Die Bahn 1 bzw. die Teilbahnen 16 bis 19 sind also unter Aufrechterhaltung einer Bahnspannung eingespannt und werden gezogen.Seen in the direction of production E of the paper web 1, is in the first path z. B. A behind the Device 3 for reducing the tensile strength of the Lane 1 or partial lanes 16; 17; 18; 19 and before Forwarding systems 7; 8 a device 13; 21 to 24 to grasp the start of a web 1 or Partial web 16 to 19 on its top and / or Underside and its subsequent deflection into one second running path, e.g. B. B or C and back. E.g. of paths A + C only in path A or from path A + B back to path A or from Running path A + C to running path A + B or from running path A + B after running path A + C etc. The path to be redirected or partial web is in this phase in two from each other spaced devices under tension clamped. This happens e.g. B. between two Pull roller pairs, between a pull roller pair and Cylinders (e.g. blanket cylinders) of a printing unit, between cylinders of two spaced printing units. The web 1 or the sub-webs 16 to 19 are therefore under Maintaining a web tension and are drawn.

Durch die eben beschriebenen Maßnahmen kann in besonders einfacher Weise durch Veränderung der Anzahl der Teilbahnen je Laufpfad (A; B; C) und damit die Zusammensetzung und Seitenzahl der Signaturen gewählt werden, natürlich in Abhängigkeit von der Belegung der Druckeinheiten. Hierzu sind dann an sich bekannte Bahnüberführungen notwendig.The measures just described can in particular simply by changing the number of Partial tracks per running path (A; B; C) and thus the Composition and number of pages of the signatures selected depending on the occupancy of the Pressure units. For this purpose, known ones are then known Railway overpasses necessary.

Es spielen sich folgende Vorgänge ab:
Die eingespannte Papierbahn 1 bzw. Teilpapierbahnen 16 bis 19 bewegen sich jeweils entlang eines Laufpfades z. B. A; B; C. Sie werden durch Krafteinwirkung durch die Einrichtung zum Umlenken einer Bahn 13; 21 bis 24 auf ihre Ober- und/oder Unterseite aus ihrem Laufpfad z. B. A in einen anderen Laufpfad z. B. Laufpfad B bzw. Laufpfad C gezogen. Da die Einrichtung zum Umlenken 13; 21 bis 24 eine Einrichtung zum Festhalten 13, 44 und Fördern 13; 44 der Bahn/Teilbahn aufweist, wird also die festgehaltene Bahn 1; 16 bis 19 gleichzeitig entlang des bisherigen Laufpfades z. B. Laufpfad A und des neuausgewählten Laufpfades z. B. Laufpfad C bewegt und an einer in die Bahn 1 bzw. Teilbahn 16 bis 19 eingebrachten Quersollbruchstelle/Sollreißlinie (Querperforation oder Wasserspur) getrennt. Dies geschieht, weil durch die auf die Bahn/Teilbahn ausgeübte Zugkraft die Reißfestigkeit an der Quersollbruchstelle überschritten wurde. Die betroffene Bahn/Teilbahn wird durchgehend so auseinander getrennt, daß ein "neues" Bahnende 5 und ein "neuer" Bahnanfang 15 entstehen. Die Bahn 1 bzw. Teilbahnen 16 bis 19 wird zusammen mit seinem "neuen" Ende 5 z. B. von Zugwalzen, Druckwerken usw. entlang des bisherigen Laufpfades z. B. gezogen. Der "neue" Bahnanfang 15 der Bahn 1 bzw. der Teilbahnen 16 bis 19 und diese selbst werden von der/den Einrichtungen zum Umlenken 13; 44 festgehalten und entlang den neuausgewählten Laufpfaden, z. B. C bewegt und schließlich an ein Weiterleitsystem z. B. 9 abgegeben und an einen vorgesehenen Zielort, z. B. ein Zugwalzenpaar, Druckspalt einer Druckeinheit transportiert und von ihnen übernommen.The following processes take place:
The clamped paper web 1 or partial paper webs 16 to 19 each move along a running path z. B. A; B; C. They are applied by force through the device for deflecting a web 13; 21 to 24 on their top and / or bottom from their running path z. B. A in another path z. B. Running path B or running path C is drawn. Since the device for deflecting 13; 21 to 24 a device for holding 13, 44 and conveying 13; 44 of the web / partial web, so the captured web 1; 16 to 19 simultaneously along the previous path z. B. Path A and the newly selected path z. B. Running path C is moved and separated at a web break 1 or partial web 16 to 19 introduced cross break / predetermined tear line (cross perforation or water trail). This happens because the tensile force exerted on the web / partial web has exceeded the tensile strength at the transverse set point. The affected web / partial web is continuously separated so that a "new" web end 5 and a "new" web start 15 are created. The web 1 or partial webs 16 to 19 together with its "new" end 5 z. B. of drawing rollers, printing units, etc. along the previous path z. B. pulled. The "new" beginning of the path 15 of the path 1 or the partial paths 16 to 19 and these themselves are used by the deflection device (s) 13; 44 held and along the newly selected paths, e.g. B. C moves and finally to a relay system z. B. 9 and delivered to an intended destination, for. B. transported a pair of pull rollers, pressure nip of a printing unit and taken over by them.

