Abstract

A press belt for the formation of a nip between the belt and an opposing surface during processing of a fibrous pulp web, that includes a matrix of an elastomer material, a first layer of reinforcing fibers having a thickness and spacings therebetween, and extending in a direction transverse to a belt run direction, and a second layer of reinforcing fibers having a thickness and spacings therebetween, and extending in the belt run direction, where the thicknesses of the reinforcing fibers of the first layer and the second layer is about 0.5 mm, where the spacings between the reinforcing fibers of the first layer are less than or equal to about 3.0 mm, where the spacings between the reinforcing fibers of the second layer being less than or equal to 2.5 mm, and where the reinforcing fibers of the first layer are separated in a belt thickness direction from the reinforcing fibers of the second layer one layer by a distance of up to about 4 mm.
