Abstract

The invention relates to a device for measuring a location of webs, comprising: a multitude of entry positions for the webs; a multitude of first exit positions (A2, A3) for the webs, to which a web can be fed by guiding it straight ahead from first assigned entry positions; at least one second exit position (A1), to which a web can be fed only by laterally displacing the web; means for laterally displacing a web, and; at least one sensor (06, 08) for detecting a location of webs. The sensor (06, 08) can be displaced between a position for detecting the location of a web at one of the exit positions and a position for detecting the location of a web at the second exit position. This enables one of the sensors to be eliminated.

Description

Die Erfindung betrifft eine Vorrichtung zur Messung einer Lage, insbesondere eines Längsregisters, von Materialbahnen gemäß dem Oberbegriff des Anspruchs 1 oder 3.The invention relates to a device for measuring a layer, in particular a longitudinal register, of material webs according to the preamble of claim 1 or 3.

Aus der EP 09 50 519 A1 ist beispielsweise eine Druckmaschine bekannt, wobei die Registerhaltigkeit in Transportrichtung der Bahn über einen Messfühler ermittelt, und durch eine Regeleinrichtung bei Bedarf korrigiert wird.From EP 09 50 519 A1, for example, a printing machine is known, wherein the register accuracy in the transport direction of the web determined by a sensor, and is corrected by a control device if necessary.

Die DE 42 03 947 A1 zeigt ein Verfahren zum Einstellen eines die Bahnkante einer laufenden Materialbahn berührungsfrel erfassenden Fühlers. Der Fühler kann durch ein Fühlerverstellgerät verstellt werden, um eine Änderung des zu regelnden Materials und/oder eine Fühlerverschmutzung in einfacher Weise kompensieren zu können. Dazu wird das Fühlerverstellgerät durch eine elektronische Signalverarbeitungseinrichtung zur Ausführung einer Verstellbewegung quer zur Bahnkante angesteuert.DE 42 03 947 A1 shows a method for setting a web edge of a moving material web contact feeler detecting sensor. The sensor can be adjusted by a sensor adjustment device to compensate for a change in the material to be controlled and / or sensor fouling in a simple manner. For this purpose, the Fühlerverstellgerät is driven by an electronic signal processing device for performing an adjustment transversely to the web edge.

Die GB 2313 831 A offenbart eine Druckmaschine mit zwei zur Laufrichtung zueinander versetzten Laufwegen für den Transport von Materialbahnen. Jedem der beiden Laufwege ist ein eigener Sensor zur Erfassung der Bahnkanten zugeordnet.GB 2313 831 A discloses a printing machine with two offset to the direction of each other running paths for the transport of material webs. Each of the two paths is assigned its own sensor for detecting the web edges.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Messung einer Lage von Materialbahnen zu schaffen.The invention has for its object to provide a device for measuring a layer of webs.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 oder 3 gelöst.The object is achieved by the features of claim 1 or 3.

Eine solche Vorrichtung erlaubt es, den Sensor sowohl zur Erfassung der Lage einer Materialbahn einzusetzen, die durch Geradeausführung einer ersten Ausgangsposition zugeführt wird, als auch denselben Sensor zur Erfassung der Lage einer Materialbahn einzusetzen, die durch seitliche Versetzung einer zweiten Ausgangsposition zugeführt wird. Ein zusätzlicher Sensor zur Erfassung der Lage einer Materialbahn an der zweiten Ausgangsposition wird dadurch überflüssig.Such a device makes it possible to use the sensor both for detecting the position of a material web, the straight through a first starting position is fed, as well as to use the same sensor for detecting the position of a web, which is supplied by lateral displacement of a second starting position. An additional sensor for detecting the position of a material web at the second starting position becomes superfluous.

Beispielsweise lassen sich bei handelsüblichen Zeitungsmaschinen dank der Vorrichtung bis zu zwei Dutzend Sensoren einsparen. Da ein Sensor mit einem umfangreichen Verbund an Steuerungen, Steuerungselementen und Befestigungen korreliert, bedeutet die Einsparung eines Sensors eine erhebliche Reduktion an finanziellem und technischem Aufwand.For example, can be saved in commercial newspaper machines thanks to the device up to two dozen sensors. Because a sensor correlates with a vast array of controls, controls, and fixtures, saving a sensor means significantly reducing capital and engineering costs.

