Abstract

A turning bar arrangement for redirecting the path of travel of a material web utilizes at least one turning bar and at least one register roller. The web of material is caused to be enwrapped about both and extends between both to define a plane. When viewed in a direction perpendicular to this plane, the turning bar and the register roller do not overlap.

Description

Die Erfindung betrifft eine Wendestangenanordnung und Verfahren zum Umlenken einer Warenbahn gemäß dem Oberbegriff des Anspruches 1 oder 9.The invention relates to a turning bar arrangement and method for deflecting a web according to the preamble of claim 1 or 9.

In Rotationsdruckmaschinen werden im allgemeinen Materialbahnen, insbesondere Papierbahnen bedruckt, deren Breite ein Vielfaches der Breite des fertigen Druckerzeugnisses beträgt. Um aus der bedruckten Bahn das fertige Druckerzeugnis herzustellen, ist es notwendig, diese Bahn in eine Mehrzahl von Teilbahnen zu zerschneiden, die zunächst parallel zueinander geführt werden, die aber übereinandergelegt werden müssen, um dann zum fertigen Druckerzeugnis, meist durch Falzen in Längs- und Querrichtung und Querschneiden, weiterverarbeitet zu werden.
Beim Querschneiden der übereinandergelegten Materialbahnen ist es wichtig, dass Druckseiten auf den einzelnen Materialbahnen exakt in Phase zueinander ausgerichtet sind, so dass beim Querschneiden alle Materialbahnen jeweils an einer Grenze zwischen zwei Seiten durchtrennt werden. Zu diesem Zweck werden Registerwalzen eingesetzt, deren Verstellbarkeit es ermöglicht, die Länge des Weges einer Materialbahn durch die Wendestangenanordnung jeweils so einzustellen, dass auf den verschiedenen Bahnen Seiten, die zu einer Signatur verarbeitet werden sollen, exakt übereinander zu liegen kommen.In rotary printing machines material webs, especially paper webs are printed in general, the width of which is a multiple of the width of the finished printed product. In order to produce the finished printed product from the printed web, it is necessary to cut this web into a plurality of sub-webs, which are initially performed parallel to each other, but must be superimposed, then to the finished printed product, usually by folding in longitudinal and Cross direction and cross cutting, to be further processed.
When cross-cutting the superimposed material webs, it is important that printed pages on the individual material webs are aligned exactly in phase with each other, so that when cutting across all material webs are severed at a boundary between two sides. For this purpose, register rollers are used whose adjustability makes it possible to adjust the length of the path of a material web through the turning bar arrangement in each case so that come to lie on the different paths pages that are to be processed to a signature exactly above the other.

Ein Beispiel einer solchen Wendestangenanordnung ist aus US 37 34 487 A bekannt. Diese Wendestangenanordnung umfasst eine erste Wendestange, die quer zu einer Zufuhrrichtung der umzulenkenden Materialbahn verschiebbar ist, sowie zwei Registerwalzen und eine Registerwalze. Die Registerwalze ist in einer unterhalb der Wendestange liegenden Ebene verschiebbar. Wenn eine große Zahl von Materialbahnen übereinandergelegt werden soll, so wird hierzu ein Stapel von übereinander angeordneten Wendestangenanordnungen eingesetzt. Es genügt jedoch bereits eine geringe Zahl von übereinanderzulegenden Materialbahnen, damit dieser Stapel bei der bekannten Wendestangenanordnung übermannshoch wird, was ihre Wartung und das Einziehen der Materialbahnen bei einem Auftragswechsel erheblich verkompliziert.An example of such a turning bar arrangement is known from US 37 34 487 A. This turning bar arrangement comprises a first turning bar, which is displaceable transversely to a feed direction of the material web to be deflected, and two register rolls and a register roll. The register roller is displaceable in a lying below the turning bar level. If a large number of material webs to be superimposed, so this is a stack of stacked Turning bar arrangements used. However, it is sufficient already a small number of übereinanderzulegenden material webs, so that this stack is übermannshoch in the known turner bar assembly, which considerably complicates their maintenance and retraction of the webs in a job change.

Durch die DE 38 16 900 A1 ist eine Einrichtung zum Versetzen von schmalen Papierbahnen in Form von Teilpapierbahnen bekanntgeworden.By DE 38 16 900 A1 discloses a device for moving narrow paper webs in the form of partial paper webs has become known.