Die Sollbruchstelle/Sollreißstelle kann eigentlich in ihrer Form nahezu beliebig gestaltet werden.The predetermined breaking point / breaking point can actually be in their shape can be designed almost arbitrarily.

Sie kann z. B. als spitzwinklige Spitze in Form eines rechtwinkligen Dreiecks ausgebildet werden, beginnend an einer der beiden Seitenkanten; aber auch als einfacher, nichtschräger, d. h. gerader Abriß.You can e.g. B. as an acute-angled tip in the form of a right triangle are formed starting at one of the two side edges; but also as a simple one, non-slayer, d. H. straight demolition.

Die Kammern 26 bis 29 weisen an ihrer breiteren Grundseite 31, in Produktionslaufrichtung E gesehen, links und rechts Führungen 42; 43 für ein umlaufendes Saugband 44 auf. Das Saugband 44 hat über seine gesamte Länge und Breite voneinander beabstandete Löcher 46, 47, 48, 49, 50, welche sich mit in der Grundseite 31 der Kammern 26 bis 29 eingebrachten Langlöchern 52; 53; 54; 55; 56 zeitweise abwechselnd überdecken. The chambers 26 to 29 have their wider Base page 31, seen in the direction of production E, left and right guides 42; 43 for a revolving Suction belt 44 on. The suction belt 44 has its entire Holes 46, 47 spaced apart in length and width 48, 49, 50, which are in the base 31 of the Chambers 26 to 29 introduced elongated holes 52; 53; 54; 55; 56 cover alternately at times.

Das Saugband 44 ist über beide Bandrollen 39; 41 geführt. Die Bandrolle 39 wird z. B. so angetrieben, daß das Saugband 44 an seiner bahnnahen Seite mit Maschinengeschwindigkeit und in Produktionsrichtung E fördert. Dieser Antrieb erfolgt z. B. über Zahnriemen von der Einrichtung 3 aus, mittels z. B. eines drehzahlregelbaren Elektromotors.The suction belt 44 is on both belt rollers 39; 41 guided. The tape roll 39 is z. B. driven so that the suction belt 44 on its side near the web Machine speed and in production direction E promotes. This drive takes place, for. B. via timing belt from the device 3, by means of z. B. one speed-adjustable electric motor.

Jede Kammer 26 bis 29 hat seitlich jeweils einen Stutzen 58, an den Luftleitungen 60; 61; 62; 63 angeschlossen sind. Sie stehen wahlweise mit einer Saugluft- oder einer Druckluftquelle in Verbindung. So sind eine Mehrzahl von Kammern 26; 27; 28 mit Saugluft und mindestens die letzte Kammer 29 mit Druckluft beaufschlagbar.Each chamber 26 to 29 has a neck on the side 58, on the air lines 60; 61; 62; 63 connected are. They are optionally available with a suction or a compressed air source. So are one Plurality of chambers 26; 27; 28 with suction air and at least the last chamber 29 with compressed air acted upon.

