摘要： A method of forming a bead assembly for use in a pneumatic tire includes extruding a strip of green elastomeric material onto a split or pair of steel supporting guide ring where the ends of the extruded strip are cut at a bias angle and then spliced together to form an annular elastomeric member. The extruded strip and formed annular member has a pair of tapered longitudinal end members joined by a central recess. An annular tire bead is placed in radial alignment about the central recess of the annular member. Next, a segmented mandrel carrying inflatable turnup bladders is expanded outwardly, afterwhich the split guide ring is axially withdrawn. The mandrel and bladders then provide the support for the elastomeric member previously provided by the split annular ring, and traps the bead within the central recess. The two longitudinal end members of the extruded strip are then turned up about the bead by inflating the bladders to form the bead assembly, afterwhich the assembly is placed in a shaping mold. If desired, an annular strip of reinforcing material may be placed concentrically about the bead before the end members are turned up about the bead, to provide internal reinforcement for the bead assembly.

摘要： A tire cure control system and method characterized by a computer-based data acquisition and process control unit that uses non-invasive, direct cure measurements to adjust the length of cure so that all cured articles such as tires will be cured to the same extent in the minimum amount of time, thereby to maximize production while providing uniformly cured products. The unit generally includes at least one microwave probe, although preferably multiple microwave probes, placed in the mold and a processor to process probe data and to initiate a control action principally initiating a mold opening sequence at the optimal time. Initiation of the mold opening sequence at least in part is based upon a measurement of the time rate of change of the attenuation of microwave energy caused by the curing rubber compound in the mold.
