(54) Belts for shoe presses


(57) A long nip press belt (110) for a long nip press on a paper machine includes an endless base support substrate (112), a staple fiber batt (122) attached to at least one of the two sides of the endless base support substrate (112), and polymeric resin materials (128) totally impregnating the fiber/base composite structure (126,136) comprising the endless base support substrate and the staple fiber batt. A layer of polymeric resin material (130) is built up upon the fiber/base composite structure to a predetermined thickness on each side of the long nip press belt. Once the polymeric resin material is cured, at least the inside surface is ground to a desired smoothness without exposing any fiber on the ground surface.
