ABSTRACT:
A tire building machine including a building drum for receiving a belt-tread assembly and a pair of coaxial shafts having disc members freely rotatable thereon for receiving and supporting a tire carcass. The disc members and shafts are pivotally movable as a unit and the disc members are also movable with respect to one another for engaging annular beads formed on said carcass to effect a seal therewith and permit the introduction of air to inflate said carcass to assume a toroidal shape. A radially expansible and contractable transfer ring, that is axially movable, engages the belt-tread assembly and transfers same from the drum to the carcass prior to the pivoting of the carcass, belts and tread stock into engagement with a rotatably driven stitcher apparatus.
