It is a paper web guide in a web-fed rotary printing machine with a number of Paper web guide rollers are provided between printing units and hoppers of a folder. At least 2 funnels are next to each other in a common horizontal plane arranged, with at least one longitudinal cutting device for cutting a paper web into a remainder and a partial web per paper web.

Bei Zeitungen werden mehrere Ausgaben auf Rotationsdruckmaschinen gedruckt. Die Ausgaben werden in größeren oder kleineren Auflagen hergestellt, je nachdem, ob für größere oder kleinere Auslieferungsbezirke bestimmt. Daher ist es notwendig, mehrere verschiedene Rotationen einzusetzen, um die Auflage nacheinander abzudrucken.For newspapers, multiple editions are printed on rotary presses. The Issues are produced in larger or smaller editions, depending on whether for larger ones or smaller delivery districts. Therefore it is necessary to have several different ones Use rotations to print the edition one after the other.

Die Herstellung einer einzelnen Auflage lediglich auf einer Rotationsdruckmachine und zwar in Abständen nacheinander führt, zu einer längeren Herstellungszeit der Gesamtauflage. Ist die Entscheidung gefallen, eine Auflage auf zwei Rotationen zu drucken, so sind damit zwangsläufig große Investitionshöhen, die die zweite Druckmaschine betreffen, verbunden. The production of a single edition only on a rotary printing press and at intervals, one after the other, leads to a longer production time for the entire edition. If the decision is made to print an edition on two rotations, then inevitably associated with large investment amounts that affect the second printing press.

Ausgehend von den skizzierten Lösungen des Standes der Technik, liegt der Erfindung die Aufgabe zugrunde, auf einer doppelbreiten Rotation Auflagen unterschiedlicher Länge unabhängig voneinander herzustellen.Based on the outlined solutions of the prior art, the invention lies The task is based on a double-width rotation of different lengths to manufacture independently.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruches 1 gelöst.According to the invention the object is solved by the features of claim 1.

Die mit der erfindungsgemäßen Lösung einhergehenden Vorteile sind vielfältiger Natur. Die Unterteilung des rotierenden Führungselementes in unabhängig voneinander betreibbare Führungsabschnitte erlaubt einen kontinuierlichen Betrieb einer Rollenrotation zur Herstellung einer großen Auflage; andererseits kann unabhängig vom Druck der großen Auflage eine geringere Auflage produziert werden, die über einen der unabhängigen Führungsabschnitte geführt werden kann, ohne den Druck der hohen Auflage zu beeinträchtigen. Somit ist eine unabhängige gleichzeitige Produktion unterschiedlich hoher Auflagen - auf einer doppeltbreiten Zeitungsrotation - möglich. Die hohe Auflage kann abgedruckt werden, während die geringere Auflage bereits fertig gedruckt ist und auf dem verbliebenen nunmehr freien Führungsabschnitt kann ein weiterer Druckauftrag vorbereitet werden. Bei Zeitungs- und Akzidenzrotationen enthalten die Auflagen meistens durchaus identische Sektionen und unterscheiden sich nur in Inserts oder Lokalteilen. Diese können individuell in geringeren Auflagen unabhängig von einem längeren Druckauftrag an ein- und derselben Rotation zeitgleich gedruckt werden.The advantages associated with the solution according to the invention are diverse in nature. The division of the rotating guide element into independently operable Guide sections allow continuous operation of a roll rotation for manufacturing a large edition; on the other hand, regardless of the printing of the large edition a smaller edition will be produced which will be over one of the independent guide sections can be performed without affecting the pressure of the high circulation. Thus, an independent simultaneous production of differently high runs is on a double-width newspaper press - possible. The high edition can be printed while the smaller edition is already printed and on the remaining one Now a free print section can be prepared for another print job. At Newspaper and commercial presses mostly contain identical editions Sections and differ only in inserts or local parts. These can be customized in shorter runs regardless of a longer print job on one and the same Rotation can be printed at the same time.

