Claim 8:
9. 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 an article to be manufactured;
b) a first mixture comprising inorganic particles and an unhardened binder is discharged onto the template, such that said first mixture rests on the surface and fills at least a portion of the template's gaps;
b1) the first mixture is compacted, forming a compacted layer of the first mixture within the template's gaps;
c) the template is removed, leaving cavities within the compacted layer of the first mixture, the cavities being defined by the positions of the islands of the template; and
d) a second dispensing distributor device dispenses a second mixture comprising at least 50% by weight of the total mixture of inorganic particles and an unhardened binder into the cavities in the compacted layer of the first mixture,
wherein the second distributor device moves along at least a portion of the cavities when dispensing the second mixture therein;
wherein the second distributor device comprises a conveyor belt for transporting the second mixture,
wherein the second distributor device is assembled on a robotic device that moves it along at least a portion of the cavities, and
wherein, when dispensing the second mixture, a computer system controls and/or synchronizes the speed of the conveyor belt, the speed of the robotic device, and the position of the robotic device.
