Abstract

Method of manufacturing pointed objects of constant section, by molding, characterized in that the mouldable material is injected into an elongated mold of appropriate section in which a piston can move whose front face is hollowed out by a cavity complementary to that of the tip of the object to be molded, this piston being initially located in the vicinity of the front end of the mold by which the injection is made, then the piston is allowed to retreat until the object has reached the desired length and because a back pressure is exerted on the piston during the injection.
