ABSTRACT:
In the two-stage manufacture of radial ply tires, the sidewall stock is applied to the cylindrical tire body on a mandrel so as to overlie the turned over ply ends and extend beyond them, and while the mandrel is stationary, the sidewalls are bonded to the underlying plies by inflating bladder assemblies so as to cause them to press the sidewall stock against the underlying plies.
