The invention is a refastenable mechanical fastening system, made of free formed prongs joined to an embossed or raised substrate (24). The prongs (22) taper and are nonperpendicularly oriented relative to the plane of the substrate. Each prong (22) 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 the embossed or raised portion (23) of a moving substrate (24), stretching the liquid material in a direction parallel to the plane of the embossed or raised substrate and severing the stretched material to form the distal end and engaging means of 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.
L'invention est un système de fixation mécanique refixable, constitué de dents à structure libre assemblées à un substrat (24) bosselé ou surélevé. Les dents (22) sont effilées et sont non perpendiculaires par rapport au plan du substrat. Chaque dent (22) possède un élément d'engagement faisant saillie latéralement à partir de la périphérie de la dent. Les dents à structure libre sont fabriquées par le procédé de dépôt de matière liquide sur la partie bosselée ou surélevée (23) d'un substrat mobile (24), et consistant à étirer la matière liquide dans un sens parallèle au plan du substrat bosselé ou surélevé, et à séparer la matière étirée pour former l'extrémité distale et l'élément d'engagement de la dent. On décrit également l'avantage d'utiliser ce système de fixation dans un article de fabrication, tel qu'un vêtement absorbant, jetable, notamment une couche pour bébé.
