<p>A method for surface working of items made of stone materials or the like, using abrasive-free liquid jets, comprises the steps of (a) providing a moving or stationary support base (2) for the items (P), (b) providing a plurality of nozzles (4, 4', 4', ...) for generating jets (J) oriented toward the items (P), (c) feeding the nozzles (4, 4', 4', ...) with a high-pressure liquid adapted to create cuts on the items (P) being worked, (d) forwardly moving the items (P) relative to the nozzles (4, 4', 4', ...) in a longitudinal direction (X), (e) staggering the relative positions of the nozzles (4, 4', 4', ...) in a transverse direction (Y) with a predetermined pitch (p), for continuous adjustment of the projection of their pitch (p) on a vertical plane (71) substantially parallel to the transverse direction (Y), to change the transverse distance (d) between the longitudinal cuts made by the jets (J).
