摘要：A method and apparatus for manufacturing an annular tire component such as a
tire bead includes locating a toroidal support (12); placing an ejector nozzle (32) in an interference relationship to the toroidal support (12); and simultaneously ejecting through the nozzle (32) a continuous stream of an elastomeric belt component material (52) in a suitably fluid state and a continuous length of at least one thread-like component (44) dispod within the stream onto the toroidal support (12) in a predetermined bead configuration. The bead configuration is at least partially defined by a relief in the nozzle ejection port and by the toroidal support onto which the bead is formed. Rotation of the toroidal support (12) may be coupled with the simultaneous ejection of the elastomeric component (52) and thread-like component (44) in order to create an annular bead structure. A tire may be constructed having a desired bead configuration and location by means of the method and apparatus.