Die DE-AS 17 61 899 zeigt höhenversetzte Wendestangen.DE-AS 17 61 899 shows vertically offset turning bars.

Die US 37 34 487 A zeigt zwei dreieckartig angeordnete Wendestangen, von denen eine Materialbahn auf eine Registerwalze führbar ist.The US 37 34 487 A shows two triangularly arranged turning bars, of which a material web on a register roller is feasible.

Die EP 0 784 590 B1 zeigt eine Wendeeinrichtung, bei der eine Führungswalze und die Wendestangen unterschiedlichen Durchmesser aufweisen. Die unter 90° zueinander angeordneten Wendestangen weisen gleichen Durchmesser auf.EP 0 784 590 B1 shows a turning device in which a guide roller and the turning bars have different diameters. The turning bars arranged at 90 ° to each other have the same diameter.

Die EP 0 342 491 A2 die als nächister stand der technik auzusehen ist offenbart eine Wendestangenanordnung mit einer von einer Materialbahn umschlungenen ersten Wendestange und einer von der Materialbahn umschlungenen Registerwalze. Dabei sind die Wendestangen und die Registerwalze überdeckungsfrei angeordnet.EP 0 342 491 A2 which is considered to be the next state of the art discloses a turner bar arrangement with a first turner bar wrapped around by a material web and a register roller wrapped around the material web. The turner bars and the register roller are arranged without overlapping.

Die US 34 34 639 A und die US 38 09 303 A zeigen Wendestangenanordnungen, wobei mehrere Wendestangen von einer Materialbahn umschlungen sind und neben den Wendestangen Umlenkwalzen überdeckungskei angeordnet sind.The US 34 34 639 A and US 38 09 303 A show turner bar arrangements, wherein a plurality of turner bars are wrapped by a material web and in addition to the turning bars deflection rollers overlap Turkey are arranged.

Durch die DE 87 17 253 U1 ist eine Vorrichtung zum Umlenken von Teilbahnen bekannt. Dabei sind an einem gemeinsamen schwenkbaren Halter zwei einseitig gelagerte Wendestangen angeordnet.DE 87 17 253 U1 a device for deflecting partial webs is known. In this case, two cantilevered turning bars are arranged on a common pivotable holder.

Der Erfindung liegt die Aufgabe zugrunde, eine Wendestangenanordnung und Verfahren zum Umlenken einer Warenbahn zu schaffen.The invention has for its object to provide a turner bar assembly and method for deflecting a web.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 oder 9 gelöst.The object is achieved by the characterizing features of claim 1 or 9.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die Bauhöhe der Wendestangenanordnung klein gehalten werden kann, so dass die Zahl der Wendestangenanordnungen, die innerhalb einer vorgegebenen Bauhöhe übereinander montiert werden können, vergrößert ist. So kann die Zahl von Materialbahnen, die in einem Stapel von Wendestangenanordnungen übereinandergelegt werden können, vergrößert werden, ohne dass dafür der Stapel eine Höhe haben muss, die es einer Bedienungsperson schwierig macht, einzelne Wendestangenanordnungen des Stapels zu erreichen, um diese zu warten oder eine Materialbahn einzuziehen.The advantages achieved by the invention are in particular that the height of the turning bar assembly can be kept small, so that the number of turning bar arrangements that can be mounted one above the other within a predetermined height, is increased. Thus, the number of webs that can be superimposed in a stack of turner bar assemblies can be increased without the need for the stack to have a height that makes it one Operator difficult to reach individual turning bar arrangements of the stack to wait for them or feed a web.

Ein zwischen der ersten Wendestange und der Registerwalze verlaufender Abschnitt der Bahn definiert eine erste Ebene, die bei den herkömmlichen Wendestangenanordnungen im wesentlichen horizontal ist. Da die Wendestange und die Registerwalze, betrachtet aus einer zu dieser Ebene senkrechten Richtung, nicht überlappen, können sie, betrachtet aus einer zu der Ebene parallelen Richtung, überlappend angeordnet werden, so dass die Bauhöhe reduziert werden kann.A portion of the track extending between the first turning bar and the registration roller defines a first plane which is substantially horizontal in the conventional turning bar arrangements. Since the turning bar and the register roller do not overlap, as viewed from a direction perpendicular to this plane, they can be overlapped, as viewed from a direction parallel to the plane, so that the height can be reduced.