Das auslaufende Ende 36 der Saugbandstation 21 ist höhenverstellbar, z. B. mittels eines seitengestellfesten Arbeitszylinders 64, dessen Gegenlager 45 an einer seitengestellfesten Traverse 51 gelagert ist.The outgoing end 36 of the suction belt station 21 is height adjustable, e.g. B. by means of a side frame fixed working cylinder 64, the Counter bearing 45 on a cross member 51 fixed to the side frame is stored.

Nach einer anderen, erfindungsgemäßen Ausführungsvariante kann die Einrichtung zum Umlenken 13; 21 bis 24 mit einer Einrichtung zum Festhalten und Fördern auch als rotierbare Saugwalze 13 ausgebildet sein. Ihr wird über eine nicht dargestellte Dreheinführung Saugluft zugeführt. Dabei kann jeweils die gesamte Länge der Saugwalze 13 entsprechend einer Breite der Bedruckstoffbahn 1 oder nur eine oder mehrere Teillängen entsprechend der Breite einer Teilbahn 16, 17, 18 oder 19 mit Saugluft beaufschlagt werden. Dabei sind etwa 270° des Innenumfanges der Saugwalze 13 mit einem abdichtenden Mantel 20 überdeckt, so daß die Saugluft nur an dem durch die Bahn 1 oder die entsprechenden Teilbahnen an der Saugwalze 13 anliegenden Umfang von einem Winkel Beta von ca. 90° wirksam wird. Aus einer achsparallelen Scheitellinie 71 (Linie an der ein Laufrichtungswechsel der Bahn 16 aus einer Richtung - z. B. horizontale Richtung - in eine andere Richtung - z. B. vertikale Richtung - erfolgt) auf dem Mantel reißt die Bahn 16 quer entlang der Solltrenn-/Reißlinie 68 auf. Der vorauslaufende Teil der Teilbahn 16 läuft weiter über die Papierleitwalzen 9; 11 im Laufpfad B. Der abgerissene Teil der Teilbahn mit dem neuen Bahnanfang 15 läuft weiter entlang des Laufpfades A und von da ggf. zu einem anderen Laufpfad, z. B. Laufpfad C ein. Dabei wird der "neue" Anfang 15 der Teilbahn 16 im Bereich der vorletzten Kammer 28 noch angesaugt und im Bereich der letzten Kammer 29 mittels Blasluft abgestoßen und so zwischen die oberen und unteren Bänder eines Weiterleitsystemes 7; 8 gebracht und von da in einen vorgewählten Laufpfad, z. B. Laufpfad C.According to another embodiment variant according to the invention, the Deflection device 13; 21 to 24 with one Device for holding on and promoting also as rotatable suction roller 13 may be formed. Your will a rotary inlet suction air, not shown fed. The entire length of the Suction roll 13 corresponding to a width of the Printing material web 1 or only one or more partial lengths corresponding to the width of a partial web 16, 17, 18 or 19 with suction air. Here are about 270 ° of the inner circumference of the suction roll 13 with a sealing jacket 20 covers, so that the suction air only on the one by lane 1 or the corresponding Partial webs adjacent to the suction roller 13 an angle beta of approximately 90 ° is effective. From one Axis parallel apex line 71 (line on the one Change of direction of web 16 from one direction - z. B. horizontal direction - in another direction - z. B. vertical direction - takes place) tears on the coat the web 16 transversely along the predetermined separation / tear line 68 on. The leading part of the partial web 16 runs continue on the paper guide rollers 9; 11 in path B. The demolished part of the partial web with the new one Start of path 15 continues along path A and thence to another running path, e.g. B. Running path C on. The "new" beginning 15 of the partial web 16 in the Area of the penultimate chamber 28 still sucked in and Area of the last chamber 29 by means of blown air repelled and so between the top and bottom bands a forwarding system 7; 8 brought and from there in a preselected running path, e.g. B. Running path C.

