Die Erfindung betrifft eine Wendeturmanordnung für eine Druckmaschine, insbesondere für den Zeitungsoffsetdruck.The invention relates to a turning tower arrangement for a printing press, in particular for newspaper offset printing.

Mit der zunehmenden Vielfalt von Zeitungs- und Magazinprodukten nehmen die Anforderungen an die Flexibilität von Druckmaschinen zu. Die Maschine muss möglichst rasch von einer Produktion auf die nächste umgestellt werden, sei es, dass das Produkt insgesamt wechselt oder auch, dass innerhalb eines Produkts nur ein Teil gewechselt werden muss, beispielsweise die regionalen Teile innerhalb einer überregionalen Zeitung.With the increasing variety of newspaper and magazine products, the Flexibility requirements of printing presses too. The machine must if possible be quickly switched from one production to the next, be it that the product changes overall or that only a part is changed within a product must, for example the regional parts within a national newspaper.

Wendestangenaufbauten, wie sie insbesondere zum Übereinanderführen von längs zu falzenden Bedruckbahnen verwendet werden, müssen diese Flexibilität fördern.Turning bar structures, such as those used for overlapping along folding printing webs are used must promote this flexibility.

Ein umstellbarer Wendeturm ist aus der DE 296 17 976 U1 bekannt. Der Turm ist vertikal zweigeteilt. Die Wendestangen sind in zwei übereinander angeordneten Schlitten gelagert, die in einem Gestell des Turms quer zur Einlaufrichtung der Bahn zwischen zwei Endstellungen verfahrbar sind, aus denen die übereinander geführten Bahnen in jeweils nachgeordnete Falztrichter auslaufen. A convertible turning tower is known from DE 296 17 976 U1. The tower is vertical divided in two. The turning bars are mounted in two slides arranged one above the other, that in a frame of the tower transverse to the direction of the web between two End positions are movable, from which the tracks run one above the other in each downstream fold former run out.

Aus der US-1,738,324 ist eine Mehrfarben-Rotationsdruckmaschine mit zwei in gerader Verlängerung der Bahneinlaufrichtung unmittelbar hintereinander angeordneten Wendetürme bekannt, bei der mehrere Bedruckstoffbahnen über Umlenkwalzen zwischen die Wendetürme geführt werden.From US-1,738,324 is a multi-color rotary printing press with two in a straight line Extension of the web entry direction arranged one behind the other Reversing towers are known in which several printing material webs between guide rollers between the turning towers are led.

Die DE-598 854 offenbart eine Zweirollen-Rotationsdruckmaschine für Schön- und Widerdruck mit zwei Gruppen von Druckwerken und einem zwischen ihnen angeordneten Falzwerk, wobei jeder Druckwerksgruppe zum Wenden und/oder Versetzen je eines Papierstranges unterschiedliche Wendestangenpaare und Umlenkwalzen zugeordnet sind. DE-598 854 discloses a two-roll rotary printing machine for beauty and Reverse printing with two groups of printing units and one arranged between them Folding unit, each printing unit group for turning and / or moving one each Paper strand different pairs of turning bars and deflection rollers are assigned.

Die Erfindung hat es sich zur Aufgabe gemacht, eine Wendeturmanordnung zu schaffen, mit der der Produktionsvielfalt und häufigen Produktionsumstellungen flexibel begegnet werden kann und die konstruktiv dennoch einfach ist.The invention has set itself the task of creating a turning tower arrangement with that can be flexibly countered to the diversity of production and frequent changes in production can and which is constructively simple.

Diese Aufgabe wird durch den Gegenstand von Anspruch 1 gelöst.This object is solved by the subject matter of claim 1.

Die Erfindung geht von einer Wendeturmanordnung aus, die einen Wendeturm umfasst, in dem Wendestangen in mehreren Ebenen übereinander angeordnet sind, um mehrere Bedruckbahnen bzw. Bedruckteilbahnen übereinander zu führen. Im allgemeinen werden die übereinander geführten Bahnen anschließend durch einen Falztrichter geführt, dort längs gefalzt, in einem nachgeordneten Falzapparat quer geschnitten und gefalzt und zum fertigen Druckprodukt ausgelegt.The invention is based on a turning tower arrangement which comprises a turning tower in the turning bars are arranged one above the other in several levels to create several To run printing webs or partial printing webs one above the other. In general, the overlapping webs then passed through a former, there along folded, cut in a subordinate folder and folded and finished Printed product designed.

