Abstract (en)
[origin: ES8604042A1] The method of making a fibre reinforced concrete material includes sprinkling chopped fibres on the surface of a layer of the material mixed with water, as it is advanced on a conveyor belt. The water content is maintained at a required level, and the layer is kept to a required thickness. The fibres are discharged from an overhead supply duct, and compressed into the surface. - The fibres are suitably aligned and evenly spread by a resilient distributor tool. In addition to the chopped fibres, endless fibres are also added. After the layer has been extruded onto the belt, the fibres can be pressed into it more than once in successive layers. The layer can be wider than the finished width, and the projecting edges are folded over. Cement can be added to any parts in which fibres have not been embedded, or they can be covered.

Abstract (de)
Es wird ein Verfahren zur kontinuierlichen Herstellung von Platten und/oder Formkörpern aus faserbewehrten hydraulisch abbindenden Massen beschrieben, bei dem auf eine durch ein Band kontinuierlich fortbewegte Unterlage die Masse in einer bestimmten Dicke über die gesamte Breite der zu bildenden Platte maßgerecht aufgebracht wird. Auf die Oberfläche der sich mit der Unterlage fortbewegende Masse werden aus einer Schneidvorrichtung Faserschnitzel gezielt aufgestreut und diese anschliessend durch ein über die gesamte Breite der Masse gleichmässig wirkendes Werkzeug in die Masse eingebaut. Die Rohplatte kann in ihrem noch verformbaren Zustand weiter verarbeitet und in eine gewünschte Endform überführt werden.
