A paper machine belt that includes a cross-machine direction supporting layer providing strength in the cross-machine direction and at least two additional layers. The two additional layers include polymeric material and at least one of the additional layers that includes the polymeric material is positioned on one side of the cross-machine direction supporting layer and at least another of the additional layers that includes the polymeric material is positioned on an opposite side of the cross-machine direction supporting layer. The cross-machine direction supporting layer substantially includes cross-machine direction yarns loosely bound together with very fine machine-direction yarns. A ratio of mass of the cross-machine direction yarns to the machine direction yarns being at least 160:1, and mass of the polymeric material of the additional layer on the one side of the cross-machine direction supporting layer is substantially the same as a mass of the polymeric material of the additional layer that is provided on the opposite side of the cross-machine direction supporting layer.
