Description

Die Erfindung betrifft eine Vorrichtung zum Spreizen von Bahnsträngen in einer oder für eine Bahnbearbeitungsmaschine, insbesondere Druckmaschine. Die Maschine ist vorzugsweise eine Rollenrotationsdruckmaschine, bevorzugt für den Offsetdruck, insbesondere Nassoffset. Es kann sich um eine Akzidenzdruckmaschine oder, bevorzugter um eine Zeitungsdruckmaschine für große Auflagen handeln.The invention relates to a device for spreading web strands in or for a web-processing machine, in particular printing press. The machine is preferably a web-fed rotary printing press, preferably for offset printing, in particular wet offset. It may be a commercial press or, more preferably, a large format newspaper press.

Vorrichtungen zum Spreizen von Bahnsträngen sind beispielsweise aus der DE 103 37 248 A1 und der DE 100 23 169 A1 bekannt. Die bekannten Vorrichtungen sind auf die Verwendung in Druckmaschinen für einen maximal vier-seiten-breiten Zeitungsdruck beschränkt.Devices for spreading web strands are for example from DE 103 37 248 A1 and the DE 100 23 169 A1 known. The known devices are limited to use in printing machines for a maximum of four pages wide newspaper printing.

Die DE 87 17 253 U1 beschreibt eine Vorrichtung zum Umlenken und seitlichen Auslenken verschiedener aus einer Materialbahn, beispielsweise einer Papierbahn, durch Längsschnitt erzeugten Streifen. Die Vorrichtung ist so konzipiert, dass sie für unterschiedliche Bahnmaterialien und/oder -breiten geeignet ist. Aus der WO 00/06478 ist eine Vorrichtung zum Trennen von laminierten Polymerfilmbahnen bekannt, mit der eine durch Dehnung erzeugte Verbreiterung der Bahnen kompensiert werden kann. Als nächstkommender Stand der Technik wird das Dokument DE 198 23 255 A1 angesehen. Dieses Dokument beschreibt eine Anlage zur breitenvariablen Fertigung von veredelten Bahnwaren, in der Materialbahnen in beweglich angeordneten Trenneinrichtungen beschnitten und über beweglich angeordnete Umlenkeinrichtungen in ihrer Laufrichtung umgelenkt werden können.The DE 87 17 253 U1 describes a device for deflecting and laterally deflecting various strips produced from a material web, for example a paper web, by longitudinal cutting. The device is designed to be suitable for different web materials and / or widths. From the WO 00/06478 An apparatus for separating laminated polymer film webs is known, with which an expansion of the webs produced by stretching can be compensated. The closest prior art is the document DE 198 23 255 A1 considered. This document describes a plant for variable-width production of finished web goods, can be cut in the webs of material in movably arranged separating devices and deflected over movably arranged deflection in their direction of travel.

Es ist eine Aufgabe der Erfindung, das Spreizen auch von längs geschnittenen Bahnen größerer Breite zu ermöglichen.It is an object of the invention to allow the spreading of longitudinally cut webs of greater width.

Eine erfindungsgemäße Vorrichtung zum Spreizen von Bahnsträngen, im folgenden Bahnspreizvorrichtung, umfasst Schneideinrichtungen zum Längsschneiden einer Bahn wenigstens in einer linken, einen rechten und einen mittleren Bahnstrang sowie ferner eine linke Umlenkeinrichtung für den linken Bahnstrang, eine rechte Umlenkeinrichtung für den rechten Bahnstrang und eine mittlere Umlenkeinrichtung für den mittleren Bahnstrang. Die Umlenkeinrichtungen umfassen je wenigstens zwei Umlenkmittel, von denen jedes eine Umlenkachse für einen der Bahnstränge bildet. Bei eingezogener Bahn werden nach dem Längsschneiden die Bahnstränge über die wenigstens zwei zugeordneten Umlenkmittel geführt, umschlingen diese Umlenkmittel nacheinander und werden auf diese Weise umgelenkt. Um die unmittelbar nach dem Längsschneiden längs ihrer Seitenränder aneinander stoBenden Bahnstränge voneinander abzuspreizen, d.h. parallel zueinander zu versetzen, weisen die Umlenkachsen von wenigstens zwei der Undenkeinrichtungen zu der Förderrichtung des jeweils zugeordneten Bahnstrangs und auch relativ zu der Förderrichtung des verbleibenden weiteren Bahnstrangs in einer Draufsicht auf den jeweiligen Bahnstrang unmittelbar vor dem Einlaufen in die zugeordnete Umlenkeinrichtung gesehen, jeweils eine Neigung auf. Die um die geneigten Umlenkachsen umgelenkten Bahnstränge sind nach dem zweifachen Umlenken parallel zu sich selbst, bezogen auf die Position des jeweiligen Bahnstrangs vor dem Umlenken, und auch zu dem wenigstens einen weiteren Bahnstrang versetzt. Die Neigung der Umlenkachsen ist vorzugsweise so gewählt, dass die wenigstens zwei parallel versetzten Bahnstränge von dem wenigstens einen weiteren Bahnstrang und, sollten sie nächstbenachbart sein, auch voneinander einen Abstand aufweisen. Die Umlenkachsen für den einen und die Umlenkachsen für den wenigstens einen weiteren parallel zu versetzenden Bahnstrang können in Bezug auf die Förderrichtung der einlaufenden Bahnstränge zur gleichen Seite und nur mit unterschiedlich großen Winkeln geneigt sein, so dass die Bahnstränge mit unterschiedlich großem Versatz, aber zur gleichen Seite hin versetzt werden. Bevorzugter weisen die Neigungswinkel bezogen auf die Förderrichtung jeder unterschiedliche Vorzeichen auf, so dass einer der Bahnstränge nach links und der wenigstens eine andere Bahnstrang nach rechts versetzt wird, wobei der Versatz der Bahnstränge unterschiedlich oder vorzugsweise gleich ist.A device according to the invention for spreading web strands, in the following web spreading device, comprises cutting devices for longitudinal cutting of a web at least in a left, a right and a middle web strand and also a left deflection for the left web strand, a right deflection for the right web strand and a middle deflection for the middle track. The deflection devices each comprise at least two deflection means, each of which forms a deflection axis for one of the web strands. When the web is retracted, after the longitudinal cutting, the web strands are guided over the at least two associated deflecting means, these deflecting means loop around one after the other and are deflected in this way. In order to spread apart the web strands abutting one another along their side edges immediately after the longitudinal cutting, ie to offset them parallel to one another, the deflection axes of at least two of the unconveying devices point to the conveying direction of the respective associated web strand and also relative to the conveying direction of the remaining further web strand seen in a plan view of the respective web strand immediately before entering the associated deflection, in each case an inclination. The web strands deflected about the inclined deflecting axes are offset parallel to themselves after the double deflecting, relative to the position of the respective web strand before deflecting, and also to the at least one further web strand. The inclination of the deflection axes is preferably selected so that the at least two parallel offset web strands of the at least one further web strand and, should they be next to each other, also have a distance from each other. The deflection axes for the one and the deflection axes for the at least one further web strand to be offset in parallel can be inclined with respect to the conveying direction of the incoming web strands to the same side and only with different sized angles, so that the web strands with different sized offset, but at the same Be offset side. More preferably, the inclination angles with respect to the conveying direction each have different signs, so that one of the web strands is shifted to the left and the at least one other web strand is shifted to the right, the offset of the web strands being different or preferably the same.

Die erfindungsgemäße Bahnspreizvorrichtung ist insbesondere für den Einsatz in einer sechs-seiten-breiten Druckmaschine geeignet, um drei jeweils zwei-seiten-breite Bahnstränge voneinander abzuspreizen und mittig auf jeweils einen Längsfalztrichter zu fördern. Auf diese Weise können die Trichter je in einer festen Position für den Druck auf eine Bahn maximaler Breite angeordnet sein. Mittels der Bahnspreizvorrichtung können ohne Änderung der Positionen der Trichter auch sechs-seiten-breite Bahnen bedruckt werden, die schmaler als die maximale Breite sind, indem derartige Bahnen längs geschnitten und die Bahnstränge auf die Trichter mittig gespreizt werden. Andererseits ist die Erfindung nicht auf das Spreizen von gleichbreiten Bahnsträngen beschränkt. So können beispielsweise auch Bahnen verarbeitet werden, die fünf-seiten-breit sind und in zwei zwei-seiten-breite Bahnstränge und einen ein-seiten-breiten Bahnstrang längs geschnitten werden. Grundsätzlich können auch noch schmalere Bahnen verarbeitet werden, beispielsweise drei-seiten-breite Bahnen, die in drei jeweils ein-seiten-breite Bahnstränge, im folgenden Teilstränge, längs geschnitten und durch das Spreizen in Bezug auf die Trichter positioniert werden. Die genannten Beispiele verdeutlichen den Zugewinn an Flexibilität hinsichtlich der Konfigurierung, beschränken die Erfindung jedoch nicht auf die genannten Bahn- und Teilstrangbreiten. Mittels der erfindungsgemäßen Bahnspreizvorrichtung können wenigstens drei Teilstränge in Bezug auf die Trichter positioniert werden, während die Trichter nicht verstellt werden müssen und in bevorzugten einfachen Ausführungen auch quer zur Förderrichtung der auf die Trichter laufenden Teilstränge nicht verstellbar, sondern unbeweglich montiert sind. Andererseits kann die Bahnspreizvorrichtung jedoch auch vorteilhaft mit quer zur Förderrichtung seitlich verstellbaren Trichtern kombiniert werden, um die Flexibilität noch zu steigern.The web spreading device according to the invention is particularly suitable for use in a six-page-wide printing press to spread apart three web strands, each two-sided wide, and to convey them centrally to one longitudinal folding hopper each. In this way, the funnels can each be arranged in a fixed position for printing on a web of maximum width. By means of the web spreading device can be printed without changing the positions of the funnels also six-page-wide webs that are narrower than the maximum width by longitudinally cut such webs and the web strands are spread in the middle of the funnels. On the other hand, the invention is not limited to the spreading of uniform web strands. For example, webs that are five-sided wide and longitudinally cut into two two-page-wide web cords and one-page-wide web cords can also be processed. In principle, even narrower webs can be processed, for example, three-side-wide webs, which are cut longitudinally into three webs, each one-side-wide, in the following sub-strands, and positioned by spreading with respect to the funnels. The examples given illustrate the gain in flexibility with regard to the configuration, but do not limit the invention to the aforementioned web and sub-strand widths. By means of the invention Web spreading device can be positioned at least three sub-strands with respect to the funnels, while the funnels do not need to be adjusted and in preferred simple embodiments also transversely to the conveying direction of the funnels running partial strands not adjustable, but are immovably mounted. On the other hand, however, the web spreading device can also advantageously be combined with funnels which can be laterally adjusted transversely to the conveying direction in order to increase the flexibility even further.

Solch eine Art der Bewegbarkeit ermöglicht die Verarbeitung von Bahnen unterschiedlicher Breite, indem die Umlenkeinrichtung oder die mehreren Umlenkeinrichtungen in Anpassung an unterschiedliche Breiten verstellt wird oder werden. Wenigstens eine Längsschneideinrichtungen ist im gleichen Sinne verstellbar, wenigstens eine der Längsschneideinrichtungen ist mit einer quer verstellbaren Umlenkeinrichtung mechanisch gekoppelt. Die mechanische Kopplung ist derart, dass eine Querverstellung der jeweilige Umlenkeinrichtung eine Querverstellung der jeweils zugeordneten Längsschneideinrichtung um das gleiche Maß bewirkt.According to the invention, at least one of the deflecting devices, more preferably two or even more of the deflecting devices, are arranged to be movable in the transverse direction to the respectively assigned sub-strand, viewed in a plan view of the sub-strand entering the respective deflecting device immediately before looping around an inclined first deflecting means respective deflection. Such a kind of mobility allows the processing of webs of different widths by adjusting the baffle or the plurality of baffles in adaptation to different widths. At least one longitudinal cutting device is adjustable in the same sense, at least one of the longitudinal cutting devices is mechanically coupled to a transversely adjustable deflection device. The mechanical coupling is such that a transverse adjustment of the respective deflection device causes a transverse adjustment of the respectively associated longitudinal cutting device by the same amount.

