ABSTRACT:
A wire former comprising a structural framework, a headbox for holding and dispensing the pulp slurry, a breast roll, a couch roll, a forming fabric belt extending endless between the breast roll and the couch roll in a straight run, and drainage elements and suction devices underlying said straight run for extracting liquid from the slurry. The forming fabric is a multi-ply fabric, the uppermost ply being a self-sustaining weave with monofilament warp yarns of a given diameter interwoven with shute yarns, the lowermost ply being a weave with a series of generally ovate warp yarns having a vertical dimension generally equal to the diameter of the warp yarns of the uppermost ply, interwoven with shute yarns. The ovate warp yarns have a horizontal width in the shute direction substantially greater than their vertical dimension. Binder shute yarns interconnect the upper and lower plies by being interwoven with the upper and lower plies so as to be contained within the body of the multi-ply fabric.
