Abstract

A bladder for use in conjunction with a tire building drum, said bladder having cords extending substantially parallel to the rotational axis of the bladder and including two belt plies of square woven fabric extending circumferentially about the bladder. The bladder is manufactured by first providing an at least partially cured cylindrical membrane reinforced with cords extending substantially parallel to the rotational axis of the membrane. The membrane is then expanded to a toroidal configuration and an uncured belt structure is applied to the expanded membrane. The membrane is then contracted to the cylindrical configuration and the belt structure is cured.
