|20150251368||METHOD FOR APPLYING TO THE INNER WALL OF A TIRE - A process for applying particles to the inner wall of a tire comprising two sidewalls, a crown provided radially externally with a tread, a carcass-type reinforcing structure and at least one crown reinforcement, the inner surface of the sidewalls and of the crown forming an inner wall, at least one portion of said inner wall being covered with at least one layer of self-sealing composition.||09-10-2015|
|20150251367||MOLD ELEMENT FOR VULCANIZING A TIRE TREAD - A mold element for vulcanizing all or part of a tire tread intended to accept studs for driving on ice. The mold element comprises a molding surface able to mold all or part of the tread surface of this tread. The mold element comprises an insert added into the mold element. The insert comprises an insert body intended to be fixed into the mold element, a rod intended for molding into the tread a cavity that is capable of accepting a stud, this rod being fixed removably to the insert body, marking means able to mold a pattern on the tread near the stud. The marking means are fixed removably to the insert body by fixing means.||09-10-2015|

|20150246587||TIRE COMPRISING A HIGH CONTRAST PATTERN COMPRISING A PLURALITY OF CAVITIES - A tire made of rubbery material comprising a sidewall and a pattern formed on this sidewall. This pattern comprises a plurality of openings and intermediate zones separating these openings. In order for the pattern to contrast with the sidewall, the openings occupy at least 60% of the pattern, these openings being distributed through the pattern at a density at least equal to five openings per square millimetre (mm||09-03-2015|
|20150246586||TREAD FOR PNEUMATIC TIRE - A pneumatic tire tread that maintains a good level of water drainage performance up to the final stage of wear of a tread part formed with a plurality of flexible fences which are disposed inside at least one main groove extending from the bottom surface of the main groove and obstructing at least 70% of the cross-sectional area of the main groove, the flexible fences comprising an inside portion having a connecting part which is connected to the main groove, and an outside portion which is radially outside a predetermined height D||09-03-2015|
|20150240059||Method of Producing Rubber Compositions with Reinforcing Resins - Methods for producing a rubber composition for a tire component that include preparing a methylene acceptor block by mixing a first highly unsaturated diene elastomer with a methylene acceptor. This mixture is then cooled and may then be used or may be stored for later use in producing a rubber composition. Such methods may further include mixing a non- productive mix, the non-productive mix comprising a second highly unsaturated diene elastomer, a reinforcing filler and the methylene acceptor block. The methylene acceptor block itself comprises no or essentially no reinforcing filler. To prepare for the addition of the vulcanization agent, such methods, include cooling the non-productive mix and then mixing a vulcanizing agent and a methylene donor into the cooled non-productive mix to produce a productive mix.||08-27-2015|
|20150239301||TYRE DESIGNED TO BE ABLE TO RUN FLAT, COMPRISING A HYBRID CARCASS PLY - A tyre, which is designed to be able to run flat, includes a carcass reinforcement. The carcass reinforcement includes at least one reinforcing element. Each reinforcing element includes at least one multifilament plied strand made of aramid and at least one multifilament plied strand made of polyester. The at least one multifilament plied strand made of aramid and the at least one multifilament plied strand made of polyester are twisted together.||08-27-2015|
|20150239296||PNEUMATIC TIRE TREAD AND PNEUMATIC TIRE WITH SAID TREAD - A pneumatic tire tread having a reinforcing part on front surface side walls of a block to improve performance on ice while improving performance on snow, and a pneumatic tire having such a tread, wherein the difference G between a distance Rt measured from the tire axis of rotation to the outermost side of the upper surface of the block and a distance Re measured from the tire axis of rotation to two front surface edges is between 0.2 mm and 2.0 mm in a new article, the distance from the axis of rotation to any point in the region of the block upper surface excluding the front surface edge is greater than Re, and the distance between the portion at the outermost side of the reinforcing part measured in the radial direction and the front surface edge is no greater than 2.0 mm.||08-27-2015|
|20150239192||METHOD FOR CUTTING A STRIP OF TIRE REINFORCING PRODUCT COMPRISING WIRES AT AN ANGLE TO THE LONGITUDINAL DIRECTION OF THE PRODUCT - Method for cutting to length a strip formed of preassembled products comprising one or more rubber profiled elements superposed in part on a reinforcing ply made up of threads coated in rubber and making an angle (a) with the longitudinal direction of the strip, during which method the following steps are performed:||08-27-2015|
|20150239157||Automatic StartUp and Continued Operation of Calendering Drives for Elastomeric Mixes - The present invention relates to a method that allows the automatic and hands-free threading of a calender set of rolls comprising one or more pairs of rolls that have a nip between them by preventing the skim from sticking to a roll undesirably as it exits the nip. This is particularly useful during startup or when the continuous running of skim through the calender is interrupted or broken. This method also comprises steps that help prevent the interruption of the calendering process including the breaking of the skim being processed. The steps for startup include running the rolls to which the elastomeric mix is desired to stick at slower speeds than other rolls. The steps for maintaining continuous running of the calender after startup include running the rolls to which the elastomeric mix is desired to stick at faster speeds than other rolls.||08-27-2015|
