Abstract
A multiple biased structural fabric and a method for making the same, are disclosed. In a preferred embodiment, double biased structural farbic is produced using the novel method. Single biased fabric made up of structural yarns held together by secondary yarns is fed through a folding machine. The single biased fabric folded onto itself in the folding machine presents two layers of single biased fabric in the form of a double biased fabric. This fabric is then fed to a stitching machine. The stitching machine knits or sews the two layers of fabric together to produce the double biased fabric of the instant invention.
Claims10
A method of making a multi-layer non-woven structural fabric comprising the steps of:
- directing a layer of single biased structural fabric having at least two edges longitudinally from a feed end to an exit end, wherein said layer of fabric is comprised of a plurality of structural fibers oriented substantially parallel to each other and biased to said edges;
- leading said layer to a first affixing stage comprised of means for affixing said structural fibers in alignment;
- leading said layer from said first affixing stage into at least one folding stage wherein said layer is folded longitudinally from one said edge toward another to form a multiple biased fabric;
- leading said multiple biased fabric from said folding stage into a second affixing stage wherein said multiple biased fabric is affixed together to provide a single structural fabric being multiple biased.
