Abstract: This invention relates to a tire having an electrically non-conductive tread which contains an electrically conductive rubber strip which extends through at least a portion of the tread to its running surface in a wave configured shape, and therefore not a continuous straight line within said tread, in which at least a portion of the rubber strip is in a shape of, for example, a substantially sinusoidal, cycloidal and/or zigzag form, to thereby provide a mechanical self-locking configuration between tread segments through which the rubber strip extends and divides. In particular, said tread is composed of a cap/base configuration. The outer cap layer is of a relatively electrically non-conductive rubber composition having a running surface intended to be ground-contacting. The tread base layer, underlying the tread cap layer, is of a relatively electrically conductive rubber composition and is not normally intended to be ground-contacting. A thin rubber strip, unitary with and as an extension of said tread base layer, which is thereby relatively electrically conductive, extends radially outward from said tread base layer of which at least a portion of the rubber strip is in a form of a wave-shaped configuration through, and therefore within, said tread cap layer to an outer running surface of said tread cap layer. In practice therefore, said rubber strip extends from, and as a part of, said tread base layer through said tread cap layer. In practice, said thin layer extending in said tread cap exhibits substantially at least one half an undulation, and preferably substantially at least two undulations of its wave configured shape of, for example, a substantially sinusoidal, cycloid al and/or zigzag form. The form of the individual undulations of the wave shaped configuration of the strip within the tread may be the same or different.

Abstract: A pneumatic rubber tire containing at least one electrically conductive cord extending between its bead and tread portions to provide a path of least electrical resistance. The electrically conductive cord is comprised of at least one electrically conductive metal filament spirally wound around a centrally disposed core of at least one organic fiber. The electrically conductive cord does not extend to, and is exclusive of, an outer surface of the tire.

Abstract: An apparatus for testing the fatigue of a sample of cord or filament (12) by bending it over a fixed surface (19). The apparatus comprises a tensioner (14), a fixed bending surface (19) and a driving mechanism (24), whereby the driving mechanism (24) causes a non-twisting bending of cord or filament (12) over bending surface (19) while tensioner (14) maintains a constant tension on cord or filament (12). In a method of the invention, a cord or filament (12) is attached to a tensioner (14), the cord or filament (12) is mounted on fixed bending surface (19) and attached to non-stationary roller (20), and driving mechanism (24) is activated to cause a back and forth movement of roller (20), thereby causing filament or cord (12) to bend back and forth over fixed bending surface (19) until it breaks. This process is repeated using different stress increase rates on the cord or filament (12) by adjusting the tensioner (14) and a linear regression equation is used to determine the fatigue stress limit of the material.
