Abstract
A papermaking fabric with increased stability is provided, due to the use of beam construction yarns which resist lateral, vertical and torsional deflection as well as compression when interwoven. The yarns are generally non-circular in cross-section and are preferably I-beam, H-beam, box-beam or a hybrid construction. Each type has certain advantages, with the hybrid construction being capable of multiple combined advantages.
