Zusammenfassung:	Apparatus and methods of forming a tire. A drum has an expansion device that is configured to turn-up the lateral ends of the tire carcass about respective bead-and-apex assemblies while generally maintaining a constant orientation of the bead-and-apex assemblies. Further, the expansion device turns-up the lateral ends of the tire carcass while at the same time radially expanding the tire carcass. The methods entail turning-up the lateral ends of the tire carcass around the bead-and-apex assemblies and also moving a portion of the tire carcass lying between the bead-and-apex assemblies in a radially-outward direction relative to an axis of rotation of the drum.
