Definitions
- the invention relates to a method for finishing and printing webs, in particular paper, and to a printing press for printing finished webs for carrying out the method.
- the base paper leaving the paper machine still needs to be refined so that the different demands placed on a paper to be printed are taken into account.
- the finishing processes primarily include painting and satinizing the paper.
- coating a coating color consisting of pigments and binders is applied to the base paper using a coating system on one or both sides. By painting you get a closed and smooth, easily printable paper surface.
- calenders which have at least one nip, but preferably a plurality of nips, which are delimited by hard and preferably heatable cast iron or steel rollers or by soft rollers which are provided with an elastic covering. In these nips the web is subjected to a pressure treatment and in most cases also to a temperature treatment which leads to the desired smoothing.
- Such calenders are widely known, for example from DE-U-295 04 034.3.
- Coating lines and calenders have so far been installed in paper mills and have been added to a paper machine in-line or off-line.
- the finished web which has a width corresponding to the paper machine, is formed into a roll in a winding device.
- it is very difficult to produce a uniform winding in particular because the web tends to slip laterally due to its high surface smoothness on the air cushion present during winding.
- the rolls are usually still cut in the paper mill to narrower widths, which corresponds to the working width of the printing press.
- roll slitting machines which divide the wide web coming from a winding into individual partial webs with the help of slitters and each form a roll with a smaller width in a winding station. Even with this rewinding process there is a tendency that the webs shift laterally due to their smooth surface.
- the invention has for its object to improve the provision of refined paper for printing.
- This object is achieved in that the running web is refined and then printed without intermediate rewinding.
- Another advantage is the improved print quality. So far, it has been inevitable that the web material will lose smoothness during the long storage and transportation times before printing begins. This effect is due to the fact that the leveled fibers relax on the web surface and straighten again. According to the invention, however, there is only a very short period of time between the finishing and the printing of the web. In it, a re-erection of the surface fibers is practically impossible. This makes it possible to adjust the surface smoothness in this way or to regulate that it is optimally adapted to the color application when printing.
- the web still to be finished is preferably cut to the width required for printing, formed into a roll and pulled off this roll for finishing and printing.
- a wide web is divided into several sub-webs, which have not yet been finished. They are therefore easy to wrap.
- less complex packaging is sufficient because the web has not yet reached its final finishing stage and because the moisture content can still be influenced when brushing or satinizing.
- the finished web is advantageously tempered before printing. This is one way of achieving a particularly good adaptation of the web to the printing process.
- the finishing can be done in particular by calendering, by brushing or by brushing and subsequent calendering. It is worth striving to do all of the finishing in the print shop. Significant advantages of the invention are achieved, however, if only the final finishing treatment is carried out in one pass with the printing, ie part of the finishing is already carried out in the paper mill.
- one solution of the problem in constructive terms is that a device for refining the paper web, the throughput speed of which is adapted to that of the printing press, is connected upstream of the input of the printing press.
- the upstream finishing device can be a coating system and / or a calendering calender. In both cases, the surface of the paper web is smoothed, which improves printability.
- the finishing device works comparatively slowly.
- the coating color can be applied carefully with less effort.
- a calender there are longer dwell times of the web in the nip. This leads to higher smoothness values.
- such a slow-running calender compared to the calenders that are customary in paper mills, is easier to manufacture, operate and more cost-effective.
- the working width of the finishing device is the same or slightly larger than that of the printing press. Since the finishing device is permanently assigned to the printing press, its working width can also be adapted to that of the printing press. Because of this smaller width, in addition to the lower speed, compared to the coating lines and calenders in the paper mill that have been customary up to now, the manufacturing costs are extremely low.
- a temperature control device influencing the web temperature is arranged between the output of the finishing device and the input of the printing press.
- an unwinding station 1 contains a roll 2 of a web 3 of unsatinated paper.
- the web 3 passes through a calender 4, the exit 5 of which leaves it as a satin-finished, that is, finished web 3 '.
- a tempering roller 6 which defines the web temperature, enters the input 7 of a printing press 8 and, in the usual way, reaches a folder 9 at the end of the printing press 8.
- the calender 4 consists of hard rolls 10, which consist of steel or chilled cast iron and are heated, and of soft rolls 11, which bear an elastic cover 12.