Die erfindungsgemäße Wendeturmanordnung weist wenigstens zwei Wendetürme auf, die in Richtung einer in einen der beiden Wendetürme einlaufenden Bahn unmittelbar hintereinander angeordnet sind. Zwischen den beiden Wendetürmen befinden sich insbesondere keine Druckwerke.The turning tower arrangement according to the invention has at least two turning towers, which in Direction of a path entering one of the two turning towers immediately are arranged one behind the other. Are located between the two turning towers especially no printing units.

Zwei in einen der Wendetürme einlaufende Bahnen können bereits in diesem Wendeturm übereinander geführt werden, sie können jedoch auch beide durch diesen ersten Wendeturm hindurch in den unmittelbar dahinter angeordneten zweiten Wendeturm gefördert und dort übereinandergeführt werden. Sie können auch durch den zweiten Wendeturm hindurchgefördert und um Leitwalzen dieses zweiten Wendeturms umgelenkt durch den zweiten Wendeturm in die Gegenrichtung zurückgefördert und so gekehrt bereits im zweiten Wendeturm oder im ersten Wendeturm übereinander geführt werden. Schließlich kann die eine der beiden Bahnen im ersten Wendeturm und die andere der beiden Bahnen im zweiten Wendeturm mit weiteren Bahnen in geeigneter Weise übereinander geführt werden. Die Variationsfähigkeit hinsichtlich der übereinander zu führenden Bahnen und damit schließlich hinsichtlich des oder der fertigen Druckprodukte wird gegenüber herkömmlichen Einzelwendetürmen erheblich gesteigert.Two lanes entering one of the turning towers can already be in this turning tower over each other, but you can also both through this first turning tower conveyed into the second turning tower immediately behind and there be brought together. They can also be conveyed through the second turning tower and deflected around guide rollers of this second turning tower by the second The turning tower is conveyed back in the opposite direction and thus swept in the second Turn tower or one above the other in the first turn tower. Finally, the one of the two tracks in the first turning tower and the other of the two tracks in the second The turning tower with other tracks can be guided on top of one another in a suitable manner. The Ability to vary the webs to be guided one above the other and thus ultimately with regard to the finished print product or products is compared to conventional Single turn towers significantly increased.

Vorzugsweise ist die erfindungsgemäße Wendeturmanordnung zwischen zwei Drucktürmen der Druckmaschine angeordnet, so dass Bedruckbahnen von zwei Seiten in die Wendeturmanordnung einlaufen und dort wie vorstehend beschrieben übereinander geführt werden können. Sind dann auch noch, wie es einer weiter bevorzugten Ausführungsform entspricht, beidseits jedes Wendeturms der Wendeturmanordnung wenigstens je ein Falztrichter angeordnet, so können bereits vier Stränge von übereinander geführten Bahnen zu 2, 3 oder sogar 4 fertigen Druckprodukten weiterverarbeitet werden, je nachdem ob die längs gefalzten Bahnstränge hinter den Falztrichtern einzeln weiterverarbeitet oder in geeigneter Weise nochmals übereinander geführt werden.The turning tower arrangement according to the invention is preferably between two printing towers the printing press arranged so that printing webs from two sides in the turning tower arrangement run in and run over each other as described above can. Are then also, as corresponds to a further preferred embodiment, at least one former on each side of each turning tower of the turning tower arrangement Arranged, four strands of 2, 3 or even 4 finished printed products can be processed, depending on whether the lengthways folded web strands either individually processed behind the former or in a suitable one Way again on top of each other.

Wie bei üblichen Wendeturmanordnungen auch, sind Schneideinrichtungen zum Längsschneiden von in die Wendeturmanordnung einlaufenden Bahnen nur jeweils in Richtung der einlaufenden Bahn gesehen vor den einzelnen Wendetürmen angeordnet. Infolge der erfindungsgemäßen Anordnung von wenigstens zwei Wendetürmen mit solchen Schneidvorrichtungen kann jedoch eine Schneideinrichtung des einen Turms auch als Schneidvorrichtung für eine in den anderen Turm einlaufende und durch diesen anderen Turm hindurchgeförderte Bahn dienen.As with conventional turning tower arrangements, cutting devices are for Longitudinal cutting of webs entering the turning tower arrangement only in Arranged in the direction of the incoming web seen in front of the individual turning towers. As a result of the arrangement according to the invention of at least two turning towers with such However, cutting devices can also be used as a cutting device of the one tower Cutting device for one entering and through the other tower Serve through the tower.

