Abstract
Abstract Tire building method and apparatus especially adapted for single stage building of ''''belted'''' pneumatic tires, using a drum assembly providing a rigid cylindrical surface for the building thereon of a flat, cylindrical tire body or carcass by the application to the drum of one or more radial or bias cord inner body or carcass plies and which drum is expansible for assembly and setting with the inner body or carcass of the inextensible tire beads or bead rings, and is further expansible and otherwise movable to impart to the body or carcass the desired size and shape for the reception of the circumferentially inextensible breaker strip or strips which form the ''''belt'''' and the tire tread material. The drum assembly includes three axially adjacent, mechanically expansible, sections the center section being expansible to a substantially greater extent than the end sections and the end sections being movable axially toward one another when the center section is expanded beyond the end sections to maintain the transverse perimetric dimension of the drum assembly constant or substantially so. The center drum section includes replaceable or interchangeable interleaved peripheral segments that are moved in a positive manner transversely of the drum axis to form a rigid expansible surface. A flexible cover, expansible peripherally, overlies the center drum section and is secured to the end drum sections. Pivotable members, circumferentially adjacent each other and carried by the end drum sections, underly the periphery of the flexible peripherally expansible cover on opposite sides of the center drum section and provide rigidity the full length of the drum assembly.
