ABSTRACT:
A belt for use on a long nip press for dewatering a fibrous web includes a base fabric, woven from machine-direction and cross-machine directions yarns and taking the form of an endless loop. The base fabric many be woven from monofilaments yarns of a synthetic polymeric resin in either a single- or a multi-layer weave. At least one side of the base fabric, 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, especially lubricating oil. The coating is reinforced with a flexible layer of reinforcing fiber which may take the form of a woven sheet or may be in single filament form in single or multiple layers thereof. When in single filament form, each layer includes filaments disposed adjacent and substantially parallel to one another. The reinforcing fiber may be of a synthetic polymeric resin or of metal. In either case, the reinforcement renders the coating less susceptible to cracking and to damage from foreign objects while the belt is in use on the long nip press.
