ABSTRACT:
The apparatus is so constructed that the manipulator thereof, successively positionable over a series of tire vulcanizing presses, has mounted directly thereon a plunger that can be lowered vertically to push the bladder into the well in the bottom mold section of the press and to spread radially the segments clamping the bead of a cured tire. The same manipulator supports the rod of a mechanism for removing cured tires, movable vertically upward in opposition to the plunger.
Each bladder is provided at the center thereof with a ball valve closing off the hole for the plunger after the exit of the plunger therefrom, the latter being actuated by a rack-and-pinion transmission preventing rotation of the plunger.
