Abstract
Disclosed is a machine for rotation of the bead area of a green tire so that the bead areas are parallel and concentric in order to remove potential anomalies that can occur to a green tire bead portion during pre-cure handling, storing or during shaping in the tire press. The tire apparatus orients the beads of the green tire parallel and square to one another and also rotates the bead area of the tire into the proper configuration prior to cure. The bead portions of the tire maintain the parallel position as the tire is loaded into a tire mold. Also disclosed is a tire loader that has a bead support ring and paddles to grip the outer crown portion of the tire.
