A concrete stone texturing machine, method and a stone having an irregular rough surface resembling a real stone face is described. The machine conveys concrete stones having opposed flat surfaces to a pitching station having at least one pair of opposed pitching blade assembles aligned in a common plane on a respective side of the pitching station. The pitching blade assemblies are displaced towards and away from one another a predetermined distance. Each assembly has a plurality of pitching blades secured in side-by- side aligned relationship. Each of the pitching blades has a forward projecting cutting edge and a securing body portion. A first group of the pitching blades has their cutting edges aligned along a first straight cutting axis which is offset from the cutting edges of the second group of pitching blades aligned along a second straight cutting axis. The cutting axes are parallel to one another. With the offset cutting edges a unique appearance of the pitched blocks surface is obtained when the pitching blades are forced to penetrate a predetermined distance in an associated one of the surrounding transverse faces of the block adjacent a surface to be pitched.

Machine et procédé de texturation des pierres en béton. La machine transporte des pierres en béton présentant des surfaces plates opposées vers un poste de taille comportant au moins une paire de lames de taille opposées et alignées sur un plan commun sur un des côtés du poste de taille. Les lames de taille se rapprochent et s'éloignent l'une de l'autre sur une distance prédéterminée. Chaque lame de taille comporte une arête de coupe dirigée vers l'avant et un élément de fixation. Un premier groupe de lames de taille comporte des arêtes de coupe alignées sur un premier axe de coupe droit qui est décalé par rapport aux arêtes de coupe du deuxième groupe de lames, lesquelles sont alignées sur un deuxième axe de coupe droit. Le décalage des arêtes de coupe permet de conférer un aspect unique à la surface des blocs.
