An on-machine-seamable (OMS TM ) papermakers' fabric produced by modified endless weaving includes machine-direction (MD) and cross-machine direction (CD) yarns. The MD yarns are plied/twisted yarns, and weave continuously back-and-forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. A seaming spiral, a monofilament spiral preferably extruded from a polyamide resin, is attached to the seaming loops at each of the two widthwise edges. The two seaming spirals are used to join the fabric into endless form with a pin seam. In this way, an OMS TM papermakers' fabric, having plied/twisted yarns in the machine direction is provided with monofilament joining means which maintain proper orientation and shape for the ready pin seaming of the fabric on a papermachine. <IMAGE> |