In einer Ausführungsform der Erfindung werden die Materialbahnen an ihren Eingangs- und Ausgangspositionen über Leitwalzen geführt. Dabei kann es vorteilhaft sein, dass eine Leitwalze für alle Ausgangspositionen der Materialbahnen vorhanden ist.In one embodiment of the invention, the webs are guided at their entry and exit positions via guide rollers. It may be advantageous that a guide roller for all initial positions of the material webs is present.

Gemäß einer anderen Ausführungsform der Erfindung sind für die ersten Ausgangspositionen und für die zweiten Ausgangspositionen getrennte Leitwalzen vorhanden. Wesentlicher Vorteil dieser Ausführungsform ist ein geringeres Gewicht einer Walze, die somit einer Bremsung oder Beschleunigung der Materialbahn schneller folgen kann.According to another embodiment of the invention, separate guide rolls are provided for the first home positions and for the second home positions. The essential advantage of this embodiment is a lower weight of a roller, which can thus follow a braking or acceleration of the web faster.

In einer bevorzugten Ausführungsform der Erfindung fluchten die Leitwalzen für die ersten Ausgangspositionen und für die zweiten Ausgangspositionen. Dies ermöglicht dem zwischen ersten und zweiten Ausgangspositionen verschiebbaren Sensor die Erfassung einer Materialbahn mit der gleichen Messgeometrie an ersten und zweiten Ausgangspositionen.In a preferred embodiment of the invention, the guide rollers are aligned for the first starting positions and for the second starting positions. This allows the sensor displaceable between the first and second starting positions to detect a material web having the same measuring geometry at first and second starting positions.

In einer bevorzugten Ausführung ist eine Seitengestellplatte zwischen den Leitwalzen vorgesehen. Diese Seitengestellplatte ist Teil eines Seitengestells, das als Halterung für die Leitwalzen dient.In a preferred embodiment, a side frame plate is provided between the guide rollers. This side frame plate is part of a side frame that serves as a holder for the guide rolls are used.

Dieses Seitengestell weist vorzugsweise eine Öffnung auf, durch welche der Sensor zwischen den ersten und zweiten Ausgangspositionen verschoben werden kann.This side frame preferably has an opening through which the sensor can be displaced between the first and second home positions.

Vorteilhafterweise wird der Sensor entlang der Leitwalzen verschoben, er kann aber auch quer zu einer freien Materialbahn verschiebbar sein.Advantageously, the sensor is displaced along the guide rollers, but it can also be displaceable transversely to a free material web.

In einer bevorzugten Ausführung der Vorrichtung ist den Eingangspositionen eine Vorrichtung zum Zerschneiden einer ursprünglichen Materialbahn in die Materialbahnen vorgeschaltet. Eine solche Anordnung findet beispielsweise bei doppelbreiten Zeitungsmaschinen ihre Anwendung.In a preferred embodiment of the device, the input positions are preceded by a device for cutting an original material web into the material webs. Such an arrangement is used for example in double-width newspaper machines their application.

Wie bereits erwähnt, findet die Erfindung mit all ihren Ausführungsformen vor allem in Zeitungsmaschinen ihre vorteilhafte Anwendung. Daher wird bevorzugterweise jeder Ausgangsposition ein Falztrichter zugeordnetAs already mentioned, the invention with all its embodiments, especially in newspaper machines their advantageous application. Therefore, each starting position is preferably associated with a former

Die Papierbahnen 02; 03 sind z. B. längs geschnittene Teilbahnen 02; 03 einer vollen Bahn 01 und nehmen jeweils nur eine Hälfte der Leitwalze W4 ein. Die beiden von den Papierbahnen 02; 03 eingenommenen Hälften der Leitwalze W4 sollen hier als Eingangspositionen der Papierbahnen 02; 03 verstanden werden. Somit liegen zwei Papierbahnen 02; 03 mit jeweils zugeordneten Eingangspositionen vor. Die volle Bahn 01 weist beispielsweise eine Breite von vier oder sechs stehenden Druckseiten, z. B. Zeitungsseiten, insbesondere im Broadsheetformat auf. Sie wird beispielsweise in zwei bzw. drei Teilbahnen 02; 03 längs geschnitten, welche dann teilbahnbreit, z. B. zwei Druckseiten breit, sind. Unter zu einander seitlich versetzten Laufwegen ist im folgenden besonders der Versatz um zumindest eine Druckseitenbreite, insbesondere um zwei Druckseitenbreiten, z. B. mindestens eine halbe oder drittel ganze Bahn 01 zu verstehen.The paper webs 02; 03 are z. B. longitudinally cut partial webs 02; 03 a full web 01 and take only one half of the guide roller W4. The two of the paper webs 02; 03 occupied halves of the guide roller W4 are here as input positions of the paper webs 02; 03 be understood. Thus, there are two paper webs 02; 03 before each associated input positions. The full web 01 has, for example, a width of four or six standing printed pages, z. B. newspaper pages, especially in broadsheet format. It is for example in two or three partial webs 02; 03 cut longitudinally, which then partial web, z. B. two printed pages wide, are.

