PROBLEM TO BE SOLVED: To place a pressing fabric easily seamable on a paper machine. SOLUTION: An on-machine-seamable papermaker's fabric produced by modified endless weaving includes machine-direction (MD) and 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 1st CD yarns are interwoven with one another in a first weave pattern. The fabric also includes systems of 2nd and 3rd CD yarns. The 2nd CD yarns are interwoven with the MD yarns along one of the two widthwise edges of the fabric between the system of 1st CD yarns and the seaming loops in a 2nd weave pattern which may be different from the 1st weave pattern. Likewise, the 3rd CD yarns are interwoven with the MD yarns along the other of the two widthwise edges of the fabric between the seaming loops in a 3rd weave pattern. The 2nd and 3rd weave patterns may be the same as or different from one another. The 2nd and 3rd CD yarns may make the compressibility and permeability characteristics of the seam regions like those of the rest of the fabric, or may improve the stability, uniformity and orientation of the seaming loops at the two ends of the fabric.
