Title (EN) IMPROVED PROCESS FOR PRODUCING A MECHANICAL FASTENER AND A MECHANICAL FASTENER PRODUCED THEREBY
(FR) PROCEDE DE PRODUCTION D'ELEMENTS DE FIXATION MECANIQUE ET ELEMENTS DE FIXATION MECANIQUE AINSI OBTENUS
Abstract: front page image
(EN)The invention is an improved process for forming a mechanical fastening prong and the prongs (22) produced thereby. The prongs are produced by deposition of a heated, thermally sensitive material onto a substrate (24), which is transported at a differential velocity relative to the heated material being deposited to form the prongs. Also, the transported substrate (24) may be drawn away from the point of deposition at an angle ($g(g)). By varying the velocity differential between the substrate (24) and the heated, thermally sensitive material as it is deposited and by varying the angle between the substrate and the point of deposition of the heated thermally sensitive material, the fastening characteristics, particularly the shear strength, of the fastening system formed of these prongs (22) may be advantageously modified.
(FR)Procédé amélioré pour former des crochets de fixation mécanique et crochets ainsi obtenus. Les crochets sont produits par dépôt d'un matériau thermosensible chauffé sur un substrat (24), lequel est transporté à une vitesse différente par rapport à celle du matériau chauffé qui est déposé pour former les crochets. De plus, le substrat transporté peut être éloigné à un certain angle ($g(g)) du point de dépôt. En modifiant la différence de vitesse entre le substrat (24) et le matériau thermosensible chauffé lorsque ce dernier est déposé et en faisant varier l'angle entre le substrat et le point de dépôt du matériau thermosensible chauffé, on peut modifier avantageusement les caractéristiques de fixation, tout particulièrement la résistance au cisaillement, du système de fixation formé par ces crochets (22).