In bevorzugten Ausführungen ist wenigstens bei einer der Umlenkeinrichtungen wenigstens eines ihrer Umlenkmittel quer zur Förderrichtung eines zugeordneten Teilstrangs längenverstellbar. Vorzugsweise ist wenigstens ein Umlenkmittel der mittleren Umlenkeinrichtung längenverstellbar. In einer ersten Variante ist nur eines der Umlenkmittel der betreffenden Umlenkeinrichtung längenverstellbar. In einer zweiten Variante sind mehrere der Umlenkmittel oder alle Umlenkmittel der betreffenden Umlenkeinrichtung längenverstellbar. Das oder die weitere(n) Umlenkmittel der wenigstens einen langenverstellbaren Umlenkeinrichtung ist oder sind in der ersten Variante vorzugsweise so lang, dass es oder sie den umschlingenden Teilstrang über dessen gesamte Breite stützt oder stützen. Das oder die weitere(n) Umlenkmittel der längenverstellbaren Umlenkeinrichtung kann oder können sich über die gesamte Breite der Bahnspreizvorrichtung erstrecken. Das oder die längenverstellbare(n) Umienkmittel ist oder sind vorteilhafterweise mechanisch mit wenigstens einer der Schneideinrichtungen oder der bzw. den quer verstellbare(n) anderen Umlenkeinrichtung(en) mechanisch gekoppelt, so dass bei einer Querverstellung einer Längsschneideinrichtung oder Umlenkeinrichtung synchron im gleichen Ausmaß auch die Länge(n) des oder der längenverstellbaren Umlenkmittel(s) verstellt wird oder werden. Das Wort "oder" wird hier und auch sonst im Sinne von "und/oder" verstanden, enthält also stets die Bedeutung von "entweder ........... oder" und auch die weitere Bedeutung von "und", soweit sich aus dem jeweiligen Zusammenhang nicht zwangsläufig etwas anderes nur ergeben kann.In preferred embodiments, at least one of its deflection means is adjustable in length transversely to the conveying direction of an associated sub-strand at least in one of the deflection devices. Preferably, at least one deflection means of the central deflection device is adjustable in length. In a first variant, only one of the deflection of the respective deflection is adjustable in length. In a second variant, a plurality of the deflection means or all deflection means of the respective deflection device are adjustable in length. The one or more further deflecting means of the at least one longitudinally adjustable deflecting device is or are preferably so long in the first variant that it supports the supporting partial strand over its entire width. The one or more further deflection means of the length-adjustable deflection device can or can extend over the entire width of the web spreading device. The length-adjustable or circumferential adjusting means or is advantageously mechanical with at least one of the cutting devices or the transversely adjustable other deflection device (s) is mechanically coupled, so that in a transverse displacement of a longitudinal cutting device or deflection synchronously to the same extent and the length (n) of the length-adjustable deflection means (s) is adjusted or become. The word "or" is understood here and elsewhere in the sense of "and / or", thus always contains the meaning of "either ........... or" and also the further meaning of "and" as far as something else can not necessarily result from the respective context.

Es müssen nicht sämtliche Teilstränge parallel zu sich selbst versetzt werden, obgleich eine entsprechende Bahnspreizvorrichtung auch ein Gegenstand der Erfindung ist. Bei beispielsweise drei Teilsträngen genügt es, wenn nur zwei dieser Teilstränge versetzt und der dritte ohne Versatz durch die Bahnspreizvorrichtung geführt werden. So können beispielsweise der mittlere Teilstrang ohne Versatz durch die Bahnspreizvorrichtung gefördert und der linke Teilstrang nach links und der rechte Teilstrang nach rechts von dem mittleren Teilstrang weg gespreizt werden. Der nicht versetzte Teilstrang wird vorzugsweise mittels der zugeordneten Umlenkeinrichtung so geführt, dass er die gleiche Weglänge wie die parallel zu sich selbst versetzten, d.h. abgespreizten Teilstränge zurücklegt. Die betreffende Umlenkeinrichtung dient als Bahnlängenkompensator. Von Vorteil ist, wenn der nicht gespreizte Teilstrang so umgelenkt wird, dass auf ihn zumindest im Wesentlichen die gleichen Reibungskräfte wie auf die umgelenkten Teilstränge wirken. Besonders vorteilhaft ist in derartigen Ausführungen, wenn die Umlenkeinrichtungen, zu denen auch der Bahnlängenkompensator zählt, jeweils gleich viele Umlenkmittel und entsprechend Umlenkachsen umfassen und die Teilstränge nicht nur in der Summe die gleiche Gesamtumschlingung erfahren, sondern auch die Umschlingungswinkel untereinander gleich sind, beispielsweise indem das bei jeder der Umlenkeinrichtungen erste Umlenkmittel mit gleichem Umschlingungswinkel und auch das wenigstens eine weitere zweite Umlenkmittel jeweils mit dem gleichen Umschlingungswinkel umschlungen wird. Falls einer der Teilstränge nicht versetzt wird, ist dessen zugeordnete Umlenkeinrichtung, der Bahnlängenkompensator, vorzugsweise so ausgebildet, dass sie sowohl die Weglänge für den betreffenden Teilstrang an die Weglängen der anderen Teilsträngen angleicht als auch deren Umschlingungswinkel nachbildet. Vorteilhaft ist, wenn diese Umlenkeinrichtung die längenverstellbare Umlenkeinrichtung ist.Not all partial strands need to be offset parallel to themselves, although a corresponding web spreading device is also an object of the invention. In the case of, for example, three partial strands, it is sufficient if only two of these partial strands are displaced and the third is guided without offset through the web spreading device. For example, the middle sub-strand can be conveyed without offset through the web spreading device, and the left sub-strand can be spread to the left and the right sub-strand can be spread to the right away from the middle sub-strand. The non-staggered sub-string is preferably guided by means of the associated deflection so that it covers the same path length as the parallel to itself offset, ie splayed partial strands. The respective deflection device serves as a web length compensator. It is advantageous if the non-spread partial strand is deflected so that act on him at least substantially the same frictional forces as on the deflected partial strands. Particularly advantageous in such embodiments, when the deflection, which also includes the Bahnlängenkompensator, each comprise the same number of deflection and corresponding deflection axes and the sub-strands experience not only the sum of the same Gesamtumschlingung, but also the wrap angles are equal to each other, for example by the in each of the deflection devices, first deflection means with the same wrap angle and also the at least one further second deflection means are each looped around with the same wrap angle. If one of the partial strands is not displaced, its associated deflection device, the path length compensator, is preferably designed such that it both aligns the path length for the relevant partial strand with the path lengths of the other partial strands and also simulates its wrap angle. It is advantageous if this deflection device is the length-adjustable deflection device.

Die Bahnspreizvorrichtung kann erst hinter einem Druckwerk oder mehreren die Teilstränge nacheinander bedruckenden Druckwerken angeordnet sein, d.h. zwischen dem Druckwerk oder den mehreren Druckwerken einerseits und einer Wendeeinrichtung und nachfolgenden Trichtern andererseits. Die Schneideinrichtungen können vor dem oder den Druckwerk(en) angeordnet sein oder bevorzugt dahinter und bevorzugt unmittelbar vor den Umlenkeinrichtungen der Spreizvorrichtung. In einer ebenfalls bevorzugten Alternative ist die Bahnspreizvorrichtung vor einem ersten Druckwerk angeordnet, in dem einer, mehrere oder alle der durch die Bahnspreizvorrichtung geführten Teilstränge bedruckt wird oder werden. Der Längsschnitt breiter Bahnen in mehrere Teilstränge vor dem Druck eröffnet neue Möglichkeiten den sogenannten Fan-Out-Effekt im Druckwerk zu beherrschen, da die mit einer Feuchteaufnahme und der Längsspannung einhergehenden Änderungen der Breite bei schmaleren Teilsträngen auf einfachere Weise als bei einer breiteren Gesamtbahn kompensiert werden können. Ist die Bahnbearbeitungsmaschine eine Rollendruckmaschine, ist die Bahnspreizvorrichtung in derartigen Ausführungen zwischen einem Rollenwechsler, von dem die Bahn abwickelt, und dem im Bahnweg ersten Druckwerk angeordnet.The web spreading device can be arranged only behind a printing unit or a plurality of the sub strands successive printing units, i. between the printing unit or the plurality of printing units on the one hand and a turning device and subsequent funnels on the other. The cutting devices can be arranged in front of the printing unit (s) or preferably behind it and preferably directly in front of the deflection devices of the spreading device. In a likewise preferred alternative, the web spreading device is arranged in front of a first printing unit in which one, several or all of the partial strands guided by the web spreading device are or will be printed. The longitudinal section of wide webs in several sub-strands before printing opens up new opportunities to dominate the so-called fan-out effect in the printing unit, since the changes associated with a moisture absorption and the longitudinal tension changes in narrow strands are compensated in a simpler manner than in a wider total track can. If the web-processing machine is a web-fed printing press, the web spreading device in such embodiments is arranged between a reel splicer from which the web unwinds and the first printing press in the web path.

Falls einer der Teilstränge wie bereits erwähnt nicht versetzt wird, aber dennoch wie bevorzugt eine Längenkompensation für den betreffenden Teilstrang vorgenommen wird, kann die den Bahnlängenkompensator bildende Umlenkeinrichtung vor oder bevorzugter im Bahnweg hinter den Umlenkeinrichtungen für die anderen Teilstränge angeordnet sein. In einer ebenfalls bevorzugten Alternative ist die Umlenkeinrichtung für den nicht zu versetzenden Teilstrang in Förderrichtung zumindest im Wesentlichen auf gleicher Höhe neben oder vorzugsweise zwischen anderen Umlenkeinrichtungen der Bahnspreizvorrichtung angeordnet. Dies gestattet eine besonders kompakte Bauweise, so dass eine derartige Bahnspreizvorrichtung nur wenig Platz in der Maschine beansprucht und das Spreizen der Teilsträngen sowie die bevorzugte Längenkompensation innerhalb einer kurzen Bahnlänge durchgeführt werden kann.If one of the sub-strands is not displaced as already mentioned, but nevertheless a length compensation for the relevant sub-strand is made as preferred, the deflection device forming the web length compensator can be arranged before or more preferably in the web path behind the deflection devices for the other sub-strands. In a likewise preferred alternative, the deflection device for the non-displaceable sub-strand is arranged in the conveying direction at least substantially at the same height beside or preferably between other deflection devices of the web spreading device. This allows a particularly compact design, so that such a web spreading claimed only little space in the machine and the spreading of the strands and the preferred length compensation can be performed within a short track length.

Für das Spreizen und die optionale Längenkompensation sind die hierfür jeweils vorgesehenen Umlenkeinrichtungen in Bezug auf die Ebene des jeweils zugeordneten Teilstrangs heb- und senkbar gelagert. Hub- und Senkmechanismen für die wenigstens drei Umlenkeinrichtungen können je eine Linearführung und einen Antrieb für die Heb- und Senkbewegungen der Umlenkeinrichtungen umfassen, vorzugsweise je eine eigene Linearführung und je einen eigenen Antrieb pro Umlenkeinrichtung. Die Antriebe können insbesondere je eine in Heb- und Senkrichtung erstreckte Spindel, einen Drehantrieb für die Spindeln und ein Spindelgegenglied pro Spindel umfassen, wobei die Spindeln mit dem jeweils zugeordneten Spindelgegenglied in einem Gewindeeingriff sind und das jeweilige Gegenglied linear geführt ist, so dass Drehbewegungen der Spindel eine entsprechende lineare Hebe- oder Senkbewegung des jeweiligen Spindelgegenglieds bewirken. Derartige Hub- und Senkmechanismen sind insbesondere für die linke und die rechte Umlenkeinrichtung von Vorteil. Für die mittlere Umlenkeinrichtung ist ein Hub- und Senkmechanismus vorteilhaft, der ein Gestänge mit wenigstens zwei Achsen und je Achse wenigstens zwei schwenkbaren Gestängearmen umfasst, wobei pro Achse je einer der Gestängearme gelenkig mit dem Gestell der Bahnbearbeitungsmaschine und der andere Gestängearm gelenkig mit einem Träger verbunden ist. An dem Träger ist eines der Umlenkmittel oder sind vorzugsweise zwei, gegebenenfalls auch noch mehr Umlenkmittel angeordnet, um das oder die der zugeordnete Teilstrang umgelenkt wird. Der Hub- und Senkmechanismus umfasst desweiteren ein Koppelglied, das die wenigstens zwei Achsen mechanisch miteinander koppelt. Das Koppelglied kann insbesondere eine Spindel sein, die mit jeder der beiden Achsen in einem Gewindeeingriff ist. Schließlich umfasst der Hub- und Senkmechanismus einen Antrieb, vorzugsweise ein Elektromotor, der vorteilhafterweise das Koppelglied antreibt und sich in derartigen Ausführungen an beispielsweise einer der Achsen abstützen kann. Die Gestängearme spreizen sich bei der Heb- und Senkbewegung scherenartig auseinander oder aufeinander zu und verringern so den Abstand zwischen dem Träger und der gelenkigen Verbindung mit dem Gestell.For the spreading and the optional length compensation, the respectively provided for this deflection devices are mounted in relation to the level of each associated sub-strand raised and lowered. Lifting and lowering mechanisms for the at least three deflection devices can each have a linear guide and a drive for the lifting and lowering movements the deflection devices, preferably each have their own linear guide and its own drive per deflection. The drives can in particular each comprise a spindle extending in the raising and lowering direction, a rotary drive for the spindles and a spindle counterpart per spindle, wherein the spindles are in threaded engagement with the respective associated spindle counterpart and the respective counter member is linearly guided, so that rotational movements of the Spindle cause a corresponding linear lifting or lowering movement of the respective spindle counter member. Such lifting and lowering mechanisms are particularly advantageous for the left and the right deflection. For the middle deflection, a lifting and lowering mechanism is advantageous, comprising a linkage with at least two axes and each axis at least two pivotable link arms, wherein per axis each one of the link arms hingedly connected to the frame of the web processing machine and the other linkage arm articulated to a carrier is. On the support is one of the deflection or are preferably two, possibly even more deflection arranged, around which or the associated sub-strand is deflected. The lifting and lowering mechanism further comprises a coupling member which mechanically couples the at least two axes. The coupling member may in particular be a spindle which is in threaded engagement with each of the two axes. Finally, the lifting and lowering mechanism comprises a drive, preferably an electric motor, which advantageously drives the coupling member and can be supported in such embodiments on, for example, one of the axles. The linkage arms spread apart like scissors during the raising and lowering movement and thus reduce the distance between the carrier and the articulated connection with the frame.

