20090089992 | TIRE BEAD SEPARATION METHOD AND DEVICE - A method and apparatus is provided for separating two or more annular members such as bead assemblies or bead and apex assemblies. First, a flexible member is inserted into the annulus of the annular members. Next, the flexible member is inflated until the outer surface of the flexible member contacts the inner diameter of the annular member. Then the flexible member is axially expanded until the annular members are separated. Then the flexible member is deflated so that the annular members can be removed. | 04-09-2009 |
20100051177 | BEAD CONSTRUCTION METHOD FOR A TIRE - A method and apparatus for manufacturing an annular tire component such as a tire bead includes locating a toroidal support; placing an ejector nozzle in an interference relationship to the toroidal support; and simultaneously ejecting through the nozzle a continuous stream of an elastomeric belt component material in a suitably fluid state and a continuous length of at least one thread component disposed within the stream onto the toroidal support in a predetermined bead configuration. The bead configuration is at least partially defined by a relief in the nozzle ejection port and by the toroidal support onto which the bead is formed. Rotation of the toroidal support may be coupled with the simultaneous ejection of the elastomeric component and thread component in order to create an annular bead structure. A tire may be constructed having a desired bead configuration and location by means of the method and apparatus. | 03-04-2010 |

20120318440 | METHOD AND APPARATUS FOR FORMING AN ANNULAR ELASTOMERIC TIRE COMPONENT - A method of forming a tire apex and bead assembly is disclosed. The method and apparatus includes mounting a bead in a rotatable bead holder, rotating the bead and bead holder and extruding one or more passes of a continuous strip of elastomeric material onto the outer surface of the bead, and shaping the one or more passes of elastomeric material between two opposed rotating rollers. | 12-20-2012 |
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 |

20110118629 | DEVICES AND METHODS FOR CERVIX MEASUREMENT - A device for measuring a length of a cervix includes an elongate measurement member, a hollow member, a flange, a handle, and a locking mechanism. The elongate measurement member extends along a longitudinal axis and includes a measurement scale thereon. The hollow member is coaxial with and disposed over the elongate measurement member. The flange is offset from the longitudinal axis and attached to a distal end of the hollow member. The handle is attached to a proximal end of the measurement member. The locking mechanism is configured, when locked, to fix the hollow member relative to the measurement member and, when unlocked to allow the hollow member to slide along the measurement member and rotate about the longitudinal axis so as to place the flange in a desired position without moving the measurement scale. | 05-19-2011 |
