Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Rollendruckmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method for operating a web-fed printing press according to the preamble of claim 1.

In einer Rollendruckmaschine wird mindestens eine Bedruckstoffbahn in mehreren Druckeinheiten bedruckt. Nach dem Bedrucken wird die oder jede Bedruckstoffbahn üblicherweise einem den Druckeinheiten nachgeordneten Wendeaufbau zugeführt, wobei im Bereich des Wendeaufbaus die oder jede Bedruckstoffbahn in Teilbahnen getrennt wird und/oder die oder jede Bedruckstoffbahn bzw. Teilbahnen wahlweise beziehungsweise optional gewendet werden. Dem Wendeaufbau und damit den Druckeinheiten ist ein Falzaufbau nachgeordnet, der mindestens einen Falztrichter zum Längsfalzen der oder jeder Bedruckstoffbahn bzw. der Teilbahnen aufweist. Dem Falzaufbau ist ein Falzapparat nachgeordnet, wobei im Bereich des Falzapparats durch Querschneiden von der oder jeder Bedruckstoffbahn bzw. von den Teilbahnen Exemplare abgetrennt werden. An den Exemplaren wird im Bereich des Falzapparats mindestens ein Längsfalz und/oder mindestens ein Querfalz ausgebildet.In a web-fed printing machine, at least one printing material web is printed in several printing units. After printing, the or each printing material web is usually fed to a printing unit downstream Wendeaufbau, in the area of the turning structure, the or each substrate web is divided into partial webs and / or the or each printing material or partial webs optionally or optionally turned. The folding structure and thus the printing units is followed by a folding structure having at least one former for longitudinal folding of the or each printing material or the partial webs. The folding structure is followed by a folder, being separated in the area of the folder by cross-cutting of the or each printing material or of the partial webs copies. At least one longitudinal fold and / or at least one transverse fold is formed on the copies in the area of the folding apparatus.

Die der Bearbeitung der oder jeder Bedruckstoffbahn bzw. der Teilbahnen dienende Baugruppen des Wendeaufbaus und/oder Falzaufbaus sind typischerweise an ein festes Format von Bedruckstoffbahnen bzw. Teilbahnen angepasst. Bislang ist es nicht möglich, sich beim Bedrucken ergebende Breitentoleranzen einer Bedruckstoffbahn auszugleichen.The processing of the or each printing material web or partial web serving assemblies of the turning structure and / or folding structure are typically adapted to a fixed format of printing material webs or partial webs. So far, it has not been possible to compensate for width tolerances of a printing substrate during printing.

Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde, ein neuartiges Verfahren zum Betreiben einer Rollendruckmaschine zu schaffen. Dieses Problem wird durch ein Verfahren zum Betreiben einer Rollendruckmaschine gemäß Anspruch 1 gelöst.On this basis, the present invention is based on the problem to provide a novel method for operating a web-fed printing press. This Problem is solved by a method for operating a web-fed printing machine according to claim 1.

Erfindungsgemäß werden zumindest der Bearbeitung der oder jeder Bedruckstoffbahn bzw. der Teilbahnen dienende Baugruppen des Falzaufbaus an ein sich beim Bedrucken ausbildendes Breitenwachstum der oder jeder Bedruckstoffbahn angepasst.According to the invention, at least the processing of the or each printing material web or the component webs serving subassemblies of the folding structure are adapted to a forming during printing width growth of the or each printing material.

Im Sinne der hier vorliegenden Erfindung wird erstmals vorgeschlagen, ein sich beim Bedrucken der oder jeder Bedruckstoffbahn ausbildendes Breitenwachstum der oder jeder Bedruckstoffbahn dadurch auszugleichen, dass zumindest der Bearbeitung der oder jeder Bedruckstoffbahn bzw. der Teilbahnen dienende Baugruppen des Falzaufbaus und gegebenenfalls Wendeaufbaus angepasst werden. Hierdurch kann ein durch Feuchtigkeitseintrag in die bedruckte Bedruckstoffbahn verursachtes Breitenwachstum der Bedruckstoffbahn kompensiert werden, wodurch die Qualität der auf der Rollendruckmaschine hergestellten Produkte verbessert wird.For the purposes of the present invention, it is proposed for the first time to compensate for a width growth of the or each printing material web which forms during printing of the or each printing material web, by adapting at least the processing of the or each printing material web or component webs of the folding structure and possibly turning structure. As a result, caused by moisture in the printed substrate web width growth of the substrate web can be compensated, whereby the quality of the products produced on the web printing machine is improved.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:

Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawings. Showing:
Fig. 1:
a schematic representation to illustrate the inventive method for operating a web press.