Figur 1 zeigt Komponenten einer Rollenrotationsdruckmaschine, die eine Bahnspreizvorrichtung nach der Erfindung umfasst. Dargestellt ist der Weg einer zu bedruckenden Bahn P, der von einem Rollenwechsler 1 über die Bahnspreizvorrichtung zu einem Druckturm 20 führt. Zu der Bahnspreizvorrichtung gehören eine linke und eine rechte Längsschneideinrichtung 4, die dazu dienen, die Bahn P längs in drei Bahnstränge bzw. Teilstränge T zu schneiden, und Umlenkeinrichtungen 5 und 6, mittels denen die Teilstränge T parallel voneinander abgespreizt werden können. Die abgespreizten Bahnstränge T werden in Förderrichtung F zu dem Druckturm 20 gefördert und dort je beidseitig mehrfarbig bedruckt. Im Druckturm 20 sind mehrere Druckwerke vertikal übereinander angeordnet. Die Druckwerke umfassen je zwei einen Druckspalt für beidseitigen Druck bildende Druckzylinder 24, den Druckzylindern 24 zugeordnete Druckformzylinder sowie zugeordnete Farb- und Feuchtwerke für den Nassoffsetdruck. Hinter dem Druckturm 20 werden die Teilstränge T entweder getrennt je allein oder je mit wenigstens einem weiteren Bahnstrang auf Falztrichter 21, 22 und 23 oder auf einen gemeinsamen Falztrichter geführt und mittels der Falztrichter getrennt oder mittels eines gemeinsamen Falztrichters gemeinsam längs gefalzt. Hinter dem Falztrichter oder den mehreren Falztrichtern 21, 22 und 23 kann in Förderrichtung F ein Falzapparat oder können mehrere Falzapparate zum Querschneiden und Querfalzen angeordnet sein. FIG. 1 shows components of a web-fed rotary printing press comprising a web spreading device according to the invention. Shown is the path of a web P to be printed, which leads from a roll changer 1 via the web spreading device to a printing tower 20. The web spreading device includes left and right longitudinal cutters 4 which serve to cut the web P longitudinally into three web strands T and diverters 5 and 6 by means of which the sub strands T can be spread apart in parallel. The splayed web strands T are conveyed in the conveying direction F to the printing tower 20 and printed on both sides depending on multi-colored. In the printing tower 20, several printing units are arranged vertically one above the other. The printing units each comprise two printing cylinders 24 forming a printing nip for double-sided printing, the printing cylinder cylinders 24 assigned printing form cylinders and associated inking and dampening units for the wet offset printing. Behind the printing tower 20, the sub strands T are either separately or ever with at least one other web strand fed on formers 21, 22 and 23 or on a common former and separated by means of the former or folded together along a common former. Behind the former or the plurality of formers 21, 22 and 23 can be arranged in the conveying direction F, a folder or multiple folders for cross cutting and Querfalzen.

Die von dem Rollenwechsler 1 in die Bahnspreizvorrichtung einlaufende Bahn P wird über eine Einlauf-Leiteinrichtung 3 zu den Längsschneideinrichtungen 4 gefördert. Die Längsschneideinrichtungen 4 weisen pro Längsschnitt zwei aufeinander zu- und voneinander abstellbare Schneidmesser auf, zwischen denen die Bahn P hindurchgefördert wird. Die durch den Längsschnitt erhaltenen Teilstränge T laufen dicht nebeneinander bis zu einer linken Umlenkeinrichtung für den linken Teilstrang und einer rechten Umlenkeinrichtung für den rechten Teilstrang. Die linke und die rechte Umlenkeinrichtung umfassen je ein erstes Umlenkmittel 5, ein unmittel folgendes zweites Umlenkmittel 6 und ein dem zweiten Umlenkmittel 6 unmittelbar in Bahnweg folgendes drittes Umlenkmittel 7. Der linke und der rechte Teilstrang umschlingen die Umlenkmittel 5, 6 und 7 der jeweils zugeordneten Umlenkeinrichtung. Der mittlere Teilstrang wird zwischen den Umlenkeinrichtungen 5, 6, 7 gerade und von diesen unbeeinflusst weitergefördert bis zu einem Bahnlängenkompensator 25a-c. Die Umlenkmittel 5 und 6 weisen in einer Draufsicht auf die auf die Umlenkmittel 5 auflaufenden äußeren Teilstränge T mit einer Neigung zu der Förderrichtung F dieser Teilstränge T. Die Umlenkmittel 6 sind zu den Umlenkmitteln 5 parallel, so dass die beiden äußeren Teilstränge T parallel zu sich selbst und von dem mittleren Teilstrang T weg jeweils nach außen versetzt und in diesem Sinne abgespreizt werden. Die Umlenkmittel 7 hingegen weisen exakt senkrecht zu der Förderrichtung F des jeweils auflaufenden Teilstrangs T. Der mittlere Teilstrang T wird ohne Versatz durch die Bahnspreizvorrichtung gefördert. Er wird von den Schneideinrichtungen 4 unmittelbar zum Bahnlängenkompensator 25a-c geführt, der ein erstes Umlenkmittel 25a, ein zweites Umlenkmittel 25b und ein drittes Umlenkmittel 25c umfasst, um die der mittlere Teilstrang T jeweils umgelenkt wird. Alle drei Teilstränge T werden hinter der jeweils dritten Umlenkeinrichtung 7 oder 25c über eine Auslauf-Leiteinrichtung 8 geführt. Die drei Teilstränge T umschlingen gemeinsam die Auslauf-Leiteinrichtung 8 und werden von dort über ein Vorspannwerk 19 in und durch den Druckturm 20 und schließlich über den Trichter oder die mehreren Trichter 21, 22 und 23 gefördert.The incoming from the roll changer 1 in the web spreading device web P is conveyed via an inlet guide 3 to the longitudinal cutting devices 4. The longitudinal cutting devices 4 have, per longitudinal section, two cutting blades which can be put on and off one another and between which the web P is conveyed through. The partial strands T obtained by the longitudinal section run close to each other up to a left deflection device for the left partial strand and a right deflection device for the right partial strand. The left and the right deflection device each comprise a first deflection means 5, an immediately following second deflection means 6 and a third deflection means 7 following the second deflection means 6 directly in the track. The left and the right sub-string wrap around the deflection means 5, 6 and 7 of the respective associated ones deflection. The middle sub-string is conveyed straight between the deflection devices 5, 6, 7 and unaffected by these until a track length compensator 25a-c. The deflection means 5 and 6 have, in a plan view, the outer partial strands T running onto the deflection means 5 with an inclination to the conveying direction F of these partial strands T. The deflection means 6 are parallel to the deflection means 5, so that the two outer partial strands T are parallel to one another itself and offset from the middle sub-strand T away to the outside and spread in this sense. The deflection means 7, however, have exactly perpendicular to the conveying direction F of each stranded sub-strand T. The middle sub-strand T is conveyed without offset by the Bahnspreizvorrichtung. It is guided by the cutting devices 4 directly to the web length compensator 25a-c, which comprises a first deflecting means 25a, a second deflecting means 25b and a third deflecting means 25c, around which the middle sub-string T is deflected in each case. All three sub-strands T are guided behind the respective third deflection device 7 or 25c via an outlet guide 8. The three sub-strands T together wrap around the outlet guide 8 and are from there via a biasing mechanism 19 in and through the printing tower 20 and finally via the hopper or the plurality of funnels 21, 22 and 23 promoted.

Figur 1 zeigt die beiden zweiten Umlenkeinrichtungen 6 und die beiden dritten Umlenkeinrichtungen 7, die eine für den linken und die andere für den rechten Teilstrang T, in ihren beiden möglichen Endpositionen, einmal außer Eingriff mit dem jeweils zugeordneten Teilstrang T und einmal in einer Endposition für maximalen Parallelversatz. Die Bewegbarkeit der Umlenkeinrichtungen 6 und 7 ist mit einem Doppelpfeil angedeutet. In der Darstellung der Figur 1 ist die obere Position der Umlenkeinrichtungen 6 und 7 die Position für Null-Spreizung, in der die Umlenkeinrichtungen 6 und 7 den jeweils zugeordneten Teilstrang T nicht berühren. Die in Figur 1 untere Position ist die Position für Maximal-Spreizung. Der Längenkompensator 25a-c ist im Zustand der maximalen Bahnwegverlängerung oder Bahnlängenvergrößerung dargestellt, den er dann einnimmt, wenn die Umlenkeinrichtung 5, 6, 7 sich im Zustand für Maximal-Spreizung befinden. Das mittlere Umlenkmittel 25b ist relativ zu den beiden anderen Umlenkmitteln 25a und 25c in Richtung auf eine Vergrößerung und in Richtung auf eine Verkleinerung der Bahnlänge des mittleren Teilstrangs T hin und her bewegbar. Die Richtung der Bewegbarkeit ist mit einem Richtungspfeil angedeutet. Die Umlenkmittel 6 und 7 und auch das Umlenkmittel 25b sind vorzugsweise längs des jeweiligen Verstellwegs stufenlos hin und her verstellbar, so dass das Ausmaß des Versatzes und abgestimmt auf den Versatz die Bahnlängenänderung des mittleren Teilstrangs T stufenlos eingestellt werden können. FIG. 1 shows the two second deflection means 6 and the two third deflection means 7, one for the left and the other for the right sub-strand T, in its two possible end positions, once disengaged from the respectively assigned sub-strand T and once in an end position for maximum parallel offset , The mobility of the deflectors 6 and 7 is indicated by a double arrow. In the presentation of the FIG. 1 is the upper position of the deflectors 6 and 7, the position for zero spread, in which the deflectors 6 and 7 do not touch the respective associated sub-string T. In the FIG. 1 lower position is the position for maximum spread. The length compensator 25a-c is shown in the state of the maximum web path extension or web length enlargement, which it occupies when the deflecting means 5, 6, 7 are in the state of maximum spread. The middle deflection means 25b is movable relative to the two other deflection means 25a and 25c in the direction of enlargement and in the direction of a reduction of the path length of the middle sub-strand T back and forth. The direction of mobility is indicated by a directional arrow. The deflecting means 6 and 7 and also the deflecting means 25b are preferably infinitely adjustable back and forth along the respective adjustment path, so that the extent of the offset and, matched to the offset, the web length change of the middle sub-strand T can be adjusted continuously.

Figur 2 zeigt die Bahnspreizvorrichtung in einer Draufsicht auf die Ebene der einlaufenden Bahn P, die auch noch die Ebene der Teilstränge T bis zu den ersten Umlenkeinrichtungen 5 ist. In der Draufsicht sind die Teilstränge mit T1 für den linken Teilstrang, T2 für den mittleren und T3 für den rechten Teilstrang bezeichnet. Die äußeren Umlenkeinrichtungen werden durch Verwendung der Buchstaben "l" für links und "r" für rechts unterschieden. Die linken und rechten Umlenkmittel 5l, 6l und 7l sowie 5r, 6r und 7r sind symmetrisch zu einer gedachten, in Förderrichtung F erstreckten Mittellinie angeordnet. Die ersten und zweiten Umlenkmittel 5l und 6l sowie 5r und 6r weisen in der Draufsicht pfeilförmig gegen die Förderrichtung F, stoßen in der Mitte jedoch nicht aneinander. Vielmehr bleibt zwischen den Umlenkmitteln 5l und 5r sowie 6l und 6r soviel Platz, dass der mittlere Teilstrang T2 zwischen den linken und rechten Umlenkmitteln 51, 61 und 71 sowie 5r, 6r und 7r auf geradem Wege, ohne Richtungsänderung zu dem in Förderrichtung F abwärts angeordneten Bahnlängenkompensator 25a-c gefördert werden kann. FIG. 2 shows the web spreading device in a plan view of the plane of the incoming web P, which is also the level of the partial strands T to the first deflection means 5. In the plan view, the sub-strands with T 1 for the left sub-strand, T 2 for the middle and T 3 are designated for the right sub-strand. The outer diverters are distinguished by the use of the letters "l" for left and "r" for right. The left and right deflection means 5l, 6l and 7l and 5r, 6r and 7r are arranged symmetrically to an imaginary, extended in the conveying direction F center line. The first and second deflection means 5l and 6l as well as 5r and 6r have an arrow shape in the plan view against the conveying direction F, but do not abut one another in the middle. Rather, between the deflection means 5l and 5r and 6l and 6r so much space remains that the middle sub-strand T 2 between the left and right deflection means 51, 61 and 71 and 5r, 6r and 7r in a straight line, can be conveyed without change of direction to the down in the conveying direction F arranged Bahnlängenkompensator 25a-c.

