Title:
2次元螺旋状繊維ウェブの生産方法
Document Type and Number:
Japanese Patent JP2007533868
Kind Code:
A
Abstract:
A transverse fiber sheet is lapped by being guided in a substantially radial direction back and forth along a path between circumferentially outer and inner edges of the sheet, with the transverse sheet being reversed at each end of its path, the width of the transverse sheet being narrowed between the outer circumferential edge and the inner circumferential edge, the transverse sheet being held in place as it is lapped. Substantially mutually parallel yarns or tows are pulled to form a helical longitudinal sheet of density per unit area that decreases between its outer edge and its inner edge. The transverse sheet and the helical longitudinal sheet are superposed and advance continuously in flat rotation, and they are assembled together to form a helical sheet which is removed.
