Process for the preparation of multilayer blocks suitable for the production of slabs without the use of a sawing machine

Abstract From the Canadian patent

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.
