Abstract
Abstract A woven fabric for reinforcing a resilient material, such as a tire casing, wherein the warp of the fabric consists of substantially unstranded wires held together in spaced groups by the weft of the fabric with at least some of the wires being formed with a set so as to have undulations along their length to thereby improve the adhesion between the wires and resilient material as well as to improve the tensile and compression stress characteristics of the wires. The amplitude of the undulations may be perpendicular to the direction in which the groups are spaced from each other. The undulations may also be periodic with the phase of such undulations being either the same or different between adjacent groups.
