| 20110142977 | Extended Life Tire Curing Bladder Composed of Aramid Fibers - Disclosed is a mixture to create expandable curing bladders for use in the curing process of rubber compositions such as tires. The bladders have an increased service with the addition of the aramid fibers to the rubber polymer. The aramid fibers increase the tear resistance of the cured product allowing for an increased number of expansions and contractions of the rubber polymer during the curing process. The use of these aramid fibers allows the tire curing bladders to cure more tires without changing out the bladder increasing the cost efficiency of the tire curing bladder. | 06-16-2011 |
| 20110262573 | METHOD FOR MANUFACTURING BLADDER FOR USE IN MANUFACTURING TIRES - A method for manufacturing a bladder for use in manufacturing tires having a surface-modified rubber layer on an outer surface side of a base rubber layer, including the steps of: forming an uncross-linked body of the surface-modified rubber layer by molding a rubber composition including a modified butyl rubber composition and an organic peroxide and applying a siloxane compound having a (meth)acryloyl group to a surface of this rubber molded body; forming the base rubber layer from an unvulcanized body or vulcanized body formed from a rubber composition different than the modified butyl rubber composition; laminating the uncross-linked body of the surface-modified rubber layer on the outer surface side of the base rubber layer; and heat treating. | 10-27-2011 |
| 20130129850 | SURFACE TREATMENT OF RUBBER USING LOW PRESSURE PLASMA - A method of treating a surface of an object comprising a rubber material and in particular a bladder for use in a process for making a vehicle tyre. The method comprises subjecting the surface to a gas at a low pressure at which the gas is susceptible of forming plasma, and causing the gas to form plasma. In order to obtain repellent properties of the surface of the rubber material fluorine gas such as tetrafluormethane or hexafluorethane is used. Preferably the treatment is performed until there is obtained a surface layer of the rubber material with properties modified by the treatment having an expected lifetime corresponding to the expected lifetime of the object. | 05-23-2013 |

| 20100015265 | PRESSURE BLADDER AND METHOD FOR FABRICATION - A pressure bladder has a seamless shell made from an elastomeric material, an inner cavity, and a pressure port. The bladder can also have a reinforcement layer and an outer layer to reinforce the bladder and define the bladder's outer dimensions and pressure profile. In order to fabricate the bladder, a mandrel is formed, and the pressure port is positioned on the surface of the mandrel. The mandrel is then coated with the elastomeric material and placed in a mold. A reinforcement layer is added and an elastomeric material is injected into the mold to form the outer layer. The mandrel is then removed from the mandrel assembly by applying heat and pressure to the bladder such that the mandrel can be extracted through the pressure port. | 01-21-2010 |

| 20150030711 | RIGID CORE FOR FORMING TIRE - Provided is a rigid core for forming a tire, configured so that the intrusion of rubber into a gap between core segments is prevented and so that the lowering of roundness of a core body s prevented. The core body comprises a plurality of circumferentially divided core segments. Both circumferential end surfaces of each of the core segments are used as mating surfaces , and the mating surfaces adjacent to each other in the circumferential direction are abutted against each other to form the core body. At least one of the mating surfaces adjacent to each other in the circumferential direction is formed as a stepped mating surface comprising a bordering surface region extending along an outer circumferential edge of the mating surface, and a recessed surface region surrounded by the bordering surface region and recessed in a step shape from the bordering surface region so that only the bordering surface region contacts with the adjacent mating surface. | 01-29-2015 |
