Abstract
A forming fabric for use in papermaking machines having a paper support surface and a machine contact surface. The support surface comprises first weft yarns interwoven in a weaving pattern with warp yarns to form a weft dominated surface having alternating weft floats of first and second lengths. These floats are formed by the first weft yarns passing over different numbers of adjacent warp yarns in each pick of the weft across the weave pattern. The contact surface is woven with the second weft yarns weaving with the warp yarns in a weave pattern which also forms a weft dominated surface. The second weft yarns are passed under a greater number of adjacent warp yarns in each pick across the weave pattern than the first weft yarns are passed over forming the contact surface with very long weft floats.