Bei der in Fig. 1 dargestellten Situation passiert die Papierbahn 03 das Wendedeck 21, um anschließend über die Leitwalze W3 in einen Falztrichter 11 oder über die Leitwalze W2 in einen Falztrichter 12 geführt zu werden.Both paper webs 02; 03 may optionally means 21 for lateral displacement, z. B. pass a reversing corner 21. In the situation shown in Fig. 1, the paper web 03 passes through the reversing edge 21 to then be guided via the guide roller W3 in a former 11 or on the guide roller W2 in a former 12.

Papierbahn 02 wird über verschiedene Leitwalzen 04 zu der Leitwalze W1 und anschließend in einen Falztrichter 09 geführt.Paper web 02 is guided via different guide rollers 04 to the guide roller W1 and then into a former 09.

Bei der Leitwalze W1 ist ein Sensor 08 angebracht, wobei die Papierbahn 02 zwischen der Leitwalze W1 und dem Sensor 08 hindurch geführt wird. Mit Hilfe des Sensors 08 kann eine Lage der Papierbahn 02 in Transportrichtung erfasst werden. Hierbei wird die Lage des Druckbildes oder einer auf die Papierbahn 02; 03 aufgebrachte Marke erfasst, d. h. das sog. Schnittregister mit einer Soll-Lage verglichen. Bei Abweichung erfährt die Papierbahn 02; 03 mittels einer Registereinrichtung 05, z. B. einer Registerwalze 05, einen entsprechenden Versatz bezüglich ihrer Transportrichtung. Alternativ können auch die das Druckbild auf die Papierbahn 02; 03 aufbringenden Druckwerke eine entsprechenden Änderung in der Drehwinkellage erfahren. Entsprechend ist ein Sensor 06 bei der Leitwalze W2 und ein Sensor 07 bei der Leitwalze W3 vorgesehen.In the guide roller W1, a sensor 08 is mounted, wherein the paper web 02 is guided between the guide roller W1 and the sensor 08 therethrough. With the aid of the sensor 08, a position of the paper web 02 in the transport direction can be detected. Here, the position of the printed image or on the paper web 02; 03 applied trademark, d. H. the so-called cut register compared with a desired position. In deviation, the paper web undergoes 02; 03 by means of a register device 05, z. B. a registration roller 05, a corresponding offset with respect to their transport direction. Alternatively, the print image on the paper web 02; 03 applying printing units undergo a corresponding change in the angular position. Accordingly, a sensor 06 is provided at the guide roller W2 and a sensor 07 at the guide roller W3.

Die bei den Leitwalzen W1; W2; W3 angebrachten Sensoren 06; 07; 08 sind über die Länge der Leitwalzen W1; W2; W3 verschiebbar. Für jede Leitwalze W1, W2; W3 wird jeweils ein Sensor 06, 07; 08 benötigt.The at the guide rollers W1; W2; W3 mounted sensors 06; 07; 08 are over the length of the guide rollers W1; W2; W3 displaceable. For each guide roll W1, W2; W3 is a sensor 06, 07; 08 needed.

