Abstract

L'invention concerne une bâche pour une carrosserie A d'un camion, en particulier pour la carrosserie A d'une remorque (1) d'une semi-remorque, comprenant une insertion (5) textile plane, conçue comme tissu à mailles, laquelle est enfoncée dans une matrice (12) à base de matière synthétique. Afin de fabriquer une telle bâche à un coût avantageux, de telle sorte qu'elle présente des propriétés d'utilisation optimales, l'invention prévoit que les ouvertures (0) de l'insertion (5), qui sont délimitées par les fils dormants (6a-6c) et les fils de trame (7a-7c), du tissu à mailles de l'insertion (5), sont pénétrées par de la matière synthétique de la matrice (12).
