An endless fabric comprises a pin seam in which a pintle wire joins loops 26 formed by machine-direction yarns at the ends 22,24 of an open-ended papermachine fabric, wherein the pintle wire 28 is an extrudeed monofilament having a length at least as great as the width of the fabric and having a non-circular cross-section of which the major and minor dimensions lie respectively in and perpendicular to the plane of the fabric. The major dimension of the pintle stretches the loops and reduces seam gap. The minor dimension is approximately equal to the thickness of the fabric under load. Both serve to reduce the marking of the paper sheet by the seam region. |
