Description

Die Erfindung betrifft eine Papierbahnführung in Rollenrotationsdruckmaschinen gemäß dem kennzeichnenden Teil des Anspruchs 1.The invention relates to a paper web guide in web-fed rotary printing presses according to the characterizing part of claim 1.

Papierbahnführungen in Rollenrotationsdruckmaschinen sind allgemein bekannt. Hierbei sind die Papierleitwalzen lediglich etwas breiter als die maximale in den Druckwerken verarbeitbare Papierbahnbreite. Sollen mehrere Papierbahnlagen aus mehreren Papierbahnsträngen aus einer oder mehreren Papierbahnen gebildet werden, so ist pro Papierbahnstrang ein Falztrichter vorgesehen, der jeweils den Papierbahnstrang einer Papierbahnlage längsfalzt. Diese Papierbahnlagen werden im Falzapparat in gewünschter Weise übereinandergelegt, zu Sektionen quergeschnitten und anschließend zu Produkten gefalzt, so daß z. B. innerhalb einer Zeitungssektion eine Tabloid-Sektion zu liegen kommt.Paper web guides in web-fed rotary printing machines are generally known. The paper guide rollers are only slightly wider than the maximum paper web width that can be processed in the printing units. If several paper web layers are to be formed from several paper web strands from one or more paper webs, a folding former is provided for each paper web strand, each of which folds the paper web strand of a paper web layer longitudinally. These paper web layers are placed in the folder in the desired manner, cross-cut into sections and then folded into products, so that, for. B. a tabloid section comes to rest within a newspaper section.

Bei den herkömmlichen Rollenrotationsdruckmaschinen beträgt die maximale Plattenzylinderlänge die Breite von vier Seiten, und der Walzenstuhl mit der Papierbahnführung ist auf diese Papierbahnbreite ausgelegt.With conventional web-fed rotary printing presses, the maximum plate cylinder length is four pages wide, and the roller mill with the paper web guide is designed for this paper web width.

Zum Herstellen von Produkten, die aus einem Zeitungs- und einem Magazinteil bestehen, werden im Falzapparat drei oder vier Einlauftrichter benötigt. Hierbei sind die Trichter je paarweise übereinander angeordnet, um die Papierbahnen wahlweise zusammenführen zu können, zu "mischen". Dieses Übereinander-Anordnen der Trichter bedingt jedoch eine hohe Bauhöhe der Maschine.To make products that consist of a newspaper and a magazine part, three or four infeed hoppers are required in the folder. Here, the funnels are arranged in pairs one above the other so that the paper webs can be brought together to "mix". This stacking of the funnels, however, requires a high overall height of the machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Papierbahnführung zu schaffen, mit der ein einfaches "Mischen" der bedruckten Papierbahnen in einer Rollenrotationsdruckmaschine möglich ist, ohne daß Trichter in mehreren Etagen übereinander angeordnet zu werden brauchen.The invention has for its object to provide a paper web guide with which a simple "mixing" of the printed paper web is possible in a web-fed rotary printing press without the need to arrange funnels on several levels one above the other.

Diese Aufgabe wird durch den Gegenstand des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the subject matter of the characterizing part of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß bedruckte Papierbahnen gemischt werden , können, ohne sie zu umführen, d. h. von einer Trichterebene auf eine andere führen zu müssen. Der Papiereinlauf in den Falzapparat wird niedriger, und die Trichter liegen auf gleicher Höhe.The advantages that can be achieved with the invention are, in particular, that printed paper webs can be mixed without having to move them around, ie. H. from one hopper level to another. The paper feed into the folder becomes lower and the hoppers are at the same height.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

  • Fig. 1 ein Druckwerk mit erfindungsgemäßer aufgesetzter Papierbahnführung,
  • Fig. 2 einen Papiereinlauf in einen Falzapparat über drei Trichter, und
  • Figg.3 a-e eine Darstellung der Mischmöglichkeiten mit der erfindungsgemäßen Papierbahnführung.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it
  • 1 is a printing unit with attached paper web guide according to the invention,
  • Fig. 2 shows a paper inlet in a folder over three funnels, and
  • 3 ae a representation of the mixing possibilities with the paper web guide according to the invention.

Es ist allgemein bekannt, zum Führen einer Papierbahn aus dem Druckwerk in den Falzapparat oder zu anderen Druckwerken oberhalb der Druckwerke Papierbahnführungen vorzusehen. Diese Papierbahnführungen bestehen im wesentlichen aus Papierleitwalzen und Wendestangen. Oberhalb des Falzapparates sind dann eine entsprechende Anzahl von Papierbahn-Einlaufwalzen angeordnet. (Siehe auch DE-OS 25 32 168).It is generally known to provide paper web guides for guiding a paper web from the printing unit into the folder or to other printing units above the printing units. These paper web guides essentially consist of paper guide rollers and turning bars. A corresponding number of paper web infeed rollers are then arranged above the folder. (See also DE-OS 25 32 168).

