Abstract
L'invention concerne un panneau incurvé en matériau fibreux ondulé, comprenant deux feuilles de revêtement 56 et 56', et une feuille intermédiaire ondulée 58. Selon l'invention, la partie incurvée 60 du panneau est comprimée et a une épaisseur réduite par rapport à celle du restant du panneau. L'invention permet de former des panneaux comprenant des parties incurvees, ne comportant pas de plis sur leur face apparente
