Abstract

L'invention concerne une bande (S) pouvant être pliée pour présenter la forme d'une rainure, notamment pour la couverture d'un toit. Cette bande comporte une arête flexible (11) prévue sur le bord d'une zone centrale (10). Des éléments servant à la fixation côté toit sont prévus sur le côté extérieur de cette arête (11). La zone centrale (10) présente une zone médiane flexible (Z). L'invention vise à créer une bande stable une fois posée, résistant à l'usure et pouvant être enroulée. A cet effet, la zone centrale (10) forme une âme souple (12) revêtue d'une feuille métallique des deux côtés, et la zone flexible est constituée par des zones pliables (15) des feuilles métalliques (13), qui forment un creux de chaque côté de l'âme souple (12).
