Abstract
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.
