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. The cross beam is associated with a drive means for moving the cross beam in a vertical direction and in a direction transverse of the row of the presses, the cross beam carrying followers adapted for cooperation with vertical grooves in the side jaws mounted on the carriages, whereby the cross beam is vertically movable relative to the carriage and independently therefrom, the carriage moving jointly with the cross beam, as the latter moves transversely of the row of the presses.
