PROCESS FOR THE PREPARATION OF MULTILAYER BLOCKS SUITABLE FOR THE PRODUCTION OF SLABS WITHOUT THE USE OF A SAWING MACHINE ABSTRACT OF THE DISCLOSURE A process for the production of a multi-layer block by distribution of a mixture, the block being used for the production of agglomerated slabs of marble, granite, sand or in general stone, consists of weighing a predetermined amount of the mixture, mixing it to render it homogeneous, conveying the predetermined amount of homogeneous mixture into a mold provided with a vertically movable bottom, subjecting the mixture to a vibrating action by means of a vibrating plate, then lowering said predetermined amount of the mixture of a distance equal to the thickness of a new slab, covering the mixture with a sheet of impermeable material, repeating the operations until the mold is filled. A multi-layer block is formed, which is compacted and allowed to set. The block is separated into slabs corresponding to the sheets of impermeable material. The apparatus is also described.
