Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Strangmaschine, insbesondere Filterstrangmaschine, der Tabak verarbeitenden Industrie, mit einer Umlenkrolle zur Zufuhr einer Papierbahn zu einer Formatvorrichtung, wobei die Papierbahn stromabwärts zu der Umlenkrolle in der Formatvorrichtung um einen Strang, insbesondere Filterstrang, gewickelt wird.The invention relates to a method for operating a stranding machine, in particular filter rod machine, the tobacco-processing industry, with a deflection roller for feeding a paper web to a format device, wherein the paper web is wound downstream of the deflection roller in the format device by a strand, in particular filter strand.

Die Erfindung betrifft ferner eine Papierbahnzuführungsvorrichtung mit einer Umlenkrolle zur Führung einer Papierbahn zu einer Formatvorrichtung, in der die Papierbahn um einen Filterstrang oder einen Tabakstrang wickelbar ist, wobei die Umlenkrolle angetrieben ist.The invention further relates to a paper web feed device with a deflection roller for guiding a paper web to a formatting device in which the paper web is wound around a filter strand or a tobacco rod, wherein the deflection roller is driven.

Aus JP 02 008138 A ist eine Vorrichtung zum Säubern eines Papierförderers in einem Drucker bzw. Kopierer bekannt, wobei ein Fell relativ zur Tonerwalze gerieben wird, wodurch die Walze selbst gereinigt wird. Die Reinigung geschieht dadurch, dass ein Fell, das mit Lösungsmittel imprägniert ist, relativ zur Tonerwalze gerieben wird, wodurch die Walze selbst gereinigt wird.Out JP 02 008138 A a device for cleaning a paper conveyor in a printer or copier is known, wherein a Fur is rubbed relative to the toner roller, whereby the roller is cleaned itself. The cleaning is done by rubbing a skin impregnated with solvent relative to the toner roller, thereby cleaning the roller itself.

EP 0 499 720 A1 offenbart ein Handling-System für beschichtete Fotopapierbahnen, auf die flüssige Zusammensetzungen aufgebracht sind. In Abhängigkeit eines bestimmten Weges, den die Bahnen zurücklegen, ist es notwendig, dass bei einem Kontakt mit Rollen eine vollständige Austrocknung der Beschichtungen stattgefunden hat. Sofern dieses nicht der Fall ist, findet eine Kontamination der Rollen statt. Insbesondere wird das Handling-System bei fotografischem Material verwendet. Es wird durch das Handling-System verhindert, dass das Fördersystem der Bahnen durch ungenügend getrocknete Teilen der Bahnen kontaminiert wird. Hierzu wird zunächst überprüft, ob ein Teil einer nicht einheitlich beschichteten Bahn vorliegt, die zu einem nicht vollständig getrockneten Teil der Beschichtung führt. Sofern dieses der Fall ist, wird dieser Teil der Bahn mit einer Bürste abgebürstet. EP 0 499 720 A1 discloses a handling system for coated photographic paper webs to which liquid compositions are applied. Depending on a particular path traversed by the webs, it is necessary that complete co-drying of the coatings has occurred upon contact with rollers. If this is not the case, a contamination of the roles takes place. In particular, the handling system is used in photographic material. It is prevented by the handling system that the conveyor system of the webs is contaminated by insufficiently dried parts of the webs. For this purpose, it is first checked whether a part of a non-uniformly coated web is present, which leads to a not completely dried part of the coating. If this is the case, this part of the track is brushed off with a brush.

Aus der DE 36 00 321 C2 ist eine Papierbahnzuführungsvorrichtung für eine Maschine zur Zigarettenherstellung bekannt. Es ist eine Saugtrommel zum Fördern wenigstens einer Papierbahn auf einem Weg zu einer Formatvorrichtung offenbart, wobei zur Führung der Papierbahn die Saugtrommel mit Saugluft versetzt wird, so dass die Saugluft durch Öffnungen der Saugtrommel auf die Papierbahn einwirken kann. Es sind hierzu entsprechende Steuerkörper in der Saugtrommel vorgesehen, die dafür sorgen, dass nur in dem Bereich, in dem die Papierbahn an der Saugtrommel anliegt, auch eine entsprechende Saugwirkung auf die Papierbahn vorhanden ist.From the DE 36 00 321 C2 For example, a paper web feeding apparatus for a cigarette making machine is known. It is a suction drum for conveying at least one paper web on one Path to a formatting device disclosed, wherein for guiding the paper web, the suction drum is mixed with suction air, so that the suction air can act through openings of the suction drum on the paper web. For this purpose, corresponding control bodies are provided in the suction drum, which ensure that only in the area in which the paper web rests against the suction drum, a corresponding suction effect on the paper web is present.

