Abstract

In einem Verfahren zum fortlaufenden Formen von Platten aus einer geschäumten keramischen Formmasse (22), welche in einem Mischer (10) aus einem tonhaltigen Schlicker, aus einem Schaum und ggfs. aus Zusatzstoffen gebildet wird und sich aus einem am Mischer (10) vorgesehenen Auslaß (21) in Formen (4) ergießt, werden die Formen (4) mittels eines unterhalb des Auslasses (21) laufenden Förderbandes (3) gebildet, indem die beiden längsverlaufenden Ränder (32,33) des Förderbandes (3) auf einer Strecke, die vor dem Auslaß (21) beginnt und mit Abstand vom Auslaß (21) hinter diesem endet, aufgerichtet und durch zwischen die hochgestellten Ränder (32,33) eingeklemmte, lose Trennwände (6) auf Abstand voneinander gehalten werden, wobei die Trennwände(6) mindestens so hoch sind wie die zu gießenden Platten .

In a process for the continuous molding of sheets from a foamed ceramic molding compound (22) which is formed in a mixer (10) from a clay-containing slip, from a foam and, if appropriate, from additives, and from an outlet provided on the mixer (10) (21) pours into molds (4), the molds (4) are formed by means of a conveyor belt (3) running underneath the outlet (21), in that the two longitudinal edges (32, 33) of the conveyor belt (3) over a distance, which begins in front of the outlet (21) and ends at a distance from the outlet (21) behind it, is erected and is kept at a distance from one another by loose partition walls (6) clamped between the raised edges (32, 33), the partition walls (6 ) are at least as high as the slabs to be cast.
