The present invention is directed to improvements in apparatus and proces for the continuous production of inorganically bonded materials, the apparatus and process providing a pressureless transition zone without the action of pressure on a continuous sheet of material arranged between a high-pressure compression unit and the calibrating unit, and where the calibrating unit is immediately preceded by a recompression unit, which applies an active pressure on the continuous sheet of material after it passes through the pressureless zone and before it enters the calibrating unit and where this active pressure is sufficiently high that the nominal thickness of the continuous sheet of material is equal to or less than the finished continuous sheet of material and nominal density of the continuous sheet of material are equal to or greater than the density of the finished continuous sheet of material.

Process and equipment for the continuous production of inorganically

A method for controlling the manufacturing process in the continuous prodion of gypsum-cemented workpieces utilizing a belt-type press or similar equipment including a number of press segments joined in tandem relationship. Utilizing this press, the gypsum undergoing hydration is compacted until the end of the hydration is reached. The swelling pressure created in the course of the hydration is measured and utilized to control the manufacturing process.
