Description

Die Erfindung bezieht sich auf eine Notvorrichtung, die beim Riß einer Papierbahn in einer sich im Betriebszustand befindenden rotierenden Druckmaschine aktiviert wird.The invention relates to an emergency device when a paper web breaks in a rotating printing press which is in the operating state is activated.

Die Druckschrift EP 0 654 433 A1 beschreibt eine Vorrichtung zur Vermeidung von Schäden beim Riß der Materialbahnen in einer rotierenden Druckmaschine. Mit eine derartigen Vorrichtung können die Schäden vermieden werden, die von den abgerissenen Bahnen an den Produktions-vorrichtungen verursacht werden, die Drehzylinder bevorzugt Drucktuch-Zylinder der rotierenden Druckmaschinen umfassen, wobei Steuerkupplungen eingesetzt werden. Nach der Lehre dieser Druckschrift läuft die Papierbahn teilweise um eine drehbar montierte Leitwalze herum und Rollen sind vorgesehen, um die Bahn an dieser Walze einzuspannen. Diese Walze wird von einer Steuerkupplung in der Papierbahnlaufrichtung gesteuert.EP 0 654 433 A1 describes a device for avoiding Damage when the web of material breaks in a rotating printing machine. With one Such device can avoid the damage caused by the demolished Paths are caused on the production fixtures, which preferred rotary cylinders Blanket cylinders of rotating printing presses include control clutches be used. According to the teaching of this document, the paper web runs partially a rotatably mounted idler roll around and rollers are provided around the web of this roller. This roller is driven by a control clutch in the Paper web direction controlled.

Mit dieser Vorrichtung können die Zylinder der Druckeinheit wirksam bei einem Bahnriß geschützt werden; jedoch kann die abgerissene Bahn ungehindert aus einem nach dem Trockner angeordneten Kühlungswalzenabschnitt herausgleiten oder aus der Superstruktur von Wendestangen herauslaufen.With this device, the cylinders of the printing unit can be effective in the event of a web break to be protected; however, the torn web can move freely from one to the other Dryer arranged cooling roller section slide out or out of the superstructure run out of turning bars.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine neue Notvorrichtung zu schaffen, bei welcher es möglich ist, in einer Druckmaschine nach dem Papierbahnriß den Durchgang der Papierbahn zu erhalten, die in die Bauteile der rotierenden Druckmaschine eingeführt worden ist.The object of the invention is therefore to create a new emergency device, in which it is possible in a printing machine after the paper web tear Passage of the paper web to get into the components of the rotating printing press has been introduced.

Nach einem wesentlichen Merkmal der erfindungsgemäßen Vorrichtung weist sie in der Nähe einer die bereits gedruckten Papierbahn führenden Walze einen Abwickler auf, um welchen herum eine Vorratspapierbahn aufgewickelt ist, und Mittel zur Verbindung der besagten Vorratspapierbahn mit der bereits gedruckten Papierbahn, um deren Durchgang in einem nach dem besagten Abwickler liegenden Maschinenteil zu erhalten. According to an essential feature of the device according to the invention, it points in the Close an unwinder to a roller that guides the already printed paper web which around a supply paper web is wound up, and means for connecting the said stock paper web with the already printed paper web in order to pass it in to obtain a machine part lying after said unwinder.

