<p>A machine for multiple wire cutting of stone materials comprises a plurality of cutting devices (4) mounted on a supporting structure (3), the devices arranged parallel and drawn near to each other, each device in turn comprising a cutting wire (17) extending along an annular extension trajectory around driving means (18) and around at least one return pulley (19). The supporting structure (3) comprises one or more supporting arms (21 ) on each of which the return pulley (19) of at least one cutting device (4) is mounted. Each first supporting arm (21 ) can also be at least selectively moved relative to the rest of the supporting structure (3) between an operating position, in which the return pulley (19), (20) mounted on it is at least mainly facing other parts of the machine (1 ) which prevent it from being mounted and/or removed, and a maintenance position, in which the return pulley (19), (20) mounted on it is at least mainly not directly facing other parts of the machine (1 ), thus allowing an operator free access to it in Order to remove it from and/or mount it on the arm (21 ), (22).</p> |
