ABSTRACT:
In a green tire charging apparatus for a tire vulcanizing machine according to the present invention, provision is made such that a vertically movable chuck body is inserted into a tire, chuck segments which are synchronously slidable in the radial direction are expanded to concentrically hold an upper bead portion by upper projections of centering rods, the chuck body is raised to insert the upper bead portion into an upper bead ring of a metal mold, subsequently the upper bead portion is held by holder arms of holders, the chuck body is lowered to hold a lower bead portion of the tire by lower projections of the centering rods, and the lower bead portion is inserted into a lower bead ring of the metal mold. Owing to the above-mentioned the upper and lower bead portion of provision, even a deformed green tire can be surely set on the upper and lower bead rings, respectively, of the metal mold.
