Thereafter, the container assembly 1 with its base plate 2 placed on the slider 21, wherein the bolts 28 to 30 provided holes pierced, which are introduced into the mounting bracket 16 to 18 and the base plate 2.

Im Unterschied zu dem gezeigten Ausführungsbeispiel könnten die Bolzen ein Gewinde aufweisen und Schraubbefestigungen vorgesehen sein, welche ein Abheben der Behälteranordnung 1 von dem Schieber 21 verhindert, jedoch genügend Spiel läßt, so daß der Schieber entlang den Langlöchern 23 bis 25, geführt durch die Bolzen 28 bis 30, verschoben werden kann.In contrast to the embodiment shown, the bolts could have a thread and screw fasteners may be provided which prevents lifting of the container assembly 1 of the slider 21, but leaves enough play, so that the slider along the slots 23 to 25, guided by the bolts 28th until 30, can be moved.

Die einzelnen Behälter 5 bis 10 der Behälteranordnung 1 können mit einem Dekormaterialvorrat befüllt werden, wobei z.B. in die Behälter 6 bis 10 ein weißes Dekormaterial und den Außenbehälter 5 sowie den inneren Behälter 10 ein schwarzes Dekormaterial einfüllbar ist.The individual containers 5 to 10 of the container arrangement 1 can be filled with a decor material supply, wherein e.g. in the container 6 to 10, a white decorative material and the outer container 5 and the inner container 10, a black decorative material can be filled.

Im Betriebsfall wird die Vorrichtung auf den oben erwähnten Fliesenpreßstempel aufgesetzt, wobei die Schablonenstegabschnitte 34 bis 37 und der Ringsteg 33 über den größten Teil der Steglänge mit ihrem unteren Rand in Anlage gegen den Preßstempel kommen. Eine dem Querschnitt des Außenbehälters 5 entsprechende Außenbegrenzung ist dadurch gebildet, daß der genannte Fliesenpreßstempel in eine das Preßvolumen seitlich begrenzende Führung abgesenkt ist.In the operating case, the device is placed on the above-mentioned Fliesenpreßstempel, wherein the template web sections 34 to 37 and the annular web 33 come over the greater part of the web length with its lower edge in abutment against the ram. An outer boundary corresponding to the cross-section of the outer container 5 is formed in that said tile press ram is lowered into a guide laterally delimiting the pressing volume.

Durch diese seitliche Begrenzung, den Ringsteg 33 und die Schablonenstegabschnitte 34 bis 37 sind auf dem Fliesenstempel insgesamt fünf gegeneinander abgegrenzte Felder 41 bis 45 gebildet, wie Fig. 7 zu entnehmen ist. Der Zusammenhang zwischen einem inneren und äußeren Teil des Feldes 41 ist durch die genannten Ausnehmungen 38 bis 40 in den Schablonenstegabschnitten bzw. dem Ringsteg hergestellt.Due to this lateral boundary, the annular web 33 and the template web sections 34 to 37, a total of five mutually delimited fields 41 to 45 are formed on the tile stamp, as shown in FIG. 7 can be seen. The relationship between an inner and outer part of the panel 41 is made by said recesses 38 to 40 in the template web sections and the annular web, respectively.

Zum Auftragen von Dekormaterial wird der Schieber über die Länge der Langlöcher 23 bis 25 bewegt, wobei das Lochraster 22 des Schiebers 21 zur Deckung mit dem Lochraster 20 der Grundplatte 2 gelangt. Damit kann fließfähiges Dekormaterial auf den durch den Fliesenpreßstempel gebildeten Schichtträger gelangen. Das verhältnismäßig enge Lochraster sorgt für eine gleichmäßige Verteilung des Materials auf dem Schichtträger.For applying decorative material, the slider is moved over the length of the elongated holes 23 to 25, wherein the hole pattern 22 of the slider 21 comes to coincide with the hole pattern 20 of the base plate 2. This can flowable decorative material on the formed by the Fliesenpreßstempel layer carrier. The relatively narrow pitch pattern ensures a uniform distribution of the material on the substrate.

Gemäß der oben beispielhaft angegebenen Befüllung der Behälter 5 bis 10 können die Felder 42 bis 45 mit weißer Dekormasse belegt werden, während auf das Feld 41 schwarze Dekormasse gelangt.According to the above-exemplified filling of the container 5 to 10, the fields 42 to 45 can be covered with white decorative composition, while on the field 41 black decorative mass passes.

Zur Dosierung der aufgetragenen Materialmenge wird der Schieber über eine vorbestimmte Zeit im Öffnungszustand belassen und dann zum Verschließen der Auslaßöffnungen der Behälter 5 bis 10 wieder um die Länge der Langlöcher 23 bis 25 verschoben.For metering the amount of material applied, the slide is left for a predetermined time in the open state and then moved to close the outlet openings of the container 5 to 10 again by the length of the slots 23 to 25.

In den jeweiligen Behältern 5 bis 10 kann ein für eine größere Zahl von Beschichtungen ausreichender Dekormaterialvorrat enthalten sein.In the respective containers 5 to 10, a sufficient for a larger number of coatings decor material supply may be included.

Die Durchlaufmenge des fließfähigen Füllmaterials je Zeiteinheit ist weitgehend unabhängig von der Füllhöhe. Da das verwendete Material zwar fließfähig, aber dennoch im festen Zustand ist, sind Schweredruckeinflüsse auf die Durchlaufmengen von untergeordneter Bedeutung. Die Verwendung einer die Durchlaufmenge beeinfllussenden Vibrationseinrichtung ist denkbar.The flow rate of the flowable filling material per unit time is largely independent of the filling level. Although the material used is flowable, but nevertheless in the solid state, gravitational influences on the flow rates are of secondary importance. The use of a flow rate influencing vibration device is conceivable.

Im Unterschied zu dem gezeigten Ausführungsbeispiel könnte die Schieberbetätigung statt von Hand über eine mechanische Betätigungseinrichtung automatisch unter geeigneter Bemessung der Öffnungszeit durchgeführt werden.In contrast to the embodiment shown, the slide operation could be carried out automatically instead of manually via a mechanical actuator with appropriate design of the opening time.

Als Dekormaterial wird vorzugsweise Sprühgranulat verwendet, wobei die Granulatteilchen aus der gleichen Masse wie die Fliesen bestehen, jedoch gefärbt sind.As a decorative material preferably spray granules is used, wherein the granules of the same mass as the tiles, but are colored.

Die Behälter- und Schablonenteile werden vorzugsweise aus Messing hergestellt, das für die verwendeten Dekormaterialien gute Gleiteigenschaften besitzt und sich beim Verbinden von Behälterteilen durch Löten nicht verzieht.The container and template parts are preferably made of brass, which has good sliding properties for the decorative materials used and does not distort when connecting container parts by soldering.

Wie aus Fig. 8 hervorgeht, kann die beschriebene Vorrichtung nahe einer Presse für die Herstellung von Fliesenrohlingen installiert sein, wobei eine Transporteinrichtung vorgesehen ist, welche das Preßwerkzeug zur Beschichtung des unteren Preßstempels der Vorrichtung zuführt und wieder zurück in die Presse transportiert.As is apparent from Fig. 8, the device described can be installed near a press for the production of tile blanks, wherein a transport device is provided, which feeds the pressing tool for coating the lower punch of the device and transported back into the press.
