(57) The invention relates to a machine for cutting slabs from a stone block (B) by means
of at least one endless diamond belt (7), which extends in the cutting plane around
a belt guiding arm (14) and is returned about pulleys (6) disposed at the ends of
said arm (14), while being slidably guided in grooved guide means (17), which are
provided on the longitudinal edges of the arm. According to a characteristic of the
invention, at least along the inactive return branch of the diamond belt (7), anti-slippage
means are provided, e.g. consisting of wheels (23) arranged over said branch of the
diamond belt (7) in such a manner as to prevent it to come off its respective groove/s
(17) of the guide means on the belt-guiding arm (14). Moreover, the machine may be
mounted on rails or anyway run along a predetermined path transversely to the cutting
plane, so that one or more aligned blocks are still and the cutting plane is moved
along them by moving the machine.