- the rollers 10 and 11 are pressed against each other in their direction of action by means not shown, so that the web 3 in the nips 13 is influenced by pressure and temperature and is thereby smoothed.
- the printing press 8 has four printing units 14 to 17 for straight printing and four printing units 18 to 21 for reverse printing. It can therefore be an 8-color rotogravure rotary press.
- the individual printing units 14 to 21 have gravure cylinders 23 immersed in ink tanks 22 in the usual manner.
- the web 3 ' is guided in each printing unit between this gravure cylinder 23 and an adjacent rubber press 24 and then with the aid guided by tensioning means 25 via at least one drying cylinder 26.
- the printing press 8 has a common drive shaft 27 which drives the intaglio cylinders 23 via corresponding gears 28 and 29.
- FIG. 2 shows a coating system 30 with an upstream processing station 31 and a downstream printing machine 8, the structure of which corresponds to that of FIG. 1 and which is closed by a folder 9.
- the path 32 passes through a path determined by guide rollers 33. Coating paint is applied to a coating sump 33 and the excess is wiped off by a doctor blade 35. This is followed by a first drying in an infrared heating device 36 and a second drying in a hot air drying device 37.
- the coated web 32 'partially wraps around the heating roller 6 and then enters the printing press 8.
- the paper web is therefore removed from a roll mounted on the unwinding station 31, passed through a finishing device, namely the coating system, and introduced directly into the printing press 8.
- a paper machine 38 is illustrated, at the output of which a roll cutting and winding device 39 is provided.
- the raw paper web which is the width of the paper machine, is cut into narrower webs; these are then wound up into individual rolls. These rolls of smaller width are made ready for dispatch in a packaging station 40.
- a dashed Line 41 schematically represents the boundary between a paper mill 42 and a print shop 43, which can be at any distance from one another.
- the web is removed from a processing station 31, passed over a coating system 30 and a calender 31 and finally taken over by the printing press 8 without any intermediate rewinding.
- the web 32 is subject to the action of a coating machine 30 and then to the action of a calender 4.
- calender 4 instead of the illustrated calender 4 with seven nips, it is also possible to provide a calender with a stack of a larger number of rolls or a calender with a smaller number of rolls, for example a soft calender with one nip or two successive nips.

Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Veredeln und Bedrucken von Bahnen, insbesondere aus Papier, und auf eine Druckmaschine zum Bedrucken von veredelten Bahnen zur Durchführung des Verfahrens.The invention relates to a method for finishing and printing webs, in particular paper, and to a printing press for printing finished webs for carrying out the method.
In vielen Fällen bedarf das die Papiermaschine verlassende Rohpapier noch einer Veredelung, damit den unterschiedlichen Ansprüchen, die an ein zu bedruckendes Papier gestellt werden, Rechnung getragen wird. Zu den Veredelungsverfahren gehören in erster Linie das Streichen und das Satinieren des Papiers.In many cases, the base paper leaving the paper machine still needs to be refined so that the different demands placed on a paper to be printed are taken into account. The finishing processes primarily include painting and satinizing the paper.
Beim "Streichen" wird mit Hilfe einer Streichanlage einseitig oder beidseitig eine Streichfarbe, bestehend aus Pigmenten und Bindemitteln, auf das Rohpapier aufgetragen. Durch das Streichen erhält man eine geschlossene und glatte, gut bedruckbare Papieroberfläche.With "coating", a coating color consisting of pigments and binders is applied to the base paper using a coating system on one or both sides. By painting you get a closed and smooth, easily printable paper surface.
