Abstract

PURPOSE:To prevent air bubbles from mixing by a method wherein the filling of gypsum is done by flowing down kneaded gypsum in a mold through a bung hole at the bottom of a kneaded gypsum container. CONSTITUTION:Gypsum powder, foaming agent and water are filled from an opening 31 in a storage container 3 and agitated and mixed through the pivotting with rotating shafts 21 and 22 into paste-like kneaded gypsum P. The kneaded gypsum P is discharged outside the storage container 3 through a bung hole 32 made at the bottom of the kneaded gypsum storage container 3. Its discharge rate is controlled by actuating a pinch valve 5. The kneaded gypsum P, which has passed through the pinch valve 5, passes through a net member 6 and fills a mold 7. Since the kneaded gypsum, which is stagnant at the bottom of the container, of the kneaded gypsum housed in the container flows down, the kneaded gypsum to fill the mold contains no large air bubbles.
