Abstract
A method for manufacturing fastener ears for absorbent articles and other garments includes the step of cutting a wave-shaped pattern along the longitudinal axis of an elongated strip of material. The wave-shaped cutting pattern is substantially centered along the strip and divides the strip into a first web and a second web. Each web has a series of ear shapes, with each ear shape having a wave crest portion. Each wave crest portion has a first edge with a convex curvature. The method also includes the step of cutting each of the ear shapes out of its respective web to form a plurality of fastener ears. A fastener ear formed by such method is also contemplated.