In Fig. 2 ist die relative Anordnung der Leitwalzen W1; W2; W3 zueinander in Draufsicht gezeigt. Auf den doppelt breiten Leitwalzen W1; W2 sind Abschnitte 14; 16; 17; 18 eingezeichnet, über die die Papierbahnen 02; 03 beim Austritt aus der Vorrichtung laufen können. Dabei verlassen Papierbahnen 02; 03, die über den Abschnitt 14 auf der Leitwalze W1 oder den Abschnitt 17 auf der Leitwalze W2 laufen, die Vorrichtung auf einer Ausgangsposition A2 in Richtung des Falztrichters 12, während Papierbahnen 02; 03, die über den Abschnitt 16 auf der Leitwalze W1 oder den Abschnitt 18 auf der Leitwalze W2 laufen, die Vorrichtung auf einer Ausgangsposition A3 in Richtung des Falztrichters 09 verlassen. Die einfach breite Leitwalze W3 hat nur einen Abschnitt 13, entsprechend einer zum Falztrichter 11 führenden Ausgangsposition A1.In Fig. 2, the relative arrangement of the guide rollers W1; W2; W3 shown to each other in plan view. On the double wide guide rollers W1; W2 are sections 14; 16; 17; 18 drawn over the paper webs 02; 03 can run when exiting the device. Leaving paper webs 02; 03, which run over the section 14 on the guide roller W1 or the section 17 on the guide roller W2, the device at an initial position A2 in the direction of the former 12, while paper webs 02; 03, which run over the section 16 on the guide roller W1 or the section 18 on the guide roller W2, leave the device at an initial position A3 in the direction of the former 09. The simply wide guide roller W3 has only one section 13, corresponding to a leading to the former 11 home position A1.

Ausgangsposition A1 unterscheidet sich dahingehend von den anderen Ausgangspositionen A2; A3, dass ihr eine der Papierbahnen 02; 03 in der Regel nur nach einer seitlichen Versetzung der Papierbahn 02; 03 zugeführt werden kann.Starting position A1 differs from the other starting positions A2; A3, that you have one of the paper webs 02; 03 usually only after a lateral displacement of the paper web 02; 03 can be supplied.

Ein Seitengestell 19 dient als Halterung für die Leitwalzen W1; W2; W3. Das Seitengestell 19 verfügt z. B. über eine Seitengestellplatte 22, welche zwischen den Leitwalzen W1 und der nur durch eine seitliche Versetzung von einer der Papierbahnen 02; 03 zu erreichenden Leitwalze W3 angeordnet ist.A side frame 19 serves as a holder for the guide rollers W1; W2; W3. The side frame 19 has z. B. via a side frame plate 22, which between the guide rollers W1 and only by a lateral displacement of one of the paper webs 02; 03 to be reached guide roller W3 is arranged.

In Fig. 3 ist ein schematischer Querschnitt über eine vorteilhafter Ausführungsform der vorliegenden Erfindung dargestellt. Die Bezugszeichen entsprechen dabei den Bezugszeichen aus Fig. 1. Im Unterschied zu Fig. 1 sind die Leitwalze W3 und der Falztrichter 11 nun nicht zu sehen, da die Leitwalze W2 und die Leitwalze W3 fluchten; der Sensor 07 ist nicht mehr vorhanden. Dieser Sachverhalt ist der Fig. 4 zu entnehmen.In Fig. 3 is a schematic cross section of an advantageous embodiment of the present invention is shown. The reference numerals correspond to the reference numerals of Figure 1. In contrast to Figure 1, the guide roller W3 and the former 11 are now not visible, since the guide roller W2 and the guide roller W3 are aligned; the sensor 07 is no longer available. This situation is shown in FIG. 4.

Die Papierbahnen 02; 03 können auf verschiedenen Wegen über die Abschnitte 13; 14; 16; 17; 18 der Leitwalzen W1; W2; W3 geführt sein, um anschließend in einen der Falztrichter 11; 12; 09 zu münden. Beispielsweise können beide Papierbahnen 02; 03 auf nebeneinanderliegenden Abschnitten 14; 16 der Leitwalze W1 angeordnet sein und die Ausgangspositionen A2; A3 belegen. Oder es kann eine der Papierbahnen 02; 03 auf dem Abschnitt 14 der Leitwalze W1 angeordnet sein und die zweite Papierbahn 02; 03 auf dem Abschnitt 17 der Leitwalze W2. Dann verlassen beide Papierbahnen 02; 03 die Vorrichtung auf der Ausgangsposition A2 und münden im Falztrichter 12. Oder aber eine Papierbahn 02; 03 liegt auf Abschnitt 16 der Leitwalze W1 und die andere auf Abschnitt 18 der Leitwalze W2. Dann verlassen beide Papierbahnen die Vorrichtung auf der Ausgangsposition A3 und münden im Falztrichter 09. Schließlich kann eine der Papierbahnen 02; 03 auf der nur durch seitliche Versetzung zu erreichenden Leitwalze W3 liegen, also die Vorrichtung auf der Ausgangsposition A1 verlassen, während die andere Papierbahn 02 oder 03 die Vorrichtung auf einer der Ausgangspositionen A2 oder A3 verlässt.The paper webs 02; 03 can in various ways on the sections 13; 14; 16; 17; 18 of the guide rollers W1; W2; W3 be guided to then into one of the former 11; 12; 09 to merge. For example, both paper webs 02; 03 on adjacent sections 14; 16 of the guide roller W1 be arranged and the initial positions A2; Occupy A3. Or it may be one of the paper webs 02; 03 be arranged on the portion 14 of the guide roller W1 and the second paper web 02; 03 on the section 17 of the guide roller W2. Then leave both paper webs 02; 03 the device at the starting position A2 and open in the former 12 or else a paper web 02; 03 is on section 16 of the guide roll W1 and the other on section 18 of the guide roll W2. Then both paper webs leave the device at the starting position A3 and terminate in the former 09. Finally, one of the paper webs 02; 03 to be reached only by lateral displacement guide roller W3, so leave the device at the starting position A1, while the another paper web 02 or 03 leaves the device at one of the starting positions A2 or A3.