Die linken und rechten Umlenkmittel 5l bis 7r und der Bahnlängenkompensator 25a-c sind nicht nur wie bereits erwähnt für das Spreizen und die Bahnlängenkompensation in Bezug auf die Ebene des jeweiligen Teilstrangs T1, T2 oder T3 heb- und senkbar, in Figur 1 in vertikaler Richtung, sondern zwecks Anpassung an unterschiedlich breite Bahnen P oder zum Längsschneiden in unterschiedlich breite Teilstränge T1, T2 und T3 quer zur Förderrichtung F und zu der Richtung der Heb- und Senkbeweglichkeit bewegbar. Im Ausführungsbeispiel ist die zweite Art der Beweglichkeit eine Horizontalbeweglichkeit.The left and right deflection means 5l to 7r and the Bahnlängenkompensator 25a-c are not only raised and lowered as already mentioned for the spreading and the path length compensation with respect to the level of the respective sub-string T 1 , T 2 or T 3 , in FIG. 1 in the vertical direction, but for the purpose of adaptation to different widths of webs P or for longitudinal cutting in different width strands T 1 , T 2 and T 3 transversely to the conveying direction F and to the direction of lifting and lowering mobility movable. In the embodiment, the second type of mobility is a horizontal mobility.

Mit G ist ein ortsfestes Gestell, beispielsweise das Maschinengestell oder ein eigenes ortsfestes Gestell der Bahnspreizvorrichtung bezeichnet. Die Bahnspreizvorrichtung umfasst eine linke Lagereinrichtung 3 für die linken Umlenkmittel 5l, 6l und 7l und eine rechte Lagereinrichtung 3 für die rechten Umlenkmittel 5r, 6r und 7r. Die beiden Lagereinrichtungen 3 werden von dem Gestell G aufeinander zu und voneinander weg bewegbar gelagert. Die Lagereinrichtungen 3 sind vom Gestell lineargeführte Schlitten. Die ersten Umlenkmittel 5l und 5r sind bezüglich der jeweiligen Lagereinrichtung 3 ortsfest angeordnet. Die Umlenkmittel 5l und 5r sind fest mit der jeweiligen Lagereinrichtung 3 verbundene Umlenkstangen, die vorteilhafterweise über eine innere Druckluftzuführung an ihrem äußeren Umfang mit Luft umspült werden können, um die Reibung für den jeweiligen Teilstrang T1 oder T3 beim Spreizen zu verringern.With G is a fixed frame, for example, the machine frame or a separate stationary frame of Bahnspreizvorrichtung referred. The web spreading device comprises a left bearing device 3 for the left deflection means 5l, 6l and 7l and a right bearing means 3 for the right deflection means 5r, 6r and 7r. The two storage facilities 3 are supported by the frame G toward and away from each other movably. The storage facilities 3 are linearly guided by the frame slide. The first deflection means 5l and 5r are arranged stationary relative to the respective bearing device 3. The deflection means 5l and 5r are fixedly connected to the respective bearing means 3 deflecting rods, which can advantageously be flushed via an inner compressed air supply at its outer periphery with air in order to reduce the friction for the respective sub-strand T 1 or T 3 during spreading.

Die Bahnspreizvorrichtung umfasst ferner einen linken Träger 10l für die linken Umlenkmittel 6l und 7l und einen rechten Träger 10r für die rechten Umlenkeinrichtungen 6r und 7r. Der linke Träger 10l ist an der linken Lagereinrichtung 3 und der rechte Träger 10r ist an der rechten Lagereinrichtung 3 heb- und senkbar abgestützt. Die Lagereinrichtungen 3 bilden hierfür jeweils eine Linearführung für den zugeordneten Träger 101 oder 10r. Die Umlenkmittel 61 und 71 sind an dem Träger 10l und die Umlenkmittel 6r und 7r sind an dem Träger 10r ortsfest angeordnet. Die Umlenkeinrichtungen 61 und 71 sind jeweils fest montiert. Sie sind Umlenkstangen, vorzugsweise wie die Umlenkmittel 51 und 5r. Die Umlenkmittel 7l und 7r können alternativ am jeweiligen Träger 101 oder 10r drehbar um jeweils eine senkrecht zur Förderrichtung F weisende Umlenkachse gelagert sein. Durch Senken der Träger 10l und 10r werden die Umlenkmittel 61, 7l und 6r und 7r in den jeweiligen Teilstrang T1 oder T3 gesenkt, so dass sich der jeweilige Umschlingungswinkel vergrößert. Als Hebebewegung wird die Bewegung in Richtung einer Verkleinerung des jeweiligen Umschlingungswinkels verstanden. Durch eine Senkbewegung wird dementsprechend das Spreizmaß, d.h. der Parallelversatz, vergrößert und durch eine Hebebewegung verringert.The web spreading device further comprises a left support 10l for the left deflection means 6l and 7l and a right support 10r for the right deflection means 6r and 7r. The left bracket 10l is supported on the left bearing device 3, and the right bracket 10r is supported on the right bearing device 3 so as to be raised and lowered. For this purpose, the bearing devices 3 each form a linear guide for the associated carrier 101 or 10r. The deflection means 61 and 71 are on the carrier 10l and the deflection means 6r and 7r are fixedly arranged on the carrier 10r. The deflection 61 and 71 are each permanently mounted. They are deflection rods, preferably as the deflection means 51 and 5r. The deflecting means 7l and 7r may alternatively be rotatable about the respective carrier 101 or 10r by one respective direction perpendicular to the conveying direction F be facing deflection axis be stored. By lowering the carriers 10l and 10r, the deflection means 61, 7l and 6r and 7r are lowered into the respective sub-string T 1 or T 3 , so that the respective angle of wrap increases. The lifting movement is understood to mean the movement in the direction of a reduction of the respective wrap angle. By a lowering movement is accordingly the Spreizmaß, ie the parallel offset, increased and reduced by a lifting movement.

Bei dem Bahnlängenkompensator 25a-c sind das erste Umlenkmittel 25a und das dritte Umlenkmittel 25c bezüglich des Gestells G ortsfest und beide der Ober- oder Unterseite des mittleren Teilstrangs T2 zugewandt angeordnet. Die Umlenkmittel 25a und 25c sind drehgelagerte Rotationskörper mit zur Förderrichtung F des mittleren Teilstrangs T2 senkrechten Umlenkachsen. Das mittlere Umlenkmittel 25b ist auf der von den Umlenkmitteln 25a und 25c aus gesehen anderen Seite des Teilstrang T2 heb- und senkbar angeordnet. Das Umlenkmittel 25b ist nicht drehbar, aber vorzugsweise wie die Umlenkmittel 5 mit Druckluft umspülbar. Durch eine Senkbewegung in den Teilstrang T2 wird der Umschlingungswinkel vergrößert und durch eine Hebebewegung in die Gegenrichtung wieder verkleinert. Das Heben und Senken des Umlenkmittels 25b wird so vorgenommen, dass alle Teilstränge T1, T2 und T3 zwischen der Einlauf-Leiteinrichtung 2 und der Auslauf-Leiteinrichtung 8 (Figur 1) stets die gleiche Weglänge durchlaufen, d.h. gleiche Bahnlänge aufweisen, obgleich der mittlere Teilstrang T2 keinen Parallelversatz erfährt. Desweiteren ist der Bahnlängenkompensator 25a-c so eingerichtet, dass die Summe der Umschlingungswinkel des mittleren Teilstrangs T2 bei 25a, 25b und 25c zumindest im Wesentlichen, vorzugsweise genau gleich der Summe der Umschlingungswinkel der beiden anderen Teilstränge T1 und T2 bei 5l, 6l, 7l und 5r, 6r, 7r ist.In the web length compensator 25a-c, the first deflecting means 25a and the third deflecting means 25c are stationary with respect to the frame G and both are arranged facing the upper or lower side of the middle sub-string T 2 . The deflection means 25a and 25c are rotatably mounted rotary bodies with deflection axes perpendicular to the conveying direction F of the middle sub-string T 2 . The middle deflecting means 25b can be raised and lowered on the other side of the sub-string T 2 seen from the deflection means 25a and 25c. The deflection means 25b is not rotatable, but preferably as the deflection means 5 with compressed air umspülbar. By a lowering movement in the sub-strand T 2 of the wrap angle is increased and reduced by a lifting movement in the opposite direction again. The lifting and lowering of the deflection means 25b is carried out so that all partial strands T 1 , T 2 and T 3 between the inlet guide 2 and the outlet guide 8 (FIG. FIG. 1 ) always go through the same path length, ie have the same path length, although the middle sub-strand T 2 undergoes no parallel offset. Furthermore, the web length compensator 25a-c is set up so that the sum of the wrap angles of the middle sub-string T 2 at 25a, 25b and 25c is at least substantially, preferably exactly equal to the sum of the wrap angles of the other two sub-strings T 1 and T 2 at 5l, 6l , 7l and 5r, 6r, 7r.

Das mittlere Umlenkmittel 25b ist parallel zu seiner Umlenkachse längenverstellbar. Es ist hierfür als Teleskop mit einem mittleren sowie einem linken und einem rechten Teleskopteil gebildet. Das linke und das rechte Teleskopteil sind relativ zu dem mittleren Teleskopteil axial hin und her bewegbar, vorzugsweise unabhängig voneinander, wodurch die axiale Länge des Umlenkmittels 25b verstellbar ist. Die Längenverstellung ist abgestimmt auf die Verstellung der linken und der rechten Umlenkeinrichtung 5, 6 und Schneideinrichtung 4. Für die Abstimmung ist das linke Teleskopteil mit der linken Lagereinrichtung 3 und das rechte Teleskopteil mit der rechten Lagereinrichtung 3 mechanisch gekoppelt. Das mittlere Teleskopteil ist hingegen relativ zum Gestell G axial nicht beweglich, sondern nur gemeinsam mit dem linken und dem rechten Teleskopteil heb- und senkbar angeordnet. Im Hinblick auf die Heb- und Senkbeweglichkeit ist das Umlenkmittel 25b mechanisch nicht mit den Umlenkmitteln 6l, 71 und 6r, 7r gekoppelt. Die Abstimmung wird zum Zwecke der Bahnlängenkompensation steuerungstechnisch vorgenommen, d.h. elektrisch oder elektronisch.The middle deflection 25b is adjustable in length parallel to its deflection axis. It is for this purpose formed as a telescope with a middle and a left and a right telescopic part. The left and the right telescopic part are axially movable relative to the central telescopic part, preferably independently of one another, whereby the axial length of the deflection means 25b is adjustable. The length adjustment is tuned to the adjustment of the left and right deflection device 5, 6 and cutting device 4. For the vote, the left telescopic part with the left bearing device 3 and the right telescopic part with the right bearing device 3 is mechanically coupled. The middle telescope part is, however, axially movable relative to the frame G, but only together with the left and right telescopic part raised and lowered arranged. With regard to the lifting and lowering mobility, the deflecting means 25b is not mechanically coupled to the deflecting means 6l, 71 and 6r, 7r. The tuning is carried out for the purpose of Bahnlängenkompensation control technology, ie electrically or electronically.

Die linke Schneideinrichtung 4 ist an der linken Lagereinrichtung 3 und die rechte Schneideinrichtung 4 ist an der rechten Lagereinrichtung 3 abgestützt, so dass die Schneideinrichtungen 4 die Querbewegungen der jeweils zugeordneten Lagereinrichtung 3 und dementsprechend der jeweils zugeordneten Umlenkmittel 6l, 7l und 6r, 7r mitmachen, also wie die beiden querbewegbaren Teleskopteile des Umlenkmittels 25b synchron mit den linken und rechten Umlenkmitteln 61 bis 7r in Querrichtung bewegt werden.The left-hand cutting device 4 is supported on the left-hand storage device 3 and the right-hand cutting device 4 is supported on the right-hand storage device 3, so that the cutting devices 4 join in the transverse movements of the respectively associated storage device 3 and, accordingly, of the respective associated deflection means 6l, 7l and 6r, 7r, that is, how the two transversely movable telescopic parts of the deflection means 25b are moved in the transverse direction synchronously with the left and right deflection means 61 to 7r.

Die Querbewegung der Lagereinrichtungen 3 und die Längenverstellung des Umlenkmittels 25b werden mit einem linken Versteller 12 und einem rechten Versteller 12, die jeweils als elektrischer Drehmotor ausgeführt sind, bewirkt. Die Versteller 12 treiben je eine in Querrichtung erstreckte Spindel an. Die Spindeln sind je mit zwei verdrehgesichert lineargeführten Gegengliedem in einem Gewindeeingriff. Eines der Gegenglieder ist jeweils mit der zugeordneten Lagereinrichtung 3 unbeweglich verbunden, so dass diese bei einem Drehantrieb der jeweils zugeordneten Spindel in Querrichtung verfahren werden. In Figur 2 ist angedeutet, dass das linke und das rechte Teleskopteil des Umlenkmittels 25b über ein eigenes verdrehgesichert linear geführtes Gegenglied mit der jeweils zugeordneten Gewindespindel in einem Gewindeeingriff ist und die Gegenglieder der gleichen Seite fest miteinander verbunden sind. Alternativ könnten das linke Teleskopteil mit der linken Lagereinrichtung 3 und das rechte Teleskopteil mit der rechten Lagereinrichtung 3 axial steif verbunden sein, so dass die Teleskopteile die Bewegungen der jeweils zugeordneten Lagereinrichtung 3 direkt mitmachen.The transverse movement of the bearing devices 3 and the length adjustment of the deflection means 25b are effected with a left stage 12 and a right stage 12, which are each designed as an electric rotary motor. The adjusters 12 each drive a transversely extending spindle. The spindles are each in a threaded engagement with two non-rotating linearly guided counterparts. One of the counter-members is immovably connected in each case with the associated bearing device 3, so that they are moved in the case of a rotary drive of the respective associated spindle in the transverse direction. In FIG. 2 is indicated that the left and right telescopic part of the deflecting means 25b via its own twist-guided linearly guided counter-member with the respective associated threaded spindle in a threaded engagement and the counter-links of the same side are firmly connected. Alternatively, the left telescopic part with the left bearing device 3 and the right telescopic part with the right bearing device 3 could be connected axially rigid, so that the telescope parts directly participate in the movements of each associated storage device 3.