Unter "Satinieren" von Papier, Pappe o.dgl. versteht man die Erzeugung von Glätte oder Glanz an der Oberfläche der Bahn. Hiervon hängt in hohem Maße der Farbauftrag beim Bedrucken ab. Zum Satinieren werden in erster Linie Kalander verwendet, die mindestens einen Walzenspalt, vorzugsweise aber mehrere Walzenspalte aufweisen, die durch harte und vorzugsweise beheizbare Walzen aus Hartguß oder Stahl bzw. durch weiche Walzen, die mit einem elastischen Belag versehen sind, begrenzt werden. In diesen Walzenspalten wird die Bahn einer Druckbehandlung und in den meisten Fällen auch einer Temperaturbehandlung unterworfen, die zu der gewünschten Glättung führt. Solche Kalander sind vielfach bekannt, beispielsweise aus DE-U-295 04 034.3.Under "satinizing" of paper, cardboard or the like. one understands the production of smoothness or gloss on the surface of the web. The color application during printing depends to a large extent on this. For calendering, primarily calenders are used which have at least one nip, but preferably a plurality of nips, which are delimited by hard and preferably heatable cast iron or steel rollers or by soft rollers which are provided with an elastic covering. In these nips the web is subjected to a pressure treatment and in most cases also to a temperature treatment which leads to the desired smoothing. Such calenders are widely known, for example from DE-U-295 04 034.3.
Streichanlagen und Kalander sind bisher in Papierfabriken aufgestellt und im Arbeitsablauf einer Papiermaschine in-line oder off-line nachgeschaltet worden. Die veredelte Bahn, die eine der Papiermaschine entsprechende Breite besitzt, wird in einer Aufwickelvorrichtung zu einer Rolle geformt. Hierbei macht es erhebliche Schwierigkeiten, einen gleichmäßigen Wickel zu erzeugen, insbesondere weil die Bahn durch ihre hohe Oberflächenglätte auf dem beim Wickeln vorhandenen Luftpolster dazu neigt, seitlich zu verrutschen.Coating lines and calenders have so far been installed in paper mills and have been added to a paper machine in-line or off-line. The finished web, which has a width corresponding to the paper machine, is formed into a roll in a winding device. Here it is very difficult to produce a uniform winding, in particular because the web tends to slip laterally due to its high surface smoothness on the air cushion present during winding.
Zur Weiterverarbeitung der Papierbahn in einer Druckerei werden die Rollen üblicherweise noch in der Papierfabrik auf schmalere Breiten, die der Arbeitsbreite der Druckmaschine entspricht, geschnitten. Dies geschieht mit sogenannten Rollenschneidmaschinen, die die breite, von einer Abwicklung kommende Bahn mit Hilfe von Längsschneidern in einzelne Teilbahnen aufteilt und diese je für sich in einer Wickelstation zu einer Rolle mit geringerer Breite formt. Auch bei diesem erneuten Aufwickelvorgang besteht die Neigung, daß die Bahnen sich aufgrund ihrer glatten Oberfläche seitlich verschieben.For further processing of the paper web in a printing house, the rolls are usually still cut in the paper mill to narrower widths, which corresponds to the working width of the printing press. This is done with so-called roll slitting machines, which divide the wide web coming from a winding into individual partial webs with the help of slitters and each form a roll with a smaller width in a winding station. Even with this rewinding process there is a tendency that the webs shift laterally due to their smooth surface.
Die einzelnen Rollen aus veredelter Papierbahn müssen anschließend einzeln verpackt werden, damit sie geschützt zu einer Druckerei weiter transportiert werden können und dabei die Papierfeuchtigkeit erhalten bleibt. Diese Verpackung ist recht aufwendig.The individual rolls of refined paper web must then be individually packaged so that they can be safely transported to a print shop and the paper moisture is retained. This packaging is quite complex.
Der Erfindung liegt die Aufgabe zugrunde, die Bereitstellung von veredeltem Papier für das Bedrucken zu verbessern.The invention has for its object to improve the provision of refined paper for printing.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die laufende Bahn veredelt und anschließend ohne Zwischenaufwicklung bedruckt wird.This object is achieved in that the running web is refined and then printed without intermediate rewinding.
Bei diesem Vorgehen wird das Aufwickeln von veredeltem Papier zu einer Rolle vollständig vermieden. Die laufende Bahn tritt kurz nach Abschluß der Veredelungs-Behandlung in den Druckbereich ein. Auch die einzelnen Aufwickelvorgänge in der Papierfabrik werden ganz wesentlich erleichtert. Denn nunmehr braucht lediglich das Rohpapier zur Rolle geformt zu werden, das sich wegen der rauhen Oberfläche und des größeren Volumens wesentlich besser wickeln läßt als veredeltes und daher glattes Papier.This completely avoids winding finished paper into a roll. The running web enters the printing area shortly after finishing treatment. The individual winding operations in the paper mill are also made considerably easier. Because now only the raw paper needs to be formed into a roll, which is much easier to wrap than refined and therefore smooth paper due to the rough surface and the larger volume.
