The invention is a refastenable mechanical fastening system (20), made of free formed prongs (22) joined to a substrate (24). The prongs (22) taper and are nonperpendicularly oriented relative to the plane of the substrate (24). The prongs (22) also have an azimuthal angle relative to the machine direction of the substrate. Each prong has an engaging means (30) projecting laterally from the periphery of the prong (22). The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate to form the base of the prong, 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 allowing the prong to azimuthally angle. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent article specifically a diaper, is also disclosed.
L'invention consiste en un système (20) d'attache mécanique réattachable, constitué de crochets (22) formés libres, joints à un substrat (24). Lesdits crochets (22) sont coniques et orientés de manière non perpendiculaire par rapport au plan du substrat (24). Les crochets (22) présentent également un angle azimutal par rapport au sens de production du substrat. Chaque crochet (22) présente un moyen (30) de prise saillant latéralement de sa périphérie. Le procédé de production des crochets formés libres consiste à déposer une matière liquide sur un substrat mobile afin de former la base du crochet, à étirer la matière liquide dans une direction parallèle au plan du substrat, à détacher la matière étirée afin de former l'extrémité distale et le moyen de prise du crochet, et à laisser ledit crochet former un angle azimutal. L'invention concerne également l'utilisation avantageuse du système d'attache applicable à un article manufacturé tel qu'un article absorbant disposable, spécifiquement une couche.