In Figur 2 ist mit PB die maximale Breite einer in der Druckmaschine verarbeitbaren Bahn P bezeichnet. Wird für die Erzeugung eines Druckprodukts eine Bahn P mit einer gegenüber der maximalen Breite PB reduzierten Breite PBred verwendet, die um das Maß von beispielsweise 6x schmaler als die Bahn maximaler Breite PB ist, wird die Bahn P reduzierter Breite PBred vorzugsweise wie dargestellt mittig vom Rollenwechsler 1 abgewickelt und mittels den beiden Schneideinrichtungen 4 längs in die drei gleichbreiten Teilstränge T1, T2 und T3 geschnitten. Die Trichter 21, 22 und 23 sind in Querrichtung zur Förderrichtung F so angeordnet, dass im Falle der Verarbeitung einer Bahn P der maximalen Breite PB diese Bahn in drei gleichbreite Teilstränge geschnitten und diese Teilstränge ohne Versatz mittig auf den jeweils zugeordneten Trichter 21, 22 oder 23 gefördert und längsgefalzt werden. Um die drei Teilstränge T1, T2, T3 ebenfalls mittig auf den jeweils zugeordneten Trichter 21, 22, 23 zu fördern, werden der linke Teilstrang T1 und der rechte Teilstrang T3 nach außen jeweils um das Spreizmaß 2x versetzt. Nach dem Spreizen verlaufen die äußeren Seitenränder der Teilstränge T1 und T3 um das Maß x innerhalb der gedachten äußeren Seitenränder einer Bahn der maximalen Breite PB. Der mittlere Teilstrang T2 wird ohne Versatz durch die Bahnspreizvorrichtung geführt. Er umschlingt dabei nacheinander die Umlenkmittel 25a, 25b und 25c des Bahnlängenkompensators 25a-c, wobei das Umlenkmittel 25b soweit in den Teilstrang T2 gesenkt ist, dass der mittlere Teilstrang T2 zwischen der Einlauf-Leiteinrichtung 2 und der Auslauf-Leiteinrichtung 8 die gleiche Länge wie die beiden äußeren Teilstränge T1 und T3 aufweist.In FIG. 2 PB denotes the maximum width of a web P that can be processed in the printing machine. If, for the production of a printed product, a web P with a width PB red reduced by the amount of, for example, 6x narrower than the web of maximum width PB is used, the web P of reduced width PB red preferably becomes centered as shown unwound from the roll changer 1 and by means of the two Cutting devices 4 longitudinally cut into the three equal width sub-strands T 1 , T 2 and T 3 . The funnels 21, 22 and 23 are arranged in the transverse direction to the conveying direction F so that in the case of processing a web P of the maximum width PB this web cut into three equal-width sub-strands and these sub-strands without offset centrally on the respectively associated hopper 21, 22 or 23 are promoted and longitudinally folded. In order to promote the three sub-strands T 1 , T 2 , T 3 also centered on the respectively associated hopper 21, 22, 23, the left sub-strand T 1 and the right sub-strand T 3 are offset to the outside by the Spreizmaß 2x. After spreading, the outer side edges of the partial strands T 1 and T 3 extend by the dimension x within the imaginary outer side edges of a web of the maximum width PB. The middle sub-strand T 2 is guided without offset through the web spreading device. He wraps successively the deflection means 25a, 25b and 25c of Bahnlängenkompensators 25a-c, wherein the deflection means 25b is lowered so far in the sub-strand T 2 that the middle sub-strand T 2 between the inlet guide 2 and the outlet guide 8, the same Length as the two outer sub-strands T 1 and T 3 has.

Figur 3 zeigt den Bahnlängenkompensator 25a-c. Die äußeren Teilstränge T1 und T3 werden vom Bahnlängenkompensator 25a-c nicht beeinflusst. Dargestellt ist ein Beispielfall, in dem die verarbeitete Bahn P eine Breite von 3X aufweist und in die drei Teilstränge T1, T2 und T3 mit je der Breite X längsgeschnitten wird. Die beiden äußeren Teilstränge T1 und T3 werden um ein bestimmtes Spreizmaß, beispielsweise jeweils 2x, nach außen versetzt. Das längenverstellbare Umlenkmittel 25b weist eine variable axiale Länge Y auf, die entsprechend der Breite X des mittleren Teilstrangs T2 stufenlos verstellbar ist. Die Länge Y kann exakt der Strangbreite X entsprechen oder aber ein gewisses Übermaß aufweisen, dass jedoch zu jeder axialen Seite hin kleiner als das Spreizmaß ist, damit das Umlenkmittel 25b in den mittleren Teilstrang T2 gesenkt werden kann ohne die beiden äußeren Teilstränge T1 und T3 zu berühren. FIG. 3 shows the web length compensator 25a-c. The outer sub-strands T 1 and T 3 are not affected by the Bahnlängenkompensator 25a-c. Shown is an example case in which the processed web P has a width of 3X and is longitudinally cut into the three sub-strands T 1 , T 2 and T 3 , each with the width X. The two outer sub-strands T 1 and T 3 are offset by a certain Spreizmaß, for example, each 2x, to the outside. The length-adjustable deflection means 25b has a variable axial length Y, which is infinitely variable according to the width X of the central sub-string T 2 . The length Y may correspond exactly to the strand width X or have a certain oversize, but that is smaller than the Spreizmaß to each axial side, so that the deflection 25b can be lowered into the middle sub-strand T 2 without the two outer sub-strands T 1 and T 3 to touch.

Figur 4 zeigt die Spreizoperation in einer schematischen Darstellung in einer Draufsicht auf die Bahn P und die Teilstränge T1, T2 und T3 senkrecht zur Förderrichtung F am Ein- und Auslauf der Bahnspreizvorrichtung. Eingezeichnet sind die beiden Endpositionen, zwischen denen die linke und die rechte Lagereinrichtung 3 und dementsprechend die beiden Schneideinrichtungen 4 und die Umlenkmittel 61, 71 und 6r, 7r in Querrichtung hin und her verstellt werden können. Der maximale Verstellweg ist mit x bezeichnet. Entsprechend können Bahnbreiten zwischen PB und PBred = PB-6x mittels der Bahnspreizvorrichtung verarbeitet werden. Dargestellt ist der auch in Figur 2 angenommene Beispielfall der Verarbeitung einer Bahn P der minimalen Bahnbreite PB-6x. Die Lagereinrichtungen 3 nehmen dementsprechend jeweils ihre innere Endposition ein, in der sie voneinander den geringsten in Querrichtung gemessenen Abstand haben. Aus dieser inneren Endposition können sie für die Verarbeitung breiterer Bahnen P bis hin zur maximalen Bahnbreite PB jeweils nach außen verstellt werden, vorzugsweise stufenlos. FIG. 4 shows the spreading operation in a schematic representation in a plan view of the web P and the sub-strands T 1 , T 2 and T 3 perpendicular to the conveying direction F at the inlet and outlet of the web spreading device. Shown are the two end positions, between which the left and right bearing means 3 and, accordingly, the two cutting devices 4 and the deflection means 61, 71 and 6r, 7r can be moved back and forth in the transverse direction. The maximum adjustment path is designated by x. Accordingly, web widths between PB and PB red = PB-6x are processed by means of the web spreading device. Shown is also in FIG. 2 assumed example case of the processing of a web P of the minimum web width PB-6x. The storage facilities 3 accordingly each take their inner end position, in which they have the smallest measured distance in the transverse direction from each other. From this inner end position, they can be adjusted for the processing of wider webs P up to the maximum web width PB to the outside, preferably continuously.

Figur 5 zeigt in einer schematischen Darstellung einer Bahn P und daraus gebildeter Teilstränge T12, T1, T2 und T3 ein Spreizbeispiel für eine Bahnspreizvorrichtung eins zweiten Ausführungsbeispiels. Die Bahn P wird in einer ersten Schnittoperation mittels einer nicht beweglich montierten Schneideinrichtung 4 nur in zwei Teilstränge längs geschnitten, nämlich die Teilstränge T12 und T3. Der Teilstrang T12 ist doppelt so breit wie der Teilstrang T3. Der Teilstrang T12 wird mit nicht dargestellten, in der Draufsicht der Figur 5 linken Umlenkmitteln nach links und der Teilstrang T3 wird mit nicht dargestellten, in der Draufsicht rechten Umlenkmitteln nach rechts versetzt. Die rechten Umlenkmittel der modifizierten Bahnspreizvorrichtung können den rechten Umlenkmitteln 5r, 6r und 7r des ersten Ausführungsbeispiels entsprechen. Die linken Umlenkmittel werden durch gerade Verlängerung der linken Umlenkmittel 51, 61 und 71 der Bahnspreizvorrichtung des ersten Ausführungsbeispiels erhalten. Die modifizierten Umlenkmittel unterscheiden sich von den Umlenkmitteln des ersten Ausführungsbeispiels lediglich durch ihre axiale Länge, die der doppelten Länge der Umlenkmittel 51, 61 und 71 entspricht. Der Teilstrang T12 wird um solch ein Spreizmaß versetzt, dass er auf die beiden Trichter 21 und 22 zentriert weiterläuft. Die parallel zur Förderrichtung F gedachte Mittellinie des Teilstrangs T12 verläuft mittig zwischen den Trichtern 21 und 22. Der Teilstrang T12 wird mittels einer in Förderrichtung F abwärtigen weiteren fest montierten Schneideinrichtung 4 in die beiden Teilstränge T1 und T2 längs geschnitten. Die Teilstränge T1 und T2 werden je mit einer Umlenkeinrichtung voneinander abgespreizt, d.h. je parallel voneinander weg versetzt, so dass der Teilstrang T1 mittig auf den Trichter 21 und der Teilstrang T2 mittig auf den Trichter 22 weitergefördert wird. Die Umlenkeinrichtungen für die Teilstränge T1 und T2 können wie von herkömmlichen Bahnspreizvorrichtungen bekannt gestaltet sein. Ein bevorzugtes Beispiel für eine derartige Spreizvorrichtung wird in der DE 103 37 248 A1 beschrieben. Die bahnabwärtige Schneideinrichtung 4 und die beiden bahnabwärtigen Umlenkeinrichtungen für die Teilstränge T1 und T2 können in der Maschine separat von der bahnaufwärtigen Schneideinrichtung 4 und den beiden bahnaufwärtigen Umlenkeinrichtungen für die Teilstränge T12 und T3 angeordnet oder zu einer kompakten Bahnspreizvorrichtung in einem gemeinsamen Gestell vereinigt sein. Die bahnabwärtige Schneideinrichtung 4 und die zugeordneten Umlenkeinrichtungen für die Teilstränge T1 und T2 können sogar nach dem Druckwerk oder den mehreren Druckwerken für die Teilstränge T1 und T2 angeordnet sein. FIG. 5 shows in a schematic representation of a web P and formed therefrom sub-strands T 12 , T 1 , T 2 and T 3, a spreading example for a web spreading device a second embodiment. The web P is cut longitudinally in a first cutting operation by means of a non-movably mounted cutting device 4 only in two partial strands, namely the partial strands T 12 and T 3 . The sub-strand T 12 is twice as wide as the sub-strand T 3 . The sub-strand T 12 is not shown in the top view of FIG. 5 left deflection to the left and the sub-strand T 3 is not shown, right in the plan view deflection to the right. The right deflection means of the modified web spreading device may correspond to the right deflection means 5r, 6r and 7r of the first embodiment. The left deflection means are obtained by straight extension of the left deflection means 51, 61 and 71 of the web spreading device of the first embodiment. The modified deflection means differ from the deflection means of the first embodiment only by their axial length, which corresponds to twice the length of the deflection means 51, 61 and 71. The sub-strand T 12 is offset by such a Spreizmaß that it continues to run centered on the two funnels 21 and 22. The imaginary parallel to the conveying direction F center line of the sub-strand T 12 runs centrally between the hoppers 21 and 22. The sub-strand T 12 is longitudinally cut by means of a downstream in the conveying direction F further fixed cutter 4 in the two sub-strands T 1 and T 2 . The sub-strands T 1 and T 2 are each spread apart with a deflection device, ie each offset away from each other away from each other, so that the sub-strand T 1 centered on the hopper 21 and the sub-strand T 2 centered on the hopper 22 on. The diverters for the partial strands T 1 and T 2 may be designed as known from conventional Bahnspreizvorrichtungen. A preferred example of such a spreading device is in the DE 103 37 248 A1 described. The downstream cutter 4 and the two downstream Diverters for the partial strands T 1 and T 2 may be arranged in the machine separately from the upstream cutter 4 and the two upstream diverters for the partial strands T 12 and T 3 , or combined into a compact web spreader in a common rack. The downstream cutting device 4 and the associated deflection devices for the partial strands T 1 and T 2 can even be arranged downstream of the printing unit or the multiple printing units for the partial strands T 1 and T 2 .

