A multi-sided bellows cover (10) has panel sections (12, 14, 16, 18) formed of extruded plastic panels in which rigid wall sections (32) are connected at the fold lines by flexible web sections (34). The web sections (34) are integrally molded by extrusion with at least one adjacent wall section (32), and many serial wall sections alternating with web sections may be integrally co- extruded with one another (13, 14). Intermittently, a bead (36) of one of the flexible web sections of one of the panel sections is captured in a slot (38) of one of the rigid wall sections of another panel section.

Selon cette invention, une protection à soufflets à multiples côtés (10) possède des sections panneaux (12, 14, 16, 18) formées de panneaux de plastique extrudé dans lesquels des sections parois rigides (32) sont reliées au niveau des lignes de pliage par des sections feuilles obtenues en continu flexibles (34). Ces sections feuilles obtenues en continu (34) sont intégralement moulées par extrusion avec au moins une section paroi adjacente (32), et plusieurs sections parois en série étant alternées avec des sections feuilles obtenues en continu peuvent être intégralement co-extrudées les unes avec les autres. Par intermittence, un bord roulé (36) de l'une des sections de feuilles obtenues en continu flexibles de l'une des sections panneaux est emprisonné dans une fente (38) de l'une des sections parois rigides d'une autre section panneau.
