Abstract: A tire building machine, comprising a radially expansible and contractable, breaker-tread assembly building drum having a magnetized outer surface for retaining building alignment of metallic cord breaker plies during building of the assembly, a pair of variably spaced tire carcass support and shaping discs coaxial with but spaced from the building drum and providing for direct inflation of a first stage carcass supported thereon, a radially expansible and contractable and axially movable transfer ring for transferring breaker-tread assemblies from the drum to carcasses on the shaping discs, and movable, conical, shaping rings engageable with the outer sidewalls of the carcass during expansion of the same for limiting such expansion to a symmetrically centered pattern with respect to the breaker-tread assembly and the beads of the carcass. The foregoing abstract is neither intended to define the invention disclosed in this specification, nor is it intended to be limiting as to the scope of the invention in any way.

Abstract: A radially expansible and axially contractable single-stage tire building drum, especially suited for building tire carcasses of high stiffness ply material having metallic wire cords or cables incorporated therein, is disclosed. The drum has two axially spaced, radially split cylindrical drum end sections arranged for opposed joint axial movements and each composed of rigid, circumferentially aligned, cylindrical sector-shaped elements, and an elastically radially expansible tubular diaphragm surrounding the space between the drum members and circumferentially secured to the latter at its ends. In the radially smallest and axially largest condition of the drum, the two drum end sections and the diaphragm, the latter at that time being internally rigidly supported by an internal lever system linking the drum end sections to one another, define a minimum diameter continuous cylindrical surface for receiving the carcass ply material and enabling the bead cores to be loosely slipped thereonto. Mechanical camming means including screw-actuated rollers operatively engaging the sector-shaped elements are provided for forcing the same radially outwardly under high unyielding forces to cause the carcass ply material to be tightly clamped against the surrounding bead cores, which minimizes the possibility of slippage of the ply material relative to the bead cores during the ply turn-up operation and during the subsequent shaping operation as the carcass is inflated and expanded radially outwardly while the drum end sections are displaced axially inwardly of the drum. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
