Abstract

L'invention concerne une chaîne d'attaches configurée de telle sorte que des sections pliées de ruban (22) de rubans d'attaches (20, 20') sont pliées vers l'intérieur, les premières surfaces de ruban étant à l'intérieur, et de telle sorte que des sections de type tête de mise en prise (32) de rangées (30) d'éléments sont disposées de manière à faire saillie sur l'extérieur des rubans en provenance des sections pliées de ruban (22). Des sections de montage d'éléments (23, 23') des rubans d'attaches (20, 20') comportent des premières régions de ruban (24) qui sont en contact avec des sections inférieures de type pied (34) des rangées (30) d'éléments, et comportent aussi des secondes régions de ruban (25) qui renferment des sections de connexion (35) et des sections supérieures de type pied (33) des rangées (30) d'éléments et qui exposent les premières surfaces de ruban sur l'extérieur. Les sections, l'une supérieure et l'autre inférieure, de type pied (33, 34) des rangées (30) d'éléments sont cousues par des fils à coudre (38) sur les premières régions de ruban (24) et les secondes régions de ruban (25) des sections de montage d'éléments (23, 23'). Quand des rangées côté gauche et côté droit (30) d'éléments ont été mises en prise les uns par rapport aux autres, des bords latéraux de ruban se faisant mutuellement face (20a, 20a') des sections de montage d'éléments côté gauche et côté droit (23, 23') sont en contact les uns par rapport aux autres. Par conséquent, dans la chaîne d'attaches, les rangées entières (30) d'éléments sont dissimulées de manière stable par les sections de montage d'éléments (23, 23') sans l'utilisation de corps de recouvrement de sorte que les rangées (30) d'éléments ne peuvent pas être vues de l'extérieur. Ainsi, la configuration peut améliorer l'aspect de la chaîne d'attaches et peut entraîner les sections de montage d'éléments (23, 23') à ressembler à des objets tridimensionnels tels des bords perlés.
