DEVICE FOR THE AUTOMATIC AND CONTINUOUS CORRECTION OF THE CENTRES OF OSCILLATION IN A PENDULANT FRAME FOR THE CUTTING OF MARBLES, GRANITES AND HARD STONES

摘要

ABSTRACTIn a pendulant frame with multiple blades formarbles, granites and hard stones, it is provided that thecentres of rotation (1 and 2) of the connecting rods (3 and4), which support the blade carrier (5) of the saw, are movedduring the cutting operation jointly by the eccentric discs (6and 7), for the purpose of compensating, in the variousoperating positions, the displacement of the base (8) of theconnecting member (9) which together with the flywheel (10)controls the alternating movement of the blade carrier (5), soas to permit a perfect symmetry of the pendulant motion of thesame with respect to the vertical axis (Figure 1).rn/
