Definitions
- the present invention relates to a device for redirecting signatures in a web-fed rotary printing press, e.g. B. in a folder of the printing press, after the preamble of claim 1.
- Conventional web-fed rotary printing machines usually include stationary in the Printers arranged printing units. After passing through the printing units, a web is created guided through folding and cutting units, in which the web is folded and lengthways and crosswise is cut so that printed products e.g. in the form of signatures, which are further processed into newspapers, magazines or similar.

- the printing press can be designed so that the Signatures evenly spread over several by using one deflection device Paddle wheels or other delivery devices are distributed.
- Known Deflection devices have the disadvantage that they are on the web and by this cut signatures leave unwanted pressure marks and not along the Allow the signature to be positively guided, so that the risk of further damage to the web and the occurrence of paper jams in the Printing press exists.
- FIG. 1A and 1B show a known deflection device with a rotatable wedge 108, by means of its signatures on one side of the wedge or the other side of the wedge be directed.
- the wedge 108 is in a manner in a signature flow path 101 arranged that a tip of the wedge 108 is directed towards the incoming signature stream is. Between successive ones running along the signature current path There is a space between signatures. In each space the wedge 108 can do so be rotated so that it directs the following signature in a different direction.
- Such Construction typically includes a nip 102 which is one of a first and upstream of the second cutting cylinder 105, 107 formed cutting device 104, and a roller gap 106 arranged downstream of the cutting device 104 Roll nip 106 emerging signatures are from the wedge 108 towards one of the 1A or 112, or one of the two in FIG. 1B shown conveyors 114, 116 steered.
- Such a deflection device has several disadvantages.
- the web or the signatures are not exact and free of interference be passed through the printing press, so that a paper jam forms and the Signatures misaligned, wrinkled, torn or otherwise damaged become.
- EP-A 0 436 404 describes a transport device for sheets of paper in one Laser printer or a copier, in which the sheets of paper pass through a rotation axis swiveling pair of rollers are guided in different transport paths.
- the signatures passing between the deflection cylinders are not fixed by the Curved surfaces are gripped, they will be on a route whose length is at least corresponds to the diameter of one of the deflecting cylinders, not positively guided while they run between the deflection cylinders.
- No. 4,729,282 describes a deflection device with a stationary wedge, the tip of which is directed in the direction of signature, and two deflection rollers, which together one Form the nip and each have an eccentric axis of rotation.
- a deflection device with a stationary wedge, the tip of which is directed in the direction of signature, and two deflection rollers, which together one Form the nip and each have an eccentric axis of rotation.
- the used wedge the distance that the signatures cover without forced guidance, lengthened and increased the risk of pressure sores.
- US 5,538,242 describes a signature deflection device with two along one Signature trajectory offset cylinders.
- the device comprises tapes or Belts, which are essentially along the trajectory up to the cylinders, then partially around the cylinders and in different directions away from the cylinders to run.
- the signatures that are moved along the path towards the cylinders are between the tapes are gripped and released when the tapes are around the cylinder and thus run in different directions.
- the signatures are forced into the described device not maintained along the entire trajectory.
- the signatures are transported by being clamped between the tapes.
- forced guidance by belts is not as reliable as by cylinders, which firmly grasp the signatures.
- the bands also add complexity to the Device increases, and a difference in speed between the belts may increase damage the signatures and increases the risk of paper jams in the Press.
- Due to the staggered arrangement described in US 5,538,242 Cylinders are also the signatures on the route along the trajectory between the cylinders are only guided on one side. This means that the signatures at least on the Distance along the trajectory between the deflection cylinders and from the second Deflection cylinder and a receiving device, for. B. a paddle wheel or one another belt transport device can not be positively guided. The lack of one Forced guidance along the transport track can damage the track and the Signatures and lead to a paper jam.

- the deflection device described in this document comprises two rotating arrangements, which each comprise at least two rollers. If the arrangements are on top of each other are rotated in a coordinated manner, the outer edges of the rotating arrangements form overlapping bow.
- the described device has some disadvantages. So must the rotational movement of the two arrangements z. B. be carefully coordinated to the Change the exit angle of the signatures from the nip. This vote requires a relatively complex switch / control device that is also strong enough must be to rotate the assemblies at a speed that the Corresponds to the speed of the signatures between the arrangements.
