    摘要: A method for molding a tire tread element by injecting a rubber mixture through injection holes of an injection mold formed by moving two cooperating mold elements toward a cylindrical drum disposed therebetween. The mold elements sealingly match to an outer surface of the inflatable drum to define a mold cavity of a cross-section and length selected to form a tread element of precisely defined shape and size. A breaker layer may be integrated with an injected rubber mixture and the tread element may be made to be completely circular or linear with matchingly formed end surfaces enabling secure adherence thereat.
