Sawing machine

An automatic sawing machine (1) for cutting blocks of natural and/or concrete stone material, wherein said machine (1) comprises:

• a single motorized conveyor belt (2), which defines a cutting path suitable for receiving in succession said blocks of material to be cut and to transport them from a first inlet station (7) to a second outlet station (6);
• and
• a plurality of cutting devices (8) each of them being provided with a motor (8a) on whose axis a circular blade (10) is keyed, said cutting devices (8) being constrained to said machine (1) and being arranged above the cutting path defined by the conveyor belt (2) with respect to a vertical direction so that the respective circular blades (10) are inside the cutting path itself;
• wherein said single motorized conveyor belt (2) comprises a conveyor plane (3) for transporting the material to be cut and a driving wall (4) that all together contribute to give the single conveyor belt (2) a substantially “L”-shape, and a series of modular strips (5) placed adjacent one to the other, wherein each of said modular strips (5) is a single element having itself an L-shape constituted by a first portion (5a) and a second portion (5b) placed substantially at 90° with respect to said first portion (5a), and wherein the series of said first portions (5a) of the strips (5), side by side, constitute said conveyor belt (3) and wherein the series of said second portions (5b) of the strips (5), side by side, constitute said driving wall (4);
• wherein each of said second portions (5b) of said strips (5) is provided with a slot (12);
• the machine (1) further comprising a support (14) fixed to the machine and a rotatable crown element (15), placed at the top of said support (14), provided of a plurality of protuberances (16) spaced apart from each other so as to allow each of said protuberances (16) to be inserted in turn into one of said slot (12) obtained in one of said second portions (5b) of said strips (5), following the movement of the conveyor belt (2).
