ABSTRACT:
A method of manufacturing shaped bodies, in particular boards, out of gypsum, water of hydration and comminuted fibers containing lignocellulose and/or cellulose is described in which all components are combined into a single starting mixture and at least one water saturated, essentially ground-moist, light aggregate is dispersed in this mixture as a fixed pore former. From this starting mixture there is formed a mat which is built up symmetrically in cross-section by means of a single double-sided wind sifting scattering process wherein the light aggregates are located in the central layer. This mat which is built up symmetrically in cross-section is pressed while supplying heat.
