Patent ID: 7074729

Claim:
A composite sheet, comprising: a fabric that is at least partially embedded in a polymeric sheet, with the fabric including warp yarns extending in a longitudinal direction and weft yarns extending in a lateral direction that is at least about perpendicular to the longitudinal direction, wherein: the polymeric sheet includes: longitudinally extending edges that are laterally spaced apart from one another, outer, longitudinally extending, first and second surfaces that extend laterally between, and are contiguous with, the edges, and a thickness that is defined between, and substantially perpendicular to, the first and second surfaces; all of the warp yarns of the composite sheet and all of the weft yarns of the composite sheet: are positioned between the first and second surfaces, and are not exposed at either of the first and second surfaces; pluralities of longitudinally extending first and second areas of the polymeric sheet are arranged in an alternating, laterally extending series such that each of the first areas is contiguous with at least one of the second areas, for each of the first areas: at least a plurality of the weft yarns extend laterally through the first area, and at least a plurality of the warp yarns extend longitudinally through the first area; and for each of the second areas: none of the warp yarns of the composite sheet are located in the second area; at least a plurality of the weft yarns extend laterally through the second area; the second area has a laterally extending width and includes all of the thickness of the polymeric sheet that is within the width, and the width of the second area is at least about 0.3 inches; wherein at least one of the longitudinally extending edges of the composite sheet is a cut edge formed by cutting a wider composite sheet along a longitudinal cut line located in one of the second areas of the sheet such that the weft yarns extend all the way to the cut edge and terminate at the cut edge.