In vorteilhafter Ausgestaltung des der Erfindung zugrundeliegenden Gedankens ist das Führungselement beispielsweise als eine Trichtereinlaufwalze ausgestaltet und oberhalb eines Falztrichters eines oder mehrere Falztrichter angeordnet. Jedem der beiden Führungsabschnitte kann ein separater Antrieb zugeordnet werden, wobei die Antriebe unabhängig voneinander angesteuert werden können.In an advantageous embodiment of the idea on which the invention is based, this is For example, the guide element is designed as a funnel inlet roller and above of a former one or more former. Each of the two guide sections A separate drive can be assigned, whereby the drives are independent can be controlled from each other.

Die eine durchgängige, rotierende Oberfläche bildenden Trichtereinlauf-walzenoberflächen sind relativ zueinander verdrehbar und können beispielsweise über einen Freilauf miteinander verbunden sein, der sowohl eine gemeinsame Drehung beider Führungswalzenabschnitte, als auch eine jeweils getrennte Drehung der Führungswalzenabschnitte in bezug aufeinander zuläßt. Eine möglichst wenig Bauraum beanspruchende Lagerung der Trichtereinlaufwalze wird dadurch erreicht, daß eine der Führungswalzenabschnitte jeweils als Lagerung für den anderen Führungswalzenabschnitt dient.The funnel inlet roller surfaces that form a continuous, rotating surface are rotatable relative to each other and can, for example, with one another via a freewheel be connected, which is both a common rotation of both guide roller sections, as well as a separate rotation of the guide roller sections with respect allows each other. Storage of the hopper inlet roller which takes up as little installation space as possible is achieved in that one of the guide roller sections each as Storage for the other guide roller section is used.

Dazu kann ein Vorsprung eines Führungswalzenabschnittes - beispielsweise ein Lager - formschlüssig in eine Ausnehmung am anderen Führungsabschnitt eingreifen. Neben einem Freilauf, einer Kupplung, einer Zapfen/Bohrung-Lagerung wäre es durchaus auch möglich, andere, die unabhängige Rotation ermöglichende Einrichtungen zwischen den Führungsabschnitten vorzusehen; beispielsweise Kugellager, Büchsenlager mit Schmierung und dergleichen mehr.For this purpose, a projection of a guide roller section - for example a bearing - engage positively in a recess on the other guide section. Besides one Freewheel, a clutch, a pin / bore bearing, it would definitely be possible, other devices that enable independent rotation between the Provide guide sections; for example ball bearings, bush bearings with lubrication and the like.

Die Falzsektionen im Überbau enthalten jeweils mehrere Längsfalzeinheiten. Mehrere der Längsfalzeinheiten können im Falzapparatüberbau nebeneinander angeordnet sein. Die Längsfalzeinheiten lassen sich beispielsweise jeweils zu zweit nebeneinanderliegend in drei Ebenen positionieren, wodurch eine sehr hohe Produktionsvielfalt bei Zeitungsrotationen erreichbar ist.The folding sections in the superstructure each contain several longitudinal folding units. Several of the Longitudinal folding units can be arranged side by side in the folder superstructure. The Longitudinal folding units can, for example, be placed side by side in pairs position three levels, resulting in a very high production variety with newspaper rotations is achievable.

Rotierende Bahnleitwalzen im Überbau, nach dem Trockner, in der Kühlwalzensektion sowie vor den Druckwerken im Eindruckwerkbereich können ebenfalls sehr vorteilhaft mit unabhängig voneinander betreibbaren Walzenabschnitten ausgestattet werden. Die Bahnführung kann so gestaltet werden, daß Teile der Bahn beim Drukken sämtliche Druckwerke durchlaufen, während andere Teile unter Umgehung einzelner Druckwerke über diese oder unter diesen hindurch geführt werden. Eine solche Flexibilität ist erforderlich, um eine hohe Investition darstellende Zeitungsrotation stets effektiv auszulasten. Durch die erfindungsgemäß vorgeschlagene Vorrichtung wird eine effektive Auslastung einer Zeitungsrotation noch erhöht.Rotating web guide rollers in the superstructure, after the dryer, in the chill roller section as well as in front of the printing units in the impression unit area can also be very advantageous equipped with independently operable roller sections become. The web guide can be designed so that parts of the web when printing go through all printing units while other parts are bypassed individual printing units are guided over or under these. A Such flexibility is required to be a high investment newspaper press always effective. Through the device proposed according to the invention effective utilization of a newspaper press is increased.

