The outer surfaces 11, 12 of material 8 and fillings 10 of the depressions 6 are now at the same level. Now the outer surfaces 11 of the entire metal layer 8 are optionally placed lower (FIG. 2) and thus become the final oleophilic transport surface 13, so that they are e.g. B. 0.03 mm below the outer surface 12 of the ground fillings 15 with a hydrophilic transport surface 14. This can be done in different ways, e.g. B. by etching or electro-chemical removal.

Description
Die Erfindung betrifft ein Verfahren zum Herstellen einer Oberfläche einer Farbwerkwalze nach den Ansprüchen 1 und 2.The invention relates to a method for producing a surface of an inking roller according to
Durch die EP-A-04 86 855 (Stand der Technik nach Artikel 54(3)(4) EPÜ für die Vertragsstaaten CH, DE, FR, GB, IT, LI) ist ein Verfahren zum Herstellen einer Oberfläche einer Farbwerkwalze und eine Oberfläche nach diesem Verfahren bekanntgeworden. Hierbei werden nebeneinanderliegende oleophile und hydrophile Oberflächenanteile einer Farbwerkwalze erzeugt. Zu diesem Zweck wird auf eine metallische Oberfläche einer Walze eine oleophile Metallschicht aufgebracht, in die Rillen eingearbeitet werden. Diese Rillen werden mit einem hydrophilen Keramikmaterial vollgefüllt. Die so entstandene Oberfläche der Farbwerkwalze wird so bearbeitet, daß oleophile und hydrophile Flächenanteile auf gleichem Niveau liegen. In die oleophilen Flächenanteile werden dann eine Vielzahl von Näpfchen eingebracht. Die Erzeugung von sog. Haschuren, bei denen die farbführende Schicht zwischen die Walzenoberfläche spiralförmig umfahrenden freistehenden Stegen insgesamt tiefer gelegt und nicht durch eine Vielzahl Querstege abgeteilt wird, ist in dieser Druckschrift überhaupt nicht angesprochen.EP-A-04 86 855 (state of the art according to Article 54 (3) (4) EPC for the contracting states CH, DE, FR, GB, IT, LI) is a method for producing a surface of an inking roller and a surface became known by this method. Here, oleophilic and hydrophilic surface portions of an inking roller lying side by side are generated. For this purpose, an oleophilic metal layer is applied to a metallic surface of a roller, into which grooves are incorporated. These grooves are filled with a hydrophilic ceramic material. The resulting surface of the inking roller is processed in such a way that oleophilic and hydrophilic areas are at the same level. A large number of cells are then introduced into the oleophilic areas. The production of so-called hashes, in which the ink-guiding layer between the roller surface of the free-standing webs which spiral around it is lowered overall and is not divided by a large number of cross webs, is not addressed at all in this publication.
Die EP-A-03 24 939 beschreibt ein Verfahren zur Herstellung einer Rasterwalze. Hierbei wird auf den imprägnierten Grundkörper der Walze eine Kupferschicht aufgebracht, in die Näpfchen eingearbeitet werden, deren Stege von einer Keramikschicht überdeckt sind.EP-A-03 24 939 describes a method for producing an anilox roller. Here, a copper layer is applied to the impregnated base body of the roller, in the wells are incorporated, the webs of which are covered by a ceramic layer.
Der Erfindung liegt die Aufgabe zugrunde, eine Oberfläche für eine Farbwerkwalze mit einer Oberfläche zu schaffen, die hydrophile und oleophile Flächenanteile aufweist und ein Verfahren zur Herstellung einer Oberfläche einer solchen Walze.The invention has for its object to provide a surface for an inking roller with a surface which has hydrophilic and oleophilic surface portions and a method for producing a surface of such a roller.