- the in Deflection devices described in US Pat. No. 5,702,100 also use belts, which results in poor guidance of the web and the signatures, what in turn can damage the signatures and lead to paper jams.

- the Deflection device ensures a maximum using tapes Forced management of the signatures during the redirection process.
- two cylinders form one Cylinder gap through which signatures are passed.
- the axis of rotation is one of the cylinders stationary, while the axis of rotation of the other cylinder is movable along an arc line is, so that the exit angle of the cylinder gap formed by the two cylinders is changeable, the distance between the axes of rotation of the two cylinders remaining constant.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Umlenken von Signaturen in einer Rollenrotationsdruckmaschine, z. B. in einem Falzwerk der Druckmaschine, nach dem Oberbegriff von Anspruch 1.The present invention relates to a device for redirecting signatures in a web-fed rotary printing press, e.g. B. in a folder of the printing press, after the preamble of claim 1.
Herkömmliche Rollenrotationsdruckmaschinen umfassen in der Regel ortsfest in der Druckerei angeordnete Druckwerke. Nach Durchlaufen der Druckwerke wird eine Bahn durch Falz- und Schneidwerke geführt, in denen die Bahn gefalzt und längs sowie quer geschnitten wird, so daß Druckprodukte z.B. in der Form von Signaturen entstehen, welche zu Zeitungen, Zeitschriften o. ä. weiterverarbeitet werden. Die Bahn wird in Signaturen geschnitten, welche in der Regel zu einem Schaufelrad oder zu einer anderen Auslegevorrichtung befördert werden, mittels derer sie anschließend z. B. auf einem Förderband abgelegt werden. Die Druckmaschine kann so konstruiert sein, daß die Signaturen durch den Einsatz einer Umlenkvorrichtung gleichmäßig auf mehrere Schaufelräder oder sonstige Auslegevorrichtungen verteilt werden. Bekannte Umlenkvorrichtungen haben den Nachteil, daß sie auf der Bahn und den von dieser geschnittenen Signaturen unerwünschte Druckstellen hinterlassen und nicht entlang dem gesamten Transportweg der Signatur eine Zwangsführung derselben ermöglichen, so daß die Gefahr weiterer Beschädigung der Bahn und der Entstehung von Papierstaus in der Druckmaschine besteht.Conventional web-fed rotary printing machines usually include stationary in the Printers arranged printing units. After passing through the printing units, a web is created guided through folding and cutting units, in which the web is folded and lengthways and crosswise is cut so that printed products e.g. in the form of signatures, which are further processed into newspapers, magazines or similar. The train is in Signatures cut, which usually go to one paddle wheel or to another Delivery device are transported, by means of which they are then z. B. on one Conveyor belt are put down. The printing press can be designed so that the Signatures evenly spread over several by using one deflection device Paddle wheels or other delivery devices are distributed. Known Deflection devices have the disadvantage that they are on the web and by this cut signatures leave unwanted pressure marks and not along the Allow the signature to be positively guided, so that the risk of further damage to the web and the occurrence of paper jams in the Printing press exists.