Die Bahn B1 vom obersten Druckwerk des linken Druckturms 10 wird über nicht dargestellte Leitorgane bis unter die erste, unterste Ebene E1 des ersten Wendeturms 11 geführt. Dort wird sie um eine Leitrolle 15, die einer Zugwalze 16 benachbart ist, umgelenkt, um so eine ausreichende Umschlingung der Zugwalze 16 zu erzielen, anschließend um diese Zugwalze 16 geführt und dabei mittels eines gegen die Zugwalze 16 angestellten Kreismessers 17 längs geschnitten. Die Oberseite der Zugwalze 16 liegt in der ersten Wendestangenebene E1. Eine erste zwei-Platten-breite Teilbahn wird von der Zugwalze 16 in der ersten Wendestangenebene E1 durch den ersten Wendeturm 11 unbeeinflusst hindurch und in den zweiten Wendeturm 12 auf der gleichen Ebene E1 hineingefördert, dort quer zur Einlaufrichtung gewendet, gegebenenfalls auch gekehrt, und anschließend in die neue Richtung quer zur Einlaufrichtung aus dem zweiten Wendeturm 12 hinaus zu einem nachfolgenden Falztrichter gefördert. Die zweite durch das Längsschneiden entstandene Teilbahn aus B1 wird über mehrere Leitorgane zu einer über der ersten Wendestangenebene E1 liegenden Wendestangenebene E11 des ersten Wendeturms 11 geführt. In der Ebene E11 wird sie durch den ersten Wendeturm 11 unbeeinflusst hindurch ebenfalls in den zweiten Wendeturm 12 auf gleicher Ebene E11 gefördert, geeignet gewendet und gegebenenfalls gekehrt und quer zur Einlaufrichtung aus dem zweiten Wendeturm 12 zu einem nachfolgenden Falztrichter gefördert. Es kann sich hierbei um den gleichen Falztrichter handeln, zu dem auch die andere Teilbahn aus B1 gefördert wird. Da vorzugsweise zu beiden Seiten jedes Wendeturms 11 und 12, in Auslaufrichtung der Bahnen gesehen, jeweils wenigstens ein Falztrichter vorgesehen ist, können die beiden Teilbahnen aus B1 auch je einem dieser beiden Falztrichter zu den Seiten des zweiten Wendeturms 12 zugeführt werden.Figure 2 shows the turning tower arrangement 11, 12 of Figure 1 together with the printing towers 10 located directly on both sides of the turning tower arrangement 11, 12. In the production shown, a four-sheet wide printing web B1 runs from Left printing tower 10 first in the first immediately following this printing tower 10 Turn tower 11 and three four-plate-wide printing webs B2, B3 and B4 from the right Printing tower 10 first in the second right following this right printing tower Turn tower 12. The web B1 from the top printing unit of the left printing tower 10 is via guide organs, not shown, below the first, lowest level E1 of the first Turn tower 11 out. There it is around a guide roller 15, which is a pull roller 16 is adjacent, deflected so as to ensure sufficient wrap around the pull roller 16 achieve, then guided around this pull roller 16 and thereby by means of a against Pull roller 16 employed circular knife 17 cut lengthways. The top of the pull roller 16 lies in the first turning bar level E1. A first two-panel-wide partial web is being produced by the pull roller 16 in the first turning bar plane E1 through the first turning tower 11 unaffected and into the second turning tower 12 on the same level E1 conveyed in there, turned transversely to the direction of entry, possibly also swept, and then in the new direction transverse to the direction of entry from the second turning tower 12 conveyed to a subsequent former. The second by slitting Partial web created from B1 is turned over several guide elements to one above the first turning bar level E1 lying turning bar level E11 of the first turning tower 11 out. In level E11, it is also unaffected by the first turning tower 11 the second turning tower 12 promoted on the same level E11, appropriately turned and optionally swept and transverse to the direction of entry from the second turning tower 12 a subsequent former. It can be the same Acting former, to which the other sub-web from B1 is also promoted. There preferably on both sides of each turning tower 11 and 12, in the run-out direction of the webs seen, at least one former is provided, the two sub-webs from B1 also one of these two formers to the sides of the second turning tower 12 be fed.

