<p>A pressing arrangement for use in a papermaking machine comprises: permeable first and second fabrics with a paper web disposed thereinbetween; and a differential pressure arrangement acting on at least one of the first and second fabrics and the paper web and providing a differential pressure between the first fabric and a support surface, the paper web being subjected to mechanical pressure and experiencing a hydraulic pressure so as to cause water to be drained therefrom, the pressing arrangement allowing air to flow in a direction through said first fabric, the paper web, and the second fabric. The first fabric includes a fabric woven from a repeating pattern of weft yarns and warp yarns, wherein each weft yarn has a repeated sequence of going over three adjacent warp yarns, under one warp yarn, over one warp yarn, under three warp yarns, over one warp yarn, and under one warp yarn.</p> |
