Abstract
A method and apparatus for reducing the magnitude of a uniformity characteristic in a cured tire and the tire produced thereby. A signal is generated which is indicative of the magnitude of the uniformity characteristic. The signal is also indicative of the location on the tire to be corrected. At least a portion of one carcass reinforcing member of the tire is permanently deformed a predetermined amount at the location indicated by the signal to correct the uniformity characteristic.
Claims50
A method for reducing the magnitude of a uniformity characteristic in a cured tire, said method comprising the steps of:
- generating a signal indicative of the magnitude of the uniformity characteristic and the location on the tire to be corrected;
- and
- permanently deforming as a function of the magnitude of the uniformity characteristic at least a portion of at least one carcass reinforcing member of the tire at the location indicated by the signal.
An apparatus for reducing the magnitude of a uniformity characteristic in a cured tire generated by the tire during a uniformity characteristic test, said apparatus comprising:
- means for generating a signal indicative of the magnitude of a uniformity characteristic and the location on the tire to be corrected;
- and means for permanently deforming as a function of the magnitude of the uniformity characteristic at least a portion of at least one carcass reinforcing member of the tire.
A method for correcting a uniformity characteristic in a cured tire containing carcass reinforcing members, the correction being a function of indications of the magnitude and location of the uniformity characteristic, said method comprising the steps of causing permanent deformation of at least one portion of at least one carcass reinforcing member at a location selected in response to an indication of location of the uniformity characteristic, and controlling the magnitude of the deformation to said at least one portion of at least one carcass reinforcing member at the selected location in response to an indication of the magnitude of the uniformity characteristic.
An apparatus for correcting a uniformity characteristic in a cured tire containing carcass reinforcing members, the correction being a function of indications of magnitude and location of said uniformity characteristic comprising:
- means for causing permanent deformation of at least one portion of at least one carcass reinforcing member at a location selected in response to an indication of location of the uniformity characteristic;
- and
- means for controlling the magnitude of deformation by said deformation causing means to said at least one portion of at least one carcass reinforcing member at the selected location in response to an indication of the magnitude of the uniformity characteristic.
