<p>A belt (16) for use on a long nip press (10) for dewatering a fibrous web (24) includes a base (40) assembled by spirally winding a prepared structure strip (34) in a plurality of non-overlapping turns. Successive turns are abutted against and joined to those previously wound by sewing or otherwise bonding along the continuous spiral seam 38 thus formed. The prepared structure strip (34) may be a fabric strip (34) of a single- or multi-layer weave, woven from lengthwise (48) and crosswise yarns (50), which may be monofilament yarns of a synthetic polymeric resin. At least one side of the base (40), the side which will be on the inside of the belt and which slides over the pressure shoe (14) is coated with a polymeric resin, such as polyurethane, to protect it from wear and render it impervious to oil and water. The coating (54) is ground and buffed to provide the belt (16) with a smooth surface and a uniform thickness. <IMAGE></p> |