Die Zuführung einer Papierbahn zur Formatvorrichtung ist im Hinblick auf die Lage der Papierbahn sehr wichtig, da schon eine geringe Lageänderung dazu führen kann, dass die Papierbahn nicht mehr korrekt um den Strang aus einem Material der Tabak verarbeitenden Industrie, beispielsweise einem Zigarettenstrang oder einem Filterstrang, gewickelt und geschlossen werden kann.The feeding of a paper web to the format device is very important in view of the position of the paper web, since even a small change in position may mean that the paper web is no longer correct around the strand of a material of the tobacco-processing industry, for example a cigarette rod or a filter strand, can be wrapped and closed.

Um somit eine entsprechend gleichmäßige Lage der Papierbahn, die in die Formatvorrichtung eingebracht wird, vorzusehen, wird beispielsweise eine Lagenregelung vorgenommen.In order to thus provide a correspondingly uniform position of the paper web which is introduced into the format device, a layer control is carried out, for example.

Diese ist insbesondere bei sehr schnellen Strangmaschinen zeitkritisch, so dass eine sehr effiziente und damit kostenintensive Lagereglung notwendig ist.This is time-critical especially in the case of very fast stranding machines, so that a very efficient and thus cost-intensive position control is necessary.

Es ist Aufgabe der vorliegenden Erfindung, einen sicheren Einlauf einer Papierbahn in eine Formatvorrichtung vorzusehen, bei der insbesondere die Lage der Papierbahn möglichst gleich bleibend sein soll bzw. ruhig gehalten werden soll.It is an object of the present invention to provide a secure inlet of a paper web in a format device, in which in particular the position of the paper web should be as constant as possible or should be kept quiet.

Gelöst wird diese Aufgabe durch ein Verfahren zum Betreiben einer Strangmaschine, insbesondere Filterstrangmaschine, der Tabak verarbeitenden Industrie, mit einer Umlenkrolle zur Zufuhr einer Umhüllungsmaterialbahn zu einer Formatvorrichtung, wobei die Umhüllungsmaterialbahn, insbesondere Papierbahn, stromabwärts zu der Umlenkrolle in der Formatvorrichtung um einen Strang, insbesondere Filterstrang, gewickelt wird, wobei die Umlenkrolle im Betrieb der Strangmaschine gesäubert wird.This object is achieved by a method for operating a stranding machine, in particular filter rod machine, the tobacco-processing industry, with a deflection roller for supplying a wrapping material web to a format device, wherein the Wrapping material web, in particular paper web, downstream of the deflection roller in the formatting device is wound around a strand, in particular a filter strand, wherein the deflection roller is cleaned during operation of the stranding machine.

Es ist nämlich erfindungsgemäß erkannt worden, dass es überraschenderweise ausreichend ist, die Umlenkrolle, nämlich insbesondere die Umlenkrolle, die zur Formatvorrichtung vorzugsweise am nächsten ist, sauber zu halten, so dass die Umhüllungsmaterialbahnlage sich durch eine fortwährend saubere Umlenkrolle nicht verändert. Eine Lageregelung der Umlenkrolle ist dann nicht notwendig, so dass das erfindungsgemäße Verfahren ohne Lageregelung wenigstens im Hinblick auf die Neigung der Umlenkrolle auskommt.It has in fact been recognized according to the invention that it is surprisingly sufficient to keep the deflection roller, namely in particular the deflection roller, which is preferably closest to the format device, clean, so that the covering material web position does not change as a result of a constantly clean deflection roller. A position control of the deflection roller is then not necessary, so that the inventive method without position control at least with regard to the inclination of the deflection roller manages.

Vorzugsweise wird die Umlenkrolle angetrieben.Preferably, the deflection roller is driven.

