DEVICE AND METHOD FOR PRODUCING SOLID AND HOLLOW GYPSUM WALLBOARD ELEMENTS IN QUICK SUCCESSION

The invention relates to a device and a method for producing solid and hollow gypsum construction elements, comprising the following features: * a) a gypsum silo (6) from which gypsum is conveyed to a gypsum mixer (4) where process water is also added, * b) a moulding box (3) for moulding gypsum construction elements, comprising a plurality of parallel-lying moulding chambers (19) with grooved webs (23) on each of the two end faces, each moulding chamber (19) being provided with a displaceable bottom rail (24) and said bottom rail (24) additionally comprising web-like elevations for the purpose of generating profiled structures, * c) a number of drive cylinders (21) for the vertical displacement of cavity pins (17) in moulding chambers (19), * d) a plane cross-bar (20) which can be guided in guiding units (18) over the moulding box (3), for smoothing the surface of the gypsum wallboard elements, * e) a number of drive cylinders (22) for vertically ejecting finished gypsum wallboard elements, and * f) a rotating device (26) allowing two moulding boxes (3) to be filled within a short time interval.
