Abstract
A papermakers fabric having surface floats on both the paper surface and the non-paper contacting surface for improved sheet contact area and improved abrasion resistance. The fabric also includes a plurality of stuffer pick receiving sheds defined by warp yarns of non-circular cross section used to weave the fabric. In a preferred embodiment, the warp yarns are of generally rectangular cross section with rounded corners. Each of these sheds may receive a stuffer pick, the construction of which will be determined by the permeability required in the finished fabric, while the warp and weft yarns used to define the fabric remain unchanged. The warp ends of the fabric terminate in a pin seam made up of a number of enlarged seam loops which are created when a select number of the warp yarns of non-circular cross section are symmetrically rewoven into the fabric.