Eine besonders einfache Maßnahme zum Säubern der Umlenkrolle ist dann realisiert, wenn die Umfangsgeschwindigkeit der Umlenkrolle unterschiedlich zu der Bahngeschwindigkeit der Umhüllungsmaterialbahn ist. Hierzu ist vorzugsweise ein elektrischer Antrieb mittels eines Motors vorgesehen. Durch den vorherrschenden Schlupf der Umhüllungsmaterialbahn an der Umlenkrolle wird diese dauerhaft im Betrieb gesäubert. Vorzugsweise wird eine konstante Differenzgeschwindigkeit zwischen der Bahngeschwindigkeit der Umhüllungsmaterialbahn und der Umfangsgeschwindigkeit der Umlenkrolle eingestellt.A particularly simple measure for cleaning the deflecting roller is realized when the peripheral speed of the deflecting roller is different from the web speed of the wrapping material web. For this purpose, an electric drive is preferably provided by means of a motor. Due to the prevailing slippage of the wrapping material web on the deflection roller, it is permanently cleaned during operation. Preferably, a constant rate of difference between the web speed of the wrapping material web and the peripheral speed of the deflecting roller is set.

Eine Alternative bzw. eine ergänzende Ausführungsform liegt dann vor, wenn etwaige Verunreinigungen auf der Umfangsfläche der Umlenkrolle mit einem Schaber abgeschabt werden. Der Schaber ist vorzugsweise an der gegenüberliegenden Seite der Umhüllungsmaterialführung einwirkend auf die Umlenkrolle angeordnet. Zusätzlich oder alternativ kann auch eine Saugvorrichtung zum Absaugen der Verunreinigungen von der Umlenkrolle vorgesehen sein. Es könnte auch eine Saug-Schaber-Vorrichtung vorgesehen sein, die sowohl eine Saugwirkung als auch eine mechanische Schabwirkung auf der Umfangsfläche ausübt. Vorzugsweise ist die Umlenkrolle die nächste Rolle zur Formatvorrichtung, d.h. die nächste Rolle, die stromaufwärts zur Formatvorrichtung angeordnet ist.An alternative or a supplementary embodiment is when any impurities on the peripheral surface of the guide roller are scraped off with a scraper. The scraper is preferably on the opposite side of the wrapping material guide arranged acting on the pulley. Additionally or alternatively, a suction device for sucking the impurities from the deflection roller may be provided. It could also be provided a suction scraper device which exerts both a suction effect and a mechanical scraping action on the peripheral surface. Preferably, the pulley is the next roll to the format device, ie the next roll, which is arranged upstream of the format device.

Die Umlenkrolle umfasst vorzugsweise Öffnungen auf der Umfangsfläche, wobei die Umhüllungsmaterialbahn mit Saugluft an der Umlenkrolle gehalten wird. Durch diese Maßnahme kann besonders effizient der Schlupf und eine entsprechende Reibung ausgenutzt werden, um Verunreinigungen von der Umlenkrolle zu entfernen.The deflection roller preferably comprises openings on the circumferential surface, wherein the wrapping material web is held on the deflection roller with suction air. By this measure, the slip and a corresponding friction can be exploited particularly efficiently to remove impurities from the deflection roller.

Besonders bevorzugt ist das erfindungsgemäße Verfahren dann, wenn die Umhüllungsmaterialbahn stromaufwärts der Umlenkrolle mit Leim versehen wird. Diese Ausführungsform wird bevorzugt bei der Filterstrangherstellung, da bei dieser eine entsprechende Verklebung der Umhüllungsmaterialbahn schon vor der Formatvorrichtung stattfinden kann. Bei der Herstellung eines Zigarettenstrangs ist eine vorherige Beleimung auch möglich, allerdings aufgrund der Aufbringung von Tabak in Strangform auf eine Papierbahn dergestalt, dass Tabakpartikel bzw. Tabakmaterial sich auf einem Klebestreifen ablagern kann, weniger bevorzugt. Insbesondere kann es bei einer Umhüllungsmaterialbahn, die hochporös ist und insofern als Umhüllungsmaterialbahn für die Filterstrangherstellung besonders gut geeignet ist, vorkommen, dass Leim durch die Umhüllungsmaterialbahn tritt und besonders verstärkt die Umlenkrolle verunreinigt.The method according to the invention is particularly preferred when the wrapping material web is provided with glue upstream of the deflecting roller. This embodiment is preferred in the filter strand production, since in this a corresponding bonding of the wrapping material web can take place before the format device. In the production of a cigarette rod, a previous gluing is also possible, but due to the application of tobacco in strand form on a paper web such that tobacco particles or tobacco material can be deposited on an adhesive strip, less preferably. In particular, with a wrapping material web which is highly porous and insofar particularly suitable as a wrapping material web for the production of filter rods, glue may pass through the wrapping material web and contaminate the deflecting roller in a particularly reinforced manner.

