Description
Die Erfindung betrifft eine Einrichtung zum Behandeln einer Papierbahn oder eines Papierbogens gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for treatment a paper web or a paper sheet 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 erfindungsgemäß 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 have to be assigned to the pair of calender rolls 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 method can be used advantageously in dry offset printing processes in which a cleaning effect of the printing plate by dampening systems is eliminated. Furthermore, according to the invention, a paper web tension control device is 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 is closer 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
In this
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, z. 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
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
Anstelle von Papierbahnen 3 ist die Anordnung des
Kalanderpaares auch auf Papierbogen, z. B. in
Bogendruckmaschinen verwendbar.Instead of
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