Ein besonderer Vorteil der Lösung besteht erfindungsgemäß darin, daß bei einem plötzlichen Papierbahnriß in der Maschine ein zu verarbeitender Bahnteil in der Maschine im eingeführten Zustand bleiben kann und besonders der Bahnteil, der sich in den von außen am schwersten zugänglichen Bereichen befindet. Mit der äußerst schnellen Positionierung des Abwicklers in Einsatz-bereitschaftsstellung in der beim Auftreten eines Bahnrisses bremsenden Maschine ist es möglich, den meistens sekundenlangen Leerlaufbetrieb der rotierenden Maschine auszunutzen, um die Vorratsbahn mit der bereits gedruckten Bahn zu verbinden. Im Leerlaufbetrieb der rotierenden Maschine werden die verbundenen Bahnen - die bereits gedruckte Bahn und die ungedruckte Bahn - durch die Bauteile der Maschine, wie den Kühlungswalzenabschnitt, die Superstruktur von Wendestangen und den Trichter der Falzmaschine, geführt, so daß das Papier in diesen Bauteilen weiterhin hindurch geführt werden kann. Der Durchlaufweg der Papierbahn mindestens in einem Teil der Maschine wird somit gespeichert und der Wiederanlauf der Maschine sowie deren Hochlauf können sehr schnell durchgeführt werden.A particular advantage of the solution according to the invention is that in one sudden paper web break in the machine a web part to be processed in the machine can remain in the imported state and especially the part of the track that is in the most difficult to access areas outside. With the extremely fast Positioning of the unwinder in the operational standby position in the event of a Web break braking machine, it is possible, mostly seconds Idle operation of the rotating machine to take advantage of the supply path with the already to connect printed web. When the rotating machine is idling, the connected webs - the already printed web and the unprinted web - through the Components of the machine, such as the cooling roller section, the super structure of Turning bars and the hopper of the folding machine, guided, so that the paper in this Components can still be passed through. The path of the paper web at least in part of the machine is saved and the restart of the The machine and its run-up can be carried out very quickly.

Nach weiteren Merkmalen der Notvorrichtung ist der Abwickler erfindungsgemäß gegenüber der gedruckten Papierbahn derart positioniert, daß die Vorratspapierbahn und die gedruckte Papierbahn gegebenenfalls aneinander abgestutzt werden können und daß die Bahn ungehindert im normalen Betriebszustand durchlaufen kann. Der Abwickler kann auf einem schwenkbaren Halter montiert werden und die Vorratspapierbahn kann an der durchlaufenden Papierbahn mittels eines Positionierungselements zur Anlage kommen. Das letztere kann aus einem durch ein Druckmedium gesteuerten Zylinder bestehen. Der sich außer Betrieb befindende Abwickler wird in einem möglichst geringen Abstand von der Durchlaufebene der gedruckten Bahn montiert, um eine schnelle Verbindung der Vorratsbahn und des gedruckten Bahnteiles zu gewahrleisten, der im Montagebereich des Abwicklers vorbeiläuft. Die Strecke der Positionierung in die Einsaztbereitschaftsstellung ist somit äußerst kurz. Die Vorratspapierbahn hat auf der der gedruckten Papierbahn zugewandten Seite Klebemittel, wie Kiebebänder oder ähnliches. Diese können im Abstand voneinander auf der Breite der Vorratsbahn oder mittig und entlang der Laufrichtung der besagten Bahn angebracht werden. According to further features of the emergency device, the unwinder is in accordance with the invention positioned opposite the printed paper web in such a way that the stock paper web and the printed paper web can optionally be braced against each other and that the Can run freely through the normal operating state. The unwinder can can be mounted on a swiveling holder and the stock paper web can be attached to the continuous paper web come to rest by means of a positioning element. The latter can consist of a cylinder controlled by a pressure medium. Of the Unwinder will be as close as possible to the pass-through level of the printed web is assembled for a quick connection of the To ensure supply rail and the printed web part in the assembly area of the Unwinder passed. The distance of positioning in the standby position is therefore extremely short. The stock paper web has on the printed paper web facing side adhesive, such as tape or the like. These can be in Distance from each other on the width of the supply path or in the middle and along the Direction of travel of said web can be attached.

Die Geschwindigkeit des mit der Vorratspapierbahn versehenen Abwicklers wird auf die Drehzahl der Maschine durch ihm zugeordnete Steuermittel beschleunigt und daran gehalten, um eine möglichst reibungslose Verbindung der ungedruckten Vorratspapierbahn mit der gedruckten Papierbahn beim Riß derselben zu garantieren. Die Steuerung kann an dem Außenumfang der Aufwicklung der Vorratsbahn mit Hilfe eines Antriebsriemens angreifen; die Steuerung kann ebenso gut unmittelbar auf den Drehzapfen des Abwicklers wirken.Beide Steuerungsformen sind zur Anpassung der Drehgeschwindigkeit ausgebildet, um die Änderung des Durchmessers der Aufwicklung der Vorratsbahn auf den Abwickler auszugleichenThe speed of the unwinder provided with the stock paper web is reduced to the The speed of the machine is accelerated by the control means assigned to it and by it kept in order to connect the unprinted stock paper web as smoothly as possible guarantee with the printed paper web when it tears. The control can the outer circumference of the winding of the supply web with the help of a drive belt attack; the control can also be placed directly on the pivot of the unwinder Both forms of control are designed to adjust the rotational speed, the change in the diameter of the winding of the supply web on the unwinder balance