Jeder der Wendetürme 11 und 12 weist in zwölf Ebenen E1 bis E12 vertikal übereinander angeordnete Wendestangen 21 und 22 auf. Die Wendestangen 21 und 22 sind gekreuzt. Auf jeder der Ebenen E1 bis E12 sind mehrere Wendestangen 21 parallel nebeneinander und dazu über Kreuz mehrere Wendestangen 22 ihrerseits parallel nebeneinander angeordnet, wie besser in Figur 5 zu erkennen ist. Die Anzahl der parallel oder gekreuzt nebeneinander angeordneten Wendestangen, sowohl 21 als auch 22, beträgt für eine vier-Platten-breite Druckmaschine max. vier Wendestangenpaare und für eine sechs-Platten-breite Druckmaschine sechs Wendestangenpaare.Each of the turning towers 11 and 12 points vertically one above the other in twelve planes E1 to E12 arranged turning bars 21 and 22. The turning bars 21 and 22 are crossed. On each of the levels E1 to E12 are a plurality of turning bars 21 in parallel next to each other and for this purpose, a plurality of turning bars 22, in turn, arranged in parallel next to one another, as can be seen better in FIG. The number of parallel or crossed next to each other arranged turning bars, both 21 and 22, is for a four-plate width Printing machine max. four pairs of turning bars and for a six-plate-wide printing machine six pairs of turning bars.

Pro Wendestangenebene E1 bis E12 ist mindestens ein Wendestangenpaar gekreuzt oder parallel angeordnet, wobei die Wendestangen (21, 22) unter sich vertikal versetzt sein können.At least one pair of turning bars is crossed or per turning bar level E1 to E12 arranged in parallel, the turning bars (21, 22) being vertically offset from one another can.

In der in den Figuren 1 bis 6 dargestellten Ausführung mit zwei Wendetürmen 11 und 12 mit je 12 Wendestangenebenen E1 bis E12 sowie pro Wendeturm 11 und 12 je wenigstens einem Falztrichter an der gleichen Seite der Wendeturmanordnung 11, 12 können pro Wendeturm die zwölf doppelseitigen Bahnen eines 24-seitigen Druckprodukts übereinander geführt werden. Indem die beiden längs gefalzten Bahnstränge hinter den Falztrichtern 1,2 oder 3,4 nochmals zusammengeführt werden entsteht ein für die Wendeturmanordnung der Figuren 1 bis 6 maximales Druckprodukt. Die Ausgestaltung der Wendeturmanordnung ist neben vier-Platten-breiten Druckmaschinen auch für sechs-Platten-breite Maschinen geeignet. Bei mindestens 2 Bahnen ist die Anordnung von zwei Wendetürmen (11, 12) sinnvoll.In the embodiment shown in FIGS. 1 to 6 with two turning towers 11 and 12 with 12 turning bar levels E1 to E12 each and at least 11 and 12 per turning tower a former can on the same side of the turning tower arrangement 11, 12 per The twelve double-sided webs of a 24-page printed product are stacked on top of each other be performed. By the two longitudinally folded web strands behind the formers 1,2 or 3, 4 are merged again for the turning tower arrangement Figures 1 to 6 maximum printed product. The design of the turning tower arrangement is in addition to four-plate-wide printing machines, also for six-plate-wide machines suitable. With at least 2 lanes, the arrangement of two turning towers (11, 12) meaningful.

