Abstract

To prepare the surface of a paper or cardboard web for calendering or printing, it is treated with an atmospheric plasma. The surface of the paper or cardboard web is treated by a corona discharge, shortly before it enters the calender or printing press.

Description

Es ist seit langem bekannt, daß beim Kalandrieren von Papier oder Karton die Oberflächentemperatur und die Ober­ flächenfeuchtigkeit und auch die Arbeitsgeschwindigkeit genau einzuhalten sind, wenn optimale Ergebnisse hinsicht­ lich Glanz und Glätte bei möglichster Schonung des Volu­ mens der inneren Partien des Papiers bzw. des Kartons erzielt werden sollen. Nur beispielsweise ist hierzu auf die DE 36 00 033 A1, die US-Psen 3 124 480 und 4 749 445 und die EP 245 250 B2 zu verweisen.It has long been known that when calendering Paper or cardboard the surface temperature and the surface surface moisture and also the working speed are to be followed exactly if optimal results are concerned shine and smoothness with the greatest possible protection of the volume the inner parts of the paper or cardboard should be achieved. Just for example is on this DE 36 00 033 A1, US Psen 3 124 480 and 4 749 445 and to refer to EP 245 250 B2.

Die Steigerung der Temperatur der Kalanderwalzen dient im Verein mit einer gewissen Feuchte, die sogar vor dem Kalandrieren eigens aufgebracht werden kann, der Her­ beiführung einer gewissen Plastifizierung der oberflächen­ nahen Fasern des Papiers oder Kartons, um dessen Einebnung und Glätte zu fördern. Bis die hohe Temperatur der Kalan­ derwalzen erreicht ist, haben das Papier oder der Karton den Walzspalt schon wieder verlassen. Zur Einstellung der Feuchtigkeit der Bahn vor und nach dem Kalandrieren seien als Beispiele die DE-PS 8 64 654, die DE-AS 10 54 321 und die EP 169 988 genannt.The increase in the temperature of the calender rolls serves in association with a certain level of moisture, even before the calendering can be applied specifically, the Her a certain plasticization of the surfaces nearby fibers of the paper or cardboard to level it and promote smoothness. Until the high temperature of the Kalan The rollers or paper have been reached leave the nip again. To set the Moisture of the web before and after calendering  as examples DE-PS 8 64 654, DE-AS 10 54 321 and EP 169 988 called.

Ähnliche Anstrengungen werden unternommen, um die Bedruckbarkeit des Papiers oder Kartons zu verbessern, d. h. gerade das richtige Maß des Einsinkens der Druckfarbe in die obersten Papierschichten herbeizuführen, ohne daß die Druckfarbe seitlich wegdiffundiert und das Druckbild unscharf macht.Similar efforts are being made to improve the Improve the printability of the paper or cardboard, d. H. just the right amount of ink sink in the top layers of paper without causing the ink diffuses away to the side and the print image disarms.

Der zur Verbesserung von Glanz und Glätte einerseits und Bedruckbarkeit andererseits getriebene Aufwand ist immer schon erheblich gewesen. Mit den steigenden Anforde­ rungen an die Papier- bzw. Kartonqualität hat der Aufwand eher noch zugenommen.The one to improve gloss and smoothness on the one hand and printability, on the other hand, is an effort has always been significant. With increasing demands The effort has to do with paper and cardboard quality rather increased.

Der Erfindung liegt die Aufgabe zugrunde, eine weite­ re Möglichkeit der Beeinflussung der Oberfläche von Papier oder Karton zu schaffen, die zu einer Verbesserung der Oberflächenqualität führt und mit relativ geringem Aufwand erreichbar ist.The invention has for its object a wide re possibility of influencing the surface of paper or to create cardboard that will improve Surface quality leads and with relatively little effort is achievable.

Diese Aufgabe wird durch die in den Ansprüchen 1 bis 4 wiedergegebenen Erfindungen gelöst.This object is achieved by the in claims 1 to 4 reproduced inventions solved.