Die beispielsweise als Trichtereinlaufwalze einsetzbare Bahnführungswalze kann in Überbauten mit und ohne Längsschneideinrichtungen betrieben werden, wobei das Vorsehen von Längsschneideinrichtungen die Flexibilität und Vielseitigkeit einer Rollenrotation noch erhöht. Bevorzugt wird die geteilte Bahnführungswalze an Zeitungsrotationen eingesetzt, aber auch deren Einsatz in Akzidenzrollenrotationsdruckmaschinen ist denkbar.The web guide roller, which can be used, for example, as a funnel infeed roller, can be used in superstructures be operated with and without slitting devices, the provision of slitting machines the flexibility and versatility of a roll rotation still increased. The split web guide roller is preferably used on newspaper presses, but their use in commercial web rotary presses is also conceivable.

Anhand der Zeichnungen wird die Erfindung nachstehend erläutert.The invention is explained below with reference to the drawings.

Fig. 1 zeigt eine schematische Ansicht einer Rotation mit 2 jeweils 3 Achtertürme enthaltenden Druckgruppen mit gemeinsamem Überbau und gemeinsamem Falzapparat.Fig. 1 shows a schematic view of a rotation with 2 each containing 3 four-high towers Printing groups with a common superstructure and a common folder.

In dieser Konfiguration sind zwei Druckgruppen 1, mit jeweils 3 Achtertürmen vorgesehen, von denen die bedruckten, mehrlagigen Bahnstränge einem beiden Druckgruppen 1,6 gemeinsamen Wendestangen über Bau 2 zugeleitet werden. Im Wendestangendeck 2, welches eine Vielzahl unterschiedlich positionierter Wendestangen 2.1, die stationär oder verschieblich angeordnet sein können, aufnimmt, werden die in den Druckgruppen 1 beziehungsweise 6 unterschiedlich bedruckten Materialbahnen entsprechend der gewünschten Produktzu-sammenstellung zusammengeführt - d.h. entsprechend der unterschiedlichen Zeitungseinlagen - übereinandergelegt und anschließend in Zylinderteilen von Falzapparaten 16, 17 weiterverarbeitet.In this configuration, two pressure groups 1, each with 3 eight-high towers, are provided, of which the printed, multilayered web strands belong to two printing groups 1.6 common turning bars can be supplied via building 2. In the turning bar deck 2, which a variety of differently positioned turning bars 2.1, the stationary or can be arranged displaceably, the pressure groups 1 and 6 differently printed material webs according to the desired Product compilation merged - i.e. according to the different Newspaper inserts - one on top of the other and then in cylinder parts of folders 16, 17 processed.

In der ersten Druckgruppe 1, bestehend aus den Achtertürmen 1.1, 1.2 und 1.3, werden die Materialbahnen A, B, C und D jeweils mit unterschiedlicher Druckwerkbelegung bedruckt. Die Bahn A der Druckgruppe 1 wird im ersten Achterturm 1.1 4/1 bedruckt, d.h. eine Oberseite der Bahn A wird in den übereinanderliegend angeordneten Druckwerken nacheinander cyan, magenta, gelb und schwarz bedruckt, während die korrespondierende Unterseite im Achterturm 1.1, dessen oberstes Druckwerk schwarz bedruckt wird, bevor die Bahn A den Achterturm 1.1 verläßt. Nach Verlassen des Achterturms 1.1 läuft die 4/1 bedruckte Bahn A in den Wendestangen über Bau 2 ein.In the first printing group 1, consisting of the four-high towers 1.1, 1.2 and 1.3, the Material webs A, B, C and D are each printed with different printing unit assignments. The web A of printing group 1 is printed in the first four-high tower 1.1 4/1, i.e. a The top of the web A is successively in the printing units arranged one above the other cyan, magenta, yellow and black printed, while the corresponding underside in the aft tower 1.1, the top printing unit is printed in black before the Lane A leaves the aft tower 1.1. After leaving the four-high tower 1.1, the 4/1 printed runs Lane A in the turning bars above building 2.

