ABSTRACT:
The green tire holder disclosed herein comprises a vertical shaft having a plurality of uniformly spaced apart arms extending outwardly therefrom, a slidable shoe mounted on each of said arms for engaging a bead of a green tire and a slidable tread support mechanism mounted on each arm near the outer end thereof. The tire holder includes means for moving all of the shoes simultaneously toward or away from the center by equal amounts, so that the shoes at all times are equidistant from the center. Each tread support mechanism includes, a tiltable support plate, preferably flat, which engages the tread portion of the green tire, and a support arm for supporting the plate. The tread support mechanisms are slidable independently of the shoes. The angle of inclination of the tread support plates may be varied, e.g. from 0.degree. to 60.degree. to the horizontal at 15.degree. intervals.