Die Aufgabe wird gelöst mit den Verfahrensschritten des kennzeichnenden Teils des Anspruches 1 und den Merkmalen des kennzeichnenden Teils des Anspruches 2.The object is achieved with the method steps of the characterizing part of claim 1 and the features of the characterizing part of
Die mit der Walze erzielbaren Vorteile bestehen insbesondere darin, daß eine Walze geschaffen wird, bei der die oleophilen Kleinflächen aus einem oleophilen Metall bestehen können und nach Auschwemmung oder chemischer Abtragung wieder leicht bis zur Soll-Vertiefung aufgetragen werden können, z. B. durch Materialauftrag nach einem elektro-chemischen Verfahren oder aber auch umgekehrt, falls die tragenden hydrophilen Flächenanteile, die mit den Rakeln in Berührung stehen, stärker abgenutzt sind, die tieferliegenden oleophilen Flächenanteile. In diesem Falle werden die oleophilen Flächenanteile elektro-chemisch soweit abgetragen, bis der Soll-Abstand von oleophiler zu hydrophiler Oberfläche unmittelbar benachbarter Flächenanteile wieder erreicht ist. Die Lebensdauer der Walze kann so weiter verlängert werden.The advantages that can be achieved with the roller are, in particular, that a roller is created in which the small oleophilic surfaces are made of an oleophilic metal can exist and after flushing or chemical ablation can easily be applied again to the target deepening, e.g. B. by applying material by an electro-chemical process or vice versa, if the load-bearing hydrophilic areas that are in contact with the doctor blades are more worn, the deeper oleophilic areas. In this case, the oleophilic areas are electrochemically removed until the desired distance from the oleophilic to the hydrophilic surface of immediately adjacent areas is reached again. The life of the roller can be extended further.

Auf z. B. einer Mantelfläche 1 einer Stahlwalze 2 oder eines auf eine Mantelfläche 1 eines auf eine Walze aufschiebbaren Rohres, wird eine z. B. 0,6 mm dicke Metallschicht 3 aus einem oleophilen Material, z. B. Kupfer, flammaufgespritzt, eletro-chemisch aufgebracht oder aufplattiert.On z. B. a lateral surface 1 of a
Anschließend wird die oleophile Oberfläche 4 der Metallschicht 3 mit einer Anzahl von Vertiefungen 6 versehen, die so tief sind, daß sie entweder bis zur Mantelfläche 1 führen oder innerhalb der Dicke der oleophilen Metallschicht 3 enden. Diese Vertiefungen 6 können einen beliebigen Querschnitt aufweisen und auf verschiedenste Art hergestellt werden, z. B. durch Lasern, Drehen, Rollen, Gravieren usw. Die Vertiefungen 6 können z. B. als ein oder mehrstufige schraubenförmige Rillen 7 mit z. B. einer Steigung von 1 mm, einer Breite von z. B. 0,5 mm und 0,15 mm Tiefe ausgebildet sein.Subsequently, the oleophilic surface 4 of the
Die Rillen 7 können gleichläufig aber auch gegenläufig zueinander sein. Die Vertiefungen 6 können aber auch die verschiedenartigsten Querschnitte aufweisen, z. B. rund, rautenförmig oder auch länglich sein.The grooves 7 can be in the same direction but also in opposite directions to one another. The recesses 6 can also have a wide variety of cross sections, z. B. be round, diamond-shaped or elongated.
Nach dem Einbringen der Vertiefungen 6 in die oleophile Metallschicht 3 werden zumindest die Vertiefungen 6 mit einem weitgehend gegen Abrieb resistenten und hydrophilen Material 8 vollständig aufgefüllt, z. B. mittels des Flammspritzverfahrens.After the indentations 6 have been introduced into the
Das weitgehend abriebresistente Material 8 besteht z. B. aus Keramik (CR₂ O₃). Da das gezielte Füllen der Vertiefungen 6 nicht möglich ist, wird es sich nicht vermeiden lassen, daß die gesamte Oberfläche 4 der oleophilen Metallschicht 3 mit zumindest einer dünnen Schicht 9 des Materials 8 bedeckt ist. Diese Schicht 9 des Materials 8 wird nun soweit entfernt, z. B. abgeschliffen, daß das Material der Metallschicht 3 - unterbrochen jeweils durch die Auffüllungen 10 der Vertiefungen 6 - vollständig freiliegt. Die Außenflächen 11, 12 von Material 8 und Auffüllungen 10 der Vertiefungen 6 liegen nun auf gleichem Niveau. Nun werden die Außenflächen 11 der gesamten Metallschicht 8 wahlweise tiefer gelegt (Fig. 2) und werden so zur endgültigen oleophilen Transportfläche 13, so daß sie z. B. 0,03 mm unterhalb der Außenfläche 12 der abgeschliffenen Auffüllungen 15 mit einer hydrophilen Transportfläche 14 liegen. Dieses kann auf verschiedene Weise geschehen, z. B. durch Ätzen oder elektro-chemisches Abtragen.The largely abrasion-resistant material 8 consists, for. B. made of ceramic (CR₂ O₃).