Die hier vorliegende Erfindung betrifft ein Verfahren zum Betreiben einer Rollendruckmaschine, wobei das erfindungsgemäße Verfahren nachfolgend unter Bezugnahme auf Fig. 1 für ein bevorzugtes Ausführungsbeispiel exemplarisch beschrieben wird.The present invention relates to a method for operating a web-fed printing press, the method according to the invention being described below with reference to FIG Fig. 1 for a preferred embodiment will be described by way of example.

So zeigt Fig. 1 stark schematisiert eine in einer Rollendruckmaschine bedruckte Bedruckstoffbahn 10, die in Richtung des Pfeils 11 durch eine Rollenrotationsdruckmaschine transportiert wird.So shows Fig. 1 strongly schematized printed in a web printing machine substrate sheet 10, which is transported in the direction of arrow 11 by a web-fed rotary printing press.

Im nachfolgenden soll davon ausgegangen werden, dass die noch nicht-bedruckte und demnach noch zu bedruckende Bedruckstoffbahn vor dem Bedrucken die Breite a und nach dem Bedrucken die Breite b aufweist, wobei die Breite b nach dem Bedrucken größer ist als die Breite a vor dem Bedrucken, und wobei dieses Breitenwachstum der Bedruckstoffbahn 10 infolge des Bedruckens einerseits vom verwendeten Bedruckstofftyp und andererseits von der Menge des zum Bedrucken verwendeten Feuchtmittels abhängig ist.In the following, it should be assumed that the not yet printed and therefore still to be printed substrate web before printing the width a and after printing the width b, wherein the width b after printing is greater than the width a before printing , and wherein this width growth of the printing material web 10 as a result of the printing on the one hand depends on the type of printing material used and on the other hand on the amount of dampening solution used for printing.

Die in Fig. 1 gezeigte Bedruckstoffbahn 10 ist eine 6-seitenbreite Bedruckstoffbahn, wobei die Seiten vor dem Bedrucken eine Breite a1, a2, a3, a4, a5 bzw. a6 und nach dem Bedrucken eine Breite b1, b2, b3, b4, b5 bzw. b6 aufweisen.In the Fig. 1 shown printing substrate 10 is a 6-page-wide substrate web, the pages before printing a width a1, a2, a3, a4, a5 and a6 and after printing a width b1, b2, b3, b4, b5 and b6 have.

Die bedruckte Bedruckstoffbahn 10 wird in Richtung des Pfeils 11 Falztrichtern 12 eines Falzaufbaus zugeführt, wobei die Bedruckstoffbahn 10 mit Hilfe von den Falztrichtern 12 vorgelagerten Schneideinrichtungen 13 durch Längsschneiden entweder in drei Teilbahnen oder in sechs Teilbahnen getrennt wird. Die Teilbahnen werden dann den Falztrichtern 12 zugeführt.The printed substrate web 10 is fed in the direction of the arrow 11 formers 12 a folding structure, the printing material 10 is separated by means of the former formers 12 upstream cutting devices 13 by longitudinal cutting either in three sub-webs or six sub-webs. The partial webs are then fed to the formers 12.