Ein weiterer Vorteil liegt in der verbesserten Druckqualität. Bisher war es unvermeidbar, daß das Bahnmaterial während der langen Lagerungs- und Transportzeiten an Glätte einbüßt, bevor es zum Druckvorgang kommt. Dieser Effekt ist darauf zurückzuführen, daß sich die eingeebneten Fasern an der Bahnoberfläche entspannen und erneut aufrichten. Erfindungsgemäß liegt aber zwischen dem Veredeln und dem Bedrucken der Bahn nur ein sehr kurzer Zeitraum. In ihm ist ein Wiederaufrichten der Oberflächenfasern praktisch ausgeschlossen. Dies macht es möglich, die Oberflächenglätte so einzustellen oder zu regeln, daß sie dem Farbauftrag beim Bedrucken optimal angepaßt ist.Another advantage is the improved print quality. So far, it has been inevitable that the web material will lose smoothness during the long storage and transportation times before printing begins. This effect is due to the fact that the leveled fibers relax on the web surface and straighten again. According to the invention, however, there is only a very short period of time between the finishing and the printing of the web. In it, a re-erection of the surface fibers is practically impossible. This makes it possible to adjust the surface smoothness in this way or to regulate that it is optimally adapted to the color application when printing.
Vorzugsweise wird die noch zu veredelnde Bahn auf die zum Bedrucken erforderliche Breite geschnitten, zu einer Rolle geformt sowie zum Veredeln und Bedrucken von dieser Rolle abgezogen. In der Papierfabrik wird daher wie üblich eine breite Bahn in mehrere Teilbahnen aufgeteilt, die aber noch nicht veredelt sind. Sie lassen sich daher leicht wickeln. Außerdem genügt eine weniger aufwendige Verpackung, weil die Bahn noch nicht ihre letzte Veredelungsstufe erreicht hat und weil auf den Feuchtigkeitsgehalt noch beim Streichen oder Satinieren Einfluß genommen werden kann.The web still to be finished is preferably cut to the width required for printing, formed into a roll and pulled off this roll for finishing and printing. In the paper mill, as usual, a wide web is divided into several sub-webs, which have not yet been finished. They are therefore easy to wrap. In addition, less complex packaging is sufficient because the web has not yet reached its final finishing stage and because the moisture content can still be influenced when brushing or satinizing.
Mit Vorteil wird die veredelte Bahn vor dem Bedrucken temperiert. Dies ist eine Möglichkeit, um eine besonders gute Anpassung der Bahn an den Druckvorgang zu erreichen.The finished web is advantageously tempered before printing. This is one way of achieving a particularly good adaptation of the web to the printing process.
Das Veredeln kann insbesondere durch Satinieren, durch Streichen oder durch Streichen und nachfolgendes Satinieren erfolgen. Hierbei ist es zwar erstrebenswert, die gesamte Veredelung in der Druckerei vorzunehmen. Wesentliche Vorteile der Erfindung werden aber schon erreicht, wenn lediglich die abschließende Veredelungs-Behandlung in einem Durchlauf mit dem Bedrucken erfolgt, ein Teil der Veredelung also bereits in der Papierfabrik vorgenommen wird.The finishing can be done in particular by calendering, by brushing or by brushing and subsequent calendering. It is worth striving to do all of the finishing in the print shop. Significant advantages of the invention are achieved, however, if only the final finishing treatment is carried out in one pass with the printing, ie part of the finishing is already carried out in the paper mill.
Eine Lösung der gestellten Aufgabe besteht erfindungsgemäß in konstruktiver Hinsicht darin, daß dem Eingang der Druckmaschine eine Vorrichtung zum Veredeln der Papierbahn, deren Durchlaufgeschwindigkeit derjenigen der Druckmaschine angepaßt ist, vorgeschaltet ist.According to the invention, one solution of the problem in constructive terms is that a device for refining the paper web, the throughput speed of which is adapted to that of the printing press, is connected upstream of the input of the printing press.
