Apparatuses for applying elastomeric fillers to tire bead-cores

An automatic apparatus for assembling an elastomeric filler with a vehicle tire bead-core comprising a frame, and associated with the frame at least one drum rotating around its own axis adapted to provide a seat for a bead-core, a disc having an axis of rotation substantially parallel to the axis of the drum for initiating rotation of the drum with the relative periphery and for assembling the filler with the bead-core, means for butt-splicing the ends of the filler together, and means for loading the bead-core, said apparatus being characterized by the fact of comprising, first means for orienting and maintaining the filler assembled with the bead-core before it is discharged substantially on the drum midline, second means for discharging the bead-core with the orientation of the filler determined by the first means, unchanged, said first means comprising a plurality of bodies having contoured surfaces with a sliding characteristic corresponding to that of a metal in contact with the elastomeric material of the filler, said bodies being assembled to idle on its own small shaft of rotation associated with a support of the frame with an arrangement originating an undulated path through which passes the filler associated to the drum in rotation around its own axis thereby stretching the filler and opposing elastic return and bending with respect to the drum midline, said second means comprising, a discharging device at localized action on the opposite sides of the filler with relative advancing mechanism of said device in the plane of the drum midline.
