A process for producing fibrous composite materials from feed stock formed reliminarily from a gypsum binder and chopped cellulose fibers, and saturating the mixture with water to the extent of at least 1.2 times its normal hydrated state, and beating the material to provide a fleece that is then spread on a flat surface and subjected to pressure for a sufficient length of time to drive out a substantial portion of the moisture from the product. The compression step is carried out long enough to achieve a bulk density of approximately 9/10 the dry bulk density of the components prior to hydration.

Process for producing fibrous composites, particularly double floor

In the floor tile for double floor installations, the tile core has a floor covering on its top side, a metal plate on its underside and a lipping on its peripheral edge. The peripheral edge is here provided with a groove (9) which is to receive hot-melt adhesive (3), and the metal plate (8) has an upward edge (4) which grips around the peripheral edge, reaches up to the lower rim of the groove (9) and is flush with a first lipping (7). A second lipping (2), which covers the groove (9) and a part of the upward edge (4) of the metal plate (8), is located on top of the first lipping (7).
