ABSTRACT:
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 radial outer peripheral of a bead core (46). The pliers systems are pivoted around an axis spaced from the center of the bead core, with respect to the convergence point of the V-shaped opening formed by the ends of the filler and are angularly moveable upon carrying out their movement, the pliers systems rotate with respect to the other according to an angulation greater than the value of the angle from by the ends of the filler and that the gripping means (25, 26) are shaped in such a way that in a radial outer zone of the filler, the ends are overlapped during the action of the pliers systems. An ancillary pliers system (24) compresses laterally the overlapped ends to effect the final splicing.
