Preformed cross-laid fabric
Abstract
Abstract A fabric comprising from about two to eight yarns per inch running in the transverse or cross direction of the fabric and a selvage along each longitudinal edge of the fabric. Each selvage comprises from about 10 to 30 warp yarns and has a width of from 1 inch to 3 inches. The warp yarns in the selvage being woven with the cross yarns and the warp yarns having a denier of from about 70 to 300. The fabric is made by drawing a plurality of selvage warp yarns through each side of a loom while maintaining the yarns under tension. As the warp yarns are drawn through the loom the cross yarns are woven with the warp yarns to form the selvage. As each cross yarn is woven the selvage is held in place. The selvage is released and the fabric moved forward and regripped and the next cross yarn woven, and so forth. After the cross yarns are woven to form the selvages, tension is applied to the fabric in the crosswise direction and the fabric rolled on a driven roll.
