Abstract
A paper machine having a forming fabric with a paper side plurality of weft and warp yarns interwoven to form a layer contacting a paper web. A plurality of weft and warp yarns are interwoven to form a machine side layer for the forming fabric. A plurality of warp binder yarns are interlaced with the paper side and machine side yarns to form a multiple layered forming fabric. The weft yarns in the machine side layer are greater in diameter than the warp yarns for maintaining width stability of the fabric. The fabric is characterized by high permeability, high void volume and a high Beran's Fiber Support Index.
