ABSTRACT:
A papermaker's fabric, usable in the forming section of a paper machine, having two layers of cross-machine-direction (CD) yarns. Interwoven with the CD yarns is a system of MD yarns. The MD yarns are grouped into alternating pairs comprising a crossing pair having a first MD yarn and a second MD yarn and a second pair having a third MD yarn and a fourth MD yarn. The first MD yarn and the second MD yarn combine to weave each CD yarn 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 yarns from adjacent pairs have MD cell lengths equal to or less than the MD cell lengths from non-like adjacent yarns from adjacent pairs. The third MD yarn is interwoven with the first layer of CD yarns and the fourth MD yarn is interwoven with the second layer of CD yarns. In this manner, a paired warped triple layer forming fabric may be produced which minimizes drainage and crossover point topographical markings.