Wie Fig. 4 zeigt, liegen die Leitwalzen W2 und W3 nunmehr auf einer gemeinsamen Achse. Darüber hinaus ist zwischen den Leitwalzen W2 und W3 in der Seitengestellplatte 22 eine Öffnung 23 vorgesehen. Die Öffnung 23 erlaubt es, den Sensor 06 von der Leitwalze W2 durch die Seitengestellplatte 22 zur Leitwalze W3 zu verschieben. Auf diese Weise ist es möglich, mit dem Sensor 06 die Papierbahn 02; 03 zu detektieren, unabhängig davon, ob sie über die Leitwalze W2 läuft und die Ausgangspositionen A2 und/oder A3 einnimmt oder ob sie über die Leitwalze W3 läuft und die Ausgangsposition A1 einnimmt. Der zuvor benötigte Sensor 07 entfällt bei dieser Anordnung.As shown in Fig. 4, the guide rollers W2 and W3 are now on a common axis. In addition, an opening 23 is provided between the guide rollers W2 and W3 in the side frame plate 22. The opening 23 makes it possible to move the sensor 06 from the guide roller W2 through the side frame plate 22 to the guide roller W3. In this way it is possible with the sensor 06, the paper web 02; 03, regardless of whether it passes over the guide roller W2 and assumes the starting positions A2 and / or A3 or whether it passes over the guide roller W3 and assumes the starting position A1. The previously required sensor 07 is omitted in this arrangement.

Bei einer alternativen Ausführungsform der Erfindung ist statt der Leitwalzen W2 und W3 eine einzige Leitwalze aus einem Stück vorgesehen. Auf dieser Leitwalze kann eine Materialbahn über einen von drei nebeneinanderliegenden Abschnitten entsprechend den Ausgangspositionen A1; A2; A3 laufen.In an alternative embodiment of the invention, instead of the guide rollers W2 and W3, a single guide roller is provided in one piece. On this guide roller, a material web can be moved over one of three juxtaposed sections corresponding to the starting positions A1; A2; A3 running.

Für den Erfindungsgedanken ist eine fluchtende Anordnung der Leitwalzen W2 und W3 wie in der Fig. 4 gezeigt, oder wie sie sich bei einer Ersetzung dieser Leitwalzen W2 und W3 durch eine Leitwalze aus einem Stück ergibt zwar vorteilhaft, jedoch nicht unbedingt erforderlich. Beispielsweise kann sehr wohl auch eine versetzte Anordnung der Leitwalzen W2 und W3 wie in Fig. 5 gezeigt, gegeben sein. Bei entsprechend angebrachter Öffnung 23 im Seitengestell 19 oder der ggf. vorhandenen Seitengestellplatte 22 kann der Sensor 06 auch bei dieser Walzenanordnung sowohl die Anordnung einer nicht gezeigten Papierbahn 03 erfassen, die über die Leitwalze W2 läuft und die Ausgangspositionen A2 oder A3 einnehmen kann, als auch die Position einer Papierbahn 03 mit der Ausgangsposition A1, wobei er in letzterem Falle über der freien Papierbahn 03 angeordnet ist und quer zur freien Papierbahn 03 verschiebbar ist. Unter freier Papierbahn 03 ist zu verstehen, dass der Sensor 06 zu einer der entsprechenden Ausgangspositionen A1; A2; A3 zugeordneten nächsten Leitwalze W1; W2; W3 beabstandet ist.For the inventive idea is an alignment of the guide rollers W2 and W3 as shown in FIG. 4, or as it results in a replacement of these guide rollers W2 and W3 by a guide roller in one piece, although advantageous, but not essential. For example, an offset arrangement of the guide rollers W2 and W3 can very well be provided as shown in FIG. In accordance with the appropriate opening 23 in the side frame 19 or the optionally present side frame plate 22, the sensor 06 can detect both the arrangement of a paper web 03, not shown, which runs over the guide roller W2 and the initial positions A2 or A3 can occupy also in this roller arrangement, as well the position of a paper web 03 with the starting position A1, wherein it is arranged in the latter case on the free paper web 03 and transversely to the free paper web 03 is displaceable. Under free paper web 03 is to be understood that the sensor 06 to one of the corresponding Starting positions A1; A2; A3 associated next guide roller W1; W2; W3 is spaced.

