A conveyor belt or belting comprises a solid woven carcass impregnated and coated with rubber. The warp yarns (12, 13) are comprised of polyester filamentary yarns doubled with texturised polyester yarns. Where the solid woven carcass is woven as a four ply or more construction the inner warp yarns (13) travel along a straighter path than the two outermost warp yarns (12) such that the outermost warp yarns (12) create "pockets" at the surface of the carcass.