Das Verfahren zum Quertrennen und Richtungsändern einer laufenden Papierbahn läuft wie folgt ab: Eine in Produktionslaufrichtung E laufende ganzbreite Papierbahn 1 wird mittels der Längstrenneinrichtung 2 in vier 1/4-breite Teilpapierbahnen 16 bis 19 längsgetrennt und (über die Papierleitwalzen 9; 7) in einem ersten Laufpfad A geführt. Nachfolgend wird z. B. die linke Teilbahn 16 mittels einer Vorrichtung 3 zum Vermindern der Reißfestigkeit der Bahn, z. B. der Querperforiereinrichtung 3, mit einer in einem vorbestimmten Winkel ± Alpha, z. B. von 0° bis 60° - vorzugsweise 45° - zur Seitenkante 66 oder 67 bzw. der Teilpapierbahn 16 mit einer Solltrenn-/Reißlinie 68 oder 69 in Form z. B. einer Querperforationslinie oder Quer-Wasserspur versehen. Nach dem Trennen der Bahn 1 bzw. Teilbahn entsteht ein "neues" Bahnende 5 und ein nachlaufender "neuer" Bahnanfang 15 der Bahn 1 bzw. Teilbahn 16.The procedure for cross cutting and changing the direction of a running paper web runs like follows from: A running in the direction of production E. full-width paper web 1 is by means of Longitudinal separator 2 in four 1/4 width Partial paper webs 16 to 19 longitudinally separated and (via the Paper guide rollers 9; 7) in a first running path A guided. In the following, e.g. B. the left partial web 16 by means of a device 3 for reducing the Tensile strength of the web, e.g. B. the Cross perforating device 3, with one in one predetermined angle ± alpha, e.g. B. from 0 ° to 60 ° - preferably 45 ° - to the side edge 66 or 67 or the partial paper web 16 with a predetermined separation / tear line 68 or 69 in the form of z. B. a cross perforation line or Provide transverse water trail. After separating lane 1 or partial web creates a "new" web end 5 and a trailing "new" start of path 15 of path 1 or Section 16.

(+) Alpha heißt, der Winkel Alpha ist bezogen auf die rechte Seitenkante 67 der Teilbahn 16; (-) Alpha heißt, der Winkel Alpha ist bezogen auf die linke Seitenkante 66 der Teilbahn 16.(+) Alpha means that the angle Alpha is related to the right side edge 67 of partial web 16; (-) Alpha means the angle alpha is related to the left side edge 66 of sub-track 16.

Die über der Teilbahn 16 angeordnete Saugbandstation 21, z. B. in geringem Abstand f = ein Millimeter, wird mit Druck- und Saugluft beaufschlagt. Die ersten Kammern 26 bis 28 werden mit Saugluft und zumindest die letzte Kammer 29 wird mit Blasluft beaufschlagt. Die Bahn/Teilbahn wird angesaugt und am Saugband 44 festgehalten. The suction belt station 21 arranged above the partial web 16 z. B. at a short distance f = one millimeter, with Compressed and suction air acted on. The first chambers 26 to 28 with suction air and at least the last one Blown air is applied to chamber 29. The Web / partial web is sucked in and on the suction belt 44 recorded.

Die Bahn/Teilbahn 16 soll aus Laufpfad A in Laufpfad C umgelenkt werden. Die z. B. sich im Laufpfad A bewegende Bahn/Teilbahn 16 hat eine Geschwindigkeit, die der Umfangsgeschwindigkeit des Saugbandes 21 gleich ist. Das Saugband 21 saugt die umzulenkende Bahn 16 so an, daß sie möglichst nicht schlupft und versucht sie in den neuen vorgewählten Laufpfad, z. B. C zu bewegen (zu ziehen). D. h. die Bahn 16 wird zeitweise sowohl im Laufpfad A und in den neuen Laufpfad C bewegt. Hierdurch steigt die auf die Bahn 16 ausgeübte Zugspannung so weit an, bis die künstlich erzeugte Verminderung der Reißfestigkeit der Bahn 16 überschritten wird und die Bahn 16 quer entlang einer vorherbestimmten Sollbruchlinie (Reißlinie) getrennt wird. Ein Teil der Bahn 16 läuft weiter im Laufpfad A und der abgerissene Teil wird im Laufpfad B weitertransportiert.The lane / partial lane 16 is intended to run from path A into path C. be redirected. The z. B. moving in path A. Lane / partial lane 16 has a speed that the The peripheral speed of the suction belt 21 is the same. The Suction belt 21 sucks the web 16 to be deflected so that try not to slip and try them in the new preselected running path, e.g. B. C to move (to pull). I.e. the web 16 is temporarily both in Running path A and moved to the new running path C. hereby the tensile stress exerted on the web 16 rises so far until the artificially generated reduction in Tear strength of the web 16 is exceeded and the Lane 16 transversely along a predetermined one Breaking line (tear line) is separated. A part of Lane 16 continues in path A and the torn off Part is transported on in path B.

