Abstract
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.
