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.

Abstract: The pneumatic tire vulcanizing apparatus includes a series of vulcanizing presses arranged in a row, the presses including mold assemblies each having a top mold section and a bottom mold section, and a manipulator for reloading of the molds. The manipulator includes a frame associated with drive means for moving the frame along the row of the presses, the frame supporting thereon a mold opening mechanism including a cross beam provided with clamping means adapted to engage the top mold sections, as well as a mechanism for loading green tires into bottom mold sections, associated with a carriage supporting green tire holders.