Nach Abschluß des Quertrenn- und Richtungsänderungsvorganges wird die Luftzufuhr beendet und die Saugbandstation 21 mittels des Arbeitszylinders 64 aus der Nähe der Papierbahn 1 entfernt, d. h. hochgeschwenkt.After completing the cross separator and Direction change process stops the air supply and the suction belt station 21 by means of the working cylinder 64 removed from the vicinity of paper web 1, d. H. swung.

Es ist auch möglich, eine oder mehrere andere Teilbahnen in einen anderen Laufpfad nach unten zu übergeben. Dies kann durch die Verstellung der Kammern 26 bis 29 und Saugbandstationen 21 bis 24 so zueinander erfolgen, daß die Saugbänder 21 anstatt eine konvexe Form nachzubilden, nur eine konkave Form nachbilden. It is also possible to have one or more other partial webs to pass down another path. This can by adjusting the chambers 26 to 29 and Suction belt stations 21 to 24 take place so that each other the suction belts 21 instead of a convex shape replicate, just replicate a concave shape.

Ein Trennen der Papier- oder Teilbahnen erfolgt also durch Festhalten und Richtungsändern.The paper or partial webs are thus separated by holding on and changing direction.

Es kann aber auch eine Vorrichtung zum vollständigen Durchtrennen der Papierbahn 1, 16 bis 19 vorgesehen sein. Sie besteht z. B. aus einem auf- und ab bewegbaren Schwert mit einem Messer, das mit einer gestellfesten Gegenschneide zusammenwirkt. Die Papierbahn 1, 16 bis 19 wird angehalten oder bewegt sich langsam und wird dann quergeschnitten. Während dieses Vorganges wird die Papierbahn 1, 16 bis 19 von Saugbändern 44 über Kammern 26, 27, 28, 29, wie sie oben beschrieben wurden, festgehalten. Es sind zwei, in Produktionsrichtung gesehen, hintereinander angeordnete antreibbare Saugbändersysteme 44 vorgesehen. Zwischen ihnen bewegt sich das Messer auf und ab und schneidet die Papierbahn 1, 16 bis 19 quer. Hierbei entsteht ein neues Bahnende 5 und ein neuer Bahnanfang 15. Das neue Bahnende 5 wird vom vorderen Saugbändersystem 44 gehalten und weitertransportiert. Der neue Bahnanfang 15 wird vom hinteren Saugbändersystem 44 (in Produktionslaufrichtung E gesehen) gehalten und (schließlich) weitertransportiert. But it can also be a device for complete Cutting the paper web 1, 16 to 19 provided his. It consists e.g. B. from an up and down movable Sword with a knife with a fixed one Shear bar interacts. Paper web 1, 16 to 19 is stopped or moves slowly and then cut crosswise. During this process, the Paper web 1, 16 to 19 of suction belts 44 over chambers 26, 27, 28, 29 as described above, recorded. There are two, in the direction of production seen, drivable arranged one behind the other Suction belt systems 44 are provided. Moved between them the knife goes up and down and cuts the paper web 1, 16 to 19 across. This creates a new web end 5 and a new path start 15. The new path end 5 becomes held by the front suction system 44 and transported. The new path start 15 is from the rear Suction belt system 44 (in the direction of production E seen) held and (finally) transported on.