In Bahnlaufrichtung vom jeweils benachbarten Druckturm 10 aus gesehen vor dem ersten Wendeturm 11 und vor dem ersten Wendeturm 12 sind mehrere Längsschneideinrichtungen 16, 17 übereinander angeordnet. Des weiteren sind jeder der Wendestangenebenen E1 bis E12 je ein Leitorgan unmittelbar vorgeordnet, über das die jeweilige Bahn bzw. die jeweilige Teilbahn in die entsprechende Ebene E1 bis E12 geführt wird. Diese mit ihrer Oberseite in den Ebenen E1 bis E12 liegenden Leitorgane werden entweder durch einfache Leitwalzen bzw. -rollen 18 oder durch die Zugwalzen 16 der Längsschneideinrichtungen 16, 17 gebildet. Zwischen den Wendetürmen 11 und 12 können zwar ebenfalls Leitwalzen oder -rollen zum Umlenken von durch den Wendeturm hindurch geförderten Bahnen vorgesehen sein, erforderlich ist dies jedoch nicht. Eine in einen der Wendetürme einlaufende Bahn, die aus diesem Wendeturm gekehrt wieder herausgeführt werden soll, kann aufgrund der erfindungsgemäßen Anordnung zweier Wendetürme zunächst durch beide Wendetürme einfach hindurchgefördert und um die an den Aussenseiten der Wendeturmanordnung 11, 12 vorhandenen Leitorgane 15, 16 bzw. 18 des jeweils anderen Wendeturms umgelenkt, durch den anderen Wendeturm hindurch zurück zu dem Wendeturm geführt werden, in den sie ursprünglich zunächst einlief und aus dem heraus sie gekehrt wieder auslaufen soll. Dies ist in Figur 2 am Beispiel der Bahn B3 vom rechten Druckturm 10 dargestellt.Seen in the direction of web travel from the adjacent printing tower 10 before the first Turning tower 11 and in front of the first turning tower 12 are several longitudinal cutting devices 16, 17 arranged one above the other. Furthermore, each of the turning bar levels E1 to E12 each have a leading organ directly upstream, via which the respective railway or the the respective partial web is guided into the corresponding level E1 to E12. This with her Top organs located in levels E1 to E12 are either by simple Guide rollers or rollers 18 or by the pull rollers 16 of the longitudinal cutting devices 16, 17 formed. Guide rollers or can also be used between the turning towers 11 and 12 rollers are provided for deflecting webs conveyed through the turning tower this is not necessary. A path entering one of the turning towers, the can be led out of this turning tower, due to the Arrangement of two turning towers according to the invention initially through both turning towers simply conveyed through and around the outside of the turning tower arrangement 11, 12 existing guide members 15, 16 and 18 of the other turning tower deflected by through the other turning tower back to the turning tower into which they originally came in first and from which it should run back again. This is shown in Figure 2 using the example of the web B3 from the right printing tower 10.

Die Bahn B3 wird in den auf den rechten Druckturm 10 folgenden zweiten Wendeturm 12 hinein und durch beide Wendetürme 12 und 11 zunächst unbeeinflusst einfach hindurch gefördert, über eine Zugwalze 16 des ersten Wendeturms 11 umgelenkt und mittels des an diese Zugwalze 16 angestellten Kreismessers 17 längs geschnitten. Die Zugwalze 16 dient gleichzeitig als Leitorgan für die Ebene E5, in der die über die Zugwalz 16 gekehrte Teilbahn aus B3 nach ihrem Hindurchfördern durch den ersten Wendeturm aus dem zweiten Wendeturm nochmals gekehrt ausläuft. Die andere Teilbahn aus B3 läuft ebenfalls zweimal gekehrt wieder aus dem zweiten Wendeturm 12 aus. Die Leitorgane des ersten Wendeturms, nämlich die Zugwalzen 16 und die Leitrollen bzw. Leitwalzen 18, wirken bzgl. dieser beiden Teilbahnen aus B3 wie bei herkömmlichen Wendetürmen bekannte Bay-Win-dow-Einrichtungen. Ferner wird die Schneideinrichtung 16, 17 des ersten Wendeturms 11 als Schneideinrichtung für den zweiten Wendeturm 12 genutzt.The web B3 is in the second turning tower 12 following the right printing tower 10 into and through both turning towers 12 and 11 initially unaffected conveyed, deflected via a pull roller 16 of the first turning tower 11 and by means of the this traction roller 16 employed circular knife 17 cut lengthways. The pull roller 16 is used at the same time as a guide for level E5, in which the swept over the drawing roller 16 Partial web from B3 after being conveyed through the first turning tower from the second Turn tower runs out again swept. The other part of B3 also runs twice swept out of the second turning tower 12 again. The guiding organs of the first turning tower, namely the pull rollers 16 and the guide rollers or guide rollers 18 act with respect to this Both sub-lanes made of B3 as well as known Bay Win-dow facilities with conventional turning towers. Furthermore, the cutting device 16, 17 of the first turning tower 11 as Cutting device used for the second turning tower 12.