In einem an sich bekannten Druckwerk 1 einer Rollenrotationsdruckmaschine sind bekannte Gummituch-, Gegendruckzylinder 10, 5 und Formzylinder 2 gelagert. Die Zylinder 2, 5, 10 sind z. B. als herkömmliche Zylinder ausgebildet, d. h. sie sind vier Seitenbreiten "d" lang. Auf jedes Druckwerk 1 ist eine Papierbahnführung 3 aufgesetzt. Sie besteht in bekannter Weise aus den Seitenrahmen 4 und 6, die auf die Seitengestelle 7 und 8 der Druckwerke 1 aufgesetzt und in den Papierleitwalzen 11 drehbar gelagert sind. Eine jede Papierbahn 9 wird, aus dem Druckwerk 1 herausgetreten, über eine eigene Papierbahnführung 3 zu den Trichtervoreinlaufwalzen 13 und von da über Längsfalztrichter 14, 15, 16 in ein Falzwerk 20 geführt.Known blanket, impression cylinders 10, 5 and forme cylinders 2 are mounted in a printing unit 1 of a web-fed rotary printing press known per se. The cylinders 2, 5, 10 are z. B. formed as a conventional cylinder, ie they are four side widths "d" long. A paper web guide 3 is placed on each printing unit 1. It consists in a known manner of the side frames 4 and 6, which are placed on the side frames 7 and 8 of the printing units 1 and are rotatably mounted in the paper guide rollers 11. Each paper web 9 is etreten g from the printing unit 1 out via a separate web guide 3 to the Trichtervoreinlaufwalzen 13 and from there via longitudinal formers 14, 15, 16 in a folding unit 20th

Die Papierbahnführungen 3 der Druckwerke 1 liegen in verschiedenen Ebenen übereinander und bestehen aus Papierleitwalzen 11 und Wendestangen 12 bzw. 18. Im Gegensatz zu den herkömmlichen Papierbahnführungen, in denen die Länge der Papierleitwalzen 11 auf die maximal verarbeitbare Breite "a" der Papierbahn 9 abgestimmt ist, erstrecken sich bei der erfindungsgemäßen Papierbahnführung 3 die Papierleitwalzen 11 über eine innere Breite "b" des Druckwerkes wesentlich hinaus, z. B. um das Maß "c" einer halben, maximal im Druckwerk 1 verarbeitbaren Papierbahnbreite "a". Diese Breite "b+c" behalten die Papierbahnführungen 3 bis zu den Trichtervoreinlaufwalzen 13 bei. Den Trichtervoreinlaufwalzen 13 folgen mindestens drei Längsfalztrichter 14, 15, 16, die auf gleicher Höhe nebeneinander angeordnet sind. Bei jeder Papierbahnführung 3 ist zwischen Druckwerk 1 und Trichtervoreinlaufwalze 13 und einem angetriebenen, abhebbaren Längsschneidmesser 17 eine Doppelwendestange 18The paper web guides 3 of the printing units 1 lie one above the other in different planes and consist of paper guide rollers 11 and turning bars 12 and 18, in contrast to the conventional paper web guides in which the length of the paper guide rollers 11 is matched to the maximum processable width "a" of the paper web 9 , In the paper web guide 3 according to the invention, the paper guide rollers 11 extend substantially beyond an inner width "b" of the printing unit, for. B. by the dimension "c" of a half, maximum paper web width "a" that can be processed in the printing unit 1. The paper web guides 3 maintain this width "b + c" up to the hopper feed rollers 13. The former feed rollers 13 are followed by at least three longitudinal folding hoppers 14, 15, 16, which are arranged next to one another at the same height. In each paper web guide 3 there is a double turning bar 18 between the printing unit 1 and the hopper feed roller 13 and a driven, removable longitudinal cutting knife 17

vorgesehen. Sie erlaubt eine Parallelverschiebung der von der Papierbahn 9 mittels des Längsschneidmessers 17 abgetrennten Teilpapierbahn 19 (z. B. halbe Papierbahnbreite "c") zu der Restpapierbahn 21. Jede der beiden Doppelwendestangen 18 ist für sich allein über die Breite "c+b" der Papierbahnführung verschiebbar und arretierbar auf an den Seitenrahmen 4, 6 befestigten Führungsträgern angeordnet.intended. It allows a parallel displacement of the partial paper web 19 (z. B. half paper web width "c") separated from the paper web 9 by means of the slitting knife 17 to the residual paper web 21. Each of the two double turning bars 18 is by itself over the width "c + b" of Paper web guide slidably and lockably arranged on guide carriers attached to the side frames 4, 6.

Durch die erfindungsgemäße Einrichtung ist es möglich, die Teilpapierbahnen 19, 21 der Papierbahn 9 vorwählbar auf der Ebene der entsprechenden Papierbahnführung wahlweise auf einen der nebeneinander angeordneten Längsfalztrichter 14, 15, 16 zu legen, und damit die Bahnen eines Papierstranges zu mischen, wie aus den Figuren 3 a-e ersichtlich wird.By means of the device according to the invention, it is possible to selectively place the partial paper webs 19, 21 of the paper web 9 selectively on the level of the corresponding paper web guide on one of the longitudinal folding funnels 14, 15, 16 arranged next to one another, and thus to mix the webs of a paper strand, as in FIGS Figures 3 ae can be seen.