Die Aufwicklung der Vorratsbähn 21 auf dem Abwickler 14 bildet eine Kleinrolle 14a. Die Kleinrolle 14a kann das Endstück einer Rolle sein, das einen geringeren Bahnvorrat hat als den einer vollen Rolle. Die Kleinrolle 14a ist in dem Halter 16 durch einen Achszapfen 15 drehbar gelagert. Ein Positionierungselement 24 - zum Beispiel ein Zylinder - kann den Halter 16 um die Achse 25 in der Richtung des Doppelpfeiles 29 drehen lassen. Die Funktion des Positionierungselementes 24 kann durch Zufuhr eines pneumatischen oder hydraulischen Druckmediums erfolgen. Die Abstützung der ungedruckten Vorratsbahn 21 der Kleinrolle 14a kann zur Gewährleistung der rechtzeitigen Verbindung mit der gedruckten Bahn 22 sehr rasch durchgeführt werden. Hierzu liegt die Kleinrolle 14a in Ruhestellung nur in einem sehr geringem Abstand 27 von der laufenden gedruckten Bahn 22. Daher ist die Abstützungsstrecke der Vorratsbahn 21 an die laufende gedruckte Bahn 22 äußerst kurz.As can be seen in FIG. 2, the emergency device according to the invention comprises one Unwinder 14, which is mounted in a pivotable holder 16 and on which one Stock paper web 21 is wound. The winding of the supply web 21 on the Unwinder 14 forms a small roll 14a. The small roll 14a can be the end piece of a roll be that has a lower rail stock than that of a full roll. The small roll 14a is is rotatably supported in the holder 16 by an axle pin 15. A Positioning element 24 - for example a cylinder - can hold the holder 16 around the Let axis 25 turn in the direction of double arrow 29. The function of the Positioning element 24 can be supplied by a pneumatic or hydraulic Print medium. The support of the unprinted supply web 21 of the Small roll 14a can ensure timely connection with the printed Lane 22 can be carried out very quickly. For this purpose, the small roll 14a is in the rest position only a very short distance 27 from the running printed web 22. Therefore the support path of the supply web 21 to the running printed web 22 extremely short.

Die drehbar gelagerte Kleinrolle 14a ist mit Haftmitteln 28 zur Verbindung der Vorratsbahn 21 mit der gedruckten Bahn 22 versehen. Diese Haftmittel 28 können voneinander auf der Breite der Vorratsbahn 21 beabstandet sein oder es kann sich ebenfalls um einzelne Klebebänder handeln, zum Beispiel doppelseitig haftend, die in der Mitte der der gedruckten Papierbahn der bei der Umfangsfläche der Kleinrolle 14a liegenden Vorratsbahn zugewandten Seite befestigt sind. Es ist jedoch ebenfalls möglich, ein Haftmittel 28 zu verwenden, das in Form einzelner durchgehender Streifen auf der Breite der Vorratswalze angebracht werden kann. Es wäre außerdem möglich, eine Vorrichtung zum Aufbringen eines flüssigen Klebers auf der gedruckten Bahn 22 oder auf der Vorratsbahn 21 vorzusehen.The rotatably mounted small roller 14a is with adhesive 28 for connecting the Supply web 21 provided with the printed web 22. This adhesive 28 can be spaced apart from one another on the width of the supply web 21 or it can also be are single tapes, for example double-sided adhesive, which in the middle of the the printed paper web lying on the peripheral surface of the small roll 14a Storage lane facing side are attached. However, it is also possible to use a Adhesive 28 to use, which is in the form of individual continuous strips across the width the supply roller can be attached. It would also be possible to have a device for applying a liquid adhesive on the printed web 22 or on the Provide supply track 21.