Eine besonders effektive Nutzung des zur Verfügung stehenden Bauvolumens ergibt sich, wenn die erste Wendestange und die Registerwalze auf einer gleichen Seite dieser ersten Ebene angeordnet sind.A particularly effective use of the available construction volume results when the first turning bar and the register roller are arranged on the same side of this first level.

Wenn die Registerwalze einen größeren Durchmesser als die erste Umlenkstange aufweist, so kann die um die Umlenkstange und die Registerwalze herumgeführte Materialbahn die Umlenkstange kreuzend abgeführt werden, ohne dass hierfür zusätzliche Umlenkelemente erforderlich sind.If the register roller has a larger diameter than the first deflection bar, then the material web guided around the deflection bar and the register roller can be removed by crossing the deflection bar, without the need for additional deflection elements.

Für eine Wendestangenanordnung mit zur Einlaufrichtung der Bahn paralleler Auslaufrichtung wird eine zweite Wendestange benötigt, und die Materialbahn ist zweckmäßigerweise der Reihe nach um die erste Wendestange, die Registerwalze und die zweite Wendestange herumschlingbar.For a turning bar assembly with the direction of entry of the web parallel discharge direction, a second turning bar is required, and the web is suitably herumschlingbar in order around the first turning bar, the registration roller and the second turning bar.

Wenn wenigstens eine der zwei Wendestangen aus einer zu der anderen Wendestange parallelen Orientierung in eine orthogonale Orientierung umstellbar ist, so erlaubt dies, die Wendestangenanordnung wahlweise mit paralleler oder mit antiparalleler Ein- und Auslaufrichtung zu betreiben.If at least one of the two turning bars can be converted from an orientation parallel to the other turning bar into an orthogonal orientation, then this allows the turning bar arrangement to be operated optionally with parallel or antiparallel entry and exit directions.

Eine schnelle und exakte Umstellung der Orientierung der umstellbaren Wendestange wird erreicht, wenn die Wendestange um eine Achse drehbar ist, die die Wendestange in einem Abstand von einem ihrer Längsenden schneidet, und an diesem Längsende eine Markierung angebracht ist, die in der parallelen bzw. der orthogonalen Orientierung mit jeweils einer von zwei komplementären Markierungen an einem Träger der Wendestange in Deckung bringbar ist. So genügt es, beim Umstellen der Wendestange die Deckungsgleichheit der Markierungen zu überprüfen, um sicher zu sein, dass die Wendestange exakt winkeleingestellt ist.A quick and accurate changeover of the orientation of the reversible turning bar is achieved when the turning bar is rotatable about an axis that intersects the turning bar at a distance from one of its longitudinal ends and at that longitudinal end a mark is placed in the parallel or orthogonal orientation with one of two complementary markings on a support of the turning bar can be brought into coincidence. So it is sufficient to check when adjusting the turning bar, the congruence of the markers to be sure that the turning bar is set exactly angle.

Zusätzlich vereinfacht ist das exakte Einstellen der Wendestange dann, wenn die Markierungen eine Raumform aufweisen und in formschlüssigen Eingriff bringbar sind. Bei einer solchen Konstruktion garantiert bereits der Eingriff der Markierungen eine exakte Ausrichtung der Wendestange, ohne dass die Ausrichtung von einer Bedienungsperson aufwendig überprüft werden muss.In addition, the precise adjustment of the turning bar is simplified if the markings have a spatial form and can be brought into positive engagement. With such a design, the engagement of the markings already guarantees an exact alignment of the turning bar, without having to laboriously check the alignment of an operator.