Fig. 1A und 1B zeigen eine bekannte Umlenkvorrichtung mit einem drehbaren Keil 108,
mittels dessen Signaturen auf die eine Seite des Keils oder die andere Seite des Keils
gelenkt werden. Der Keil 108 ist in einer Weise in einer Signaturenstrombahn 101
angeordnet, daß eine Spitze des Keils 108 auf den einlaufenden Signaturenstrom gerichtet
ist. Zwischen aufeinanderfolgenden, entlang der Signaturenstrombahn laufenden
Signaturen besteht ein Zwischenraum. In jedem Zwischenraum kann der Keil 108 so
gedreht werden, daß er die folgende Signatur in eine andere Richtung lenkt. Eine derartige
Konstruktion umfaßt in der Regel einen Walzenspalt 102, der einer aus einem ersten und
zweiten Schneidezylinder 105, 107 gebildeten Schneidevorrichtung 104 vorgeordnet ist,
sowie einen der Schneidevorrichtung 104 nachgeordneten Walzenspalt 106. Aus dem
Walzenspalt 106 austretende Signaturen werden von dem Keil 108 in Richtung eines der
beiden in Fig. 1A gezeigten Schaufelräder 110, 112 oder einer der beiden in Fig. 1B
gezeigten Förderbahnen 114, 116 gelenkt.1A and 1B show a known deflection device with a
Eine derartige Umlenkvorrichtung weist mehrere Nachteile auf. Durch den bewegbaren Keil kann es z.B. zur Bildung von Druckstellen auf den Signaturen und zur Entstehung von Papierstaus in der Druckmaschine kommen. Ebenso wird durch den Keil die Strecke auf der Signaturentransportbahn verlängert, auf der die Signaturen nicht zwangsgeführt werden, da entlang den Keilseiten keine Zwangsführung der Signaturen besteht. Dadurch entsteht ein erhöhtes Risiko, daß die Bahn oder die Signaturen nicht exakt und störungsfrei durch die Druckmaschine geführt werden, so daß sich ein Papierstau bildet und die Signaturen falsch ausgerichtet, geknautscht, eingerissen oder auf andere Art beschädigt werden.Such a deflection device has several disadvantages. Through the movable Wedge it can e.g. for the formation of pressure points on the signatures and for the creation come from paper jams in the press. Likewise, the route becomes through the wedge extended on the signature transport path on which the signatures are not positively guided because there is no compulsory guidance of the signatures along the wedge sides. Thereby there is an increased risk that the web or the signatures are not exact and free of interference be passed through the printing press, so that a paper jam forms and the Signatures misaligned, wrinkled, torn or otherwise damaged become.
Andere Umlenkvorrichtungen weisen ähnliche Nachteile auf. US 4,373,713 beschreibt z. B. eine in einem Signaturenstrom angeordnete Bogen-Umlenkvorrichtung, welche ein Paar bewegbare, an den Signaturenstrom angrenzende Umlenkzylinder umfaßt.Other deflection devices have similar disadvantages. US 4,373,713 describes z. B. a arranged in a stream of signatures deflector, which a Includes a pair of movable deflection cylinders adjacent to the signature stream.
EP-A 0 436 404 beschreibt eine Transporteinrichtung für Papierbögen in einem Laserdrucker oder einem Kopierer, bei dem die Papierbögen durch ein um eine Drehachse schwenkbares Walzenpaar in unterschiedliche Transportpfade geleitet werden.EP-A 0 436 404 describes a transport device for sheets of paper in one Laser printer or a copier, in which the sheets of paper pass through a rotation axis swiveling pair of rollers are guided in different transport paths.
Bei der in der US 4,373,713 beschriebenen Vorrichtung besteht z. B. die Notwendigkeit, zur Minimierung der Druckstellenbildung und zur Gewährleistung eines gleichmäßigen Signaturenflusses durch die Umlenkvorrichtung die Oberflächengeschwindigkeiten der beiden Umlenkzylinder der Signaturengeschwindigkeit anzupassen. Für jede Signaturengröße werden andere Umlenkzylinder benötigt, und der Umlenkungsweg ist abhängig von der Form der auf der Umlenkzylinderoberfläche geformten Kurvenflächen sowie von den in der Regel nicht veränderbaren Radien der Umlenkzylinder. Da die zwischen den Umlenkzylindern hindurchlaufenden Signaturen nicht fest von den Kurvenflächen ergriffen werden, werden sie auf einer Strecke, deren Länge mindestens dem Durchmesser eines der Umlenkzylinder entspricht, nicht zwangsgeführt, während sie zwischen den Umlenkzylindern hindurchlaufen.In the device described in US 4,373,713 z. B. the need to minimize the formation of pressure points and to ensure an even Signature flow through the deflector, the surface speeds of the adapt both deflection cylinders to the signature speed. For every Signature size, other deflection cylinders are required, and the deflection path is depending on the shape of the curved surfaces formed on the surface of the deflecting cylinder as well as the radii of the deflecting cylinders, which as a rule cannot be changed. Since the signatures passing between the deflection cylinders are not fixed by the Curved surfaces are gripped, they will be on a route whose length is at least corresponds to the diameter of one of the deflecting cylinders, not positively guided while they run between the deflection cylinders.
