A long nip press belt for a long nip press on a paper machine includes an endless base support substrate, a staple fiber batt attached to at least one of the two sides of the endless base support substrate, and polymeric resin materials totally impregnating the fiber/base composite structure comprising the endless base support substrate and the staple fiber batt. A layer of polymeric resin material 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.