Fig. 1 zeigt eine Draufsicht auf eine Wendestangenanordnung gemäß einer ersten Ausgestaltung der vorliegenden Erfindung. Zwischen zwei Seitengestellen 01, die mit entsprechenden Seitengestellen eines der Wendestangenanordnung vorgegliederten (nicht dargestellten) Längsschneidapparates verbunden sind, erstrecken sich, vertikal in verschiedenen Ebenen gestaffelt, zwei Führungsprofile 02, an denen jeweils ein Träger 03; 04 für eine Wendestange 06 bzw. 07 verschiebbar und arretierbar angeordnet ist. Die Seitengestelle 01 der Wendestangenanordnung fluchten annähernd mit den Seitengestellen von Druckeinheiten einer zugehörigen Rotationsdruckmaschine. Eine erste dieser Wendestangen 07 ist hier mit ihrem Träger 04 an einem Längsende starr verbunden. Die zweite Wendestange 06 ist mit ihrem Träger 03 durch einen um eine horizontale, zur Ebene der Fig. 1 parallele Achse drehbaren Schaft 09 verbunden, wobei die Achse die zweite Wendestange 06 in einem Abstand von deren dem Träger 03 zugewandten Längsende 11 kreuzt. Der Schaft 09 ist mit Hilfe eines am Träger 03 angebrachten Spannhebels 12 feststellbar. Der Träger 03 weist zwei Markierungen 13 auf, die hier als Vorsprünge ausgebildet sind, deren genaue Position am Träger 03 in drei Raumrichtungen justierbar ist. Die zweite Wendestange 06 trägt an ihrem Längsende 11 eine komplementäre Markierung in Form einer Aussparung, die so geformt ist, dass sie einen formschlüssigen Eingriff einer der Markierungen 13 ermöglicht. Durch geeignete Justage der Position der Markierungen 13 kann sichergestellt werden, dass die zweite Wendestange 06 in ihrer in der Fig. 1 gezeigten Position exakt parallel zur ersten Wendestange 07 ist, oder, nach Schwenken der zweiten Wendestange 06 um 180° um die Achse des Schaftes 09 und in Eingriff bringen der Markierungen 13 exakt orthogonal zur ersten Wendestange 07 orientiert ist.Fig. 1 shows a plan view of a turning bar assembly according to a first embodiment of the present invention. Between two side frames 01, which are connected to corresponding side frames of one of the turning bar arrangement vorgegliederten (not shown) Längsschneidapparates extend vertically staggered in different planes, two guide profiles 02, to each of which a carrier 03; 04 is arranged displaceable and lockable for a turning bar 06 and 07, respectively. The side frames 01 of the turning bar assembly are aligned approximately with the side frames of printing units of an associated rotary printing machine. A first of these turning bars 07 is rigidly connected here with its carrier 04 at one longitudinal end. The second turning bar 06 is connected to its carrier 03 by a shaft 09 which is rotatable about a horizontal axis parallel to the plane of FIG. 1, the axis crossing the second turning bar 06 at a distance from its longitudinal end 11 facing the carrier 03. The shaft 09 can be fixed with the aid of a clamping lever 12 attached to the carrier 03. The carrier 03 has two markings 13, which are formed here as projections whose exact position on the carrier 03 is adjustable in three spatial directions. The second turning bar 06 carries at its longitudinal end 11 a complementary mark in the form of a recess which is shaped so as to enable a positive engagement of one of the markers 13. By suitable adjustment of the position of the markings 13 it can be ensured that the second turning bar 06 is exactly parallel to the first turning bar 07 in its position shown in FIG. 1 or, after pivoting the second turning bar 06 by 180 ° about the axis of the shank 09 and engaging the markers 13 is oriented exactly orthogonal to the first turning bar 07.

Die Träger 03; 04 weisen jeweils einen Anschlußstutzen 08 für Druckluft auf, die durch Bohrungen im Träger 03 oder 04 in die Wendestange 06 bzw. 07 geleitet wird und durch Bohrungen an der Umfangsfläche der Wendestange 06 bzw. 07 austritt, um ein Luftkissen zwischen der Wendestange 06; 07 und einer um sie herumgeschlungenen Materialbahn 22 zu bilden.The carriers 03; 04 each have a connecting piece 08 for compressed air, which is passed through holes in the carrier 03 or 04 in the turning bar 06 and 07 and exits through holes on the peripheral surface of the turning bar 06 and 07, to an air cushion between the turning bar 06; 07 and a web of material wrapped around them 22 to form.