US 4,729,282 beschreibt eine Umlenkvorrichtung mit einem ortsfesten Keil, dessen Spitze in Signaturlaufrichtung gerichtet ist, und zwei Umlenkwalzen, welche zusammen einen Walzenspalt bilden und jeweils eine exzentrische Drehachse haben. Bei der in der US 4,729,282 beschriebenen Vorrichtung besteht die Notwendigkeit einer sorgfältigen Synchronisierung der Drehbewegung der zwei Umlenkwalzen. Ferner wird durch den eingesetzten Keil die Strecke, welche die Signaturen ohne Zwangsführung zurücklegen, verlängert und die Gefahr der Druckstellenbildung erhöht.No. 4,729,282 describes a deflection device with a stationary wedge, the tip of which is directed in the direction of signature, and two deflection rollers, which together one Form the nip and each have an eccentric axis of rotation. At the in the US 4,729,282 device there is a need for careful Synchronization of the rotary movement of the two deflection rollers. Furthermore, by the used wedge the distance that the signatures cover without forced guidance, lengthened and increased the risk of pressure sores.
US 5,538,242 beschreibt eine Signatur-Umlenkvorrichtung mit zwei entlang einer Signaturenbewegungsbahn versetzten Zylindern. Die Vorrichtung umfaßt Bänder oder Gurte, welche im wesentlichen entlang der Bewegungsbahn bis zu den Zylindern, dann teilweise um die Zylinder herum und in verschiedene Richtungen von den Zylindern weg laufen. Die entlang der Bahn auf die Zylinder zu bewegten Signaturen werden zwischen den Bändern ergriffen und losgelassen, wenn die Bänder um die Zylinder herum und somit in verschiedene Richtungen laufen. Die Zwangsführung der Signaturen wird in der beschriebenen Vorrichtung nicht entlang der gesamten Bewegungsbahn aufrechterhalten. Die Signaturen werden transportiert, indem sie zwischen die Bänder geklemmt werden. Eine Zwangsführung durch Bänder ist jedoch nicht so zuverlässig wie durch Zylinder, welche die Signaturen fest ergreifen. Durch die Bänder wird außerdem die Komplexität der Vorrichtung erhöht, und ein Geschwindigkeitsunterschied zwischen den Bändern kann zu einer Beschädigung der Signaturen führen und erhöht die Gefahr eines Papierstaus in der Druckmaschine. Durch die in US 5,538,242 beschriebene versetzte Anordnung der Zylinder sind die Signaturen ferner auf der Strecke entlang der Bewegungsbahn zwischen den Zylindern nur einseitig geführt. Dies bedeutet, daß die Signaturen mindestens auf der Strecke entlang der Bewegungsbahn zwischen den Umlenkzylindern und von dem zweiten Umlenkzylinder und einer Aufnahmevorrichtung, z. B. einem Schaufelrad oder einer weiteren Bandtransportvorrichtung nicht zwangsgeführt werden. Das Fehlen einer Zwangsführung entlang der Transportbahn kann zu einer Beschädigung der Bahn und der Signaturen und zu einem Papierstau führen.US 5,538,242 describes a signature deflection device with two along one Signature trajectory offset cylinders. The device comprises tapes or Belts, which are essentially along the trajectory up to the cylinders, then partially around the cylinders and in different directions away from the cylinders to run. The signatures that are moved along the path towards the cylinders are between the tapes are gripped and released when the tapes are around the cylinder and thus run in different directions. The signatures are forced into the described device not maintained along the entire trajectory. The signatures are transported by being clamped between the tapes. However, forced guidance by belts is not as reliable as by cylinders, which firmly grasp the signatures. The bands also add complexity to the Device increases, and a difference in speed between the belts may increase damage the signatures and increases the risk of paper jams in the Press. Due to the staggered arrangement described in US 5,538,242 Cylinders are also the signatures on the route along the trajectory between the cylinders are only guided on one side. This means that the signatures at least on the Distance along the trajectory between the deflection cylinders and from the second Deflection cylinder and a receiving device, for. B. a paddle wheel or one another belt transport device can not be positively guided. The lack of one Forced guidance along the transport track can damage the track and the Signatures and lead to a paper jam.
