess-Einrichtung oder eine Drehzahl-Mess-Einrichtung verwendet, so detektiert die Steuer-Einrichtung 36 aufgrund der stark absinkenden Bahnspannung nach einem Abriss der ersten Material-Bahn 9 eine kurzzeitige Bewegung des Schlittens 26 und des Servo-Motors 33. Eine derartige Bewegung kann unmittelbar mittels der Drehzahl-Mess-Einrichtung oder anhand der mittels der Spannungs-Mess-Einrichtung gemessenen Spannung detektiert werden.If a voltage measuring device or a rotational speed measuring device is used as the measuring device 39, then the control device 36 detects a brief movement of the carriage 26 and of the slide 9 due to the strongly decreasing web tension after a demolition of the first material web 9 Servo motor 33. Such a movement can be detected directly by means of the speed measuring device or by means of the voltage measured by the voltage measuring device.

Dadurch, dass zur Detektion eines Risses 40 und in Folge dessen einer Abweichung der Bahnspannung von einem Bahnspannungs-Sollwert eine Mess-Einrichtung 39 verwendet wird, die ohnehin zum Messen der Bahnspannung mittels der an dem Schlitten 26 angeordneten zweiten Umlenk-Walze 25 und zum Halten des Schlittens 26 vorhanden ist, sind keine zusätzlichen Mess-Einrichtungen erforderlich. Durch eine entsprechende Ausgestaltung der Steuer-Einrichtung 36 wird eine mittels der Mess-Einrichtung 39 gemessenen Messgröße derart verarbeitet, dass mittels dieser ein Abriss der Material-Bahnen 9, 11 einfach erkennbar und ein Splicen der Material-Bahnen 9, 11 einfach einleitbar ist.Characterized in that a measuring device 39 is used for detecting a crack 40 and consequently a deviation of the web tension from a web tension setpoint, anyway for measuring the web tension by means of the second deflecting roller 25 arranged on the carriage 26 and for holding of the carriage 26, no additional measuring equipment is required. By means of a corresponding configuration of the control device 36, a measured variable measured by means of the measuring device 39 is processed in such a way that it easily reveals the material webs 9, 11 and a splicing of the material webs 9, 11 can be easily initiated.