Jeweils seitlich außerhalb der Seitengestelle 01 sind auf der Seite der ersten Wendestange 07 eine Registerwalze 14 und auf der Seite der zweiten Wendestange 06 eine Umlenkwalzenanordnung 16 montiert Die Registerwalze 14 ist an einem an einer Schiene 17 verschiebbaren Gleitstein 18 montiert. Ein mit dem Gleitstein 18 fest verbundener Gewindekörper 19 ist mit einer Gewindestange 21 im Eingriff, die durch einen (nicht dargestellten) Motor drehantreibbar ist, um die Registerwalze 14 in Richtung des Doppelpfeils P zu verschieben. Die Registerwalze 14 ist außerhalb jeweils einer von dem jeweiligen Seitengestell zugehöriger Druckeinheiten festgelegten Ebene und außerhalb eines zwischen den Ebenen liegenden Raumes angeordnet.In each case laterally outside of the side frames 01, a register roller 14 and on the side of the second turning bar 06, a guide roller assembly 16 are mounted on the side of the first turning bar 07. The register roller 14 is mounted on a slide 17 slidable on a rail 18. A threaded body 19 fixedly connected to the sliding block 18 is engaged with a threaded rod 21 rotatably driven by a motor (not shown) for shifting the register roller 14 in the direction of the double arrow P. The registration roller 14 is disposed outside each of a predetermined by the respective side frame associated printing units level and outside a lying between the planes space.

Die Materialbahn 22 ist in der Fig. 1 transparent dargestellt; lediglich ihre Ränder sind durch dick durchgezogene Linien herausgehoben. Die Materialbahn 22 ist der Reihe nach um die zweite Wendestange 06, die Umtenkwalzenanordnung 16, die Registerwalze 14 und die erste Wendestange 07 herumgeschlungen. Für die Zwecke der vorliegenden Beschreibung wird angenommen, dass sie in Richtung eines Pfeils T bewegt wird; selbstverständlich wäre auch eine Bewegung in entgegengesetzter Richtung möglich. Ein einlaufender Abschnitt 23 erstreckt sich vom Eingang der Wendestangenanordnung bis zur zweiten Wendestange 06. Wie insbesondere in Fig. 2 zu erkennen ist, umschlingt die Materialbahn 22 die zweite Wendestange 06 von oben nach unten, erreicht die Umlenkwalzenanordnung 16, wird dort um 180° umgelenkt und verläuft in einem geringen Abstand von der Unterseite der zweiten Wendestange 06 quer durch die gesamte Wendestangenanordnung bis hin zur Oberseite der Registerwalze 14. Von der Unterseite der Registerwalze 14 erstreckt sich ein Abschnitt 26 der Materialbahn 22 in einer Ebene E zur Unterseite der ersten Wendestange 07. Die Materialbahn 22 umschlingt die erste Wendestange 07 von unten nach oben, so dass ein auslaufender Abschnitt 24 der Materialbahn 22 schließlich ausgehend von der Oberseite der Wendestange 07 die Wendestangenanordnung verlässt.The material web 22 is shown transparent in FIG. 1; only their edges are highlighted by thick solid lines. The web 22 is looped around the second turning bar 06, the Umtenkwalzenanordnung 16, the register roller 14 and the first turning bar 07 in order. For the purposes of the present description, it is assumed that it is moved in the direction of an arrow T; Of course, a movement in the opposite direction would be possible. An incoming portion 23 extends from the entrance of the turning bar assembly to the second turning bar 06. As can be seen in particular in Fig. 2, the web 22 wraps around the second turning bar 06 from top to bottom, reaches the Umlenkwalzenanordnung 16, is deflected there by 180 ° and extends at a small distance from the bottom of the second turning bar 06 across the entire turning bar assembly up to the top of the register roller 14. From the bottom of the register roller 14, a portion 26 of the web 22 extends in a plane E to the bottom of the first turning bar 07th The material web 22 wraps around the first turning bar 07 from bottom to top so that an outgoing section 24 of the material web 22 finally leaves the turning bar arrangement starting from the top of the turning bar 07.

