ABSTRACT:
A green tire inserting apparatus with which upper and lower bead portions of a green tire can be inserted correctly and surely into bead rings of upper and lower metal molds. An upper bead portion and a lower bead portion of a green tire are gripped in a true-circular shape by separate segments to be pushed respectively into bead rings of upper and lower metal molds in a vulcanizing machine. Cylinders and linkages for radially expanding the segments and pushing the bead portions into the bead rings are provided in an upper portion and a lower portion of a center mechanism of a vulcanizing machine. There are provided stoppers for presetting a segment expansion limit, which are adjustable according to variation of a bead diameter of a green tire, and bead height regulators, which are adjustable according to variation of a height of a green tire. The adjustment can be made to be automatic.
