ABSTRACT
In a pendulant frame with multiple blades for
marbles, granites and hard stones, it is provided that the
centres of rotation (1 and 2) of the connecting rods (3 and
4), which support the blade carrier (5) of the saw, are moved
during the cutting operation jointly by the eccentric discs (6
and 7), for the purpose of compensating, in the various
operating positions, the displacement of the base (8) of the
connecting member (9) which together with the flywheel (10)
controls the alternating movement of the blade carrier (5), so
as to permit a perfect symmetry of the pendulant motion of the
same with respect to the vertical axis (Figure 1).
