20100200143 | ANNULAR CONCENTRIC STRANDED BEAD CORD, METHOD FOR MANUFACTURING THE SAME, AND VEHICLE TIRE - There are provided an annular concentric stranded bead cord which can realize a reduction in weight while ensuring its strength, a method for manufacturing the same and a vehicle tire. | 08-12-2010 |
20100200142 | ANNULAR CORE STRANDED BEAD WIRE AND VEHICLE TIRE USING THE SAME - An annular core stranded bead wire having a reduced weight and offering ease in manufacturing and handling and a vehicle tire using such a bead wire are provided. | 08-12-2010 |
20090260735 | BEAD CORD AND VEHICLE TIRE - A bead cord is described including an annular core and a side wire. The side wire is helically wound around the annular core. Further, the annular core is made of a strand wire. The strand wire includes a plurality of twisted core wires. The plurality of core wires may have substantially the same diameter. | 10-22-2009 |
20090258228 | STEEL WIRE FOR SPRING - Spring steel wire is formed by drawing steel wire including a phosphate film, the weight of the film being in the range of 3.0 to 5.5 g/m | 10-15-2009 |
20090205741 | CONNECTION METHOD OF METAL LINEAR ELEMENT AND CONNECTION DEVICE OF METAL LINEAR ELEMENT - A connection method for connecting metal linear objects facing each other includes disposing a pair of rotators with a space interposed therebetween. Each rotator including a pair of holding portions that are provided with a space interposed therebetween and that are able to hold the metal linear objects. The connection method also includes holding the vicinities of end portions of the metal linear objects at the holding portions of the rotators to hang the metal linear objects therebetween so that the vicinities of the end portions of the metal linear objects are overlapped with each other in an axis direction and rotating the rotators relatively in the opposite directions around between the pair of holding portions as a rotation center. As a result, the metal linear objects are twisted with each other between the rotators to perform connection. | 08-20-2009 |
20090136697 | ANNULAR METAL CORD, ENDLESS METAL BELT, AND METHOD OF PRODUCING ANNULAR METAL CORD - An annular metal cord includes an annular core portion formed in an annular shape, and an outer layer portion spirally wound around the annular core portion while running over an annular circumference thereof plural times and covering an outer peripheral surface of the annular core portion. Each of the annular core portion and the outer layer portion are formed by a strand material which is formed by intertwisting a plurality of metal filaments. At least part of the outer layer portion is covered with an outer layer sheath made of a coating material having elasticity. | 05-28-2009 |
20090133798 | PROCESS FOR PRODUCING WIRE FOR BEAD CORD, BEAD CORD, AND VEHICLE TIRE - A method for manufacturing a bead cord wire includes the steps of subjecting a steel wire to a descaling treatment, subjecting the descaling-treated steel wire to a chemical conversion coating treatment through electrolysis so as to form a phosphate coating on a surface of the steel wire, and subjecting the chemical-conversion-coating-treated steel wire to drawing so as to produce a bead cord wire. In producing the bead cord wire, the drawing is conducted in such a way that the phosphate coating remains on the surface of the bead cord wire. | 05-28-2009 |
20090088278 | ANNULAR METAL CORD, ENDLESS METAL BELT, AND ANNULAR METAL CORD MANUFACTURING METHOD - An annular metal cord includes an annular core portion formed in an annular shape, and an outer layer portion spirally wound around the annular core portion while running over an annular circumference thereof plural times and covering an outer peripheral surface of the annular core portion. Each of the annular core portion and the outer layer portion are formed by a strand material which is formed by intertwisting a plurality of metal filaments. The annular core portion and the outer layer portion are formed by a continuous strand material. | 04-02-2009 |
20080277040 | Connector For A Wrap Wire Of A Bead Cord - An object of the present invention is to prevent shifting of a connector for a wrap wire, reduced strength of the connector, and deterioration in balance, and to make it possible to easily connect the ends of the wrap wire. | 11-13-2008 |
