<p>1. Method of making grooved mouldings and bulging mouldings, notably for the decoration of buildings and funeral monuments, from parallelepipedic mouldings (16) of great length in stone, such as granite, characterized in that the method consists of making a longitudinal hole of the desired diameter in said moulding (16) by means of a bell saw with horizontal axis, in such a way as to obtain, on the one hand, a core (18) of desired diameter and, on the other hand, a parallelepipedic block (16) provided with an axial bore ; of cutting said core (18) along two perpendicular longitudinal planes in such a way as to obtain four convex mouldings (10, 10', 10", 10"'), and of cutting said block (16) along two perpendicular longitudinal planes in order to obtain four grooved mouldings (12, 12', 12", 12"').</p> |
