Method and System for Producing Slabs, Tiles or Sheets of Artificial Stone with a Wide Vein Effect

A method for manufacturing slabs, tiles or sheets of artificial stone with a wide vein effect, which comprises the following steps:

• a) a template is positioned on a surface, the template comprising gaps and islands, wherein the islands correspond to at least one vein of the article to be manufactured;
• b) a first mixture is discharged, which comprises inorganic particles and an unhardened binder, onto the template, by means of a first distributor device, such that said first mixture rests on the surface and fills at least a portion of the gaps of the template;
• c) the template is removed, obtaining a layer of the first mixture with cavities in said layer, defined by the positions of the islands of the template;
• d) a second mixture is discharged, which comprises inorganic particles and an unhardened binder, in order to fill at least a portion of the cavities in the layer of the first mixture with said second mixture;
• e) the resulting layer of the combination of first and second mixtures is compacted, and a hardening process is carried out, in order to obtain the slab, tile or sheet of artificial stone with a vein effect;
• characterised in that in step d) said second mixture is discharged in a localised manner on the cavities in the layer of the first mixture, by means of a second distributor device, which comprises a collector, the bottom opening of which has, in at least one direction, a width less than or equal to the maximum width of the cavities, said second device moving along at least a portion of the cavities, filling at least partially a portion of said cavities with the second mixture.
