A method and apparatus for continuously producing molded member, especially sheets, from a mixture of gypsum and fibrous material. In a first mixing stage, measured-out quantities of gypsum and fibrous material are thoroughly mixed together, with the dry mixture being weighed and subsequently moistened in a second mixing stage by supplying water thereto in conformity to the weight of the dry mixture. The moistened mixture is subsequently dispersed onto a support to form molded members, with the surface of each molded member being additionally moistened, and the latter then being compacted. To achieve higher strength, the mas flow of the gypsum/fibrous material mixture is divided into independent partial mass flows that are dispersed in layers to form the multi-layer molded member, with each partial mass flow forming one of the layers of the molded member. Each deposited layer is additionally moistened with water, with the total quantity of water supplied to a given molded member equalling up to about 25% more than the stoichiometric quantity of water required for curing the gypsum/fibrous material mixture. |