Wie in Figur 2 ersichtlich, ermöglicht eine auf dem schwenkbaren Halter 16 vorgesehene Steuervorrichtung die Beschleunigung der Vorratsbahn 21, die mit der Maschinengeschwindigkeit abgewickelt ist, das heißt mit der Papierlaufgeschwindigkeit, und anschließend diese Geschwindigkeit beizubehalten. Die Steuerung 18 - ein Elektromotor oder ähnliches - ist an dem Halter 16 befestigt und wirkt auf einen oder mehrere Antriebsriemen 17, die ihrerseits auf Umlenkrollen 19 und auf Spannrollen 20 geführt sind. Die Spannrolle 20 kann den ursprünglichen Zug und die stets wechselnde daraus resultierende Spannkraft des Antriebsriemens 17 oder der Riemen 17 am Umfang der Kleinrolle 14a ausgleichen. Bei einem Bahnriß und der Abstützung der Vorratsbahn 21 an die gedruckte Bahn 22 nimmt der Durchmesser der Kleinrolle 14a rasch ab, da die nun verbundenen Papierbahnen 21, 22 die anderen Bauteile kontinuierlich durchlaufen, wie die Gruppe 7 von Kühlungswalzen und die Superstruktur 10 von Wendestangen oder den Falztrichter 11, um den Papierdurchgang 38 nicht zu verlieren.As can be seen in FIG. 2, one provided on the pivotable holder 16 enables Control device the acceleration of the supply path 21, which with the Machine speed is processed, i.e. with the paper running speed, and then keep that speed. The controller 18 - a Electric motor or the like - is attached to the holder 16 and acts on one or a plurality of drive belts 17, which in turn are on deflection rollers 19 and on tensioning rollers 20 are led. The tension roller 20 can the original train and the always changing resulting tension of the drive belt 17 or the belt 17 on the circumference compensate for the small roll 14a. If the web breaks and the supply web 21 is supported to the printed web 22, the diameter of the small roll 14a rapidly decreases as the now connected paper webs 21, 22 continuously run through the other components, such as the Group 7 of cooling rolls and the superstructure 10 of turning bars or the Folding former 11 in order not to lose the paper passage 38.

Statt einer Wirkung einer Steuerung auf dem außen liegenden Umfang der Aufwicklung der Vorratsbahn 21 kann der Zapfen 15 des Abwicklers 14 direkt angetrieben werden Diese Steuerung paßt dann die Geschwindigkeit der Kleinrolle 14a dem rasch abnehmenden Durchmesser der Kleinrolle 14a an, das heißt, die Steuerung 18 treibt zwangsläufig die Kleinrolle 14a mit einer nach und nach zunehmenden Drehzahl zur Sicherung einer konstanten Abwicklung an.Instead of an effect of a control on the external extent of the winding the supply path 21, the pin 15 of the unwinder 14 can be driven directly This control then quickly adjusts the speed of the small roll 14a decreasing diameter of the small roll 14a, that is, the controller 18 drives inevitably the small roller 14a with a gradually increasing speed to Ensuring a constant settlement.

Der Halter 16 der Kleinrolle 14a ist gegenüber einer Leitwalze 26 angeordnet, auf welcher die bereits gedruckte Papierbahn läuft. Wenn eine Abstützung durch einen Riß der gedruckten Bahn ausgelöst ist, stützt sich die Kleinrolle 14a an die Leitwalze 26 ab, auf welche die gedruckte Bahn 22 läuft, so daß eine Verbindung zwischen der gedruckten Bahn und der ungedruckten Vortatsbahn sichergestellt werden kann. Es ist daher sicher, daß die Abstützungsbewegung der Kleinrolle 14a nicht ins Leere fällt, sondern auf der gedruckten Papierbahn 22 landet. Der Pfeil 23 deutet auf die ursprüngliche Laufrichtung der gedruckten Papierbahn 22 auf ihrem Weg 38. The holder 16 of the small roller 14a is arranged opposite a guide roller 26 on which the already printed paper web is running. If a support is caused by a crack in the printed web is triggered, the small roller 14a is supported on the guide roller 26 on which runs the printed web 22 so that a connection between the printed Bahn and the unprinted Vortatsbahn can be ensured. It is therefore certain that the support movement of the small roll 14a does not fall into void, but on the printed paper web 22 lands. The arrow 23 points to the original running direction the printed paper web 22 on its way 38.

