Abstract
An inflatable bladder for a tire building drum is adapted for mounting snugly on a cylindrical drum extension which has a circumferential groove accommodating a non-inflatable elastic ring secured integrally to the bladder. The bladder inner wall has a flangeless port between two circumferential sealing ribs integral with the bladder wall. The port is in air-flow communication with a channel in the outer surface of the extension.