Die Aufgabe wird ferner durch eine Umhüllungsmaterialbahnzuführungsvorrichtung mit einer Umlenkrolle zur Führung einer Umhüllungsmaterialbahn zu einer Formatvorrichtung, in der die Umhüllungsbahn um einen Filterstrang oder einen Tabakstrang wickelbar ist, wobei die Umlenkrolle angetrieben ist, wobei eine Vorrichtung zur Säuberung (Säuberungsvorrichtung) der Umfangsfläche der Umlenkrolle vorgesehen ist, gelöst.The object is further achieved by a wrapping material web feeding device with a deflection roller for guiding a wrapping material web to a format device, in which the wrapping web is wound around a filter strand or a tobacco rod, wherein the deflection roller is driven, wherein a device for cleaning (cleaning device) of the peripheral surface of the deflection roller is provided solved.

Durch die erfindungsgemäße Umhüllungsmaterialbahnzuführungsvorrichtung wird ein sehr ruhiger und sicherer Einlauf der Umhüllungsmaterialbahn in die Formatvorrichtung ermöglicht. Vorzugsweise umfasst die Säuberungsvorrichtung eine Steuerungsvorrichtung zur Einstellung einer von der Fördergeschwindigkeit der Umhüllungsmaterialbahn unterschiedlichen Umfangsgeschwindigkeit der Umlenkrolle. Vorzugsweise umfasst die Säuberungsvorrichtung einen Schaber, der mit der Umfangsfläche der Umlenkrolle im Eingriff steht. Alternativ oder zusätzlich zum Schaber kann auch eine Saugvorrichtung vorgesehen sein, die in Wirkverbindung mit der Umfangsfläche der Umlenkrolle steht. Bei der Umfangsfläche der Umlenkrolle handelt es sich um eine radial außen an der Umlenkrolle angeordneten Fläche, die parallel zur Rotationsachse der Umlenkrolle ist.The wrapping material web feed device according to the invention makes possible a very quiet and safe entry of the wrapping material web into the format device. The cleaning device preferably comprises a control device for setting a peripheral speed of the deflection roller which is different from the conveying speed of the wrapping material web. Preferably, the cleaning device comprises a scraper engaged with the peripheral surface of the diverting pulley. Alternatively or in addition to the scraper, a suction device may be provided which is in operative connection with the peripheral surface of the deflection roller. The circumferential surface of the deflection roller is a surface arranged radially on the outside of the deflection roller and parallel to the axis of rotation of the deflection roller.

Vorzugsweise ist die Umlenkrolle stromaufwärts der Formatvorrichtung die nächstliegende Rolle. Vorzugsweise umfasst die Umlenkrolle eine Saugvorrichtung zum Ansaugen der Umhüllungsmaterialbahn.Preferably, the diverting pulley upstream of the formatting device is the closest roll. Preferably, the deflection roller comprises a suction device for sucking the wrapping material web.

Eine erfindungsgemäße Strangmaschine der Tabak verarbeitenden Industrie, insbesondere Filterstrangmaschine, ist mit einer erfindungsgemäßen Umhüllungsmaterialbahnzuführungsvorrichtung, die vorstehend beschrieben ist, versehen.A strand machine according to the invention of the tobacco processing industry, in particular filter rod machine, is provided with a wrapping material web feeding device according to the invention, which is described above.

Die Erfindung wird nachstehend ohne Beschränkung des allgemeinen Erfindungsgedankens anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung beschrieben. Bezüglich aller im Text nicht näher erläuterten erfindungsgemäßen Einzelheiten wird ausdrücklich auf die Zeichnung verwiesen wird. Es zeigt:

Fig. 1
eine schematische Darstellung eines Teils einer erfindungsgemäßen Filterstrangmaschine.
The invention will be described below without limiting the general inventive idea by means of embodiments with reference to the drawing. With regard to all details of the invention not explained in detail, reference is expressly made to the drawings. It shows:
Fig. 1
a schematic representation of a part of a filter rod machine according to the invention.

Fig. 1 zeigt schematisch einen Teil einer erfindungsgemäßen Filterstrangmaschine 6, umfassend eine erfindungsgemäße Umhüllungsmaterialbahnzuführungsvorrichtung, insbesondere Papierbahnzuführungsvorrichtung 5. Fig. 1 schematically shows a part of a filter rod machine 6 according to the invention comprising a wrapping material web feeding device according to the invention, in particular paper web feeding device 5.