Nach einer in Figur 3 dargestellten Weiterbildung ist der Abwickler 14 auf einer Achse 25 montiert, die selber in seitlichen Flanschen 31, 32 montiert ist. Diese, die auf der Zeichnung lediglich angedeutet sind, können seitliche Trennwände oder der Mantel eines Trockners 6, der Gruppe 7 von den Kühlungswalzen oder der Bühne 9 sein. Der Abwickler 14, der mit seiner Vorratsbahnaufwicklung versehen ist, kann ebenfalls auf der Falzmaschine 8 oder auf dem Trichter ihrer ersten Längsfalzvorrichtung 11 montiert werden. In der Darstellung nach Figur 3 ist der Abwickler 14 in Haltern 16 montiert, von denen einer durch eine Gabel 33 mit einem Zylinder 24 verbunden ist. Dieser kann pneumatisch oder hydraulisch angetrieben sein - wie bereits erwähnt -. Obwohl es nicht ausdrücklich in Figur 3 dargestellt ist, befindet sich die Kleinrolle 14a in Ruhestellung im geringen Abstand von der Druckbahn 22, die auf der Leitwalze 26 in der Richtung 23 läuft. In dieser Ausführungsform greift eine Steuerung 17, 18, 19 teilweise an dem Umfang der Kleinrolle 14 an und nimmt sie mit. Die Steuerung 18 sorgt dafür, die Kleinrolle 14 auf die Geschwindigkeit der Maschine zu bringen und sie daran zu halten. Bei einem Bahnriß erfolgen die Bewegung der Abstützung der Vorratsbahn 21 an die gedruckte Bahn 22 und deren Verbindung unverzüglich. Das Einführen der nun verbundenen Bahnen 21 und 22 in die Gruppe 7 von den Kühlungswalzen und in die Superstruktur von Wendestangen, einschließlich in die erste Längsfalzeinrichtung 11 findet während der Maschinenverzogerung innerhalb der sich bis zum vollständigen Bremsen und Stillstand der Maschine ablaufenden Zeitspanne statt. Der Durchgang 38 des Papiers, dessen Einführen umständlich gewesen ist, bleibt somit erhalten. Der Wiederanlauf der Maschine kann also viel schneller erfolgen.According to a development shown in FIG. 3, the unwinder 14 is on an axis 25 mounted, which itself is mounted in side flanges 31, 32. These that on the Drawing are only indicated, side partitions or the jacket of a Dryer 6, the group 7 from the cooling rollers or the stage 9. Of the Unwinder 14, which is provided with its supply rewinder, can also on the Folding machine 8 or mounted on the hopper of its first longitudinal folding device 11 become. In the illustration according to FIG. 3, the unwinder 14 is mounted in holders 16 from one of which is connected to a cylinder 24 by a fork 33. This can be pneumatically or hydraulically driven - as already mentioned -. Although it is not is expressly shown in Figure 3, the small roller 14a is in the rest position in small distance from the printing web 22, which runs on the guide roller 26 in the direction 23. In this embodiment, a controller 17, 18, 19 partially engages the circumference of the Small roll 14 and takes it with you. The controller 18 ensures that the small roll 14 on the Bring speed to the machine and keep it at it. In the event of a web break the movement of the support of the supply web 21 to the printed web 22 and their connection immediately. The introduction of the now connected webs 21 and 22 in group 7 from the cooling rolls and into the superstructure of turning bars, including in the first longitudinal folding device 11 takes place during the Machine lag within the itself until complete braking and standstill period of time running out of the machine. The passage 38 of the paper, the Introduction has been cumbersome, is retained. The restart of the machine can be done much faster.

Die Funktion der Noteinrichtung während des Maschinenbetriebs wird erfindungsgemäß mit Bezug auf die Figuren 4a bis 4c näher erläutert.The function of the emergency device during machine operation is according to the invention explained in more detail with reference to Figures 4a to 4c.

