Abstract

Le ruban protecteur pour groupe de fils électriques de l'invention est équipé : de deux matériaux de gainage en bande (10, 11) qui sont disposés sur un même plan selon un intervalle dans la direction de la largeur du ruban, et qui possède une flexibilité de manière à permettre l'enroulement hélicoïdal d'un groupe de fils électriques ; d'un matériau amortisseur en bande (12) qui possède une épaisseur d'au moins deux fois celle des matériaux de gainage en bande, qui est positionné entre les matériaux de gainage en bande tout en faisant coïncider sa partie face de fond avec celle des matériaux de gainage en bande en un plan, et dont l'une et l'autre des parties face latérale sont mises en adhésion avec les matériaux de gainage en bande des deux côtés ; d'un matériau de gainage en bande pour protection de matériau amortisseur (13) qui possède une flexibilité de manière à permettre l'enroulement hélicoïdal d'un groupe de fils électriques, et qui est installé sur une partie face supérieure du matériau amortisseur en bande dans un état de mise en adhésion ; d'un film de couverture (14) qui est mis en adhésion sur une partie face supérieure des matériaux de gainage en bande et du matériau de gainage en bande pour protection de matériau amortisseur dans un état de non compression du matériau amortisseur en bande ; et de couches adhésives (15, 16) formées au moins sur la face inférieure des matériaux de gainage en bande.
