Abstract

See full text

A hook fastener member having rows of molded hook-shaped fastener elements that lie in planes aligned with the rows, with generally planar plate portions at the outermost ends of at least some of the fastener elements, the plate portions lying generally parallel to the base of the fastener member. The plate portions can enhance engagement of the hook fastener members with mating loop fastener members, particularly with low loft non-woven loop fastener members. A method of making fastener members is provided. Molten resin is extruded and applied to a molding roller, creating preforms. The outermost portions of at least some of the preforms are flattened, thereby forming generally plate shaped portions. Disposable absorbent garments advantageously incorporate the hook fastener members.
