Abstract
A machine for cutting blocks of natural or similar types of stone includes a plurality of diamond-wire loops, wound about an assembly for the support and transmission of the cutting motion to said diamond-wire loops and at least one assembly for supporting, tensioning and guiding the diamond-wire loops; said assemblies move vertically in unison on the structure of the machine; and presents said supporting, tensioning and guiding assembly comprising a set of pulleys for the support and return of each diamond-wire loop, which are mounted and registered, for wire tensioning, on a movable tensioning means whose registration movement is actuated by a tensioning control means, independently of the movable tensioning means of contiguous diamond wires. In its preferred embodiment, the machine also presents an assembly for the support and transmission of the cutting motion to the said diamond-wire loops which includes a wide-diameter wheel about which a belt is wound that is provided with races for housing the diamond-wire loops and which is tensioned by means of a tensioning wheel.