Wie man leicht sieht, ermöglicht die Anordnung der Umlenkwalzenanordnung 16 und der Registerwalze 14 seitlich versetzt jenseits der Seitengestelle 01 und außerhalb des Bewegungsbereiches der Wendestangen 06, 07 entlang der Führungsprofile 02, die Bauhöhe der Wendestangenanordnung gering zu halten. Da der Durchmesser der Registerwalze 14 größer als der der ersten Wendestange 07 ist, können beide auf der gleichen Seite der Ebene E angeordnet sein, was zu einer weiteren Reduzierung der Bauhöhe beiträgt. Da sowohl die Registerwalze 14 als auch die erste Wendestange 07 oberhalb der Ebene E liegen, die durch den sich zwischen Registerwalze 14 und erster Wendestange 07 erstreckenden Abschnitt 26 der Materialbahn 22 definiert ist, kann der Höhenunterschied zwischen einlaufendem und auslaufendem Abschnitt 23, 24 noch geringer gehalten werden, als es der Bauhöhe der Wendestangenanordnung entspricht.As you can easily see, the arrangement of the guide roller assembly 16 and the register roller 14 allows laterally offset beyond the side frames 01 and outside the range of movement of the turning bars 06, 07 along the guide rails 02 to keep the height of the turning bar assembly low. Since the diameter of the register roller 14 is greater than that of the first turning bar 07, both can be arranged on the same side of the plane E, which contributes to a further reduction of the height. Since both the registration roller 14 and the first turning bar 07 are above the plane E defined by the section 26 of the web 22 extending between the register roller 14 and the first turning bar 07, the height difference between the incoming and outgoing sections 23, 24 can be even lower are held, as it corresponds to the height of the turning bar assembly.

Fig. 3 zeigt stark schematisiert einen Stapel, in dem eine Mehrzahl von Wendestangenanordnungen 27 vom in Fig. 1 und 2 gezeigten Typ übereinander angeordnet sind, gesehen aus Richtung des Pfeils IV in Fig. 1. Der Stapel umfasst hier vier übereinanderliegende Wendestangenanordnungen 27, ihre Zahl kann aber auch größer oder kleiner sein. Jeder Wendestangenanordnung 27 ist eine Spannwalzenanordnung 28 zum Gespannthalten zweiter Materialbahnen 22; 29 zugeordnet, die von einer (nicht gezeigten) Schneideinrichtung parallel zugeführt werden. Die Materialbahn 22 wird über die Wendestangenanordnung 27 zu einer ersten Umlenkwalze 31 geführt, die zweite Materialbahn 29 geht von der Spannwalzenanordnung 28 direkt zu einer Umlenkwalze 32. Mit Hilfe der Wendestangenanordnung 27 wird der seitliche Versatz zwischen den zwei Materialbahnen 22; 29 ausgeglichen, so dass diese mit exakt überlappenden Rändern und, durch geeignete Einstellung der Position der Registerwalze 14, auch in Phase miteinander einem (nicht gezeigten) Falzapparat zum Falzen und Schneiden zugeführt werden können.Fig. 3 shows a highly schematic of a stack in which a plurality of turning bar assemblies 27 of the type shown in Figs. 1 and 2 are arranged one above the other, as seen from the direction of the arrow IV in Fig. 1. The stack here comprises four superimposed turner bar assemblies 27, their Number can also be larger or smaller. Each turner bar assembly 27 is a tension roller assembly 28 for holding second web webs 22; 29, which are fed in parallel by a cutter (not shown). The material web 22 is guided via the turning bar assembly 27 to a first guide roller 31, the second web 29 goes from the tension roller assembly 28 directly to a guide roller 32. With the help of the turning bar assembly 27, the lateral offset between the two webs material 22; 29 balanced, so that they can be fed with exactly overlapping edges and, by suitable adjustment of the position of the register roller 14, also in phase with each other (not shown) folder for folding and cutting.

Fig. 4 zeigt eine zweite Ausgestaltung der Wendestangenanordnung, gesehen in der gleichen Perspektive wie in Fig. 2. Bei der Ausgestaltung der Fig. 4 wird der einlaufende Abschnitt 23 der Materialbahn 22 an die Unterseite der zweiten Wendestange 06 herangeführt, umschlingt diese von unten nach oben, umrundet dann von oben nach unten eine Umlenkwalze 33, die die Umlenkwalzenanordnung 16 aus Fig. 2 ersetzt, erreicht die in Richtung des Pfeils P verschiebbare Registerwalze 14 und verläuft von dort an wie mit Bezug auf Fig. 2 beschrieben. Der Höhenunterschied zwischen einlaufendem und auslaufendem Abschnitt 23 bzw. 24 ist bei dieser Variante minimal.4 shows a second embodiment of the turning bar arrangement, seen in the same perspective as in FIG. 2. In the embodiment of FIG. 4, the incoming section 23 of the material web 22 is brought to the underside of the second turning bar 06, wraps it around from below above, then rounds from top to bottom a guide roller 33, which replaces the guide roller assembly 16 of FIG. 2, reaches the displaceable in the direction of the arrow P register roller 14 and extends therefrom as described with reference to FIG. The height difference between incoming and outgoing section 23 and 24 is minimal in this variant.

