Description

Die Erfindung betrifft eine Einrichtung zum Behandeln einer Papierbahn gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for treatment a paper web according to the preamble of claim 1.

Durch die DE 21 61 322 C3 ist eine Vorrichtung zum Behandeln von Papierbahnen vor dem Druck bekannt, bei welcher die Papierbahn mittels eines Streckwalzenpaares einem Vorwalkprozeß ausgesetzt wird, um die Papierbahn während des Bedruckens stabil zu halten.DE 21 61 322 C3 is a device for Treat paper webs before printing, known at which the paper web by means of a pair of stretching rollers is subjected to a pre-walking process around the paper web to keep stable during printing.

Weiterhin haben die Streckwalzen eine zumindest geringfügig andere Umfangsgeschwindigkeit gegenüber den Zylindern der nachfolgenden Druckwerke. Dadurch sollen etwaiger Papierstaub oder lose mit der Papierbahn verbundene Partikel schon vor dem Einlauf in das erste Druckwerk entfernt werden. An jede Streckwalze ist ein Feuchtmittelwerk anstellbar.Furthermore, the stretching rollers have at least one slightly different peripheral speed compared to the Cylinders of the following printing units. This is supposed to any paper dust or loose with the paper web connected particles even before entering the first Printing unit to be removed. There is a on each stretching roller Fountain solution adjustable.

Die DE 196 17 601 A1 beschreibt ein Verfahren zum Bedrucken und Veredeln von Bahnen, wobei die laufende Bahn satiniert und anschließend ohne Zwischenaufwicklung bedruckt wird.DE 196 17 601 A1 describes a method for Printing and finishing of webs, the current one Satin web and then without intermediate rewind is printed.

Die DE-PS 245 182 zeigt eine Papierbahn, die zwischen Lackieren und Bedrucken satiniert wird. DE-PS 245 182 shows a paper web between Varnishing and printing is satined.

Die US 21 47 421 offenbart Kalanderwalzen, wobei eine der Kalanderwalzen von einem drehzahlgesteuerten Elektromotor angetrieben wird.The US 21 47 421 discloses calender rolls, one of the calender rolls by a speed-controlled Electric motor is driven.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Behandeln einer Papierbahn oder Papierbogen vor dem Bedrucken zu schaffen.The invention has for its object a Device for treating a paper web or Create sheets of paper before printing.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. According to the invention, this object is achieved by the features of claim 1 solved.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß dem Kalanderwalzenpaar keine zusätzlichen maschinellen Hilfsmittel oder Feuchtwasser zugeordnet werden muß, um den Papierstaub bzw. solche der Papierbahn anhaftenden Partikel unwirksam zu machen. Der Bedruckstoff erhält durch das Verdichten eine bessere Qualität, so daß ein Bedruckstoff minderer Qualität verwendet werden kann. Das Verfahren ist vorteilhaft bei
Trockenoffset-Druckverfahren anwendbar, bei welchen eine reinigende Wirkung der Druckplatte durch Feuchtwerke entfällt. Weiterhin ist vorteilhafterweise zwischen dem Kalanderwalzenpaar und dem ersten Druckwerk eine Papierbahnspannungs-Regeleinrichtung angeordnet, um durch den Kalanderprozeß auftretende Papierbahnspannungsschwankungen ausgleichen zu können.The advantages that can be achieved with the invention are, in particular, that no additional mechanical aids or dampening water has to be assigned to the pair of calender rollers in order to render the paper dust or particles adhering to the paper web ineffective. The printing material gets a better quality from the compression, so that a printing material of inferior quality can be used. The procedure is advantageous for
Dry offset printing process can be used, in which a cleaning effect of the printing plate by dampening systems is not applicable. Furthermore, a paper web tension control device is advantageously arranged between the pair of calender rollers and the first printing unit, in order to be able to compensate for paper web tension fluctuations that occur due to the calender process.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die einzige Figur zeigt eine schematische Darstellung des Papierbahnverlaufes bis zum ersten Druckwerk einschließlich der erfindungsgemäßen Einrichtung.An embodiment of the invention is in the Drawing shown and will be described in more detail below described. The only figure shows a schematic Representation of the paper web course up to the first Printing unit including those according to the invention Facility.

