Refastenable mechanical fastening system
First Claim
1. An article having a machine direction and a cross-machine direction comprising:
- a substrate; and
a fastening system for attaching to a complimentary receiving surface, said fastening system comprising a multiplicity of prongs, each said prong comprising;
a shank joined to said substrate at a base, said shank having a proximal end contiguous with said base and projecting outwardly from said substrate, said shank being nonperpendicularly oriented relative to the plane of said substrate, said shank further having an azimuthal angle between about 20° and
about 160°
; and
an engaging means joined to said shank and projecting laterally beyond the periphery of said shank.

Abstract
The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. The prongs also have an azimuthal angle relative to the machine direction of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate, severing the stretched material to form the distal end and engaging means of the prong, and imparting an azimuthal angle to the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper, is also disclosed.
