Embodiment Construction

[0027] Reference will now be made in detail to embodiments, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the embodiment, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and changes can be made in the embodiments without departing from the scope or spirit of the present disclosure. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a further embodiment. Accordingly, it is intended that aspects of the present invention cover such modifications and variations.

[0028] overview

[0029] Example aspects of the present disclosure relate to systems and methods for improving the uniformity of a tire by selectively removing tire material from a plurality of different tracks along a bead portion of the tire. Tire uniformity correction may be accomplished by cutting one or mo...

Abstract

Systems and methods for correcting uniformity of a cured tire using ablation of material along a plurality of tracks along the bead portion of the tire are provided. An ablation pattern can be determined to correct for a uniformity parameter for multiple tracks along a bead portion of a tire. The ablation pattern for each track can be analyzed to determined direct address commands for implementing the ablation pattern using an ablation device. The direct address commands can be determined according to an adjustment process to improve cycle time for the ablation of a tire. The adjustment process can be operable to more closely align azimuthal positions of ablation segments specified by direct address commands for different tracks along the bead of the tire.

Description

[0001] priority claim [0002] This application claims priority to PCT / US15 / 41477 filed in the United States Receiving Office on July 22, 2015, which is incorporated herein by reference. technical field [0003] The present disclosure relates generally to systems and methods for improving tire uniformity, and more particularly, to systems and methods for improving tire uniformity by selectively removing material along tire bead locations in cured tires . Background technique [0004] Among specific quantifiable characteristics of a tire, tire non-uniformity is related to symmetry (or lack thereof) about the tire's axis of rotation. Unfortunately, conventional tire building methods have many opportunities for creating non-uniformities in the tire. During tire rotation, non-uniformities that exist in the tire structure generate periodically varying forces at the wheel axis. Tire non-uniformity is important as these force variations are transmitted as significant vibrations...
