Abstract
Abstract Three-ply belting having improved dimensional stability, flexing characteristics, and elongation characteristics is disclosed. The center ply of the belt comprises a first synthetic fabric, while each outer ply comprises a second synthetic fabric. The modulus and flex fatique life of the second synthetic fabric are respectively greater than the modulus and flex fatique life of the first synthetic fabric. Belting in accordance with the present invention is useful in agricultural applications.
