The sawing machine according to the invention comprises a double portal structure (11) with two pairs of uprights (11.1), along which slides a respective ram (13). The rams (13) bear four support shafts (15), superposed in pairs and each supporting a coaxial roller, respectively a plurality of coaxial pulleys (18), mutually juxtaposed in packet fashion, having coplanar races according to respective vertical planes. A shaft (15) rotates integrally with the respective roller, or with the respective packet of pulleys (18). The other rollers, or packets of pulleys (18) are idle. On sets of four coplanar races is wound a corresponding wire or cutting tool (19) in closed loop, to execute the cut in a corresponding vertical plane of a block of material (B). |
