Abstract
A papermaker's forming fabric comprising a fabric layer including cross machine direction fabric yarns and machine direction fabric yarns interwoven to form a papermaking surface with alternating single knuckles thereon. First additional cross machine direction yarns are positioned between adjacent cross machine direction fabric yarns on the papermaking surface of the fabric layer. Second additional cross machine direction yarns are positioned between the cross machine direction fabric yarns on the papermaking surface of the fabric layer. Each of the first and second additional cross machine direction yarns serve as paper stock fiber supporting yarns and as locator yarns for another of the first and second additional cross machine direction yarns. Each of the first and second additional cross machine direction yarns are interwoven with the fabric layer to float over odd numbers of adjacent fabric layer machine direction yarns.