Eine hinter der letzten Druckgruppe angeordnete Bahnfangvorrichtung 5, ein Trockner 6 mit kontinuierlichem Durchlauf sowie zum Beispiel eine Gruppe 7 von Kühlungswalzen sind in der Figurenreihe 4a bis 4c dargestellt. Der mit 38 bezeichnete Papierdurchgang führt in die Superstruktur 10 von Wendestangen - der wie schematisch in Figur 1 angedeutet über einer ersten Längsfalzvorrichtung 11 liegt, die sich über einer Falzmaschine 8 befindet. In dem besonderen dargestellten Beispiel ist die Kleinrolle 14a der Notvorrichtung gegenüber einer ersten Kühlungswalze 30 der Gruppe 7 angebracht; ein Zylinder 24 sowie eine Steuerung 17 sind ihr zugeordnet. Der vor dem Trockner 6 montierte Bahnfänger 5 umfaßt eine Gruppe von zwei Walzen 37 sowie einen Lager-und Makulaturentsorgungskasten. Ein der Bahnfangeinrichtung 5 zugeordneter Detektor 34 erfaßt das Auftreten eines Bahnrisses und verursacht die Abstützung der Vorratspapierbahn 21 an die bereits gedruckte Bahn 22. Der Trockner 6 umfaßt Eingangs-und Ausgangsöffnungen 35, 36 zum Durchlauf der gedruckten Bahn 22. Im in Figur 4a dargestellten Zustand läuft die gedruckte Bahn 22 mit der Maschinengeschwindigkeit - zum Beispiel 10 m/sek. Die über der ersten Kühlungsrolle 30 angeordnete Kleinrolle 14a läuft mit einer Geschwindigkeit, die die Verbindung der Bahnen ohne Verzug während des Betriebs der rotierenden Druckmaschine mit der Druckgeschwindigkeit ermöglicht. Dies ist wichtig, um einen Riß der Vorratsbähn 21 hinter der Verbindungsstelle der Bahnen 21, 22 durch plötzliches Auftreten von Zugkräften am Ende dieser Verbindung zu vermeiden. Beim Auftreten eines in Figur 4b angedeuteten Risses lockert sich der Bahnzug schlagartig. Der Detektor 34 schaltet das Bahnfanggerät 5 unverzüglich ein, das Bremsen der Druckmaschine, das durch das Auftreten des Risses ausgelöst wird, ermöglicht innerhalb einer Übergangszeitspanne von einigen Sekunden, die Beförderung des Bahnvorrats fortzusetzen, der nun in den Makulaturbehälter vor dem Durchlauf durch den Trockner 6 geführt wird, wie ubrigens in Figur 4c gezeigt. Hierzu sind die in dem Bahnfanggerät 5 angeordnete Gruppe von zwei Walzen 37 sowie der unter derselben angebrachte Makulaturbehälter vorgesehen.A web catching device 5 arranged behind the last printing group, a dryer 6 with continuous flow and for example a group 7 of cooling rolls are shown in the series of figures 4a to 4c. The paper passage designated 38 leads into the superstructure 10 of turning bars - which as shown schematically in FIG. 1 indicated above a first longitudinal folding device 11, which is above a Folding machine 8 is located. In the particular example shown, the small roll is 14a attached to the emergency device opposite a first cooling roller 30 of group 7; a Cylinder 24 and a control 17 are assigned to it. The one before the dryer 6 assembled web catcher 5 comprises a group of two rollers 37 and a bearing and Waste disposal box. A detector 34 assigned to the web catching device 5 detects the occurrence of a web break and causes the support of the Stock paper web 21 to the already printed web 22. The dryer 6 comprises input and Exit openings 35, 36 for the passage of the printed web 22. In Figure 4a shown state, the printed web 22 runs at the machine speed - for example 10 m / sec. The small roll 14a arranged above the first cooling roll 30 runs at a speed that connects the webs without delay during the Operation of the rotating printing machine at the printing speed allows. This is important to tear the supply web 21 behind the junction of the webs 21, 22 by suddenly occurring tensile forces at the end of this connection. When a crack indicated in FIG. 4b occurs, the web tension loosens suddenly. The detector 34 switches on the webbing device 5 immediately, braking the Printing machine that is triggered by the occurrence of the tear allows inside a transition period of a few seconds, the transportation of the rail supply to continue, which is now in the waste container before passing through the dryer 6 is performed, as incidentally shown in Figure 4c. For this purpose, those in the web catching device 5 arranged group of two rollers 37 and the one mounted below it Waste bin provided.