Im zweiten Achterturm 1.2 der Druckgruppe 1 werden die Bahnen B und C bedruckt, jeweils mit unterschiedlicher Farbbelegung auf Ober-/ und Unterseite. Die Bahn B läuft seitlich in den zweiten Achterturm 1.2 ein und wird in den zu oberst angeordneten beiden Druckwerken des Achterturmes 1.2 beidseitig schwarz bedruckt, bevor die Bahn B den Achterturm 1.2 in Richtung des Wendestangendecks 2 wieder verläßt. Die Bahn C wird im Achterturm 1.2 4/1 bedruckt. Sie läuft oberhalb des ersten Druckwerkpaares in den Achterturm 1.2 ein, und wird um den Übertragungszylinder des unteren Druckwerkes geführt, wobei dort cyan und gelb hintereinander auf die Oberseite der Bahn C gedruck werden. Anschließend passiert die Bahn C die weiteren Druckwerke, wo sie magenta und schwarz bedruckt wird. Im dritten Druckwerk im Achtertum 1.2 wird die Bahn C auf Ober- und Unterseite schwarz bedruckt. Danach verläßt die nunmehr ebenfalls 4/1 bedruckte Bahn C den Achterturm 1.2 unterhalb des obersten Druckwerkes des Achterturmes 1.2, in welchem bereits die Materialbahn B beidseitig 1 über 1 bedruckt worden ist. In the second four-high tower 1.2 of printing group 1, the webs B and C are printed, respectively with different color assignments on top and bottom. Lane B runs to the side in the second aft tower 1.2 and is located in the top two Printing units of the aft tower 1.2 printed black on both sides before the web B the Aft tower 1.2 in the direction of the turning bar deck 2 leaves again. The web C is in Aft tower 1.2 4/1 printed. It runs into the aft tower above the first pair of printing units 1.2, and is guided around the transfer cylinder of the lower printing unit, where cyan and yellow are printed one after the other on the top of the web C. The web C then passes the other printing units, where it is magenta and black is printed. In the third printing unit in Achtertum 1.2, the web C is on top and Bottom printed in black. Then leaves the now also 4/1 printed web C. the aft tower 1.2 below the uppermost printing unit of the aft tower 1.2, in which The material web B has already been printed on both sides 1 over 1.

In der Druckgruppe 1 verbleibenden Achterturm 1.3 wird die Bahn D bei Passage aller Druckwerke 4/4 bedruckt, wobei die Bahn D streng vertikal verläuft. Die Bahn D verläßt den Achterturm 1.3 am oberen Ende, um in den Wendestangenüberbau 2 einzulaufen.In printing group 1, the four-high tower 1.3 is the path D at the passage of all Printing units 4/4 printed, the web D being strictly vertical. Lane D leaves the aft tower 1.3 at the top to enter the turning bar superstructure 2.

Der Vollständigkeit halber sei erwähnt, daß der Achterturm seinen Namen daher hat, daß in diesen 4 Druckwerken je 2 einander gegenüberliegenden Druckeinheiten angeordnet sind. Unterhalb des in Fig. 2 nur schematisch wiedergegebenen Aufbaus und der Bahnpfade der Achtertürme, sind in den Kellergeschoßen unterhalb des Fundamentes die die Bahnvorratsrollen aufnehmenden Rollenwechsler aufgenommen, die hier nicht näher dargestellt sind, durch diese werden die Achtertürme der beiden Druckgruppen 1 und 6 mit dem zu bedrukkenden Bahnvorrat versorgt.For the sake of completeness it should be mentioned that the figure of eight tower gets its name from the fact that in these 4 printing units are each arranged 2 opposing printing units. Below the structure shown only schematically in Fig. 2 and the path of the Aft towers, in the basement below the foundation, are the train supply rolls receiving reel changer, which are not shown here, through this, the four-high towers of the two printing groups 1 and 6 with the one to be printed Rail supply supplied.

