Abstract

The invention is a refastenable mechanical fastening system including rows of female loops (22) joined to a substrate. The loops taper from the base (26) to the distal end (30) and are typically nonperpendicularly oriented relative to the plane of the substrate (24). The shanks (28) of each loop may also have an azimuthal angle relative to the machine direction of the substrate. Each loop includes an opening (32) for receiving a portion of the prong (34) of a male hook component. The loops are manufactured by the process of extruding liquid material through the apertures (56) of a depositing member onto a moving substrate (24) to form the base of the loop, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form a distal end which fuses with an adjacent amount of stretched material to form a loop. The advantageous usage of the fastening system (110) in an article of manufacture, such as a disposable absorbent article, and more specifically, a diaper (100) is also disclosed.