Figur 6 zeigt Beispiele für unterschiedliche Spreizoperationen, die mit der Bahnspreizvorrichtung des ersten Ausführungsbeispiels ausführbar sind. Das Beispiel I entspricht der anhand der Figuren 1 bis 4 erläuterten Spreizoperation. FIG. 6 shows examples of different spreading operations, which are executable with the web spreading device of the first embodiment. Example I corresponds to the basis of FIGS. 1 to 4 explained spreading operation.

Bei Ausführung der im Beispiel II dargestellten Spreizoperation wird die Bahn P nur mittels der linken Schneideinrichtung 4 geschnitten, so dass der linke Teilstrang T1 und ein breiter rechter Teilstrang entstehen, der in Figur 6 mit T2 + T3 bezeichnet ist. Der Teilstrang T1 wird mittels der Umlenkeinrichtung 51, 61, 71 abgespreizt, und der rechte Teilstrang T2 + T3 wird ohne Eingriff mit der rechten Umlenkeinrichtung 5r, 6r, 7r und dementsprechend ohne Versatz durch die Bahnspreizvorrichtung gefördert. Vorzugsweise wird der Teilstrang T2 + T3 jedoch mittels des Bahnlängenkompensators 25a-c innerhalb der Bahnspreizvorrichtung auf die gleiche Länge wie der Teilstrang T1 gebracht. Das Umlenkmittel 25b ist in bevorzugten Ausführungen daher bis zum rechten Seitenrand des nicht gespreizten Teilstrangs T2 + T3 verlängerbar, d.h. das rechte Teleskopteil weist eine ausfahrbare Länge auf, die zumindest im Wesentlichen der Länge des Mittelteils des Umlenkmittels 25b entspricht. Spiegelbildlich die gleiche Spreizoperation zeigt das Beispiel III, wobei mittels nur der rechten Schneideinrichtung 4 ein rechter Teilstrang T3 und ein doppelt breiter linker Teilstrang T1 + T2 erzeugt wird. Die Erläuterungen zum Beispiel II gelten sinngemäß auch für das Beispiel III zur anderen Seite der Bahnspreizvorrichtung hin. Die Beispiele II und III demonstrieren die Flexibilität der Bahnspreizvorrichtung. Für die Ausführung dieser Spreizoperationen wird im Beispiel II nur die linke Umlenkeinrichtung 5l, 6l, 7l und im Ausführungsbeispiel III nur die rechte Umlenkeinrichtung 5r, 6r, 7r zum Einsatz gebracht, während die jeweils andere mit dem Teilstrang T2 + T3 im Beispiel II und dem Teilstrang T1 + T2 im Beispiel III keine Berührung hat, zumindest keine Berührung hat, die eine Umlenkung bewirkt.When carrying out the spreading operation shown in Example II, the web P is cut only by means of the left cutting device 4, so that the left sub-strand T 1 and a wider right sub-strand arise, the in FIG. 6 with T 2 + T 3 is designated. The sub-strand T 1 is spread by means of the deflection 51, 61, 71, and the right sub-strand T 2 + T 3 is promoted without intervention with the right deflection 5r, 6r, 7r and accordingly without offset by the Bahnspreizvorrichtung. Preferably, however, the sub-strand T 2 + T 3 is brought to the same length as the sub-strand T 1 by means of the web length compensator 25a-c within the web spreading device. The deflecting means 25b is in preferred embodiments therefore extendable to the right side edge of the non-spread partial strand T 2 + T 3 , ie the right telescopic part has an extendable length which corresponds at least substantially to the length of the central part of the deflection means 25b. The same spreading operation is shown in mirror image form in Example III, wherein a right partial strand T 3 and a double width left partial strand T 1 + T 2 are produced by means of only the right cutting device 4. The explanations for Example II apply mutatis mutandis to the example III to the other side of the Bahnspreizvorrichtung out. Examples II and III demonstrate the flexibility of the web spreading device. For the execution of these spreading operations, only the left deflection device 5l, 6l, 7l and in the embodiment III only the right deflection device 5r, 6r, 7r are used in Example II, while the other with the partial strand T 2 + T 3 in Example II and the sub-string T 1 + T 2 in Example III has no contact, at least has no contact, which causes a deflection.

Die Beispiele IV und V zeigen Spreizoperationen für Bahnen P mit 4/6-Breite, die asymmetrisch zur axialen Mitte des Rollenwechslers 1 abgewickelt werden. Die Abwicklung ist so, dass nach dem Schnitt der im Beispiel IV rechte Teilstrang T2 und der im Beispiel 5 linke Teilstrang T2 ohne Versatz mittig durch die Bahnspreizvorrichtung gefördert und entweder der linke Teilstrang T1 im Beispiel IV oder der rechte Teilstrang T3 im Beispiel V nach links oder nach rechts außen versetzt wird. Entsprechend kommt im Beispiel IV die rechte Umlenkeinrichtung 5r, 6r, 7r und im Beispiel V die linke Umlenkeinrichtung 5l, 6l, 7l nicht zum Einsatz.Examples IV and V show spreading operations for 4/6-width sheets P which are unwound asymmetrically to the axial center of the roll exchanger 1. The development is such that after the cut of the right in Example IV partial strand T 2 and left in Example 5 left partial strand T 2 without offset centered by the Bahnspreizvorrichtung and either the left sub-strand T 1 in Example IV or the right sub-strand T 3 im Example V is offset to the left or to the right outside. Accordingly, in the example IV, the right-hand deflection device 5r, 6r, 7r and in the example V the left-hand deflection device 5l, 6l, 7l are not used.

Im Beispiel VI wird eine Bahn P entsprechend dem Beispiel IV verarbeitet, während im Beispiel VII eine Bahn entsprechend dem Beispiel V verarbeitet wird. Allerdings werden im Unterschied zu den Beispielen IV und V jeweils beide Teilstränge versetzt. Im Beispiel VI wird der rechte Teilstrang T3 wie zum ersten Ausführungsbeispiel beschrieben nach rechts außen gespreizt. Um den in Bezug auf die Druckmaschine mittig in die Bahnspreizvorrichtung einlaufenden linken Teilstrang T1 mittig auf den Trichter 22 zu spreizen, wird die linke Lagereinrichtung 3 mit insbesondere der linken Umlenkeinrichtung 5l, 6l, 7l entsprechend weit nach rechts verstellt. Die Bahn P wird mit einer der Schneideinrichtungen 4 längs geschnitten, während die andere Schneideinrichtung 4 außer Eingriff ist, und mittels der linken Umlenkeinrichtung 5l, 61, 7l wie dargestellt gespreizt. Das Beispiel VII entspricht spiegelbildlich dem Beispiel VI, wobei die rechte Lagereinrichtung 3 mit insbesondere der rechten Umlenkeinrichtung 5r, 6r, 7r entsprechend weit nach links verstellt wurde. Eine derart extreme Verstellbarkeit der linken oder der rechten Lagereinrichtung 3 ist ein optionales Merkmal der Bahnspreizvorrichtung.In Example VI, a web P is processed according to Example IV, while in Example VII, a web is processed according to Example V. However, unlike Examples IV and V, both partial strands are offset. In Example VI, the right sub-string T 3 as described for the first embodiment is spread to the right outside. In order to spread the center part of the web spreading device in relation to the web spreading device T 1 centered on the hopper 22, the left-hand bearing device 3, in particular the left-hand deflection device 5l, 6l, 7l, is adjusted correspondingly far to the right. The web P is longitudinally cut with one of the cutters 4, while the other cutter 4 is disengaged, and spread by means of the left hand deflector 5l, 61, 7l as shown. Example VII corresponds in mirror image to example VI, with the right-hand bearing device 3, in particular the right-hand deflection device 5r, 6r, 7r, being adjusted correspondingly far to the left. Such extreme adjustability of the left or right bearing device 3 is an optional feature of the web spreading device.

Die Figuren 7 bis 9 zeigen einen Längendehnungskompensator 26 mit einer im Bahnweg vorgeordneten Führungseinrichtung 27. Der Längendehnungskompensator 26 und die bevorzugt damit in Kombination eingesetzte Führungseinrichtung 27 kann insbesondere zwischen zwei auf die Teilstränge T1 bis T3 druckenden Druckwerken im Druckturm 20 angeordnet sein. Bevorzugte Merkmale solch einer Einrichtung werden in der DE 10 2005 048 246.5 beschrieben.The FIGS. 7 to 9 The length expansion compensator 26 and the guiding device 27 preferably used in combination therewith can be arranged in particular between two printing units in the printing tower 20 that print on the partial strands T 1 to T 3 . Preferred features of such a device are in DE 10 2005 048 246.5 described.

Die Figuren 10 und 11 zeigen eine Bahnspreizvorrichtung eines dritten Ausführungsbeispiels. Die Bahnspreizvorrichtung umfasst wie bereits anhand des ersten Ausführungsbeispiels erläutert eine linke und eine rechte Lagereinrichtung 3, von denen in den Figuren nur die linke Lagereinrichtung 3 mit den von ihr gelagerten Komponenten dargestellt ist. Die linke Schneideinrichtung 4 und die linken Umlenkmittel 5l, 6l und 7l sind wie im ersten Ausführungsbeispiel fliegend gelagert, so dass sie nach innen in Richtung auf die rechte Seite der Bahnspreizvorrichtung frei abragen, also freie Enden aufweisen. Mit 10l ist ein linker Träger bezeichnet, der wie im ersten Ausführungsbeispiel von der linken Lagereinrichtung 3 heb- und senkbar gelagert wird. Bezüglich der Spreizoperationen für den linken Teilstrang T1 und den nicht dargestellten rechten Teilstrang T2 und der Konstruktion und Anordnung der hierfür vorgesehenen Komponenten, nämlich die Lagereinrichtungen 3, der Träger 101 und ein nicht dargestellter Träger 10r und insbesondere die Umlenkeinrichtungen 51, 61 und 71 und 5r, 6r und 7r, wird auf die Ausführungen zum ersten Ausführungsbeispiel verwiesen.The Figures 10 and 11 show a web spreading device of a third embodiment. As already explained with reference to the first exemplary embodiment, the web spreading device comprises a left and a right bearing device 3, of which only the left bearing device 3 with the components stored by it is shown in the figures. The left cutting device 4 and the left deflection means 5l, 6l and 7l are cantilevered as in the first embodiment, so that they protrude freely inwardly in the direction of the right side of the web spreading device, so have free ends. With 10l a left carrier is referred to, which is mounted and lowered as in the first embodiment of the left bearing means 3. With respect to the spreading operations for the left sub-string T 1 and the right sub-string T 2, not shown, and the construction and arrangement of the components provided therefor, namely the storage facilities 3, the carrier 101 and a carrier 10r, not shown, and in particular the deflection 51, 61 and 71st and 5r, 6r, and 7r, reference is made to the explanations of the first embodiment.

Im Unterschied zum ersten Ausführungsbeispiel ist ein Bahnlängenkompensator 5m, 6m, 7m für den mittleren Teilstrang T2 nicht in Förderrichtung F abwärts von den beiden äußeren Umlenkeinrichtungen angeordnet, sondern im Wesentlichen auf der gleichen Höhe zwischen der linken Umlenkeinrichtung 51, 61, 7l und der rechten Umlenkeinrichtung 5r, 6r, 7r. Der Bahnlängenkompensator 5m, 6m, 7m ist bezüglich der Förderrichtung F nicht exakt auf der gleichen Höhe wie die beiden äußeren Umlenkeinrichtungen angeordnet. Die Umlenkmittel 5m, 6m und 7m sind in Bezug auf die Förderrichtung F ein wenig versetzt zu den entsprechenden äußeren Umlenkmitteln 51 bis 7r angeordnet. Der Versatz ist so gewählt, dass die quer zur Förderrichtung F gemessene axiale Länge der mittleren Umlenkmittel 5m, 6m und 7m entsprechend der Breite des mittleren Teilstrangs T2 verstellt werden kann. Hierfür kann jedes der Umlenkmittel 5m, 6m und 7m entsprechend dem Umlenkmittel 25b des ersten Ausführungsbeispiels als Teleskopteil gebildet sein. Das mittlere erste Umlenkmittel 5m ist in nicht dargestellter Weise ortsfest bezüglich des Gestells G gelagert. Das mittlere zweite Umlenkmittel 6m und das mittlere dritte Umlenkmittel 7m sind gemeinsam an einem mittleren Träger 10m befestigt, der relativ zu dem Gestell G heb- und senkbar ist. Die Umlenkmittel 5m, 6m und 7m sind nicht drehbar montiert. Vorzugsweise sind sie zur Verminderung der Reibung luftumspült.In contrast to the first embodiment, a Bahnlängenkompensator 5m, 6m, 7m for the middle sub-strand T 2 is not arranged in the conveying direction F down from the two outer deflection, but substantially at the same height between the left deflecting 51, 61, 7l and the right Turning device 5r, 6r, 7r. The web length compensator 5m, 6m, 7m is not arranged with respect to the conveying direction F exactly at the same height as the two outer deflection devices. The deflection means 5m, 6m and 7m are arranged with respect to the conveying direction F a little offset from the corresponding outer deflection means 51 to 7r. The offset is selected such that the axial length of the middle deflecting means 5m, 6m and 7m measured transversely to the conveying direction F can be adjusted in accordance with the width of the middle sub-string T 2 . For this purpose, each of the deflection means 5m, 6m and 7m may be formed according to the deflection means 25b of the first embodiment as a telescopic part. The middle first deflection means 5m is mounted in a manner not shown stationary with respect to the frame G. The middle second deflection means 6m and the middle third deflection means 7m are fastened together to a central support 10m, which can be raised and lowered relative to the frame G. The deflection 5m, 6m and 7m are not rotatably mounted. Preferably, they are air-rinsed to reduce friction.