Insbesondere kann die vorgeschaltete Veredelungsvorrichtung eine Streichanlage und/oder ein Satinierkalander sein. In beiden Fällen wird die Oberfläche der Papierbahn geglättet, was die Bedruckbarkeit verbessert.In particular, the upstream finishing device can be a coating system and / or a calendering calender. In both cases, the surface of the paper web is smoothed, which improves printability.
In Folge der Anpassung an die Druckmaschinen-Durchlaufgeschwindigkeit arbeitet die Veredelungsvorrichtung vergleichsweise langsam. Bei einer Streichanlage läßt sich die Streichfarbe mit geringerem Aufwand sorgfältig aufbringen. Bei einem Kalander ergeben sich längere Verweilzeiten der Bahn im Walzenspalt. Dies führt zu höheren Glättewerten. Außerdem ist ein solcher im Vergleich zu den in Papierfabriken üblichen Kalandern langsam laufender Kalander einfacher herzustellen, zu bedienen und kostengünstiger.As a result of the adaptation to the printing machine throughput speed, the finishing device works comparatively slowly. With a coating system, the coating color can be applied carefully with less effort. With a calender, there are longer dwell times of the web in the nip. This leads to higher smoothness values. In addition, such a slow-running calender, compared to the calenders that are customary in paper mills, is easier to manufacture, operate and more cost-effective.
Vorteilhaft ist es auch, daß die Arbeitsbreite der Veredelungsvorrichtung gleich oder geringfügig größer als diejenige der Druckmaschine ist. Da die Veredelungsvorrichtung der Druckmaschine fest zugeordnet ist, kann auch ihre Arbeitsbreite derjenigen der Druckmaschine angepaßt sein. Wegen dieser geringeren Breite, zusätzlich zu der geringeren Geschwindigkeit, im Vergleich zu den bisher üblichen Streichanlagen und Kalandern in der Papierfabrik, ergeben sich ausgesprochen niedrige Herstellungskosten.It is also advantageous that the working width of the finishing device is the same or slightly larger than that of the printing press. Since the finishing device is permanently assigned to the printing press, its working width can also be adapted to that of the printing press. Because of this smaller width, in addition to the lower speed, compared to the coating lines and calenders in the paper mill that have been customary up to now, the manufacturing costs are extremely low.
In weiterer Ausgestaltung ist dafür gesorgt, daß zwischen dem Ausgang der Veredelungsvorrichtung und dem Eingang der Druckmaschine eine die Bahntemperatur beeinflussende Temperiervorrichtung angeordnet ist.In a further embodiment, it is ensured that a temperature control device influencing the web temperature is arranged between the output of the finishing device and the input of the printing press.

Gemäß Fig. 1 enthält eine Abwickelungsstation 1 eine Rolle 2 aus einer Bahn 3 unsatinierten Papiers. Die Bahn 3 durchläuft einen Kalander 4, dessen Ausgang 5 sie als satinierte, also veredelte Bahn 3' verläßt. Sie umschlingt mit einem Winkel von mehr als 180° eine Temperierwalze 6, welche die Bahntemperatur festlegt, tritt in den Eingang 7 einer Druckmaschine 8 ein und gelangt in üblicher Weise zu einem Falzapparat 9 am Ende der Druckmaschine 8.1, an unwinding station 1 contains a
Der Kalander 4 besteht aus harten Walzen 10, die aus Stahl oder Hartguß bestehen und beheizt sind, sowie aus weichen Walzen 11, die einen elastischen Bezug 12 tragen. Die Walzen 10 und 11 werden durch nicht-veranschaulichte Mittel in ihrer Wirkrichtung gegeneinander gepreßt, so daß die Bahn 3 in den Walzenspalten 13 durch Druck- und Temperatur beeinflußt und dadurch geglättet wird.The calender 4 consists of
