Abstract

A method and device for the continuous production of moulded elements from inorganically bonded materials is presented. This involves compressing a strand of material in a high-pressure compressing unit in such a way that its thickness is less than the set thickness of the finished strand of material and its density is greater than its set density. In the following calibrating device, no active pressure application takes place. It is essential here that, after leaving the high-pressure compressing unit (2), the strand of material runs through a pressureless zone (5) and, following that and immediately before entering the calibrating device (4), is compressed to such an extent that the recovery occurring during running through the pressureless zone (5) is either completely eliminated and the density of the strand of material is greater than the set density of the finished strand of material and the thickness is less than the set thickness of the same when entering the calibrating device (4) or the recovery is eliminated only to such an extent that the thickness of the strand of material corresponds to the set thickness and the density of the strand of material corresponds to the set density of the finished strand of material.
