Abstract

Constructive disposition of peak of rafado of minerals, with a piece of body provided with a cutting tip formed in an extremity of the mentioned piece, characterized because the dimension of greater width of the peak of rafado, in the direction of the movement of advance of the peak of rafado adjacent to the cutting tip, is greater than the corresponding dimension of a peak peak mount, or beak holder, on which, in operation, said body part of the beak peak is mounted, this piece being of shaped body, at said extremity, as an upper part that extends backwards from the body part and because the rear surface of said upper part extends, from the lower face of said upper piece, according to an angle that diverges from the perpendicular to the lower face of said upper piece.