US 5,702,100 beschreibt eine Umlenkvorrichtung für Signaturen in einem Falzwerk einer Druckmaschine. Durch einen Satz Hochgeschwindigkeits-Bänder werden Signaturen zu einer Umlenkvorrichtung transportiert, welche die Signaturen wahlweise umlenkt. Die in dieser Schrift beschriebene Umlenkvorrichtung umfaßt zwei rotierende Anordnungen, welche jeweils mindestens zwei Walzen umfassen. Wenn die Anordnungen aufeinander abgestimmt gedreht werden, bilden die Außenkanten der rotierenden Anordnungen sich überschneidende Bogen. Die beschriebene Vorrichtung weist einige Nachteile auf. So muß die Drehbewegung der beiden Anordnungen z. B. sorgfältig abgestimmt sein, um den Austrittswinkel der Signaturen aus dem Walzenspalt zu verändern. Diese Abstimmung erfordert eine relativ komplexe Schalter/Steuerungsvorrichtung, die zudem stark genug sein muß, um die Anordnungen mit einer Geschwindigkeit zu drehen, die der Geschwindigkeit der Signaturen zwischen den Anordnungen entspricht. In den in US 5,702,100 beschriebenen Umlenkvorrichtungen werden ferner Bänder eingesetzt, woraus sich eine nur mangelhafte Zwangsführung der Bahn und der Signaturen ergibt, was wiederum zu einer Beschädigung der Signaturen und zu Papierstaus führen kann.US 5,702,100 describes a deflection device for signatures in a folder Press. Signatures become through a set of high-speed tapes transported a deflection device, which optionally deflects the signatures. In the deflection device described in this document comprises two rotating arrangements, which each comprise at least two rollers. If the arrangements are on top of each other are rotated in a coordinated manner, the outer edges of the rotating arrangements form overlapping bow. The described device has some disadvantages. So must the rotational movement of the two arrangements z. B. be carefully coordinated to the Change the exit angle of the signatures from the nip. This vote requires a relatively complex switch / control device that is also strong enough must be to rotate the assemblies at a speed that the Corresponds to the speed of the signatures between the arrangements. In the in Deflection devices described in US Pat. No. 5,702,100 also use belts, which results in poor guidance of the web and the signatures, what in turn can damage the signatures and lead to paper jams.
EP 0 297 282 B1 beschreibt Schneidezylinder, welche als Einheit zusammen bezüglich einer zwischen den Schneidezylindern verlaufenden Bahntransportbahn seitlich verschiebbar sind. Fig. 1 und 2 dieser Schrift zeigen geschnittene Signaturen, die auf der einen oder der anderen Seite eines Keils zwischen den Schneidezylindern austreten und zu einer von zwei aus Bändern gebildeten Aufnahmevorrichtungen geführt werden. Der Einsatz des Keils und der zugeordneten Bänder hat jedoch verschiedene Nachteile, u. a. die Bildung von Druckstellen auf den Signaturen und eine mangelhafte Zwangsführung.EP 0 297 282 B1 describes cutting cylinders which together as a unit a web transport path running between the cutting cylinders on the side are movable. 1 and 2 of this document show cut signatures on the one side or the other of a wedge between the cutting cylinders emerge and close one of two receptacles formed from strips can be guided. The However, using the wedge and the associated bands has several disadvantages, u. a. the Formation of pressure points on the signatures and poor guidance.

Die Drehachse eines der Zylinder ist ortsfest, während die Drehachse des anderen Zylinders entlang einer Bogenlinie bewegbar ist, so daß der Austrittswinkel des von den beiden Zylindern geformten Zylinderspalts veränderbar ist, wobei der Abstand der Drehachsen der beiden Zylinder konstant bleibt.According to a first embodiment of the invention, two cylinders form one Cylinder gap through which signatures are passed. The axis of rotation is one of the cylinders stationary, while the axis of rotation of the other cylinder is movable along an arc line is, so that the exit angle of the cylinder gap formed by the two cylinders is changeable, the distance between the axes of rotation of the two cylinders remaining constant.
In einer zweiten Ausführungsform der Erfindung sind die Zylinder über ein Joch miteinander verbunden. Der Austrittswinkel des Zylinderspalts wird vorzugsweise dadurch verändert, daß das Joch um eine parallel zu den Drehachsen der Zylinder und von beiden Drehachsen gleich beabstandet angeordnete Drehachse gedreht wird.In a second embodiment of the invention, the cylinders are over a yoke connected with each other. The exit angle of the cylinder gap is preferably thereby changed that the yoke by one parallel to the axes of rotation of the cylinders and by both Rotation axes is rotated equally spaced rotation axis.
