Abstract

A tire-building machine is a structural combination of two relatively independent sections. Each section comprises a support housing, a rotatable shaft cantilevered from the housing and a cylindrical drum mounted at the free end of the shaft for rotation therewith. With the axes of the shafts aligned, the drums thereon are connectable at their outer axial ends to form a divisible tire-building drum of predetermined axial length or "set." An annular ply turnup bladder is mounted for rotation with each shaft adjacent the inner axial end of each drum. Also, an annular bead ring carrier is mounted on each housing to reciprocate coaxially of each shaft. The set of the divisible drum can be adjusted by replacing one or both of the constituent drums with other drums of different lengths.
