Means for positioning an assembled bead for a tire which bead includes an inextensible bead core and an apex of an uncured curable rubbery compound which is easily deformed. The assembled bead is first located concentrically of the axis and in a plane perpendicular to the axis of a tire building drum. The bead is then carried from its first location, supported only by the apex, to axial registry around a bead-setting groove of a tire building drum. The groove is expanded radially to conform a tire carcass band to the bead. The bead, being free of supporting devices within, is seated accurately in the carcass overlying the grooves. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description. |
