<p>A double layer forming fabric for use in a paper-making machine has a warp ratio of at least six strands and a shute ratio of at least twelve strands. The warp strands bind with the lower layer at locations distributed according to a satin weave pattern whose ratio is equal to the warp ratio; the warp strands bind with the upper layer at locations distributed according to a pattern whose aggregated ratio is equal to the warp ratio and which is constituted by the association of several weave patterns each having a warp ratio lower to 6 strands. There are at least two shute strands of the upper layer between two successive points where a warp strand comes down from the paper contacting face across the upper layer and then comes up again, respectively.</p> |
