Abstract
A papermaker's fabric, usable in a forming section of a paper machine, having a first layer formed of a first system of paired machine-direction (MD) warp yarns interwoven with a first system of cross machine-direction (CD) weft yarns and a second layer formed of a second system of MD warp yarns interwoven with a second system of CD weft yarns. The paired MD warp yarns are intrinsic to the first layer and are interwoven with the second system of CD weft yarns to bind the second layer to the first layer. The second system of MD warp yarns forms long floats, or warp-runners, on an external surface of the second layer. In this manner, a triple layer forming fabric with paired intrinsic binders and warp-runners may be produced with improved wear side abrasion resistance.

A papermaker's fabric comprising:
- a first layer formed of a first system of paired machine-direction (MD) warp yarns interwoven with a first system of cross machine-direction (CD) weft yarns;
- and
- a second layer formed of a second system of MD warp yarns interwoven with a second system of CD weft yarns;
- wherein the paired MD warp yarns are intrinsic to said first layer or said second layer, and are interwoven with said second system of CD weft yarns to bind said second layer to said first layer;
- wherein the second system of MD warp yarns forms long floats on an external surface of said second layer.
