Abstract
A web forming fabric has a machine direction of intended movement on a web forming machine and a cross-machine direction substantially normal to the machine direction. The fabric includes machine direction yarns disposed generally in the machine direction and transverse yarns disposed generally transversely to the machine direction. The fabric includes first and second substantially linear arrays of systematically distributed areas of high drainage on one side thereof. These linear arrays are oriented at an acute angle to the machine direction and at an acute angle to each other. The boundaries of each of the systematically distributed areas are defined by two pairs of adjacent sides; the adjacent sides of one pair being angled segments of one transversely extending yarn and the adjacent sides of the other pair being angled segments of a second transversely extending yarn contiguous to the one transversely extending yarn. The opposite side of the fabric has long machine direction floats over adjacent transverse yarns and the machine direction floats of adjacent machine direction yams partially overlap each other in the machine direction.
