<p>A papermaker's fabric (10) having a smooth surface and a prolonged life includes flat machine-direction yarns (26, 28) which define the upper and lower surfaces thereof. The fabric has two layers of cross-machine direction yarns (18, 18', 22, 22'), each of which is interwoven with the flat machine direction yarns (26, 28). Other machine direction yarns (24), of round cross section, weave with the cross-machine direction yarns (18', 22') in the two layers to bind them together. At one of the two ends of the fabric, seaming loops (30) are formed by the round machine-direction yarns. At the other of the two ends, seaming loops (34) are formed by the flat machine-direction yarns (26, 28). The seaming loops (30, 34) are interdigitated with one another, when the two ends of the fabric (10) are brought together during installation on the paper machine, defining a passage through which a seaming pin or pintle (42, 50, 58) is directed to join the two ends (30, 34) together.</p> |
