20130056128 | PNEUMATIC TIRE WITH CONDUCTIVE BLEEDER CORDS - A carcass ply for a pneumatic tire in accordance with the present invention includes a plurality of load bearing cords calendered within a polymer matrix and a plurality of gas bleeder cords for moving gas away from an interface of the load bearing cords and the polymer matrix. The plurality of gas bleeder cords also function to conduct electrical charge from a belt structure of the pneumatic tire to a bead portion of the pneumatic tire. | 03-07-2013 |
20130075017 | METHOD FOR FORMING STRATIFIED RUBBER ARTICLE - A method and apparatus for applying a blended rubber composition directly onto a tire building drum or core is described. The method includes the steps of extruding a first rubber compound through a main extruder and a main gear pump. A second rubber compound is extruded through a second extruder and into a second gear pump. The output from the second gear pump is fed into the main extruder. The ratio of the first compound to the second compound is varied by adjusting the speed of the main gear pump and the speed of the second gear pump. A continuous strip of rubber formed of said first compound and said second compound is layed directly onto a tire building machine to form a first layer of rubber having a first blend ratio. The speed of the main gear pump and the second gear pump is adjusted to obtain a second blend ratio of said first compound to said second compound, and then a strip of rubber formed of said second blend ratio is applied to the tire building drum or core. | 03-28-2013 |
20130160912 | RUBBER COMPOSITION AND RUNFLAT TIRE - The present invention is directed to a rubber composition comprising: a functionalized elastomer comprising a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; and a functional group bonded to the backbone chain, the functional group comprising a multidentate ligand capable of complexing with a metal ion; and an encapsulated metal salt. | 06-27-2013 |
20140148555 | SELF-HEALING RUBBER COMPOSITION AND TIRE - The present invention is directed to a self-healing rubber composition comprising a functionalized elastomer comprising: a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; and a functional group bonded to the backbone chain, the functional group comprising a multidentate ligand capable of complexing with a metal ion; and a partitioned metal ion. | 05-29-2014 |
