摘要： A mechanical fastener. A preferred embodiment of the invention provides a mechanical fastener including engaging stems having heads with demarcation lines. The present invention also provides a method of making a mechanical fastener that includes placing a layer of heated material on stem ends to soften the stem ends and deforming the softened stem ends into convex heads.

摘要： A method and apparatus for forming a mechanical fastener. A preferred embodiment of the method includes moving a substrate along a web path, where the substrate includes a first major surface and a plurality of stems extending from the first major surface of the substrate and each of the stems includes a stem end, radiantly heating the stem ends to form softened ends, and thereafter deforming the softened ends into convex heads with a deformable surface. A preferred embodiment of the apparatus includes a web conveyor, where the web conveyor defines a web path, a heating source located adjacent the web conveyor and a deformable surface located down the web path from the heating source, where the deformable surface includes a durometer hardness of greater than 10 Shore OO and less than 70 Shore A.

摘要： A mechanical fastener including a plurality of engaging stems located in unordered arrangements, which repeat on a substrate. A preferred embodiment of the invention provides a mechanical fastener with a plurality of repeating unordered arrangements, where the arrangements repeat in more than one direction. The unordered arrangements of the engaging stems allow pairs of the fasteners to interengage with themselves, or in other words, to self-mate. Additionally, the unordered arrangements of engaging stems allow the fasteners to interengage at any relative angular orientation with a relatively constant engagement force, and a relatively constant disengagement force regardless of their angular orientation. The unordered arrangements of engaging stems also allow pairs of fasteners to interengage at any relative planar position with a relatively constant engagement force and a relatively constant disengagement force regardless of their planar position.
