Device for applying the elastomeric filler to the bead core of a tire

DETAILED DESCRIPTION What is claimed is: 1.
Device for applying an elastomeric filler on the bead core of a tire, consisting of two discs with a common axis of rotation, which can be moved away from each other or brought together respectively to receive the bead core before the application of the filler and to unload the bead core with the filler and to form an annular seat designed to accommodate the bead core, the said device being characterised by the fact that it includes means for automatically loading the bead core from a first position to a second position in which the bead core is between the two discs with its center aligned with the common axis of rotation, the said means having two jaws and means for controlling the opening of the jaws, the said two jaws rotating in relation to each other round a first hinge arranged on a suitable support rotating around a second hinge in order to bring the jaws from the first of the said positions to the second and vice versa, the said two hinges having axis of rotation parallel to the common axis of rotation of the two discs, the profile of the jaws when closed having surfaces corresponding to circle arcs of the radial profile of the bead core, the said surfaces of the jaws being provided with means for connecting to the corresponding parts of the radially outermost periphery of the bead core, the said means for controlling the opening of the jaws being actuated when the bead core had already been locked in the annular seat between the two discs and the support is moved from the second of these positions to the first, and said means for controlling the opening of the jaws having an element for controlling the rotation of the first jaw, the path of which from the second of these positions to the first meets the external profile of the bead core, the said first jaw rotating around the first hinge and in relation to the second jaw kept stationary on the said support.
2.
Device in accordance with claim 1, characterised by the fact that the profile of the jaws is subdivided into at least three circle arcs of the bead core, having, from the start to the end of the three arcs, an angle at the center of less than or at the most equal to 180
