<p>The improved multi-blade frame referred to in the invention involves four support devices, created by means of pairs of crossed rods 4 and 5, which connect the rocker arm 3 to the supports 6 and 7, integral, by means of the plate 8, with the blades 9, with the advantage of notably increasing the radius of curvature of the path of the bladeholder during oscillation and, as a consequence, clearly reducing the work times with respect to the yield in the granite block sawing operation (fig. 1). <IMAGE></p> |
