ABSTRACT:
A belt for use on a long nip press for dewatering a fibrous web includes a base assembled by spirally winding a prepared structure strip 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 thus formed. The prepared structure strip may be a fabric strip woven from lengthwise and crosswise yarns, which may be monofilament yarns of a synthetic polymeric resin. The fabric strip may be of either a single- or multi-layer weave. At least one side of the base, namely, that side which will be on the inside of the belt in its endless loop form, and which slides over the arcuate pressure shoe component of the long nip press during its operation, is coated with a polymeric resin, such as polyurethane, to render it impervious to liquids, and especially to the oil used to lubricate the surface of the arcuate pressure shoe. The coating is ground and buffed to provide the belt with a smooth surface and a uniform thickness.