Analog zu Druckgruppe 1, enthält die weitere Druckgruppe 6 drei Achtertürme 6.1, 6.2 und 6.3, in denen die Bahnen E, F, G und H bedruckt werden. Im dargestellten Ausführungsbeispiel wird die Bahn E im Achterturm 6.1 4/4 bedruckt, die Bahnen F und G im Achterturm 6.2 4/2 beziehungsweise 1/1 analog zum zweiten Achterturm 1.2 der ersten Druckgruppe 1 . Im Achterturm 6.3 wird die Bahn H 4/4 bedruckt. Da sich die Bahnführung und die Farbbelegung in der weiteren Druckgruppe 6 wie in der bereits dargestellten Druckgruppe 1 verhält, wird zur Vermeidung von Wiederholungen auf das im Zusammenhang mit Druckgruppe 1 bereits Gesagte verwiesen.Analogous to pressure group 1, the further pressure group 6 contains three four-high towers 6.1, 6.2 and 6.3, in which the webs E, F, G and H are printed. In the illustrated embodiment the web E in the aft tower 6.1 4/4 is printed, the webs F and G in the aft tower 6.2 4/2 or 1/1 analogous to the second eight-high tower 1.2 of the first pressure group 1 . The web H 4/4 is printed in the aft tower 6.3. Because the web guide and the color assignment in the further print group 6 as in the print group already shown 1 behaves, is related to avoiding repetitions already referred to with print group 1.

Die aus den Druckgruppen 1,6 herauslaufenden Bahnen A, B, C, D und E, F, G und H laufen in die Wendestangensektion 2 ein; von dort werden sie entsprechend zusammengelegt und zusammengeführt in die Falzsektion 3 eingeführt, die aus mehreren Falzeinheiten in 3 Ebenen 3.1, 3.2 und 3.3 übereinander angeordnet besteht.The webs A, B, C, D and E, F, G and H running out of the pressure groups 1.6 run into the turning bar section 2; from there they are merged accordingly and brought together in the folding section 3, which consists of several folding units in FIG. 3 Levels 3.1, 3.2 and 3.3 are arranged one above the other.

Von dort aus laufen die Bahnen A, B, C und D beziehungsweise E, F, G und H in die Zylinderteile der Falzapparate ein.From there, the paths A, B, C and D or E, F, G and H run into the cylinder parts of the folders.

In der Fig. 2 ist die erfindungsgemäße Bahneinführwalze mit unabhängig voneinander betreibbaren Bahnführungsabschnitten näher dargestellt.2, the web insertion roller according to the invention can be operated independently of one another Web guide sections shown in more detail.

