Abstract

A tire building machine that allows for free axial movement of positioned beads towards a tire drum during expansion of the tire drum. The axial movement of the bead is effected by a rubber sleeve that envelops the tire drum and a pair of bead carrier assemblies, each one located axially outwardly of the drum. Subsequent to positioning the bead in a tire building process, the beads are locked into place by means attached to each of the bead carrier assemblies. Expansion of the drum causes the sleeve to effect inwardly axial movement of the bead carrier assemblies toward the drum carrying the tire beads towards the drum, and retraction of the drum causes outwardly axial movement of the bead carrier assemblies away from the drum.