In der in Figur 3 alternativen Führung der beiden Bahnen B1 und B3 wird die untere der beiden Teilbahnen aus B3 lediglich einmal gekehrt, während die obere Teilbahn aus B3 über zwei Leitrollen 19 des zweiten Wendeturms 12, die zwischen den beiden Wendetürmen 11 und 12 angeordnet sind, auf eine höhere Ebene E8 des zweiten Wendeturms geführt und dabei gekehrt wird, so dass sie nach nochmaligem Kehren in der Wendestangenebene E8 wieder aus dem zweiten Wendeturm 12 ausläuft. Da die obere der beiden Teilbahnen aus B3 durch die beiden als Bay-Window-Einrichtungen wirkenden Leitrollen 19 des zweiten Wendeturms 12 gekehrt wird, ist die in Figur 3 gegenüber in Figur 2 etwas vereinfachte Bahnführung der oberen Teilbahn aus B1 möglich. Der den zweiten Wendeturm 12 verlassende Bahnstrang unterscheidet sich von dem der Figur 2 dadurch, dass die untere Teilbahn aus B3 nur einmal gekehrt worden ist.In the alternative guidance of the two tracks B1 and B3 in FIG. 3, the lower one is two partial webs from B3 swept only once, while the upper partial web from B3 over two guide rollers 19 of the second turning tower 12, which are between the two turning towers 11 and 12 are arranged, led to a higher level E8 of the second turning tower and is swept so that after repeated sweeping in the turning bar level E8 again runs out of the second turning tower 12. Since the upper of the two partial webs from B3 by the two guide rollers 19 of the second, which act as bay window devices Turning tower 12 is swept, is somewhat simplified in Figure 3 compared to Figure 2 The upper part of the web can be guided from B1. The second turning tower 12 Leaving web strand differs from that of Figure 2 in that the lower Partial train from B3 has only been swept once.

Figur 4 zeigt ein Produktionsbeispiel, in dem Bahnen sowohl im ersten Wendeturm 11 als auch im zweiten Wendeturm 12 übereinander geführt werden. Zu erkennen ist insbesondere, wie Teilbahnen aus Bahnen B1 und B5 vom linken Druckturm 10 durch den diesem Druckturm 10 unmittelbar folgenden ersten Wendeturm 11 hindurch zum zweiten Wendeturm 12 geführt und dort über weitere Teilbahnen aus den Bahnen B2, B3 und B4 vom rechten Druckturm geführt werden. Ebenso wird eine der Teilbahnen aus B2 vom rechten Druckturm durch den zweiten Wendeturm 12 hindurch in den ersten Wendeturm 11 gefördert und dort über eine der Teilbahnen vom linken Druckturm geführt. Dieses wechselseitige Übereinanderführen von Druckbahnen, d.h. vom linken Druckturm 10 zum rechten, zweiten Wendeturm 12 und vom rechten Druckturm 10 zum linken, ersten Wendeturm 11, steigert hinsichtlich der Produktionsvielfalt und Umstellbarkeit die Flexibilität beim Übereinanderführen von Druckbahnen erheblich. Figure 4 shows a production example in which webs both in the first turning tower 11 and also be guided one above the other in the second turning tower 12. It can be seen in particular like partial webs from webs B1 and B5 from the left printing tower 10 through this Printing tower 10 immediately following first turning tower 11 to the second Turning tower 12 led and there over further sub-lanes from the lanes B2, B3 and B4 from the right pressure tower. Likewise, one of the partial webs from B2 is right pressure tower through the second turning tower 12 into the first turning tower 11 promoted and led there via one of the partial webs from the left printing tower. This mutual superimposition of printing webs, i.e. from the left printing tower 10 to right, second turning tower 12 and from the right printing tower 10 to the left, first Turn tower 11, increases in terms of production diversity and convertibility Flexibility in overlaying printing webs considerably.

Im Ausführungsbeispiel der Figur 4 werden fünf volle Bahnen zu 1/2- und 1/4-Bahnen längs geschnitten und die so entstandenen Teilbahnen in der dargestellten Weise zu zwei Bahnsträngen, ein Bahnstrang pro Wendeturm, übereinandergeführt.In the exemplary embodiment in FIG. 4, five full webs become 1/2 and 1/4 webs lengthways cut and the resulting partial webs in the manner shown to two Web strands, one web strand per turning tower, overlapped.