Analog kann er auch zur Erfassung der Lage einer Papierbahn 02; 03 auf den Ausgangspositionen A2 und A3 über der freien Papierbahn 02; 03 angeordnet sein. Entsprechendes gilt auch für die anderen Sensoren 06; 08. Insofern bleibt der Erfindungsgedanke nicht auf das gezeigte Ausführungsbeispiel beschränkt.Analog he can also for detecting the position of a paper web 02; 03 on the starting positions A2 and A3 over the free paper web 02; 03 be arranged. The same applies to the other sensors 06; 08. In this respect, the inventive idea is not limited to the embodiment shown.

Die gezeigte Vorrichtung wird bevorzugt als Teil einer doppelbreiten Druckmaschine, z. B. Zeitungsmaschine eingesetzt. Solche Maschinen bedrucken eine ursprüngliche Papierbahn, die die vierfache Breite einer normalen Zeitungsseite aufweist. Diese ursprüngliche Papierbahn wird bei der Leitwalze W4 von einer in den Zeichnungen nicht näher dargestellten Schneidevorrichtung in die zwei Papierbahnen 02 und 03 aufgeschnitten, die jeweils die Breite zweier Zeitungsseiten haben. Die Papierbahnen 02 und 03 können anschließend auf getrennten Wegen durch die Vorrichtung geführt werden.The apparatus shown is preferred as part of a double width printing machine, e.g. B. newspaper machine used. Such machines print on an original paper web that is four times the width of a regular newspaper page. This original paper web is cut at the guide roller W4 of a cutting device not shown in the drawings in the two paper webs 02 and 03, each having the width of two newspaper pages. The paper webs 02 and 03 can then be guided through the device in separate ways.

In Weiterbildung kann mittels der Vorrichtung auch eine Lage quer zur Transportrichtung der Materialbahn 02; 03 ermittelt werden, indem der Sensor 06; 07; 08 als Sensor 06; 07; 08 zur Bahnkantenabtastung, z. B. Lichtschranke, Reflexion, etc. ausgeführt ist.In development, by means of the device also a position transverse to the transport direction of the web 02; 03 can be determined by the sensor 06; 07; 08 as a sensor 06; 07; 08 for web edge scanning, z. B. light barrier, reflection, etc. is executed.

Auch ist die Vorrichtung geeignet für Druckmaschinen dreifacher Breite, d. h. mit Druckwerken, welche zum Druck von sechs nebeneinander angeordneten stehenden Druckseiten (z. B. Zeitungsseiten) geeignet sind. Hierbei sind an Stelle der zwei Falztrichter 09; 12 drei Falztrichter und zusätzlich der Falztrichter 11 angeordnet. Die Leitwalzen W1; W2 reichen dann über sechs Zeitungsseiten, wobei z. B. einer der Sensoren 06; 08 bis über die außen liegende Materialbahn 03 verschoben werden kann.Also, the device is suitable for printing machines three times the width, ie with printing units, which are suitable for the printing of six juxtaposed standing printed pages (eg newspaper pages). Here are in place of the two formers 09; 12 three formers and additionally the former 11 arranged. The guide rolls W1; W2 then pass over six newspaper pages, with z. B. one of the sensors 06; 08 can be moved to over the outer material web 03.
