ABSTRACT:
A method for manufacturing of slabs of granulated stone material and/or sands bound with a resin which can be hardened, and preferably hot with the aid of a catalyst. The mixture of granulated material and/or sand and resin is deposited as a layer of uniform thickness and a predetermined outline onto a support protected by a first sheet of material, and the upper surface of the layer and its sides between the lower surface and its upper surface, is also protected with a similar second sheet of material. Then, the protected layer is subjected to vibratory compaction under vacuum and to a hot hardening process in the presence of the catalyst. The two protective sheets are made of resilient material, particularly of natural or synthetic rubber, such as neoprene, and after hardening of the sheets, the sheets are removed, by pulling them from the covered and protected surfaces of the resulting slab.
