Elastomeric drive belt

An endless elastomeric drive belt comprising:

• (a) an endless body having an interior surface, an exterior surface and a pitch line located therebetween extending in a longitudinal direction;
• (b) a ply of spirally wrapped cable reinforcement extending in the longitudinal direction parallel to the interior and exterior surfaces and located at or near the pitch line and when placed under tension defining a first lateral force;
• (c) a first bias ply of cable reinforcement laid on an angle to the longitudinal direction outwardly of said spirally wrapped cable and in the same direction from the longitudinal direction as the spirally wrapped cable, and defining in use a second lateral force;
• and
• (d) a second bias ply of cable reinforcement laid on an angle to the longitudinal direction outwardly of said first bias ply which angle is equal in magnitude and opposite in direction to said first bias ply angle and at such a distance from the pitch line to generate a third lateral force which neutralizes the sum of the first and second lateral forces.
