Patent ID: 8622095

Claim:
A papermaking machine for the production of a fibrous web, comprising: a plurality of rollers; and a structured fabric moving along said plurality of rollers, said structured fabric having a machine facing side and a web facing side, said structured fabric including: a plurality of weft yarns; and a plurality of warp yarns interacting with said weft yarns to produce a weave pattern, said plurality of warp yarns including a first set of warp yarns and a second set of warp yarns, said first set of warp yarns being woven as a plain weave, said second set of warp yarns forming an impression layer, said first set of warp yarns being in a first plane, said second set of warp yarns having a surface in a second plane, said second plane being positioned farther from said machine facing side than said first plane to form the impression layer, said first set of warp yarns have a first cross-sectional area and said second set of warp yarns have a second cross-sectional area, said first cross-sectional area being less than said second cross-sectional area, wherein each of said second set of warp yarns floats at least one time per weave repeat over at least three consecutive weft yarns and wherein between each pair of adjacent yarns of said second set of warp yarns a single one of said first set of warp yarns is located and between each pair of adjacent yarns of said first set of warp yarns a single one of said second set of warp yarns is located.
