Abstract
Description
Vorliegende Erfindung betrifft eine Rakeleinrichtung einer Druckmaschine, umfassend eine Negativrakel zum Abrakeln einer Walze.The present invention relates to a squeegee device of a printing press, comprising a negative squeegee for doctoring a roller.

Der Erfindung liegt die Aufgabe zugrunde, eine weitere Rakeleinrichtung zu schaffen.The invention has for its object to provide a further doctor device.
Diese Aufgabe wird durch eine Rakeleinrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die erfindungsgemäße Rakeleinrichtung einer Druckmaschine umfasst eine Negativrakel zum Abrakeln einer Walze und eine Positivrakel, die der Negativrakel in Drehrichtung der Walze nachgeordnet ist.This object is achieved by a doctor device with the features of
Bei einer Weiterbildung der erfindungsgemäßen Rakeleinrichtung sind die Negativrakel und die Positivrakel in einer gemeinsamen Klemmeinrichtung festgeklemmt.In a development of the doctor device according to the invention, the negative doctor blade and the positive doctor blade are clamped in a common clamping device.
Bei einer weiteren Weiterbildung sind die Negativrakel und die Positivrakel zusammen als eine einstückige Doppelrakel ausgebildet. Die Doppelrakel, welche ein die Negativrakel bildendes Rakelblatt und ein die Positivrakel bildendes Rakelblatt umfasst, besteht aus einem einzigen Bauteil. Dieses Bauteil kann gabelartig profiliert sein, wobei der eine Gabelarm die Negativrakel bildet und der andere Gabelarm die Positivrakel bildet. Das Bauteil kann ein Blechteil oder ein Kunststoffteil sein. Das Bauteil kann auch ein Verbundstoff in Sandwichbauweise sein, wobei z. B. die Negativrakel aus Blech besteht und die Positivrakel aus Kunststoff besteht, der mit dem Blech fest verbunden, z. B. verklebt ist.In a further development, the negative doctor blade and the positive doctor blade are formed together as a one-piece double doctor blade. The double doctor blade, which comprises a doctor blade forming the negative doctor blade and a doctor blade forming the positive doctor blade, consists of a single component. This component can be profiled like a fork, with one fork arm forming the negative squeegee and the other fork arm forming the positive squeegee. The component may be a sheet metal part or a plastic part. The component may also be a composite in sandwich construction, wherein z. B. the negative squeegee is made of sheet metal and the positive squeegee is made of plastic, which is firmly connected to the sheet, z. B. is glued.
Bei einer weiteren Weiterbildung weist die Positivrakel einen Anstellwinkel von weniger als 45° auf.In a further development, the positive doctor blade has an angle of attack of less than 45 °.
Bei einer weiteren Weiterbildung weist die Positivrakel eine Hakenform auf.In a further development, the positive doctor blade has a hook shape.
Bei einer weiteren Weiterbildung begrenzt die Negativrakel eine Vorratskammer für Beschichtungsflüssigkeit.In a further development, the negative squeegee limits a storage chamber for coating liquid.
Bei einer weiteren Weiterbildung ist die Rakeleinrichtung Bestandteil eines Anilox-Farbwerks.In a further development, the doctor device is part of an anilox inking unit.
Weitere konstruktiv und funktionell vorteilhafte Weiterbildungen ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels und der zugehörigen Zeichnung.Other structurally and functionally advantageous developments will become apparent from the following description of an embodiment and the accompanying drawings.
