    • A papermaker's fabric, usable in the forming section of a paper machine, having two layers of cross-machine-direction (CD) yams. Interwoven with the CD yams is a system of MD yams. At least some of the MD yams are grouped into alternating pairs comprising a crossing pair having a first MD yam and a second MD yarn and a second pair having a third MD yarn and a fourth MD yam. The first MD yam and the second MD yam combine to weave each CD yam in the first layer and cross between the first layer and the second layer. The left and right warp yarns in the pairs are aligned in such a way that like adjacent yams from adjacent pairs have MD cell lengths greater than or less than the MD cell lengths from non-like adjacent yams from adjacent pairs. The third MD yam is interwoven with the first layer of CD yarns and the fourth MD yam is interwoven with the second layer of CD yams. In this manner, a paired warped triple layer forming fabric may be produced which minimizes drainage and crossover point topographical markings.
    • 造纸机的织物,可用于造纸机的成形部分,具有两层机器横向(CD)纱线。 与CD山药交织是一种MD山药系统。 至少一些MD纱线被分组为交替对,其包括具有第一MD纱线和第二MD纱线的交叉对和具有第三MD纱线和第四MD纱线的第二对交叉对。 第一MD纱线和第二MD纱线组合起来在第一层中编织每个CD纱线并在第一层和第二层之间交叉。 成对的左右经纱以这样的方式对齐,即来自相邻对的相邻纱线具有大于或小于来自相邻对的非相似相邻纱线的MD单元长度的MD单元长度。 第三根MD纱线与第一层CD纱线交织,第四根MD纱线与第二层CD纱线交织。 以这种方式,可以生产成对的翘曲三层成形织物,其使排水和交叉点地形标记最小化。
