Abstract
A tire curing press which includes a center mechanism projecting from the bottom mold section, such center mechanism including a top movable clamping plate supporting the open upper end of a shaping bladder, and a chuck in the top mold section interfitting between the bead ring on the top mold section and the top plate on the center mechanism, when the press is closed, the chuck including toe portion adapted to fit under the bead of the cured tire, a conical skirt portion centering the I.D. of the tire bead shortly after the press begins to open, and a heel portion adapted to bear against the bladder as the chuck opens. The cured tire is then under the control of the chuck and is maintained centered as the tire is stripped from the mold sections and the bladder from the tire. The bladder may be stripped from the tire by vertically elongating the bladder with the chuck remaining in contact with the top plate. When the shaping bladder is clear of the tire, the chuck is elevated to lift the cured tire to clear the projecting center mechanism as the press head and top mold section move rearwardly. When fully opened, the chuck extends to place the tire on a tire receiver or take-away conveyor when the chuck collapses. In this manner, the tire is always centered and significant dropping or uncontrolled free movement of the tire is avoided.