Den beiden Wendetürmen 11 und 12 sind jeweils in beiden Auslaufrichtungen der Bahnen Falztrichter 1, 2, 3 und 4 nachgeordnet. Desweiteren sind zu den Seiten der Wendetürme 11 und 12 eine der Anzahl der Wendestangenebenen E1 bis E12 entsprechender Anzahl von Leitrollen 30 untereinander angeordnet, die als Bay-Window-Einrichtungen wirkend die im Wendestangenbereich gekehrten Bahnen nochmals kehrend in den Wendestangenbereich zurückführen können. Unter den beiden Trichterpaaren 1,2 und 3,4 ist jeweils ein Falzapparat 7 (Fig. 1) angeordnet.In Figure 5, the turning tower arrangement of Figures 1 to 4 is shown in plan view. The Both turning towers 11 and 12 are in both directions of the web exit Downstream of the former 1, 2, 3 and 4. Furthermore, 11 are on the sides of the turning towers and 12 a number corresponding to the number of turning bar planes E1 to E12 Guide rollers 30 arranged one below the other, which act as bay window devices in the Turn the turning bar area back into the turning bar area can. There is a folder under each of the two pairs of hoppers 1,2 and 3,4 7 (Fig. 1) arranged.

Figur 6 zeigt die Wendeturmanordnung der Figuren 1 bis 5 in einer Ansicht von der einlaufenden Bahn her gesehen. Die übereinander geführten Teilbahnen laufen über die Leitrollen 30 aus dem dargestellten zweiten Wendeturm 12 aus, wobei sie unter oder über die ausgangsseitigen Leitrollen 30 umgelenkt und mittels eines Fächers 40, der mit weiteren Leitrollen 41 bestückt ist, zusammengeführt, um anschließend über eine Trichterwalze und eine weitere Zugwalze von oben in die Trichter 3, 4 einzulaufen. Die Anordnung bei den gegenüberliegenden Trichtern 1, 2 entspricht der der Trichter 3, 4.Figure 6 shows the turning tower arrangement of Figures 1 to 5 in a view from the seen incoming web. The partial webs run one above the other run over the Guide rollers 30 from the illustrated second turning tower 12, being below or above the output-side guide rollers 30 are deflected and by means of a fan 40, which with further Guide rollers 41 is assembled, brought together to then over a hopper roller and run another pull roller into the funnels 3, 4 from above. The arrangement with the opposite funnels 1, 2 corresponds to that of funnels 3, 4.

In Figur 7 ist eine erweiterte Wendeturmanordnung mit dem ersten Wendeturm 11, dem zweiten Wendeturm 12 und einem zwischen diesen beiden angeordneten dritten Wendeturm 13 dargestellt. Alle drei Wendetürme 11, 12 und 13 sind bzgl. ihrer Wendestangen 21 und 22 gleich aufgebaut. Die Wendetürme 11 und 12 entsprechen denjenigen nach den Figuren 1 bis 6. Lediglich für den dritten Wendeturm 13 sind keine eigenen Schneideinrichtungen 16, 17 vorgesehen. Für die in diesem dritten Wendeturm 13 übereinander zu führenden Teilbahnen werden die an den jeweils einander abgewandten Seiten des ersten Wendeturms 11 und des zweiten Wendeturms 12 angeordneten Schneideinrichtungen 16, 17 mitgenutzt.FIG. 7 shows an expanded turning tower arrangement with the first turning tower 11, the second turning tower 12 and a third turning tower arranged between these two 13 shown. All three turning towers 11, 12 and 13 are with respect to their turning bars 21 and 22 constructed the same. The turning towers 11 and 12 correspond to those according to the figures 1 to 6. Only for the third turning tower 13 are no separate cutting devices 16, 17 provided. For the one above the other in this third turning tower 13 The partial webs are those on the sides of the first turning tower that face away from each other 11 and the second turning tower 12 arranged cutting devices 16, 17 are used.

Im Ausführungsbeispiel der Figur 7 werden sechs Bahnen längs geschnitten und die so entstandenen Teilbahnen in der dargestellten Weise zu drei Bahnsträngen, ein Bahnstrang pro Wendeturm, übereinandergeführt.In the exemplary embodiment in FIG. 7, six webs are cut lengthways and so created partial webs in the manner shown to three web strands, one web strand per turning tower, one on top of the other.
