Abstract
A method of applying curved leg elastics to absorbent garments involves stretching and wrapping a pair of elastic ribbons about a first curved surface of a pair of disks. A portion of each of the elastic ribbons folds onto a second surface of each of the disks. The disks are rotated about a point off-center from a center point of the disks. The portions of the elastic ribbons on the second surfaces of the disks are rotated onto a substrate and bonded to the substrate in their stretched positions on the disks, thereby forming finished seams. The resulting absorbent garments have gasket-like leg openings with improved comfort and aesthetic appeal.