Die Druckmaschine 8 besitzt vier Druckwerke 14 bis 17 für den Schöndruck und vier Druckwerke 18 bis 21 für den Widerdruck. Es kann sich daher um eine 8-Farben-Tiefdruck-Rollenrotationsmaschine handeln. Die einzelnen Druckwerke 14 bis 21 weisen in der üblichen Weise in Farbwannen 22 eingetauchte Tiefdruckzylinder 23 auf. Die Bahn 3' wird in jedem Druckwerk zwischen diesem Tiefdruckzylinder 23 und einem anliegenden Gummipresseur 24 hindurchgeführt und anschließend unter Zuhilfenahme von Spannmitteln 25 über wenigstens einen Trokkenzylinder 26 geführt. Die Druckmaschine 8 besitzt eine gemeinsame Antriebswelle 27, welche die Tiefdruckzylinder 23 über entsprechende Getriebe 28 bzw. 29 antreibt.The
Durch Regelung des Drucks im Walzenspalt und/oder der Temperatur der harten Walzen 10 kann eine Anpassung des Glätte- oder Glanzwertes an die für einen optimalen Druck in der Druckmaschine 8 zu schaffenden Voraussetzungen erzeugt werden.By regulating the pressure in the nip and / or the temperature of the
Fig. 2 zeigt eine Streichanlage 30 mit vorgeschalteter Abwicklungsstation 31 und nachgeschalteter Druckmaschine 8, deren Aufbau demjenigen der Fig. 1 entspricht und die von einem Falzapparat 9 abgeschlossen wird. Die Bahn 32 durchläuft eine von Leitwalzen 33 bestimmte Bahn. An einem Streichsumpf 33 wird Streichfarbe aufgetragen und der Überschuß durch eine Rakel 35 abgestreift. Anschließend erfolgt eine erste Trocknung in einer Infrarot-Heizvorrichtung 36 und eine zweite Trocknung in einer Heißluft-Trocknungsvorrichtung 37. Die gestrichene Bahn 32' umschlingt teilweise die Heizwalze 6 und tritt dann die Druckmaschine 8 ein. Auch hier wird daher die Papierbahn von einer an der Abwikkelstation 31 gelagerten Rolle abgenommen, durch eine Veredelungsvorrichtung, nämlich die Streichanlage, geführt und direkt in die Druckmaschine 8 eingeleitet.FIG. 2 shows a
Bei dem Blockschaltbild der Fig. 3 ist eine Papiermaschine 38 veranschaulicht, an deren Ausgang eine Rollenschneid- und -Wickelvorrichtung 39 vorgesehen ist. In ihr wird die Rohpapierbahn, welche die Breite der Papiermaschine hat, in schmalere Bahnen geschnitten; diese werden dann in einzelne Rollen aufgewickelt. Diese Rollen geringerer Breite werden in einer Verpakkungsstation 40 versandfertig gemacht. Eine gestrichelte Linie 41 stellt schematisch die Grenze zwischen einer Papierfabrik 42 und einer Druckerei 43 dar, die eine beliebige Entfernung voneinander haben können. In der Druckerei 43 wird die Bahn von einer Abwicklungsstation 31 abgenommen, über eine Streichanlage 30 und einen Kalander 31 geführt und schließlich ohne jegliche Zwischenaufwicklung von der Druckmaschine 8 übernommen. In diesem Fall unterliegt die Bahn 32 der Wirkung einer Streichmaschine 30 und danach der Wirkung eines Kalanders 4.In the block diagram of FIG. 3, a
Anstelle der veranschaulichten 8-Farben-Tiefdruck-Rollenrotationsmaschine können auch andere Druckmaschinen verwendet werden, beispielsweise solche, die mit Hochdruck oder Flachdruck arbeiten.Instead of the illustrated 8-color rotogravure web-fed rotary press, other printing presses can also be used, for example those that work with high-pressure or planographic printing.
Statt des veranschaulichten Kalanders 4 mit sieben Walzenspalten kann auch ein Kalander mit einem Stapel aus einer größeren Walzenanzahl oder ein Kalander mit einer geringeren Walzenanzahl, beispielsweise ein Softkalander mit einem Walzenspalt oder zwei hintereinander geschalteten Walzenspalten vorgesehen werden.Instead of the illustrated calender 4 with seven nips, it is also possible to provide a calender with a stack of a larger number of rolls or a calender with a smaller number of rolls, for example a soft calender with one nip or two successive nips.
