Automatic saw, characterized because it imports a vertical piston block with hydraulic drive of the bearing-saws arc, between two of which effect the driving of a continuous flow a hydraulic cylinder that drives the tilting continuous advance and interrupted the saw blade while pus another of the pistons synchronized to the previous ones through a unidirectional duct suction of the cylinder me caudal that the one that feed the aforementioned pistons leaves the free one by the solo of the arc porta saws from the final position of advance to enable the retreat in elliptical movement of the arc without tripping the material, and then through another unidirectional conduit to drive a lower flow to the cylinder than the subtracted from making feasible u-wheel arch part saws in a final position of coincident backward movement in linens: with the final position of the advance, previous in the achievement thus of the continuity of the advance.