In der in Fig. 1 gezeigten Falzsektion 3 befinden sich in drei übereinanderliegenden Ebenen 3.1, 3.2 bziehungsweise 3.3 paarweise nebeneinander liegende Falztrichter 8.9, über deren Trichternasen 20 die dort längs gefalzten Bahnstränge ablaufen. Die Bahnführungswalze 7 fungiert in der Darstellung gemäß Fig. 2 als geteilte Trichtereinlaufwalze 7, mit 2 unabhängig voneinander betreibbaren Walzenabschnitten 13 und 14. Die beiden Walzenabschnitte 13 beziehungsweise 14 verfügen über je einen Antrieb 11 beziehungsweise 12. Die beiden Walzenabschnitte 13 beziehungsweise 14 verfügen über je einen Antrieb 11 beziehungsweise 12. Die beiden Walzenabschnitte 13 und 14 sind so miteinander verbunden, daß ein Walzenabschnitt 13 beziehungsweise 14 den jeweils anderen Walzenabschnitt als Lagerung fungiert. Dazu kann zwischen den Walzenabschnitten 13 und 14 eine Kupplung 10 aufgenommen sein, die einen Zapfen 10.1 beziehungsweise eine Ausnehmung 10.2 enthalten, die eine formschlüssige Verbindung der beiden Walzenabschnitte 13 beziehungsweise 14 ermöglichen, ohne deren voneinander unabhängige Rotation zu behindern. Neben einer Kupplung 10 können auch Kugellager, geschmierte Büchsen oder andere Lagerungsformen verwirklicht sein, die eine unabhängige Rotation der beiden Bahnführungsabschnitte 13 beziehungsweise 14 in bezug aufeinander ermöglichen. Dies schließt ein, daß einer der Bahnführungsabschnitte 13 beziehungsweise 14 auch still gesetzt werden kann, während der jeweils andere in Rotation begriffen ist. Bevorzugt erstrecken sich die Trichtereinlaufwalzen 7 bei doppeltbreiten Zeitungsrotationen beispielsweise über die gesamte Einlaufbreite beider Falztrichter 8 beziehungsweise 9. Jeweils einer der Führungsabschnitte 13, 14 ist dabei einem Falztrichter 8 beziehungsweise 9 zugeordnet. Sodaß über den Trichter 8 ein ein- oder mehrlagiger Bahnstrang unabhängig von über den Bahnführungsabschnit 14 in den Falztrichter 9 einlaufenden Bahnstrang verarbeitet werden kann.In the folding section 3 shown in Fig. 1 are in three superimposed levels 3.1, 3.2 or 3.3 pairs of folding former 8.9 lying side by side, over their Funnel lugs 20 run the longitudinally folded web strands there. The web guide roller 7 2 acts as a divided hopper inlet roller 7, with 2 independently mutually operable roller sections 13 and 14. The two roller sections 13 and 14 each have a drive 11 or 12. The Both roller sections 13 and 14 each have a drive 11 and 12. The two roller sections 13 and 14 are connected to one another in such a way that a roller section 13 or 14 the other roller section as Storage acts. For this purpose, a clutch can be placed between the roller sections 13 and 14 10 can be included, which contain a pin 10.1 or a recess 10.2, which a positive connection of the two roller sections 13 and 14 allow without hindering their independent rotation. Next A coupling 10 can also be ball bearings, lubricated bushings or other bearing forms be realized, the independent rotation of the two web guide sections 13 or 14 in relation to each other. This includes that one of the web guide sections 13 or 14 can also be stopped, while the other is rotating. The hopper inlet rollers preferably extend 7 for double-wide newspaper presses, for example, over the entire Infeed width of both formers 8 and 9 respectively one of the guide sections 13, 14 is assigned to a former 8 or 9. So about that Hopper 8 is a single or multi-layer web strand regardless of the web guide section 14 into the web 9 entering the former 9 can be processed.

Wenn vorliegend von mehreren Bahnsträngen die Rede ist, so ist darunter zu verstehen, daß durch bereits im Wendestangenüberbau 2 oder in der Vollsektion 3 vorgesehenen Längsschneideinrichtungen die Bahnen A, B, C und D in Teilbahnen A1, A2; B1, B2, C1, C2, D1 und D3 längsgeschnitten werden können. Analoges gilt für die Bahnen E, F, G und H, die mittels Längsschneideinheiten in Teilbahnen E1, E2, F1, F2, G1, G2, H1 und H2 geteilt werden können. Die einzelnen Teilbahnen können ihrerseits wieder aus mehreren Bahnlagen bestehen.If there are several web strands in the present case, this means that already provided in the turning bar superstructure 2 or in the full section 3 Longitudinal cutting devices the webs A, B, C and D in partial webs A1, A2; B1, B2, C1, C2, D1 and D3 can be cut lengthways. The same applies to the lanes E, F, G and H, by means of slitting units in partial webs E1, E2, F1, F2, G1, G2, H1 and H2 can be shared. The individual partial webs can in turn consist of several Railway layers exist.

In Fig. 3 ist eine Darstellung der Falzsektion im Überbau in vergrößerter Darstellung wiedergegeben.3 shows a representation of the folding section in the superstructure in an enlarged representation.

In drei Ebenen 3.1, 3.2 beziehungsweise 3.3 sind jeweils 2 Längsfalztrichter 8, 9 nebeneinander liegend angeordnet. Eine erfindungsgemäße Trichtereinlaufwalze 7 befindet sich oberhalb der Falztrichter 8 beziehungsweise 9, die sich in der Ebene 3.2 befinden.In three planes 3.1, 3.2 and 3.3 there are two longitudinal folding hoppers 8, 9 side by side arranged horizontally. A hopper inlet roller 7 according to the invention is located above the former 8 or 9, which are located in the level 3.2.

