Abstract

A pneumatic tire carcass building machine has a cylindrical building drum adapted for forming thereon a tire carcass of rubberized cord plies. Bead portions of the tire carcass are made by forming bead ring receiving shoulders in a rubberized fabric ply or plies positioned on said drum at each side of said drum with shoulder forming means, abutting or seating annular bead rings with said bead ring receiving shoulders with bead ring seating or carrier means positioning and holding the bead rings concentrically with bead lock means, and wrapping edge portions of the ply around the bead rings with turnover means while maintaining the concentric position of the bead rings with the bead lock means. Preferably each bead lock means includes at least three bead clamps spaced radially about the shaft of the cylindrical drum in preferably symmetric array, which clamps are driven from preset retracted positions to preset extended positions where they concentrically position the bead rings during turnover of edge portions of the carcass ply or plies.
