Abstract: An on-machine-seamable papermaker's fabric, which may be produced by modified endless weaving, includes machine-direction (MD) and cross-machine-direction (CD) yarns. When so produced, the MD yarns 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. Interwoven with at least one of the two sides, top and bottom, of the seaming loops at one or both widthwise edges are at least two additional CD yarns. The additional CD yarns interweave with the top and/or bottom of the seaming loops in a leno weave, which keeps the seaming loops in a common position vertically relative to the plane of the papermakers fabric, locks the seaming loops into a desired position and orientation with their planes perpendicular to that of the papermaker's fabric.

Abstract: An on-machine-seamable papermaker's fabric produced by modified endless weaving includes machine-direction (MD) and first cross-machine-direction (CD) yarns. The MD yarns 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. The MD and first CD yarns are interwoven with one another in a first weave pattern. The fabric also includes systems of second and third CD yarns. The second CD yarns are interwoven with the MD yarns along one of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a second weave pattern which may be different from the first weave pattern. Likewise, the third CD yarns are interwoven with the MD yarns along the other of the two widthwise edges of the fabric between the system of first CD yarns and the seaming loops in a third weave pattern which may be different from the first weave pattern.