Über den Falztrichter 8 in der ersten Ebene 3.1 laufen die Teilbahnen H1, H2 aus der Druckgruppe 6, während über den danebenliegenden Falztrichter 9 die Teilbahnen E1, E2, F1 und F2 längs gefalzt werden. Die Teilbahnen E1, E2, F1, F2 laufen and den Ebenen 3.2 beziehungsweise 3.3 vorbei in das Zylinderteil 17 eines Falzapparates ein. Die längsgefalzten Teilbahnen H1, H2 laufen von einer geteilten Bahnführungswalze 7 ab und werden an der untersten Ebene 3.3 vorbei, ebenfalls in das Falzapparatzylinderteil 17 eingeführt.The partial webs H1, H2 run out of the fold former 8 in the first level 3.1 Printing group 6, while the partial webs E1, E2, F1 and F2 are folded lengthways. The partial webs E1, E2, F1, F2 run on levels 3.2 or 3.3 over into the cylinder part 17 of a folder. The longitudinally folded Partial webs H1, H2 run from a divided web guide roller 7 and become past the lowest level 3.3, also inserted into the folder cylinder part 17.

In der zweiten Ebene 3.2 befindet sich oberhalb der Längsfalztrichter 8, 9 die Trichereinlaufwalze 7, unterteilt in zwei Bahnführungsabschnitte 13 beziehungsweise 14 gemäß der Darstellung in Fig. 2 die den jeweils in unabhängiger Antrieb 11 beziehungsweise 12 zugeordnet sein kann.In the second level 3.2, above the longitudinal folding hoppers 8, 9, the hopper inlet roller is located 7, divided into two web guide sections 13 and 14 according to the Representation in FIG. 2 which is assigned to the respectively independent drive 11 or 12 can be.

Über den Bahnführungsabschnitt 13 laufen die Teilbahnen A1, A2, über den Bahnführungsabschnitt 14 die Teilbahnen G1, G2 nach Längsfalzung am Falztrichter 9 in das Falzapparatzylinderteil 17 ein. Die Teilbahnen A1, A2 hingegen laufen vor der untersten Falzebene 3.3 in das Falzapparatzylinderteil 16 ein.The partial webs A1, A2 run over the web guide section 13, over the web guide section 14 the partial webs G1, G2 after longitudinal folding on the former 9 in the Folder cylinder part 17 a. The sub-lanes A1, A2, however, run in front of the lowest Fold plane 3.3 into the folder cylinder part 16.

In der untersten Falzebene 3.3, die analog der Falzebene 3.1 konfiguriert ist, werden durch den Längsfalztrichter 8 die Teilbahnen B1, B2 und durch den Falztrichter 9 die Teilbahnen C1, C2 sowie D1 und D2 längsgefalzt. Diese laufen zusammen mit den in der Ebene 3.2 längsgefalzten Teilbahnen A1, A2 in das Falzapparatzylinderteil 16 ein. Mit der erfindungsgemäßen Anordnung der geteilten Trichtereinlaufwalze 7 ist es möglich, in der zweiten Ebene 3.2 der Falzsektion 3 entweder die Teilbahnen A1, A2 oder die Teilbahnen G1, G2 unabhängig voneinander zu führen. Abhängig von der Auflagenstärke läßt sich mit der geteilten Trichtereinlaufwalze 7 eine Führung der Teilbahnen in unterschiedliche Teilbahnstränge erreichen, so daß die Teilbahnen E1, E2, F1, F2, G1, G2 sowie H1 und H2 eine geringe Auflage allesamt einem separaten Falzapparatzuführer sind und der Druck dieser Auflage beendet werden kann, ohne die höhere Auflage, bestehend aus den Teilbahnen A1, A2, B1, B2, C1, C2 sowie D1 und D2 zu beeinträchtigen. Diese kann über die dem Falzapparat 16 zugeordnete separate Auslage 18 unabhängig von der Auslage 19 im Falzapparatzylinderteil 17 arbeiten.In the lowest fold level 3.3, which is configured analogously to fold level 3.1, are by the longitudinal fold former 8 the partial webs B1, B2 and through the folding former 9 the partial webs C1, C2 and D1 and D2 are longitudinally folded. These run together with those in level 3.2 longitudinally folded partial webs A1, A2 into the folder cylinder part 16. With the invention Arrangement of the divided hopper inlet roller 7, it is possible in the second level 3.2 of the folding section 3 either the partial webs A1, A2 or the partial webs G1, G2 to run independently. Depending on the number of copies, you can use the divided hopper inlet roller 7 guides the partial webs into different partial web strands reach so that the partial webs E1, E2, F1, F2, G1, G2 and H1 and H2 a small edition are all a separate folder feeder and the print this edition can be ended without the higher edition consisting of the partial webs A1, A2, B1, B2, C1, C2 as well as D1 and D2. This can be done via the Folder 16 associated separate delivery 18 regardless of the delivery 19 in Work folder cylinder part 17.

