Abstract
A method of applying curved leg elastics to absorbent garments involves stretching and wrapping an elastic ribbon about a curved side of a puck. A portion of the elastic ribbon is simultaneously folded onto a top surface of the puck. The puck is attached to a rotating device that rotates the puck into alignment with a substrate. The substrate is then bonded to the portion of the elastic ribbon in its stretched position on the puck, thereby forming a finished seam. The resulting absorbent garments have gasket-like leg openings with improved comfort and aesthetic appeal.