Die Heb- und Senkbewegung der Umlenkmittel 6m und 7m wird mittels eines Hub- und Senkmechanismus bewirkt, der im Ausführungsbeispiel als Gestänge gebildet ist. Der Mechanismus umfasst zwei Achsen 14, die sich parallel zu den Umlenkmitteln 6m und 7m quer zur Förderrichtung F erstrecken. Der Mechanismus umfasst ferner Gestängearme 15, die in der Art eines Scherenmechanismus wirken. Die Gestängearme 15 sind je an einem Ende schwenkbar mit einer der Achsen 14 und an ihrem anderen Ende gelenkig je in einem Drehgelenk 16 entweder mit dem Gestell G oder dem Träger 10m verbunden. Die Befestigung am Gestell G kann beispielsweise durch nicht dargestellte Öffnungen der linken und der rechten Lagereinrichtung 3 vorgenommen werden. Die Gestängearme 15 sind gelenkig einerseits mit jeweils einer der Achsen 14 und andererseits entweder dem Träger 10m oder dem Gestell G so verbunden, dass sie einander jeweils paarweise auf einer der Achsen 14 kreuzen und von der betreffenden Achse 14 ausgehend zwei Schenkel eines "V" bilden, die um die jeweilige Achse 14 aufeinander zu und voneinander weg klappbar sind.The lifting and lowering movement of the deflection 6m and 7m is effected by means of a lifting and lowering mechanism, which is formed in the embodiment as a rod. The mechanism comprises two axes 14, which extend transversely to the conveying direction F parallel to the deflection means 6m and 7m. The mechanism further includes linkage arms 15 which operate in the manner of a scissor mechanism. The link arms 15 are each pivotally connected at one end to one of the axles 14 and at the other end each pivotally connected in a swivel joint 16 to either the frame G or the carrier 10m. The attachment to the frame G can be made for example by not shown openings of the left and the right bearing device 3. The link arms 15 are articulated on the one hand with one of the axles 14 and on the other hand either the carrier 10m or the frame G connected so that they each intersect in pairs on one of the axes 14 and form of the respective axis 14, starting two legs of a "V" which are foldable about the respective axis 14 toward and away from each other.

Der Hub- und Senkmechanismus umfasst ferner einen Versteller 12, im dritten Ausführungsbeispiel ebenfalls ein elektrischer Drehmotor, und ein Koppelglied 13, das auch im dritten Ausführungsbeispiel als Spindel gebildet ist. Der Versteller 12 ist an einer der Achsen 14 befestigt. Das Koppelglied 13 erstreckt sich quer zu den beiden Achsen 14 und koppelt die beiden Achsen 14 miteinander, indem es mit jeder der Achsen 14 in einem Koppeleingriff ist. Der Koppeleingriff ist als Gewindeeingriff gestaltet. Das Koppelglied 13 wird von dem Versteller 12 drehangetrieben, so dass die nicht verdrehbaren Achsen 14 im Gewindeeingriff in Abhängigkeit von der Drehrichtung des Koppelglieds 13 voneinander weg oder aufeinander zu bewegt werden. Durch eine Bewegung der Achsen 14 aufeinander zu werden die paarweise ein V bildenden Gestängearme 15 voneinander weggeschwenkt und der Träger 10m mit den daran befestigten Umlenkmitteln 6m und 7m in den Teilstrang T2 gesenkt. Derartige Hub- und Senkmechanismen finden beispielsweise für Wagenheber Verwendung, wobei dort im Allgemeinen der motorische Versteller 12 durch eine Handkurbel ersetzt ist.The lifting and lowering mechanism further comprises an adjuster 12, in the third embodiment also an electric rotary motor, and a coupling member 13, which is also formed in the third embodiment as a spindle. The stage 12 is attached to one of the axles 14. The coupling member 13 extends transversely to the two axles 14 and couples the two axles 14 to each other by being in mating engagement with each of the axles 14. The coupling engagement is designed as a threaded engagement. The coupling member 13 is rotationally driven by the adjuster 12, so that the non-rotatable axes 14 in the threaded engagement depending on the direction of rotation of the coupling member 13 are moved away from each other or towards each other. The pairs a V-forming linkage arms 15 to be by a movement of the axes for 14 pivoted away from each other and the carrier 10m lowered into the subphase T 2 with the attached deflecting means and 6m 7m. Such lifting and lowering mechanisms are used, for example, for jack, where there is generally replaced the motorized stage 12 by a hand crank.

Die Auslauf-Leiteinrichtung des zweiten Ausführungsbeispiels umfasst zwei drehgelagerte, dicht nebeneinander angeordnete Walzen 8 und 9, die sich jeweils über die gesamte Breite der Bahnspreizvorrichtung erstrecken und vom Gestell G drehgelagert werden. Durch solch eine Anordnung wird der Umschlingungswinkel pro Walze im Vergleich mit einer einzigen Walze und gleichem Umlenkungsgrad verringert. Die gespreizten Teilstränge T1 und T3 und der in Bezug auf seine Bahnlänge angeglichene Bahnstrang T2 umschlingen nebeneinander die Auslauf-Leiteinrichtung 8, 9 und werden anschließend über das Vorspannwerk 19 in den Druckturm 20 gefördert, wie dies anhand des ersten Ausführungsbeispiels beschrieben wird. Die Bahnspreizvorrichtung des dritten Ausführungsbeispiels ist sehr kompakt, was in erster Linie auf die Anordnung des Kompoensators 5m, 6m, 7m zwischen den beiden äußeren Umlenkeinrichtungen 51 bis 7r zurückzuführen ist. Zur Kompaktheit trägt ferner bei, dass die zweiten und dritten Umlenkmittel 61, 71, 6m, 7m, 6r und 7r von der gleichen Seite her in den jeweiligen Teilstrang senkbar angeordnet sind und auch, dass die Teilstränge T1 bis T3 mittels der Auslauf-Leiteinrichtung 8, 9 wieder zurück in Richtung auf die Schneideinrichtung 4 geführt werden, im Ausführungsbeispiel parallel zur einlaufenden Bahn P. Sie werden vor, bei oder auch erst hinter der Schneideinrichtung 4 umgelenkt, in der Darstellung der Figur 10 nach oben und dann weiter zum Vorspannwerk 19 gefördert.The outlet guide of the second embodiment comprises two rotatably mounted, closely spaced rollers 8 and 9, each extending over the entire width of the web spreading device and rotatably supported by the frame G. By such an arrangement, the wrap angle per roll becomes as compared with a single roll and reduced the same degree of indirection. The spread partial strands T 1 and T 3 and the aligned with respect to its web length web strand T 2 wrap around the outlet guide 8, 9 and are then fed via the biasing unit 19 in the printing tower 20, as will be described with reference to the first embodiment. The web spreading device of the third embodiment is very compact, which is primarily due to the arrangement of the Komposensators 5m, 6m, 7m between the two outer deflectors 51 to 7r. For compactness further contributes that the second and third deflection means 61, 71, 6m, 7m, 6r and 7r are arranged lowerable from the same side in the respective sub-strand and also that the sub-strands T 1 to T 3 by means of the outlet Guide 8, 9 are guided back in the direction of the cutting device 4, in the embodiment parallel to the incoming path P. They are before, at or even behind the cutting device 4 deflected, in the representation of FIG. 10 moved up and then on to biasing unit 19.

Figur 11 zeigt die Bahnspreizvorrichtung des dritten Ausführungsbeispiels in einem Zustand, in dem die Bahn P noch ungeschnitten durch die Bahnspreizvorrichtung gefördert werden kann. Sämtliche Träger 101, 10m und 10r sind bis in eine Endposition soweit angehoben, dass die linken Umlenkmittel 51 und 61, die rechten Umlenkmittel 5r und 6r und die Umlenkmittel 6m und 7m des Bahnlängenkompensators die Bahn P nicht berühren. Die linke Lagereinrichtung 3 und die rechte Lageeinrichtung 3 nehmen in Bezug auf die Querrichtung jedoch bereits eine auf die Breite der Bahn P abgestimmte Position ein. In diesem Zustand der Bahnspreizvorrichtung wird die Bahn P eingezogen. Beim Einziehen wird die Bahn P vom Rollenwechsler 1 über die Einlauf-Leiteinrichtung 2 und von dort durch die voneinander abgestellten Schneidrollen der Schneideinrichtungen 4 auf die ersten Umlenkmittel 5 geführt, im ersten Ausführungsbeispiel die Umlenkmittel 5l und 5r und im zweiten Ausführungsbeispiel auf die Umlenkmittel 5l, 5m und 5r. Der Bahnanfang wird von den ersten Umlenkmitteln 5 geradewegs und unbeeinflusst von den heb- und senkbaren Umlenkmitteln bis zur Auslauf-Leiteinrichtung, im ersten Ausführungsbeispiel die einzige Auslaufwalze 8 und im zweiten Ausführungsbeispiel das Paar der Auslaufwalzen 8 und 9, geführt und die jeweilige Auslauf-Leiteinrichtung 8 oder 8, 9 umschlingend zum Vorspannwerk 19, durch den Druckturm 20 bis zu einem nicht dargestellten Wendestangenbereich automatisch eingezogen. Nach dem Einzug bis zum Wendestangenbereich wird die Bahn P bei geringer Geschwindigkeit längs geschnitten. Hierfür werden lediglich die Schneideinrichtungen 4 in die jeweilige Schnittposition gebracht. Nach dem Längsschneiden werden die linken Umlenkmittel 61 und 71, die rechten Umlenkmittel 6r und 7r und das oder die heb- und senkbare(n) Umlenkmittel des Bahnlängenkompensators, im ersten Ausführungsbeispiel das Umlenkmittel 25b und im zweiten Ausführungsbeispiel die Umlenkmittel 6m und 7m, in ihre für das Spreizen und die entsprechende Bahnlängenkompensation vorgesehene Spreiz- bzw. Kompensierposition bewegt, vorzugsweise synchron. Haben die Teilstränge T1, T2 und T3 den Wendestangenbereich erreicht, werden sie weiter bis zu dem Falzapparat oder den mehreren Falzapparaten der Druckmaschine eingezogen. Typischerweise umfasst die Druckmaschine mehrere Rollenwechsler 1, erfindungsgemäße Bahnspreizvorrichtungen und Drucktürme 20. Die weiteren Bahnen P werden entsprechend eingezogen. Nachdem sämtliche Bahnen für eine bestimmte Druckproduktion eingezogen sind, werden die Bahnen bis auf die Geschwindigkeit des Fortdrucks beschleunigt. In der Beschleunigungsphase wird der Druckprozess gestartet. FIG. 11 shows the web spreading device of the third embodiment in a state in which the web P can still be conveyed uncut by the web spreading device. All carriers 101, 10m and 10r are raised to an end position so far that the left deflection means 51 and 61, the right deflection means 5r and 6r and the deflection means 6m and 7m of the web length compensator do not touch the web P. The left bearing device 3 and the right-hand layer device 3, however, already assume a position matched to the width of the web P in relation to the transverse direction. In this state of the web spreading device, the web P is drawn. When drawing the web P is guided by the paster 1 on the inlet guide 2 and from there by the cut off cutting rollers of the cutting devices 4 on the first deflection 5, in the first embodiment, the deflection 5l and 5r and in the second embodiment on the deflection 5l, 5m and 5r. The beginning of the web is guided by the first deflection means 5 straight and unaffected by the liftable and lowerable deflecting means to the outlet guide, in the first embodiment, the single outlet roller 8 and in the second embodiment, the pair of outlet rollers 8 and 9, and the respective outlet guide 8 or 8, 9 wrapped around the biasing unit 19, automatically retracted by the printing tower 20 to a turning bar area, not shown. After feeding to the turning bar area, the web P is cut longitudinally at low speed. For this purpose, only the cutting devices 4 are brought into the respective cutting position. After slitting, the left deflection means 61 and 71, the right deflection means 6r and 7r and the one or more deflecting means of the web length compensator, in the first embodiment, the deflection means 25b and in the second embodiment, the deflection means 6m and 7m, in their for the spreading and the corresponding path length compensation provided spreading or Kompensierposition moves, preferably synchronously. When the sub-strands T1, T2 and T3 have reached the turning bar area, they are further drawn in to the folder or the multiple folders of the printing press. Typically, the printing press comprises a plurality of roll changers 1, web spreading devices and printing towers 20 according to the invention. The further webs P are drawn in accordingly. After all the webs are fed for a given print production, the webs are accelerated to the speed of the production run. In the acceleration phase, the printing process is started.

