Papermaker's forming fabric

A papermaker's monoplanar fabric comprising interwoven warp and filling yarn systems, alternate warp yarns of said warp yarn system being woven in a preselected conventional unbalanced pepermaker's weave pattern chosen from the class consisting of a 1/2 twill, a 2/1 twill, a 1/4 twill, a 4/1 twill, a 2/3 twill, a 3/2 twill, a 1/5 twill, a 5/1 twill, a 1/4 sateen and a 4/1 sateen, the remaining warp yarns of said warp yarn system bing inverted so as to occupy positions with respect to said filling yarns opposite to those positions which they would occupy according to said preselected conventional unbalanced papermaker's weave pattern so that each fill yarn has an equal number of warp yarns passing thereover and thereunder, whereby the forces within said fabric are balanced reducing the tendency of edge curl and said fabric is provided with an improved support surface.