Bei aus der Praxis bekannten Rollendruckmaschinen sind die Falztrichter 12 des Falzaufbaus sowie die den Falztrichtern 12 vorgelagerten Schneideinrichtungen 13 auf die Breite a der Bedruckstoffbahn 10 vor dem Bedrucken derselben ausgelegt. Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, eine Rollendruckmaschine derart zu betreiben, dass zumindest der Bearbeitung der bedruckten Bedruckstoffbahn bzw. der Teilbahnen dienende Baugruppen des Falzaufbaus an ein sich beim Bedrucken ausbildendes Breitenwachstum der Bedruckstoffbahn 10 angepasst werden.In known from practice web presses, the formers 12 of the folder structure and the formers 12 upstream cutters 13 are designed to the width a of the printing substrate 10 before printing the same. For the purposes of the present invention, it is proposed to operate a web-fed printing press in such a way that at least the processing of the printed printing material web or of the sub-webs serving assemblies of the folding structure be adapted to a forming during printing width growth of the printing substrate 10.

Im gezeigten Ausführungsbeispiel werden hierzu zumindest die beiden äußeren Falztrichter 12 sowie die äußeren Schneideinrichtungen 13 quer zur Transportrichtung (Pfeil 11) der Bedruckstoffbahn 10 verlagert. Bei Druckmaschinen, die einen dem Falzaufbau vorgelagerten Wendeaufbau aufweisen, können dem Wendeaufbau zugeordnete Längsschneideeinrichtungen sowie Wendestangen an das Breitenwachstum der bedruckten Bedruckstoffbahn angepasst werden. Weiterhin können Zugwalzen bzw. sonstige Bahnleitwalzen des Falzaufbaus und gegebenenfalls des Wendeaufbaus an das Bahnbreitenwachstum der bedruckten Bedruckstoffbahn angepasst werden.In the illustrated embodiment, for this purpose, at least the two outer formers 12 and the outer cutters 13 transversely to the transport direction (arrow 11) of the printing material 10 moves. In printing presses, which have a folding structure upstream of the turning structure, the turning structure associated longitudinal cutting devices and turning bars can be adapted to the width growth of the printed substrate web. Furthermore, tension rollers or other web guide rollers of the folding structure and optionally of the turning structure can be adapted to the web width growth of the printed substrate web.

Da sich bedingt durch das Breitenwachstum der Bedruckstoffbahn 10 die mittige Lage derselben zur Druckmaschine typischerweise nicht verändert, können im gezeigten Ausführungsbeispiel der mittlere Falztrichter 12 sowie die mittlere Längsschneideeinrichtung 13, die jeweils auf die Mitte der Bedruckstoffbahn 10 ausgerichtet sind, in ihrer Position unverändert bleiben.Since due to the width growth of the printing material web 10, the central position of the same to the printing machine typically does not change, in the illustrated embodiment, the middle former 12 and the central longitudinal cutting device 13, which are each aligned with the center of the printing substrate 10, remain unchanged in their position.

Wie bereits ausgeführt, ist das Breitenwachstum der Bedruckstoffbahn vom Bedruckstofftyp sowie von der Menge des zum Drucken verwendeten Feuchtmittels abhängig. Die Verlagerung der jeweiligen Falztrichter 12 sowie Längsschneideeinrichtungen 13 zur Kompensation des Breitenwachstums der bedruckten Bedruckstoffbahn 10 erfolgt vorzugsweise auf Basis vorab empirisch ermittelter, vom Bedruckstofftyp und der Menge des Feuchtmittels abhängiger Werte.As already stated, the width growth of the printing substrate is dependent on the printing substrate type and on the amount of dampening solution used for printing. The displacement of the respective formers 12 and longitudinal cutters 13 to compensate for the width of the printed substrate web 10 is preferably carried out on the basis of pre-empirically determined, dependent on the type of printing material and the amount of dampening solution values.

Bei für den Zeitungsdruck verwendeten Papiertypen beträgt das Breitenwachstum der bedruckten Bedruckstoffbahn zwischen 1 Promille und 3 Promille, woraus folgt, dass auch die Falztrichter 12 sowie Längsschneideeinrichtungen 13 in dieser Größenordnung verlagert werden, um das Breitenwachstum auszugleichen.For paper types used for newspaper printing, the width growth of the printed substrate web is between 1 per mille and 3 per mille, which implies that also the former 12 and longitudinal cutters 13 are displaced in this order of magnitude to compensate for the broad growth.
