METHOD OF MANUFACTURING SUPPORT BODY FOR PNEUMATIC RUN FLAT TIRE

Title:

METHOD OF MANUFACTURING SUPPORT BODY FOR PNEUMATIC RUN FLAT TIRE

Document Type and Number:

WIPO Patent Application WO/2005/014310

Kind Code:

A1

Abstract:

A method of manufacturing a support body for a pneumatic run flat tire capable of more simplifying a mold and the structure of a vulcanizer. The metal support part (18) comprises three parts formed of a center part (30) and outer parts (32) on both sides thereof. Rubber leg parts (20) are vulcanized/molded to be formed integrally with the outer parts (32) as the parts forming the support part (18). Also, the center part (30) is connected to the outer parts (32) by welding. Accordingly, since the metal mold for vulcanizing/molding the leg parts (20) can be reduced in size less than conventional metal molds, and both right and left leg parts (20) can be vulcanized/molded by one metal mold, the structure of the metal mold can be simplified more than conventional ones.