Nachfolgend werden weitere, gegebenenfalls auch alternative Merkmale offenbart. Dabei wird nur beispielhaft auf die konkreten Ausführungsbeispiele Bezug genommen.Below, further, possibly also alternative features are disclosed. In this case, reference is made only by way of example to the specific embodiments.

Variante 1version 1

Anmerkung: Die nachfolgende Beschreibung beschränkt sich auf den komplexesten Fall der 2fach-Spreizung mit drei gleichgroßen, reduzierten Bahnbreiten.Note: The following description is limited to the most complex case of 2-fold spreading with three equal, reduced web widths.

Die Papierbahn P wird komplett in der Spreizvorrichtung beim autopaster 2fach gespreizt. Dabei wird die Papierbahn P im autopaster lagerichtig eingespannt. Die Papierbahn wird in der Spreizvorrichtung zweimal geschnitten: Einmal zwischen AB und CD und einmal zwischen CD und EF. Der Schnitt ist je nach Spreizmaß (x) entsprechend neu zu setzen. Dazu wird das Messer 4 um mindestens x entsprechend verfahren / versetzt. Sind mehrere Spreizmaße zu realisieren, wird dies motorisch gelöst (Automationsgrad beibehalten). Erschwerend ist, dass sich die beiden Messer 4 jeweils voneinander entfernen müssen, resp. auf sich zu bewegen.The paper web P is completely spread in the spreader 2-fold autopaster. The paper web P is clamped in the correct position in the autopaster. The paper web is cut twice in the spreading device: once between AB and CD and once between CD and EF. The cut is to be reset according to the spreading dimension (x). For this purpose, the knife 4 is moved / offset by at least x. If several spread dimensions are to be realized, this is solved by motor (maintain automation degree). The complicating factor is that the two blades 4 each have to move away from each other, resp. to move on.

Der mittlere Strang T2 wird gerade weitergeführt, die beiden äußeren Stränge T1 und T3 werden um schräggestellte Umlenkmittel 51, 61 und 5r, 6r geführt, die beispielsweise als Umlenkstangen gebildet sind. Durch das Verfahren der Umlenkmittel 51, 61 und 5r, 6r wird ein Spreizmaß x erreicht.The middle strand T2 is just continued, the two outer strands T1 and T3 are guided by inclined deflection means 51, 61 and 5r, 6r, for example, as deflection rods are formed. By the method of the deflection 51, 61 and 5r, 6r an expansion dimension x is achieved.

Die Umlenkmittel 51, 61 und 5r, 6r und pro linker und rechter Gruppe je ein weiteres Umlenkmittel 7l und 7r sind fliegend gelagert. Zu berücksichtigen ist, dass sich die Enden dieser Umlenkmittel genau auf der Schnittkante befinden, da sich die drei, noch nicht gespreizten Stränge T1, T2 und T3 direkt nebeneinander befinden. Zu Beginn des Spreizvorganges wird jeweils die komplette Breite jedes Stranges einzeln geführt. Die Umlenkmittel sowie der jeweils zugeordnete Schlitten 3 werden jeweils gemeinsam mit dem Messer 4 je nach Spreizmaß x verstellt. Sind mehrere Spreizmaße zu realisieren, wird dies motorisch gelöst.The deflection means 51, 61 and 5r, 6r and per left and right group depending on a further deflection means 7l and 7r are cantilevered. It should be noted that the ends of these deflection means are located exactly on the cutting edge, since the three, not yet spread strands T 1 , T 2 and T 3 are directly next to each other. At the beginning of the spreading process, the complete width of each strand is guided individually. The deflecting means and the respective associated carriage 3 are each adjusted together with the knife 4 depending on the spread x. If several spread dimensions are to be realized, this is solved by motor.

Die durch die Spreizung verursachte Längendifferenz zwischen den äußeren Strängen T1, T3 und dem mittleren Strang T2 wird ausgeglichen. Dazu sind in der Spreizvorrichtung entsprechende Leitorgane auf den Spreizschlitten vorgesehen, welche den Strang T2 zusätzlich umlenken. Alternativ wird ein separater Schlitten für den mittleren Strang T2 vorgesehen.The caused by the spread length difference between the outer strands T 1, T 3 and the middle strand T 2 is compensated. For this purpose, corresponding guide elements are provided on the spreading slide, which additionally deflect the strand T 2 in the spreading device. Alternatively, a separate carriage for the middle strand T 2 is provided.

Diese Variante entspricht dem asymmetrischen Spreizen, welche in der bereits realisierten Spreizvorrichtung möglich ist. Tests ergaben folgende Punkte:

  1. 1. Bahnlängendifferenz kann nur mit langsamem Einziehen ausgeglichen werden (Zeitverlust),
  2. 2. Bahnspannung ist in dieser Zeit entsprechend different.
This variant corresponds to the asymmetric spreading, which is possible in the already realized spreading device. Tests showed the following points:
  1. 1. web length difference can be compensated only with slow feeding (loss of time),
  2. 2. Web tension is correspondingly different in this time.

Ein Testbericht liegt nicht vor. Das asymmetrische Spreizen wird in der heutigen Spreizvorrichtung zur Korrektur von Bahnverlaufsfehlern benutzt (bis ca. 2 cm).A test report is not available. The asymmetric spreading is used in today's spreading device for correcting trajectory errors (up to about 2 cm).

Vorteile:

  • ● Symmetrisches Drucken (Panoramaplatten)
    • logisches, symmetrisches Einstellen der Farbschrauben,
    • regelmäßige Shuttereinstellung,
    • die Wendestangen können ohne Einschränkungen wie bei einer normalen Produktion benutzt werden,
    • als Haupttrichter eignet sich der mittlere Trichter (Bahnzugverteilung)
  • ● Komplettes Spreizen direkt beim autopaster → "Bearbeitung" der Papierbahn an einem Ort (vereinfachte Steuerung, da Steuerung am autopaster angegliedert)
Advantages:
  • ● Symmetrical printing (panoramic panels)
    • logical, symmetrical adjustment of the color screws,
    • regular shutters setting,
    • the turning bars can be used without restrictions as in a normal production,
    • the main funnel is the middle funnel (web tension distribution)
  • ● Complete spreading directly at the autopaster → "processing" of the paper web in one place (simplified control, since control is attached to the autopaster)

Untervariantesubvariant

Um die aufwändige Konstruktion zu vereinfachen, wird die Spreizvorrichtung auf ein einziges Spreizmaß fixiert. Dies macht eine motorische Verschiebung des Messers und der Umlenkstangen sowie des Spreizschlittens (seitwärts) überflüssig. Die Konstruktion ist jener der 4/2-Spreizvorrichtung ähnlich.In order to simplify the complex construction, the spreading device is fixed to a single spread. This makes a motor displacement of the blade and the deflection bars and the spreading slide (sideways) superfluous. The construction is similar to that of the 4/2 spreader.

Variante 2Variant 2

Die nachfolgende Beschreibung beschränkt sich auf den komplexesten Fall: 2fach-Spreizung mit 3 gleichgroßen, reduzierten Bahnbreiten.The following description is limited to the most complex case: 2-fold spreading with 3 equal, reduced web widths.

Abweichend zu Variante 1 wird in der Spreizvorrichtung nur ein Strang von der Papierbahn abgeschnitten und gespreizt. Die zweite Spreizung wird durch die Wendestangen realisiert.Deviating from variant 1, only one strand is cut off from the paper web and spread in the spreading device. The second spread is realized by the turning bars.

Das Messer in dieser Variante der Spreizvorrichtung ist gemäß Spreizmass x verschiebbar. Vereinfachend zu Variante 1 ist, dass nur ein Messer zu verschieben ist. Die Umlenkstangen enden wiederum am Schnitt. Beide Spreizschlitten sind seitlich verschiebbar (siehe Beschreibung zu Variante 1). Die Umlenkstangen sind asymmetrisch und in verschiedenen Winkeln ausgeführt, damit keine Bahnlängendifferenz auftritt. Die erforderliche Länge der Umlenkstangen für den breiteren Strang kann mehr als 1500mm betragen. Dies setzt eine entsprechende Vergrößerung der konstruktiven Dimensionen voraus. Die Führungen sind wegen der Krafteinwirkungen vorzugsweise entsprechend verstärkt (vergrößert).The knife in this variant of the spreading is displaceable x according to Spreizmass. Simplifying to variant 1 is that only one knife has to be moved. The deflecting rods in turn end at the intersection. Both expansion slides are laterally displaceable (see description of variant 1). The deflection rods are asymmetrical and designed at different angles so that no track length difference occurs. The required length of the deflection rods for the wider strand may be more than 1500mm. This requires a corresponding increase in the structural dimensions. The guides are preferably amplified (enlarged) because of the force effects.

Der doppelt breite Strang wird um das doppelte Spreizmaß verschoben.The double-width strand is shifted by twice the spreading dimension.

Der schmale Strang wird wie bei Variante 1 symmetrisch durch das Druckwerk geführt. Der doppelt breite Strang wird entsprechend versetzt durchgeführt. Nach dem Druckwerk wird der doppelt breite Strang mittig geschnitten und mit den Wendestangen durch Wenden und Kehren gespreizt.The narrow strand is guided symmetrically as in variant 1 through the printing unit. The double-wide strand is carried out offset accordingly. After the printing of the double wide strand cut in the middle and spread with the turning bars by turning and sweeping.

Vorteile:

  • ● nur ein Messer in der Spreizvorrichtung
Advantages:
  • ● only one knife in the spreading device

Nachteile:

  • ● die technische Realisierung für mehrere Spreizmaße ist wegen der motorischen Verschiebung vieler Elemente sehr aufwändig und entsprechend teuer
  • ● asymmetrische Shutter
  • ● asymmetrisches Einstellen der Farbschrauben (innerhalb AB und CD)
  • ● Spreizung über mehrere Bausteine verteilt. Steuerung daher aufwändiger
Disadvantage:
  • ● The technical realization for several spread dimensions is very complicated and correspondingly expensive due to the motorized displacement of many elements
  • ● asymmetric shutter
  • ● asymmetrical adjustment of the color screws (within AB and CD)
  • ● Spread distributed over several blocks. Control therefore more complex

Einschränkungen seitens der Wendestangen:Restrictions on the turning bars:

Das minimale Spreizmaß bei der Wendestange ist aus konstruktiven Gründen 55 mm.The minimum expansion of the turning bar is 55 mm for structural reasons.

Die Bahn EF wird gerade durch die Wendestangen durchgeführt, AB und CD werden gewendet/gekehrt. Der Haupttrichter wird daher jener der Bahn EF sein.The orbit EF is currently being performed by the turning bars, AB and CD are turned / swept. The main hopper will therefore be that of the web EF.

Variante 3Variant 3

Das Spreizen wird auch für 6/2 auf 4 Seiten beschränkt. Dazu wird eine für 4/2 ausgeführte Spreizvorrichtung entweder auf AB-CD oder auf CD-EF montiert. Das Messer befindet sich fix auf der Kante zwischen B und C beziehungsweise zwischen D und E. Für eine Spreizproduktion kann nun im autopaster lediglich eine 4seitenbreite Papierbahn eingespannt werden. Das Spreizen wird wie bekannt durchgeführt.The spreading is also limited to 6/2 on 4 pages. For this purpose, a spreading device designed for 4/2 is mounted either on AB-CD or on CD-EF. The knife is located fixed on the edge between B and C or between D and E. For a spread production can now be clamped in the autopaster only a 4-page wide paper web. The spreading is carried out as known.

Eine Papierbahn maximaler Breite PB wird nicht gespreizt. Diese Papierbahn wird auch nicht durch die Spreizvorrichtung geführt, was bedeutet, dass sich der Bahneinzug von Spreizproduktion und Nicht-Spreizproduktion unterscheidet.A paper web of maximum width PB is not spread. Also, this web is not passed through the spreader, which means that the web feeder is different from spreader and non-spreader.

Vorteile:

  • ● Einfache, bestehende Konstruktion der Spreizvorrichtung
  • ● Keine technischen, unbekannten Risiken
  • ● Symmetrisches Drucken (Panoramaplatten)
    • logisches, symmetrisches Einstellen der Farbschrauben
    • regelmäßige Shuttereinstellung
    • die Wendestangen können ohne Einschränkungen wie bei einer normalen Produktion benutzt werden
    • als Haupttrichter eignet sich der mittlere Trichter (Bahnzugverteilung)
  • ● Komplettes Spreizen direkt beim autopaster → "Bearbeitung" der Pa pierbahn an einem Ort (vereinfachte Steuerung)
Advantages:
  • ● Simple, existing design of the spreading device
  • ● No technical, unknown risks
  • ● Symmetrical printing (panoramic panels)
    • logical, symmetrical adjustment of the color screws
    • regular shutters setting
    • The turner bars can be used without restrictions as in a normal production
    • the main funnel is the middle funnel (web tension distribution)
  • ● Complete spreading directly at the autopaster → "processing" the paper web in one place (simplified control)
