Description
Die Erfindung betrifft eine Walze für ein Farbwerk einer Druckmaschine gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a roller for an inking unit a printing press according to the preamble of Claim 1.
Eine gattungsgemäße Rasterwalze ist durch die EP 02 87 002 A2 bekanntgeworden. Sie besteht aus einem Stahlzylinder, auf dessen Mantel eine Korrosionsschutzschicht aus Metall, und auf dieser wiederum eine Metallkeramikschicht aufgebracht ist. Die Mantelfläche ist mit einer Vielzahl von Näpfchen versehen.A generic anilox roller is through the EP 02 87 002 A2 has become known. it consists of a steel cylinder, on the jacket of which one Corrosion protection layer made of metal, and on this again a metal ceramic layer is applied. The outer surface is with a variety of cups Mistake.
Aus der EP 05 11 543 A1 ist eine Rasterwalze bekannt, deren Mantelfläche aus hydrophilen und oleophilen Flächenanteilen zusammengesetzt ist.An anilox roller is known from EP 05 11 543 A1, the surface of which is made of hydrophilic and oleophilic Area shares is composed.
Der Erfindung liegt die Aufgabe zugrunde, eine Farbwerkwalze zu schaffen, deren Mantelfläche hydrophile und oleophile Flächenanteile aufweist und ein Verfahren zur Herstellung eines derartigen Mantels und Mantelfläche.The invention has for its object a To create inking roller, the outer surface of which is hydrophilic and has oleophilic areas and a Process for producing such a jacket and Lateral surface.
Die Aufgabe wird gelöst mittels der Verfahrensschritte des kennzeichnenden Teils des Patentanspruches 8 und den Merkmalen des kennzeichnenden Teils des Patentanspruches 1.The task is solved by means of the process steps of the characterizing part of claim 8 and the Features of the characterizing part of the claim 1.
Ein Ausführungsbeispiele werden im folgenden näher beschrieben.An exemplary embodiment will be described in more detail below described.
Auf einer z. B. dünn mit einem Nichteisenmetall, z. B. Nickel beschichteten Mantelfläche 1 einer Stahlwalze 2 oder einer auf eine Mantelfläche 1 eines auf einen Walzenkern auf schiebbaren Rohres, wird mittels sog. Plasmaspritzen (thermische Spritzen) ein Mischung aus Metallkeramik (z. B. Cr2O3) und metallischem Kupfer (Cu) aufgebracht. Das Cr2O3 hat hydrophile und das Cu oleophile Eigenschaften.On a z. B. thin with a non-ferrous metal, e.g. B. nickel-coated surface 1 of a steel roller 2 or on a surface 1 of a tube which can be pushed onto a roller core, a mixture of metal ceramic (e.g. Cr 2 O 3 ) and metallic copper (so-called plasma spraying (thermal spraying)) Cu) applied. The Cr 2 O 3 has hydrophilic and the Cu oleophilic properties.
Beim Plasmaspritzen wird dabei als Spritzpulver erfindungsgemäß ein hydrophiles Metalloxyd z. B. Cr2O3 oder Oxide des Aluminiums oder Zirkons verwendet, das mit einem oleophilen Metall, z. B. Kupfer umhüllt ist. Die Metalloxydpartikel können beispielsweise zwischen 20-45 µm, die sie umhüllende oleophile Metallschicht, - z. B. aus Kupfer -, zwischen 5 und 45 µm dick sein.In plasma spraying, a hydrophilic metal oxide z. B. Cr 2 O 3 or oxides of aluminum or zircon used with an oleophilic metal, for. B. copper is coated. The metal oxide particles can for example between 20-45 microns, the enveloping oleophilic metal layer, -. B. of copper, between 5 and 45 microns thick.
Man wählt die Metallumhüllungsschichtdicke so, daß man einen gewünschten oleophilen Flächenanteil, z. B. 5% an der Mantelfläche der Farbwerkwalze erhält.You choose the metal cladding layer thickness so that a desired oleophilic area fraction, e.g. B. 5% receives the outer surface of the inking roller.
Nach Auftreffen des heißen Metall-Keramik-Plasmas auf die Mantelfläche 1 der Stahlwalze 2 bilden sich einzelnstehende oder zusammenhängende Inseln aus dem oleophilen Metall, mit dem die Keramikpartikel umhüllt waren, z. B. aus oleophilem Kupfer, zwischen ihnen befindet sich das hydrophile Keramik. Die Mantelfläche der Farbwerkwalze weist ein also willkürliches Flächengemisch aus dicht an dicht liegenden, kleinen oleophilen Metallflächen und hydrophilen Keramikflächen auf.After the hot metal-ceramic plasma strikes the outer surface 1 of the steel roller 2 , individual or connected islands are formed from the oleophilic metal with which the ceramic particles were coated, for. B. from oleophilic copper, between them is the hydrophilic ceramic. The lateral surface of the inking roller has an arbitrary mixture of surfaces made up of small oleophilic metal surfaces and hydrophilic ceramic surfaces.
Anschließend wird die Keramik/Metalloberfläche der Walze geschliffen, danach poliert und schließlich mit Rasternäpfchen versehen. Das Einbringen von Rasternäpfchen mittels Laserstrahlung oder Gravur ist bekannt. Nach dem Einbringen der Näpfchen wird die Walze noch einmal geschliffen bzw. poliert.Then the ceramic / metal surface of the Ground roller, then polished and finally provided with grid cups. The introduction of Is using laser radiation or engraving known. After inserting the cells, the roller sanded or polished again.
