Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
A sail fabric comprising a laminate of at least three layers, a central layer of said laminate being composed of a scrim comprising a pair of sets of spaced parallel yarns intersecting each other at acute angles relative to the cross machine direction of the machine on which the scrim is made to define a grid pattern, the outer layers being selected from film and cloth wherein said cloth comprises warp yarns and fill yarns, wherein lines bisecting acute angles are substantially parallel to the direction of said fill yarns and said cross machine direction, with said scrim yarns supporting said fabric in the cross machine direction and in the fill and bias directions, and adhesive means between said outer layers for securing the layers together and holding said sets of scrim yarns in said intersecting configuration.
Claim 2
Dependent Claim
137 words
A sail fabric comprising a laminate of at least three layers, a central layer of said laminate being composed of a scrim comprising a pair of sets of spaced parallel yarns intersecting each other at acute angles relative to the cross machine direction of the machine on which the scrim is made to define a grid pattern, the outer layers being selected from film and cloth wherein said cloth comprises warp yarns and fill yarns, wherein lines bisecting acute angles are substantially parallel to the direction of said fill yarns and said cross machine direction, with said scrim yarns supporting said fabric in the cross machine direction and in the fill and bias directions, and adhesive means between said outer layers for securing the layers together and holding said sets of scrim yarns in said intersecting configuration.
