Abstract

The known method of producing the required scratched surface finish on the tiles is to stretch a wire across the mouth through which the tiles are extruded so as to remove uncontrolled amounts from their upper surfaces. By the invention, the wire is replaced by a cylindrical brush (7) which rotates against the surface of the newly-extruded length of tiles. There follows a dampened cylinder of sponge (8) to stick back any particles the brush has loosened; it does this without spoiling the general effect of the brushing. The appearance of the finished surface can be varied by changing the brush and/or sponge for another of a different texture, and/or by reversing the rotation of one or both of them. The sponge (8) can also be rotated and a watering device (9) can be positioned over the sponge.

Description

Vorrichtung zur Erzeugung einer Streifenstruktur auf Platten Die Erfindung betrifft eine Vorrichtung zur Erzeugung einer Streifenstruktur auf der Oberfläche stranggepreßter keramischer Platten. Device for producing a strip structure on plates Die The invention relates to a device for producing a strip structure on the Surface of extruded ceramic plates.

Ublicherweise wird eine streifenförmige unregelmäßige Struktur auf der Oberfläche stranggepreßter Biberschwanz-Dachziegel durch einen dünnen Draht erzeugt, der vor das Mundstück gespannt wird und der die oberste Schicht des plastischen keramischen Stranges abschält. Nachteilig daran ist, daß die abgeschälte Schicht durch zusätzliche Vorrichtungen oder von Hand abgenommen werden muß und daß das Aussehen der Streifenstruktur praktisch nicht verändert und beeinflußt werden kann. Usually a strip-shaped, irregular structure appears the surface of extruded beaver tail roof tiles through a thin wire generated, which is stretched in front of the mouthpiece and which is the top layer of the plastic peel off the ceramic strand. The disadvantage of this is that the peeled off layer must be removed by additional devices or by hand and that the The appearance of the strip structure can practically not be changed or influenced.

Der Neuerung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs geschilderten Art zu schaffen, mit der verschieden aussehende Arten von Streifenstrukturen auf der Oberfläche keramischer Platten hergestellt werden können. The innovation is based on the task of a device of the initially to create the described type, with the different looking types of strip structures can be produced on the surface of ceramic plates.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, daß dem Mundstück einer Strangpresse in einem Bereich, der eine Einwirkung auf die Oberfläche des platischen keramischen Stranges gestattet, ein Kamm oder eine Bürste und ein Schwamm oder ein anderer weicher Körper nachgeordnet sind. The object is achieved according to the invention in that the mouthpiece an extruder in an area that has an impact on the surface of the ceramic strand, a comb or a brush and a sponge or another soft body are subordinated.

In einer besonders vorteilhaften Ausführungsform der Vorrichtung nach der Erfindung hat die Bürste die Form einer Walze, welche sich gleich- oder gegenläufig zur Bewegung des keramischen Stranges bewegt. Dadurch kann einerseits eine zu starke Verschmutzung der Bürste vermieden werden. Andererseits kann auch durch dtp Wahl dpr nrehrichtuna und der Drehzahl das Aussehen der . -aratenv etruktur verändert werden. Außerdem kann durch Veränderung der Borstenbüschellänge statt einer regelmäßigen auch eine besonders unregelmäßige Streifenstruktur erreicht werden.In a particularly advantageous embodiment of the device according to the invention, the brush has the shape of a roller which moves in the same direction or in opposite directions to the movement of the ceramic strand. In this way, on the one hand, excessive contamination of the brush can be avoided. On the other hand, the appearance of the . -aratenv et structure to be changed. In addition, by changing the length of the bristle tufts, a particularly irregular stripe structure can be achieved instead of a regular one.

In weiterer Ausgestaltung der Erfindung hat der nachgeordnete Schwamm gleichfalls die Form einer sich drehenden Walze. In a further embodiment of the invention, the downstream sponge also in the form of a rotating roller.

Auch hier kann durch die Veränderung der Drehrichtung, der Drehzahl und der Schwammoberfläche die Art und Stärke des Verwischens der Streifenstruktur verändert werden.Here, too, by changing the direction of rotation, the speed and the sponge surface, the type and strength of the blurring of the stripe structure to be changed.

Schließlich sieht die Erfindung vor, daß das endgültige Aussehen der Streifenstruktur auch durch eine Bewässerungseinrichtung über der Schwammwalze beeinflußt werden kann. Finally, the invention provides that the final appearance the strip structure also by an irrigation device above the sponge roller can be influenced.

Die Erfindung ist in der nachstehenden Beschreibung anhand der Zeichnung in zwei Ausführungsformen schematisch dargestellt. The invention is illustrated in the following description with reference to the drawing shown schematically in two embodiments.

Fig. 1 zeigt im Längsschnitt den Preßkopf 1 der Strangpresse mit dem Mundstück 2 , aus welchem der plastische, keramische Strang 3 ausgepreßt wird. Auf der Oberfläche wird dabei zuerst durch die Bürste 4 eine Aufrauhung erzeugt, die danach durch den Schwamm 5 wieder verwischt wird. Fig. 1 shows the press head 1 of the extruder in longitudinal section the mouthpiece 2, from which the plastic, ceramic strand 3 is pressed. A roughening is first created on the surface by the brush 4, which is then blurred again by the sponge 5.

Fig. 2 zeigt im Längsschnitt eine besonders vorteilhafte Ausführungsform der erfindungsgemäßen Vorrichtung. Dabei wird die Oberfläche des Stranges 6 durch die rotierende Bürste 7 aufgerauht und durch die ebenfalls rotierende Schwammwalze 8 wieder verwischt. Eine Bewässerungseinrichtung 9 sorgt dafür, daß die Schwammwalze 8 immer ausreichend feucht gehalten ist. Fig. 2 shows a particularly advantageous embodiment in longitudinal section the device according to the invention. The surface of the strand 6 is thereby through the rotating brush 7 roughened and by the also rotating sponge roller 8 blurred again. An irrigation device 9 ensures that the sponge roller 8 is always kept sufficiently moist.

Die Teile der Vorrichtung sind in einem gemeinsamen Rahmen gelagert. Gegebenenfalls kann der Rahmen auch einen Bestandteil der Strangpresse bilden.The parts of the device are mounted in a common frame. If necessary, the frame can also form part of the extrusion press.
