Wire sawing device

Wire sawing device comprising wire guide cylinders (1 to 4) supporting a wire (5) maintained in position by grooves provided on the surface of the wire guide cylinders, which define the interval between the wires of at least one layer (6) of wires, the wire being adapted to move with reciprocal or continuous movement while bearing against at least one piece (10) to be sawed, characterized by the fact that it comprises two external wire guide cylinders (1, 2) and two internal wire guide cylinders (3, 4) disposed between the external wire guide cylinders, whose diameter is smaller than that of the internal wire guide cylinders, and by the fact that the external wire guide cylinders (1, 2) are driven in rotation by motor means to cause the movement of the wires of the layers of wires, whilst the internal wire guide cylinders (3, 4) ensure the function of guidance without driving the wires of the layer of wires, the wire being spirally wound about the assembly of wire guide cylinders without the layers crossing.
