SAWING MACHINE FOR DIVIDING BLOCKS OF STONE MATERIAL INTO SLABS

摘要

In the sawing machine, "cutting wires" are each wound in a closed loop and run between a driving pulley and a driven pulley. The distance between adjacent cutting wires and, therefore, the thickness of the slabs cut by the said wires is defined. The sawing machine, according to the invention, includes a guide pulley (10) with a plurality of external circumferential grooves (13) which are separated from each other at a pitch or constant distance (p) that is approximately equal to a standard reference unit of measurement or fraction thereof for the thickness of the slabs that are to be cut. Each cutting wire (20) is guided in its own groove selected from among the said grooves (13) of the guide pulley (10), in such a way that the thickness(s) of the finished slab cut by two adjacent cutting wires (20) is approximately equal to the pitch (p) multiplied by the number (n-2) of unoccupied grooves (13) of the guide pulley (10) between the said two adjacent cutting wires (20) performing the cutting.