Die Maschine wird beim Auftreten des Bahnrisses bis zum Stillstand ca. 6 Sekunden lang gebremst. Bei einer Bahngeschwindigkeit von ca. 10 m/sek. können innerhalb dieser Zeitspanne noch bis 40 m Bahn in die Maschine eingeführt werden. Der abgerissene Teil der gedruckten Bahn 22 wird weiter auf den angesteuerten Kühlungswalzen in die Superstruktur von Wendestangen und in die erste Längsfalzvorrichtung 11 geführt, er ist dann aus dem Papierdurchgang 38 herausgenommen, wenn keine Vorsichtsmaßnahmen getroffen werden. Der Abwickler 14, der mit seiner Vorratsbahn 21 versehen und von dem Detektor 34 angeschaltet ist, wird unverzüglich nach dem Auftreten des Bahnrisses an die gedruckte Bahn 22 zur Anlage gebracht, das am Umfang der Kleinrolle 14a liegende Haftmittel 28 führt zu einer Klebeverbindung der Vorratsbahn 21 mit der Druckbahn 22; die Leerlaufdrehbewegung der Kühlungswalzen 30 der Gruppe 7 sowie die der in der Superstruktur 10 von Wendestangen liegenden Zugwalzen führen dann die verbundenen Bahnen 21, 22 um diese Walzen 30 herum und den Weg des Papierdurchganges 38 entlang in die Superstruktur 10 und in die erste Längsfalzvorrichtung bis zum Stillstand der Maschine. Es gibt zwar keine Bahn mehr in dem Trockner 6, die Bahn 21, 22 verbleiben aber den Papierdurchgang 38 entlang in der Gruppe 7 von Kühlungsrollen bis an dem Falztrichter 11. Somit bleibt der Papierdurchgang 38 in den schwer zugänglichen Bauteilen der Maschine erhalten, wie in der Gruppe 7 von Kühlungswalzen oder der Superstruktur 10 von Wendestangen, einschließlich in dem Falztrichter 11, ohne daß es notwendig ist, mühsam die Bahn oder die Bahnen erneut in diese Bauteile einzuführen.When the web break occurs, the machine stops for about 6 seconds slowed down. At a web speed of approx. 10 m / sec. can within this Time period up to 40 m web can be introduced into the machine. The demolished part the printed web 22 is continued on the driven cooling rollers in the Superstructure of turning bars and guided into the first longitudinal folding device 11, it is then taken out of the paper passage 38 if no precautions to be hit. The unwinder 14, which is provided with its supply web 21 and from which Detector 34 is switched on, is immediately after the occurrence of the web break to the printed web 22 brought to rest, the lying on the circumference of the small roll 14a Adhesive 28 leads to an adhesive connection of the supply web 21 to the printing web 22; the idle rotation of the cooling rollers 30 of group 7 and that in the Superstructure 10 of pull rolls lying on turning bars then guide the connected ones Tracks 21, 22 around these rollers 30 and along the path of the paper passage 38 into the superstructure 10 and into the first longitudinal folding device until the Machine. There is no longer any web in the dryer 6, the web 21, 22 remain but along the paper passage 38 in the group 7 of cooling rolls up to that Folding former 11. The paper passage 38 thus remains in the components which are difficult to access of the machine, as in group 7 of cooling rolls or superstructure 10 of turning bars, including in the former 11, without the need for laboriously reintroducing the web or webs into these components.

Die erfindungsgemäße Noteinrichtung kann nicht nur auf der Gruppe 7 von Kühlungswalzen sondern auch auf dem Trockner 6 am Ausgang der Superstruktur 10 von Wendestangen sowie in der Falzmaschine 8 über dem Falztrichter 11 angeordnet werden.The emergency device according to the invention can not only on group 7 of Cooling rollers but also on the dryer 6 at the exit of the superstructure 10 from Turning bars and in the folding machine 8 can be arranged above the former 11.
