Abstract

L'invention vise à augmenter la résistance à la flexion et à la torsion de la ligne de séparation entre un film de couverture d'un panneau de câblage flexible et une bande métallique, tout en maintenant l'aisance à la flexion et en minimisant l'accroissement des dimensions du panneau de câblage flexible. Selon l'invention, une pluralité de rangées de bandes métalliques (12b) formant un ruban sur le panneau de câblage flexible sont conçues pour avoir une largeur ou une épaisseur accrue seulement à proximité des lignes de séparation (B1, B2) à découvert d'un film de couverture (12a), et la longueur (H2) de la partie dont la largeur ou l'épaisseur est modifiée augmente progressivement de la rangée extérieure vers la rangée intérieure.