Eine Papierbahn 10 wird über Umlenkrollen 12, 13 und 14 einer Formatvorrichtung 15 zugeführt. Die Förderrichtung 11 der Papierbahn 10 ist auch schematisch dargestellt. Um die Lage der Papierbahn 10 konstant zu halten, sind Papierführungen 25 und 25' vorgesehen. Um eine ausreichende Papierspannung zu halten, insbesondere bei Versehen der Papierbahn 10 mit einem Leim beim Leimauftrag 16, sind außerdem Stützstäbe 26 vorgesehen. Der beim Leimauftrag 16 aufgebrachte Leim, beispielsweise durch nicht dargestellte Leimdüsen, wird durch eine Heizvorrichtung 27 wenigstens teilweise abgebunden.A paper web 10 is fed via deflection rollers 12, 13 and 14 of a format device 15. The conveying direction 11 of the paper web 10 is also shown schematically. In order to keep the position of the paper web 10 constant, paper guides 25 and 25 'are provided. In order to maintain a sufficient paper tension, in particular when the paper web 10 is provided with a glue during the glue application 16, supporting rods 26 are also provided. The glue applied during the glue application 16, for example by glue nozzles, not shown, is at least partially set by a heating device 27.

Bei dem verwendeten Papier handelt es sich vorzugsweise um hochporöses Papier, so dass der aufgetragene Leim 16 auch durch das Papier auf die dem Leimauftrag abgewandte Seite dringen kann, wodurch die Umlenkrolle 14 verschmutzen kann. Würde keine Maßnahme der Regelung der Lage der Papierbahn bzw. des Filterumhüllungspapiers durchgeführt werden, würde sich die Lage verändern, so dass ein sicherer Einlauf in die Formatvorrichtung 15 nicht mehr gewährleistet sein kann, da der Papierlauf unruhig wird.The paper used is preferably highly porous paper, so that the applied glue 16 can also penetrate through the paper onto the side facing away from the glue application, as a result of which the deflection roller 14 can become dirty. If no measure of the regulation of the position of the paper web or of the filter wrapping paper were to be carried out, the position would change, so that a safe entry into the format device 15 would take place can no longer be guaranteed because the paper run is restless.

Eine Regelung der Lage der Umlenkrolle 14 bzw. Neigung der Umlenkrolle 14, die auch Torpedo-Rolle genannt wird, um der Verschmutzung entgegen zu regeln, kann auch zu einem unruhigen Papierlauf führen.A regulation of the position of the guide roller 14 or inclination of the guide roller 14, which is also called torpedo roller to control the pollution, can also lead to a troubled paper run.

Überraschenderweise ist festgestellt worden, dass das Sauberhalten der Umlenkrolle 14 zu einem sicheren Einlauf und einem ruhigen Papierlauf in die Formatvorrichtung führt, ohne dass es einer gesonderten Regelung hierfür bedarf. Auf dem Weg bzw. in Förderrichtung 11 des Papierlaufs hinter der Umlenkrolle 14 wird in Förderrichtung 11' ein Filtermaterial 18 auf die Papierbahn 10 verbracht, um anschließend in der Formatvorrichtung 15 von der Papierbahn 10 bzw. dem Filterumhüllungspapier umhüllt bzw. umwickelt zu werden, so dass sich ein Filterstrang 17 mit Umhüllungspapier bzw. umhülltem Papier aus der Papierbahn 10 ergibt.Surprisingly, it has been found that keeping the guide roller 14 clean leads to a safe inlet and a smooth paper run into the format device, without the need for separate regulation for this purpose. On the way or in the conveying direction 11 of the paper path behind the guide roller 14, a filter material 18 is transported to the paper web 10 in the conveying direction 11 ', in order subsequently to be wrapped or wrapped in the format device 15 by the paper web 10 or the filter wrapping paper a filter strand 17 with wrapping paper or coated paper results from the paper web 10.

Zur Säuberung der Umlenkrolle 14 ist, wie in Fig. 1 schematisch dargestellt ist, eine Steuervorrichtung 19 vorgesehen, die über eine Verbindungsleitung 21 mit einem elektrisch angetriebenen Motor, der die Umlenkrolle 14 antreibt, verbunden. Die Steuervorrichtung 19 dient nun dazu, eine Differenzgeschwindigkeit zwischen der Fördergeschwindigkeit der Papierbahn 11 und der Umfangsgeschwindigkeit der Umlenkrolle 14 vorzusehen, beispielsweise eine schnellere Geschwindigkeit der Umfangsfläche der Umlenkrolle 14 im Vergleich zur Geschwindigkeit der Papierbahn 10, so dass der Schlupf zwischen dem Papier und der Umfangsfläche eine automatische Reinigung während des Betriebs der Filterstrangmaschine 6 ermöglicht. Hierdurch wird eine weitere Regelung der Lage des Papierlaufs überflüssig.To clean the guide roller 14, as in Fig. 1 is shown schematically, a control device 19 is provided, which is connected via a connecting line 21 with an electrically driven motor which drives the guide roller 14. The control device 19 now serves to provide a speed difference between the conveying speed of the paper web 11 and the peripheral speed of the guide roller 14, for example, a faster speed of the peripheral surface of the guide roller 14 compared to the speed of the paper web 10, so that the slip between the paper and the peripheral surface allows automatic cleaning during operation of the filter rod machine 6. As a result, a further control of the position of the paper path is unnecessary.

