Description

ABSTRACT OF THE DISCLOSURE A tire curing press and method are characterized by a center mechanism operative first to center the top bead of a green tire carcass with respect to the top mold section and then the bottom bead with respect to the bottom mold section, and to hold the beads centered and axially separated as the press closes to cause the beads to register and seat with the toe rings of the top and bottom mold sections simultaneously as the press closely approaches its closed condition. The center mechanism comprises top and bottom segmented annular clamping rings adapted to engage and shape the axial interior of the bead area of the tire and respective chuck assemblies including a multi-faceted linear cam and respective followers for each ring segment operative to collapse each alternate ring segment and then each other ring segment. The clamping rings achieve automatic loading, centering and unloading and may be used individually or paired in bladder or bladderless curing.
