(54) An apparatus for continuously feeding powders in manufacturing of ceramic tiles


(57) An apparatus for continuously feeding powders in manufacturing of ceramic tiles, which powders form a layer (200) of coloured powders upon a continuously advancing base layer (100), the layer (200) being fed by a prism-shaped hopper (4) containing many-coloured powders in a pre-ordered arrangement. The appartus comprises means for creating troughs in the base layer (100) before the base layer (100) receives the layer (200) of coloured powders. The means comprise a screed (10) of the base layer (100), comprising a sheet (110) of plastic or elastomer material, a powder-contacting edge of the screed (10) exhibiting a non-rectilinear outline which is continuously modifiable in a vertical plane.
