| 20090260743 | TIRE MANUFACTURING METHOD FOR IMPROVING THE UNIFORMITY OF A TIRE - A tire manufacturing method includes a method for optimizing the uniformity of a tire by reducing the green tire radial runout. The green tire radial runout is modeled as a vector sum of each of the vectors representing contributions arising from the tire building steps. A set of vector coefficients is generated from the vector equation. The building steps include building the tire carcass, building the tire summit, transferring the summit onto the inflate carcass, and measuring the radial runout and tooling angles at each step in the process. After the model is built the vector equations and coefficients are applied to subsequent tires. By adjusting the tooling angles, green tire radial runout can be optimized. | 10-22-2009 |
| 20110114251 | TIRE MANUFACTURING METHOD FOR IMPROVING THE UNIFORMITY OF A TIRE - A tire manufacturing method includes a method for optimizing the uniformity of a tire by reducing the after cure radial force variation. The after cure radial force variation vector is modeled as a vector sum of each of the vectors representing contributions arising from the tire building steps—the “tire room effect vector” and a vector representing contributions arising from the vulcanization and uniformity measurement steps—the “curing room effect vector.” In further detail, both the tire room and curing room effect vectors can be further decomposed into sub-vectors representing each radial force variation contribution for which a measurable indicator is available. For a series of tires, the method obtains such measurements as the before cure radial runout (RRO) at one or more stages of the building sequence, measurements of loading angles on the tire building equipment, and measurements made during vulcanization process. | 05-19-2011 |
| 20120031179 | TIRE UNIFORMITY THROUGH DISPERSION OPTIMIZATION - A system and related method for improving tire uniformity includes providing at least one set of test tires constructed with one or more process elements provided at known relative angular locations. At least one uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for at least one harmonic of interest for each test tire. Respective rectangular coordinates are determined for each measured uniformity parameter and harmonic of interest for each tire. A form of the determined rectangular coordinates (e.g., the rectangular coordinates themselves and/or the log of the residuals squared) is analyzed for each tire to identify optimized relative angular locations for each process element that reduce dispersion (or dispersion and mean) of the measured uniformity parameter. New tires are built with the one or more process elements positioned in the identified optimized relative angular locations. | 02-09-2012 |
| 20120035757 | IMPROVEMENT OF TIRE UNIFORMITY THROUGH IDENTIFICATION OF PROCESS SIGNATURES - A system and related method for improving tire uniformity includes providing a number (n) of test tires manufactured in a known order and identifying at least one candidate cyclic process effect with a corresponding frequency of introduction (f). A given uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for each tire in the test set, and measured data points are combined into a concatenated composite waveform. At least one process harmonic associated with each identified cyclic process effect is separated from the tire harmonics, for example, by Fourier transformation with identification of the process harmonics as positive integer multiples of the mth harmonic of the measured uniformity parameter where m=n/f. Once the process harmonics are extracted, filtered uniformity measurements can be provided or new tires can be built with the process effect minimized. | 02-09-2012 |