Der gemeinsame Grundgedanke ist hierbei, eine flächi­ ge Behandlung der Oberfläche mit einer elektrischen Entla­ dung durchzuführen, die eine vorteilhafte Veränderung der Oberfläche des Papiers bzw. Kartons ergibt. Diese Behand­ lung kann z. B. die Feuchteeinstellung zumindest teilweise ersetzen oder aber im Zusammenwirken mit den erwähnten bekannten Behandlungen eingesetzt werden.The common basic idea here is a flat treatment of the surface with an electrical discharge to carry out an advantageous change in Surface of the paper or cardboard results. This treatment lung can z. B. the humidity setting at least partially replace or in cooperation with the mentioned known treatments are used.

Die Behandlung von Oberflächen mit einem sogenannten Atmosphären-Plasma geht aus der EP 761 415 A2 hervor. Die Corona-Behandlung ist bei Kunststoffolien allgemein be­ kannt, wie sich aus dem Buch von Joachim Nentwig "Lexikon Folientechnik" (VCH Verlagsgesellschaft mbH, D 6940 Wein­ heim (Bundesrepublik Deutschland) 1991), Seite 80 bis 82, Stichwort "Corona-Behandlung" ergibt.The treatment of surfaces with a so-called Atmospheric plasma can be found in EP 761 415 A2. The Corona treatment is common in plastic films knows how from the book by Joachim Nentwig "Lexikon Film technology "(VCH Verlagsgesellschaft mbH, D 6940 Wein Heim (Federal Republic of Germany) 1991), pages 80 to 82, Keyword "corona treatment" results.

Die Wirkung der erfindungsgemäßen Oberflächen-Vorbe­ handlung kann noch nicht im einzelnen erklärt werden. Es ist aber zu vermuten, daß die durch die Entladung herbei­ geführte elektrische Aktivierung der oberflächennahen Bereiche der Papier- bzw. Kartonmasse bei der anschließen­ den Glättung im Kalander bzw. bei dem anschließenden Druckvorgang eine Rolle spielen.The effect of the surface preparation according to the invention action cannot yet be explained in detail. It  but it can be assumed that they are caused by the discharge guided electrical activation of the surface Connect areas of the paper or cardboard mass to the smoothing in the calender or in the subsequent one Printing process play a role.

Um diese Aktivierung maximal zur Geltung zu bringen, empfiehlt es sich nach Anspruch 5, daß die flächige Ein­ wirkung, sei es des Atmosphären-Plasmas, sei es der Coro­ na-Entladung, kurz vor dem Kalandrieren bzw. Bedrucken stattfindet, so daß noch kein wesentlicher Abbau der Akti­ vierung eingetreten ist, wenn das Papier bzw. der Karton kalandriert bzw. bedruckt werden.To get the most out of this activation, it is recommended according to claim 5 that the flat A effect, be it the atmospheric plasma or the coro na unloading, shortly before calendering or printing takes place, so that there is still no significant reduction in shares vation occurred when the paper or cardboard calendered or printed.

"Kurz vor" soll bedeuten, daß die Entladungsbehand­ lungseinrichtung so dicht an den Kalander bzw. an die Druckmaschine herangerückt werden, wie es konstruktiv möglich ist."Shortly before" is intended to mean that the discharge treatment processing device so close to the calender or to the Printing press can be moved up as it is constructive is possible.

Die Einwirkung der Entladung kann einseitig oder beidseitig erfolgen. Zum Beispiel kann die Bahn vor dem Kalandrieren oder Bedrucken über einen sich quer zur Bahn erstreckenden schmalen Tisch geleitet werden, über welchem die Plasmageneratoren angeordnet sind. Für die Corona- Entladung kann auf einer Seite der Bahn eine quer über diese reichende stangenförmige Elektrode vorgesehen sein, der auf der anderen Seite ein flacher Tisch gegenüber­ steht, wenn die Corona-Entladung nur einseitig wirken soll. Für zweiseitige Einwirkung wird auf beiden Seiten der Bahn eine quer über diese reichende Elektrode ange­ bracht.The effect of the discharge can be unilateral or done on both sides. For example, the web in front of the Calendering or printing on you across the web extending narrow table, over which the plasma generators are arranged. For the corona Unloading can occur across one side of the web this reaching rod-shaped electrode can be provided, on the other side is a flat table stands when the corona discharge only act on one side should. For bilateral action is on both sides a path across this extending electrode brings.