Das hier erläuterte Beispiel einer Bahnführung durch die Falzsektion 3 ist lediglich eines von vielen möglichen Beispielen der Bahnführung. Es könnte sich ebensogut bei den Teilbahnsträngen A1, A2, B1, B2, C1, C2 sowie D1 und D2 um den Auflagen geringeren Druckauftrag handeln und bei den Teilbahnsträngen E1, E2, F1, F2, G1, G2 sowie H2 und H2 um die Auflagen stärkere Auflage handeln. Auch könnte die Trichtereinlaufwalze 7 in einer anderen Ebene als der in Fig. 3 gezeigten Ebene 3.2 angeordnet werden, beispielsweise in allen drei Ebenen 3.1, 3.2, 3.3 der Falzsektion 3.The example of a web guide through the folding section 3 explained here is only one of many possible examples of web guidance. It might as well be with the partial web strands A1, A2, B1, B2, C1, C2 as well as D1 and D2 by the editions less Act a print job and for the partial web strands E1, E2, F1, F2, G1, G2 as well as H2 and H2 is the edition with a higher edition. The hopper inlet roller 7 in a different level than the level 3.2 shown in FIG. 3, for example in all three levels 3.1, 3.2, 3.3 of the folding section 3.

Die erfindungsgemäß vorgeschlagene Lösung erhöht die Flexibilität der Produktion auf Rollrotationen - insbesondere bei Zeitungsrotationen -ganz erheblich. Neben ihrem Einsatz als Trichtereinlaufwalze 7 in einer Falzsektion 3, lassen sich erfindungsgemäß geteilte Bahnführungswalzen auch als Bahneinzugswalzen, als Tänzerwalzen sowie als Bahnspannungswalzen und als Zugwalzen für die Materialbahn integriert in die jeweiligen Bahnpfade in der Rotation einbauen. Der Vollständigkeit halber sei erwähnt, daß es sich bei den in der Falzsektion 3 gemäß der vorliegenden Anmeldung hergestellten Formaten vorzugsweise um Tabloid oder einfache Querfalzformate handelt, die bei der Falzung in Zeitungsrotationsdruckmaschinen durchaus üblich sind. In den der Falzsektion 3 nachgeordneten Falzapparatzylinderteilen 16, 17 können sich an die solche Art vorgenommenen Tabloid oder Querfalzformate bereits in der Falzsektion 3 oberhalb der Zylinderteile Querfalzvorgänge, Doppelparallel-falzvorgänge sowie Deltafalzvorgänge anschließen, sodaß die in den Auslagen 18 beziehungsweise 19 ausgelegten Exemplare in allen gängigen Zeitungsformaten hergestellt werden können. The solution proposed according to the invention increases the flexibility of the production Rolling presses - especially with newspaper presses - are quite considerable. In addition to their use as a funnel inlet roller 7 in a folding section 3, can be divided according to the invention Web guide rollers also as web feed rollers, as dancer rollers and as web tension rollers and integrated into the respective web paths as traction rollers for the material web install in rotation. For the sake of completeness it should be mentioned that the in the folding section 3 formats produced according to the present application preferably are tabloid or simple cross fold formats that are used for folding in newspaper printing presses are quite common. In the subordinate to the folding section 3 Folder cylinder parts 16, 17 can adapt to the tabloid made in this way or cross fold formats already in the folding section 3 above the cylinder parts cross fold processes, Connect double parallel folding processes as well as delta folding processes, so that the in the Displays 18 or 19 copies in all common newspaper formats can be produced.
