Abstract

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Erstellung eines Flachbettsiebdruckes auf Gegenständen wie z. B. Textilien, Folien, Kunststoffen, metallischen, gläsernen und/oder hölzernen Gegenständen, Papier, Kartonagen u. dgl., bei dem ein liquides Druckmittel auf ein Druckgewebe (1) aufgebracht und mittels eines bewegbaren Flutrakels (6) als definierte Druckmittelschicht auf dem Druckgewebe (1) abgelegt und mittels eines Druckrakels (5) auf das Druckgewebe (1) eine Kraft ausgeübt wird, wodurch dieses elastisch verformt wird und die definierte Farbschicht mit dem zu bedruckenden Gegenstand in Kontakt kommt. Um dieses Verfahren und diese Vorrichtung wesentlich zu verbessern ist vorgesehen, dass das Flutrakel (6) und dass das Druckrakel (5) das Flutrakel (6) und das Druckrakel in ihrer jeweiligen Arbeitsstellung gemeinschaftlich über das Druckgewebe (1) bewegt werden und zusammen mit dem Flutrakel (6) und dem Druckrakel (5) eine mit dem liquiden Druckmittel befüllte Druckmittelkammer (4) mitbewegt wird, dass das liquide Druckmittel unter einem einstellbaren Druck über einen Kammerauslass (9) bei der Vorwärtsbewegung des Flutrakels (6) und des Druckrakels (5) räumlich vor dem Flutrakel (6) dem Druckgewebe (1) zugeführt wird, dass der Auslass (9) der Druckmittelkammer (4) steuerbar verschließbar ist, dass bezogen auf die Vorwärtsbewegung des Flutrakels (6) und des Druckrakels (5) das räumlich hinter dem Flutrakel (6) angeordnete Druckrakel (5) während der Vorwärtsbewegung des Flutrakels (6) und des Druckrakels (5) die Kraft auf das Druckgewebe (1) ausübt und die definierte Farbschicht mit dem zu bedruckenden Gegenstand in Kontakt kommt (Fig. 1).The invention relates to a method and an apparatus for creating a flat bed screen print on objects such. textiles, foils, plastics, metal, glass and/or wooden objects, paper, cardboard and the like, in which a liquid printing medium is applied to a printing fabric (1) and, using a movable flood blade (6), forms a defined layer of printing medium on the Printing fabric (1) is laid down and a force is exerted on the printing fabric (1) by means of a printing squeegee (5), as a result of which it is elastically deformed and the defined layer of ink comes into contact with the object to be printed. In order to significantly improve this method and this device, it is provided that the flood squeegee (6) and the pressure squeegee (5), the flood squeegee (6) and the pressure squeegee are moved together over the printing fabric (1) in their respective working position and together with the A pressure medium chamber (4) filled with the liquid pressure medium is moved along with the flood squeegee (6) and the pressure squeegee (5), that the liquid pressure medium is under an adjustable pressure via a chamber outlet (9) during the forward movement of the flood squeegee (6) and the pressure squeegee (5 ) is supplied to the printing fabric (1) spatially in front of the flood squeegee (6), that the outlet (9) of the pressure medium chamber (4) can be closed in a controllable manner, that, in relation to the forward movement of the flood squeegee (6) and the pressure squeegee (5), the spatially behind the flood squeegee (6) arranged pressure squeegee (5) during the forward movement of the flood squeegee (6) and the pressure squeegee (5) exerts the force on the printing fabric (1) and the defined color layer with the object to be printed comes into contact (Fig. 1).
