The present invention discloses an improved single-wire or twin-wire draw paper machine for making paper in combination with a papermaking belt. The present invention is adapted to make hard grades of a paper with reduced wear of papermachine clothing. The papermaking belt carries a nascent paper web. The papermaking machine comprises at least two belts. Each belt has mutually opposed faces: a paper-contacting face and a machine-contacting face. Each belt comprises a reinforcing element of woven filaments with a patterned framework. The framework has a pattern independent of the reinforcing element. The pattern of the framework defines at least one of a first face and a second face. The two belts each have a mutually different pattern in the framework.
