<p>The described device comprises two primary pliers systems (2, 2a) arranged to engage through respective gripping elements (25, 26) the opposite ends of an elastomeric filler (45) applied on the bead core (46). The pliers systems are pivoted around an axis a little far, toward the center of the bead core, with respect to the convergence point of the V-shaped opening formed by the ends of the fillers and are angularly mobile to draw near and to splice the ends themselves. It is provided that on carrying out their movement, the pliers systems rotate the one with respect to the other according to an angulation greater than the value of the angle formed by the ends of the filler and that the gripping means (25, 26) are shaped in such a way that in a circumferential outer zone of the filler, the ends are oriented according to offset planes to mutually get near during the action of the pliers systems. An ancillary pliers system (24) compresses laterally the approached ends to effect the final splicing.</p> |
