<p>A two-layer paper machine cloth includes first and second longitudinal yarn systems and at least three transverse yarn systems. To provide effective drainage, at least one transverse yarn system is situated on the paper-forming side of the cloth and at least two transverse yarn systems are situated on the wear side. One of the yarn systems of the wear side consists of yarns having a smaller diameter than the other yarns. The first longitudinal yarn system weaves only with the larger diameter transverse yarns or, alternatively, both with the larger diameter and the smaller diameter yarns and the second longitudinal yarn system weaves only with the smaller diameter longitudinal yarns.</p> |