Die Steuervorrichtung 19 kann so ausgestaltet sein, dass die Bedienperson die Drehgeschwindigkeit der Umlenkrolle 14 unterschiedlich zu der Bahngeschwindigkeit 10 einstellen kann, wobei allerdings vorzugsweise eine Steuervorrichtung 19 vorgesehen ist, die von der Maschinensteuerung der Filterstrangmaschine 6 die Information erhält, mit welcher Geschwindigkeit die Maschine fährt bzw. mit welcher Papierbahngeschwindigkeit die Papierbahn 10 gefördert wird. Es ist dann möglich, eine konstante Differenzgeschwindigkeit einzustellen oder beispielsweise ein konstantes Verhältnis der Geschwindigkeit der Papierbahn zu der Umfangsgeschwindigkeit der Umlenkrolle.The control device 19 may be configured such that the operator can set the rotational speed of the deflection roller 14 differently from the path speed 10, although preferably a control device 19 is provided which receives information from the machine control of the filter rod machine 6 at which speed the machine travels or with which paper web speed the paper web 10 is conveyed. It is then possible to set a constant differential speed or, for example, a constant ratio of the speed of the paper web to the peripheral speed of the deflection roller.

Zum Sauberhalten der Umfangsfläche der Umlenkrolle 14 kann auch ein Schaber 20 Verwendung finden, der an der Umfangsfläche entlang schabt. Als weitere alternative Ausführungsform kann zusätzlich zum Schaber 20 eine Saugvorrichtung vorgesehen sein, die allerdings in Fig. 1 nicht dargestellt ist. Es kann auch eine Saug-Schaber-Vorrichtung vorgesehen sein.To keep the circumferential surface of the guide roller 14 clean, a scraper 20 can also be used which scrapes along the peripheral surface. As a further alternative embodiment, in addition to the scraper 20, a suction device may be provided which, however, in Fig. 1 not shown. It may also be provided a suction scraper device.

Mit dem Schaber bzw. einer Saug-Schaber-Vorrichtung, die die Umfangsfläche der Umlenkrolle 14 im Betrieb sauber hält, ist ein kontinuierliches Reinigen im Betrieb ermöglicht oder ein temporäres Reinigen, wobei beispielsweise eine Reinigung erst dann stattfindet, wenn eine Verunreinigung der Umfangsfläche erfolgt ist. Hierzu ist ein entsprechender Sensor vorgesehen, der beispielsweise den Durchmesser der Umlenkrolle 14 bzw. den Durchmesser der Umfangsfläche der Umlenkrolle 14 misst oder die Reflexion der Umfangsfläche der Umlenkrolle 14, wobei die Messwerte mit Vorgabewerten verglichen werden und bei einer zu großen Abweichung der Messwerte von den Vorgabewerten bzw. Sollwerten eine Säuberung geschieht.With the scraper or a suction scraper device that keeps the peripheral surface of the guide roller 14 clean during operation, a continuous cleaning during operation or a temporary cleaning is possible, for example, a cleaning takes place only when contamination of the peripheral surface has occurred , For this purpose, a corresponding sensor is provided which measures, for example, the diameter of the deflection roller 14 or the diameter of the peripheral surface of the deflection roller 14 or the reflection of the peripheral surface of the deflection roller 14, the measured values being compared with default values and, if the measured values are too great Default values or setpoints a purge happens.

Die Maßnahme eines Schlupfes der Papierbahn 10 im Verhältnis zur Umfangsfläche der Umlenkrolle 14 kann alleine durchgeführt werden oder in Kombination mit einem Schaber und/oder einer Saugvorrichtung.The measure of slippage of the paper web 10 in relation to the circumferential surface of the deflection roller 14 can be carried out alone or in combination with a scraper and / or a suction device.
