Abstract
A high elongation cable and a tire having a tread belt with an extensible reinforcing cable are provided. The high elongation cable has a 3×7×m or a 4×7×m construction, wherein m is comprised of at least two layers, wherein the outermost layer is comprised of a plurality of twisted filaments, said filaments having a diameter d, wherein the spacing between said twisted filaments is less than the diameter d.
Claims4
A high elongation cable having a 3×7×m construction, wherein m is comprised of two or more layers, wherein the outermost layer is comprised of a plurality of twisted filaments, said filaments having a diameter d, wherein the spacing between said twisted filaments is less than the diameter d, wherein m is comprised of at least two layers, wherein m is selected from the group consisting essentially of:
- [1+6+12×0.22], [3×0.20+7×0.23], [3+9×0.25], and [1+6×0.35], and wherein the cable has a tensile strength of at least 27,500 N and 3% elongation.
A high elongation cable having a 4×7×m construction, wherein m is comprised of two or more layers, wherein the outermost layer is comprised of a plurality of twisted filaments, said filaments having a diameter d, wherein the spacing between said twisted filaments is less than the diameter d, wherein m is selected from the group consisting essentially of:
- [1+6+12×0.22], [3×0.20+7×0.23], [3+9×0.25], and [1+6×0.35], and wherein the cable has a tensile strength of at least 27,500 N and 3% elongation.