Fig. 5 zeigt eine Ansicht einer dritten Ausgestaltung der Wendestangenordnung in einer Perspektive analog der der Fig. 2 und 4. Wie bereits bei der zweiten Ausgestaltung der Fig. 4 sind hier Elemente, die Elementen der ersten Ausgestaltung entsprechen und mit Bezug auf Fig. 1 und 2 bereits beschrieben sind, mit gleichem Bezugszeichen bezeichnet und nicht erneut beschrieben. Bei dieser dritten Ausgestaltung ist die Bauhöhe der Wendestangenanordnung weiter reduziert, indem beide Wendestangen 06; 07 in einer gleichen Ebene E angeordnet sind. Einlaufender und auslaufender Abschnitt 23; 24 befinden sich auf gleichem Niveau. Die (in der Fig. 5 nicht sichtbaren) Träger 03; 04 sind an einem einzigen Führungsprofil 02 montiert. Während bei den zwei zuvor beschriebenen Varianten die zwei Wendestangen 06; 07 beliebig nahe aneinander herangerückt werden können und sogar übereinander hinweg verschoben werden können, ist dies bei der Variante der Fig. 5 nicht möglich. Eine wesentliche Einschränkung in der Brauchbarkeit ist damit jedoch nicht verbunden, da Materialbahnen 22, die mit Hilfe der Wendestangenanordnung übereinandergelegt werden sollen, in den meisten Fällen aus einer einheitlichen Bahn durch Längsschneiden erhaltene Teilbahnen sind, die, um sie übereinander legen zu können, um wenigstens ihre eigene Breite verschoben werden müssen. Der hierfür erforderliche Abstand der Wendestangen 06; 07 kann auch bei dieser dritten Ausgestaltung leicht eingestellt werden. Um die Ausgestaltung der Fig. 5 zum Parallelverschieben einer Bahn wahlweise in entgegengesetzte Richtungen gebrauchen zu können, genügt es, dass beide Wendestangen 06; 07 so wie mit Bezug auf Fig. 1 für die zweite Wendestange 06 beschrieben, umstellbar sind, so dass die Wendestangenanordnung in ihr Spiegelbild überführbar ist.5 shows a view of a third embodiment of the turning bar arrangement in a perspective analogous to that of FIGS. 2 and 4. As in the second embodiment of FIG. 4, elements corresponding to elements of the first embodiment are here, and with reference to FIG and 2 already described, designated by the same reference numeral and not described again. In this third embodiment, the height of the turning bar assembly is further reduced by both turning bars 06; 07 are arranged in a same plane E. Inlet and outlet section 23; 24 are at the same level. The carrier (not visible in FIG. 5) 03; 04 are mounted on a single guide profile 02. While in the two variants described above, the two turning bars 06; 07 can be moved as close as possible to each other and even can be moved over each other away, this is not possible in the variant of FIG. 5. However, a substantial limitation in the usability is not associated therewith, since webs of material 22 which are to be superimposed by means of the turning bar arrangement are in most cases part webs obtained from a unitary web by longitudinal cutting and, in order to be able to lay them over one another, at least their own width must be moved. The required distance of the turning bars 06; 07 can also be easily adjusted in this third embodiment. In order to use the embodiment of FIG. 5 for parallel displacement of a web optionally in opposite directions, it is sufficient that both turning bars 06; 07 as with reference to FIG. 1 for described the second turning bar 06, are reversible, so that the turning bar assembly can be converted into its mirror image.

Alle Wendestangen 06; 07, Umlenkstangen 16; 33 und die Registerwalzen 14 sind vorzugsweise als Kragarm ausgebildet, d. h. lediglich ein Ende ist gelagert.All turner bars 06; 07, deflection rods 16; 33 and the register rollers 14 are preferably formed as a cantilever, ie only one end is mounted.
