<p>An improved process for making disposable diapers, and the like, having hook-and-loop fastening systems, and disposable diapers made by the improved process. The loop structure of the hook-and-loop fastening system used in this invention is substantially free of article attachment adhesive and comprises loop elements affixed to a support structure. The loop elements are deformed when the loop structure is wound onto a parent roll (51). At least a portion of the deformed loop elements (4') are restored to essentially their original, undeformed, state after the loop structure is unwound from the parent roll. The restoration is accomplished by contacting the loop elements (4') with a mechanical restoration device (52) which comprises either a brush or a scarfing surface. The brush preferably has a plurality of bristles having an average free length greater than about three times the average undeformed height of the loop elements and an average bending modulus less than the average modulus of elasticity of the loop elements. The scarfing surface preferably has an average roughness of at least about 500 RMS.</p> |
