Die Erfindung betrifft eine Anlage und ein Verfahren zur Herstellung von Schaumstoffplatten in einem kontinuierlichem Schaumprozess mit folgenden Schritten: DOLLAR A - Erfassung des Ist-Aufschäumprofils des Schaumstoffs, DOLLAR A - Bestimmung einer Stellgröße für den Schaumprozess in Abhängigkeit von einer Abweichung des Ist-Aufschäumprofils vom Soll-Aufschäumprofil. In a continual process to manufacture polyurethane foam rubber blocks a profiled quantity of the basic foam ingredient is placed on a conveyer belt and the profile contours are registered by a suitable measuring device. This is followed by the determination of a target parameter e.g. speed of conveyer belt advance and/or rate of additive introduction, by comparison of the profile contour with a target value. Also claimed is a commensurate polyurethane foam rubber manufacturing assembly.
