Abstract
A single ply forming fabric for use on a twin wire paper making machine wherein a flat jet stream of pulp is injected between an inner, conveying fabric and an outer, backing fabric converging towards each other for applying opposed pressure to the pulp for removing water therefrom to form a sheet of pulp. The single ply forming fabric of the present invention constitutes the outer, backing fabric and is interwoven with a plurality of monofilament polymeric warp strands with approximately 100% warp fill and monofilament polymeric weft strands extending in the cross-machine direction and disposed in vertically aligned groups of at least three to obtain greater stiffness in the cross-machine direction whereby to substantially redistribute pulp widthwise of the sheet when supported on the conveying fabric.