Demgemäß kann die Umlenkung einer den Zylinderspalt passierenden Signatur durch Drehen des Zylinderspalts um entweder a) eine Drehachse eines der Zylinder oder b) die Mittellinie des Zylinderspalts oder eine nahe der Mittellinie angeordnete Drehachse erfolgen, um den Zylinderspalt in eine bestimmte Richtung auszurichten.Accordingly, the redirection of a signature passing through the cylinder gap by rotating the cylinder gap around either a) an axis of rotation of one of the cylinders or b) the center line of the cylinder gap or an axis of rotation arranged near the center line done to align the cylinder gap in a certain direction.
Weitere Ausführungsformen der vorliegenden Erfindung betreffen eine Umlenkvorrichtung, welche einzeln oder in Kombination mit mehreren Aufnahmevorrichtungen in Rollenrotationsdruckmaschinen eingesetzt werden kann und einen von einem ersten und einem zweiten Zylinder gebildeten Zylinderspalt und eine Schwenkvorrichtung zum Verändern der Transportrichtung des Zylinderspalts durch Drehen des Zylinderspalts entweder um eine Drehachse eines der beiden Zylinder oder um eine Mittellinie des Zylinderspalts umfaßt.

Wie in Fig. 2A gezeigt ist, bilden gemäß einer nicht erfindungsgemäßen Ausführungsform
eine vorlaufende Walze 200 und eine nachlaufende Walze 210 eine
Walzenspalt 250, durch den eine Signatur 240 geführt wird. Die Walzen 200 und 210
werden vorzugsweise durch einen gemeinsamen Motor mit im wesentlichen der gleichen
Drehzahl, beispielsweise mit der Geschwindigkeit der Druckmaschine oder des
Falzapparates angetrieben. Zur Veränderung der Austrittsrichtung der Signatur 240 aus
dem Walzenspalt 250 kann eine Schwenkvorrichtung vorgesehen sein, mittels derer eine
Achse 201 der vorlaufenden Walze 200 entlang einer Bogenlinie 203 um eine
Drehachse 211 der nachlaufenden Walze 210 in einer Weise geschwenkt werden kann, daß
der Abstand zwischen den Drehachsen 201 und 211 der vorlaufenden Walze 200 und der
nachlaufenden Walze 210 konstant bleibt. Auf diese Weise kann der Transportweg
wechselweise auf eine Vielzahl von Aufnahmevorrichtungen, wie z. B. Schaufelräder oder
Transportbänder etc. ausgerichtet werden. Das heißt, wenn die vorlaufende Walze 200
vorwärts bewegt wird, so wird der Walzenspalt um die Achse 201 gedreht, so daß, wie in
Fig. 2A gezeigt ist, die Signatur 240 unterhalb des Keils 220 geführt wird. Wird die
vorlaufende Walze 200 rückwärts bewegt, so wird, wie in Fig. 2B gezeigt ist, die
Signatur 240 oberhalb des Keils 220 geführt. In einer alternativen Ausführungsform kann
der Keil 220 auch entfallen und jede der beiden Walzen kann als die bewegbare,
vorlaufende Walze ausgebildet sein. Die vorlaufende Walze kann mittels bekannter
Verfahren und Vorrichtungen entlang der Bogenlinie bewegt werden, z. B. mittels eines
Exzenters, einer Exzenterrolle und eines Hebels, der die Exzenterrolle mit der
Drehachse 201 verbindet, wie es im folgenden in Bezug auf die in Fig. 3 gezeigte
Ausführungsform beschrieben ist.As shown in FIG. 2A, form according to an embodiment not according to the invention
a leading
Fig. 3 zeigt eine beispielhafte Ausführungsform der Erfindung, in der zwei mit im
wesentlichen der gleichen Drehgeschwindigkeit angetriebenen Zylinder 300 und 310 einen
Zylinderspalt 350 bilden, durch den eine Signatur 240 hindurchgeführt wird. Die
Zylinder 300 und 310 sind an einem Joch 351 in der Weise befestigt, daß der Abstand
zwischen den Drehachsen 301 und 311 der Zylinder 300 und 310 im wesentlichen gleich
bleibt (d. h., z.B. so weit variabel ist, daß er an verschiedene Signaturendicken angepaßt