Von einer auf einem Rollenwechsler 1 befindlichen Papierbahnvorratsrolle 2 wird eine Papierbahn 3 abgezogen und über eine Umlenkwalze 4 einem aus zwei Kalanderwalzen 6; 7 bestehendem Kalanderwalzenpaar 8 zugeführt. Nachfolgend läuft die Papierbahn 3 über eine Papierbahnspannungs-Regeleinrichtung 9 in ein Druckwerk 11 einer Rollenrotationsdruckmaschine ein. Das Druckwerk 11 steht mit nicht dargestellten Farbwerken, z. B. für sogenannten wasserlosen Offsetdruck (Trockenoffset) in Verbindung.
In diesem Druckwerk 11 werden beispielsweise "wasserlose" Druckformen, z. B. Flachdruckformen oder Flachdruckplatten oder Flachdruckfolien verwendet, so daß keine Feuchtwerke notwendig sind. Damit entfällt aber auch die "Reinigungswirkung" der Feuchtwerke.A paper web 3 is drawn off from a paper web supply roll 2 located on a reel changer 1 and one of two calender rollers 6; 7 existing calender roller pair 8 supplied. The paper web 3 then runs via a paper web tension control device 9 into a printing unit 11 of a web-fed rotary printing press. The printing unit 11 is with inking units, not shown, for. B. for so-called waterless offset printing (dry offset) in connection.
In this printing unit 11, for example, "waterless" printing forms, for. B. planographic printing plates or planographic printing plates or planographic printing foils are used, so that no dampening units are necessary. This also eliminates the "cleaning effect" of the dampening units.

Die Kalanderwalzen 6; 7 können jeweils einen elastischen überzug, z. B. aus Gummi oder einen harten überzug, z. B. aus Metall (Chrom) aufweisen.The calender rolls 6; 7 can each have an elastic coating, e.g. B. made of rubber or a hard coating, e.g. B. made of metal (chrome).

Nach einer anderen Ausführungsvariante ist es möglich, daß eine erste Kalanderwalze 6 oder 7 einen elastischen überzug und eine zweite Kalanderwalze 7 oder 6 einen harten überzug aufweist.According to another variant, it is possible to that a first calender roll 6 or 7 has an elastic coating and a second calender roll 7 or 6 one hard coating.

Das Kalanderwalzenpaar 8 kann einen gemeinsamen Antrieb aufweisen oder jede Kalanderwalze 6; 7 kann mit einem Einzelantrieb, z. B. einem Elektromotor versehen sein. Auch ist es möglich nur eine Kalanderwalze 6 oder 7 anzutreiben. Der Antrieb kann beispielsweise mittels eines winkellagegeregelten Elektromotors erfolgen.The pair of calender rolls 8 can have a common drive have or each calender roll 6; 7 can with one Single drive, e.g. B. an electric motor. It is also possible to have only one calender roll 6 or 7 to drive. The drive can, for example, by means of of an angular position controlled electric motor.

Der Antrieb ist also mechanisch unabhängig von anderen Aggregaten, z. B. Druckwerken der Druckmaschine, d. h. nicht antriebstechnisch gekoppelt.The drive is therefore mechanically independent of others Aggregates, e.g. B. printing units of the printing press, d. H. not coupled in terms of drive technology.

Infolge der Anordnung eines Kalanderwalzenpaares 8 vor dem Druckwerk 11 werden der Papierbahn 3 anhaftender Papierstaub oder andere Partikel in die Oberfläche der Papierbahn 3 eingebracht, d. h. eingewalzt. Ein Entfernen dieser Partikel entfällt und somit zusätzliche Vorrichtungskosten. Die Qualität der Papierbahn wird verbessert.Due to the arrangement of a pair of calender rolls 8 before the printing unit 11, the paper web 3 become more adherent Paper dust or other particles in the surface of the Paper web 3 introduced, d. H. rolled in. On Removal of these particles is eliminated and therefore additional Device cost. The quality of the paper web will improved.

Anstelle von Papierbahnen 3 ist die Anordnung des Kalanderpaares auch auf Papierbogen, z. B. in Bogendruckmaschinen verwendbar.Instead of paper webs 3, the arrangement of the Pair of calenders also on sheets of paper, e.g. B. in Sheet printing machines can be used.

Durch die Anordnung der Papierbahnspannungs-Regeleinrichtung 9 zwischen dem Kalanderwalzenpaar 8 und dem Druckwerk 11 wird dem Druckwerk 11 eine Papierbahn 3 stets gleichbleibender Bahnspannung zugeführt. By arranging the Paper web tension control device 9 between the Calender roller pair 8 and the printing unit 11 is the Printing unit 11 a paper web 3 always constant Web tension fed.
