Abstract of the Disclosure A rubber, radially expansible ring in a tire building drum is provided for gripping the bead of a tire carcass. The ring is radially expansible in a continuous, circumferential channel of the drum. The ring has an outer surface suitably shaped for holding the bead of the tire carcass, and a pair of continuous, circumferential pressure sealing flaps extending in- wardly from both sides of the ring. The flaps are adapted for sealing engagement with adjacent side mem- bers of the circumferential channel, so that the ring may be radially expanded without the use of an inflatable bladder. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
