Abstract

L'invention concerne un dispositif de nouage (600) pour faisceau de câbles/filins pouvant comprendre : un support (610) ayant une première surface (620) et une deuxième surface (630) opposée à la première surface (620) ; et une zone d'adhérence (640) disposée sur une partie de la première surface (620) du support (610). La zone d'adhérence (640) contient une couche adhésive (642) et une couche de protection (644) recouvrant la couche adhésive (642) et le support (610) peut être fléchi pour former, au moyen de la couche adhésive (642) après le retrait de la couche de protection (644), une boucle pour faisceau de câbles/filins. Le dispositif de nouage (600) peut adhérer à lui-même après installation sur câble/filin, sans aucune colle maintenue sur le câble/filin lors du retrait du dispositif de nouage (600). Un tel dispositif de nouage (600) a un temps d'installation beaucoup plus court que la bande de laçage existante et, en même temps, le dispositif de nouage (600) est beaucoup moins coûteux.
