摘要

A double layer forming fabric for a paper making machine is woven to an overall repeating pattern, which comprises in combination paper side layer weft yarns (120), machine side layer weft yarns (130), and warp yarns (140). The paper side layer weft yarns (120) interweave with the warp yarns (140) in a first repeating weave pattern, the machine side layer weft yarns (130) interlace with the warp yarns (140) in a second repeating weave pattern, and the fabric is woven in an overall repeating pattern requiring 3N sheds, in which N is an integer and is at least 2. For each warp yarn (140), the first repeating weave pattern includes interweaving locations comprising a first (106) and a second (108) interweaving point, each of the interweaving points being separated by an internal warp float of at least two paper side layer weft yarns. For each warp yarn, the second repeating weave pattern includes a series of interlacing points (114, 116) in which each interlaced machine side layer weft yarn (130) also passes substantially below an interweaving location (105, 107) of paper side layer weft yarns and each adjacent warp yarn. In addition, for each warp yarn (140), each of the first and second interweaving points (106, 108) with a paper side layer weft yarn (120) is separated from an adjacent machine side layer interlacing point by at least two machine side layer weft yarns. The machine side face of the machine side layer includes exposed machine side layer weft yarn floats having a float length L defined as L= 3N - M, wherein M is an integer and is at least 1.