werden kann). Das Joch 351 kann so angeordnet sein, daß bei Drehung desselben die
Achsen 301 und 311 der Zylinder 300 und 310 vorzugsweise entlang den Bogenlinien 382
eines Kreises bewegt werden, dessen Mittelpunkt von den beiden Achsen 301 und 311
gleich weit entfernt ist und auf einer Geraden liegt, welche beide Drehachsen 301 und 311
schneidet.Fig. 3 shows an exemplary embodiment of the invention, in which two with in
substantially the same rotational speed driven
Wie in Fig. 3 gezeigt ist, ist der Mittelpunkt oder Schwenkpunkt 380 vorzugsweise der
Mittelpunkt des von den Zylindern 300 und 310 gebildeten Zylinderspalts 350. Es sind
Bänder 305 vorgesehen, welche die Signatur zu dem Zylinderspalt führen. In Fig. 3 sind
die Zylinder 300 und 310 so positioniert, daß eine Signatur 240 aus dem Zylinderspalt 350
in Richtung eines weiteren Zylinderspalts 360 austritt, der Bänder 363 und 364 aufweisen
kann, welche die Signatur 240 aus dem Zylinderspalt 360 hinausführen. Dabei wird die
Signatur 240 zwischen den Bändern 363 und 364 gehalten, so daß die Signatur und die
Bänder eine sandwichartige Anordnung 365 bilden. Der Zylinderspalt 360 wird von zwei
Zylindern 361 und 362 gebildet. As shown in FIG. 3, the center point or
Eine Schwenkvorrichtung zum Verändern der Transportrichtung an dem Zylinderspalt
umfaßt z.B. eine am Ende eines Arms des Jochs 351 angeordnete Walze 345, welche eine
Exzenterrolle bildet, die gegen die Oberfläche eines drehbaren Exzenters oder Nockens 341
drückt. Wird der Exzenter 341 gedreht, so bewegt sich die Exzenterrolle 345 und somit das
Joch 351, so daß die Zylinder 300 und 310 entlang der Bogenlinie 382 bewegt werden und
die Austrittsrichtung des Zylinderspalts 350 und damit die Laufrichtung einer aus dem
Zylinderspalt austretenden Signatur 240 entweder auf den Zylinderspalt 360 oder den
weiteren Zylinderspalt 370 ausgerichtet wird.A swivel device for changing the transport direction at the cylinder gap
includes e.g. a
Der Zylinderspalt 370 ist vorzugsweise wie der Zylinderspalt 360 ausgebildet und wird von
Zylindern 371, 372 und Bändern 373, 374 gebildet. Die Bänder 373 und 374 ergreifen die
Signatur zwischen sich und bilden so eine sandwichartige Anordnung 375, um die
Signatur 240 von dem Zylinderspalt 370 weg zu transportieren, wenn der Zylinderspalt 350
und die Signatur 240 auf den Zylinderspalt 370 gerichtet sind.The
Die in Fig. 4 gezeigte Vorrichtung ähnelt der in Fig. 3 gezeigten Ausführungsform. In
Fig. 4 sind jedoch an dem von den Zylindern 300 und 310 gebildeten Zylinderspalt 450
keine Bänder vorgesehen. Stattdessen ist dem Zylinderspalt 450 ein weiterer, von zwei
Zylindern 491,492 und Bändern 494, 493 gebildeter Zylinderspalt 490 vorgeordnet,
mittels dessen die Signatur 240 zu dem Zylinderspalt 450 transportiert wird. In Fig. 4 ist
der Zylinderspalt 450 mit auf den unteren Zylinderspalt 370 gerichteter Signatur 240
gezeigt.The device shown in FIG. 4 is similar to the embodiment shown in FIG. 3. In

Fig. 5 zeigt eine Detailansicht einer Ausführungsform des Jochs 351. Wie in Fig. 5 gezeigt
ist, kann das Joch 351 steif und, wie es zuvor in Zusammenhang mit Fig. 3 und 4
beschrieben ist, um den Schwenkpunkt 380 schwenkbar ausgebildet sein. Zur
Positionierung der Drehachsen 301 und 311 entlang der Bogenlinie 382 können auch
andere bekannte Verfahren und Vorrichtungen eingesetzt werden. Das Joch 351 kann
ferner auch um eine der Drehachsen 301 und 311 schwenkbar ausgebildet sein und somit
auch in den in Fig. 2A und 2B gezeigten Ausführungsformen eingesetzt werden. FIG. 5 shows a detailed view of an embodiment of the
