Abstract

A woven fabric for use on paper machines having a support surface and a running surface. The fabric comprises a first set of filaments disposed in generally parallel relationship and in a machine direction, a second set of filaments disposed generally in parallel relationship in a cross machine direction and transversely of said first set of filaments. These sets of filaments are interwoven with each other so as to be serpentinely configurated to provide a first grouping of machine direction filaments having coplanar support surface crossovers and a second grouping of sub-support surface crossovers. The cross machine direction filaments are arranged to have coplanar support surface crossovers which are also recessed below said machine direction first crossover grouping by an equal depth which is between 5% and 50% of the diameter of the machine direction filaments. The first grouping of the machine direction and the cross machine direction crossovers are spaced so as to define diagonally arranged cavities across the support surface of the fabric. The cavities are separated from each other across the support surface by the first grouping of machine direction crossovers and are interconnected in said machine direction along the length of the fabric at the cross machine direction crossovers.
