Abstract

La présente invention concerne un procédé et un appareil de moulage d'un matériau en feuille comprenant des nervures parallèles sur une surface. On utilise un moule comprenant des rainures ayant la forme des nervures et ces rainures sont uniformément remplies par un matériau de moulage sec en utilisant un dispositif de couchage comprenant un certain nombre de lames adjacentes dont les sommets sont parallèles et, de préférence, en contact avec la surface supérieure du moule. Le dispositif de couchage balaie la surface supérieure du moule et les lames répartissent et compriment le matériau de moulage dans les rainures du moule. L'invention est particulièrement utilisable pour mouler des matériaux à forte teneur en fibres qui peuvent seulement être difficilement comprimés avec une densité suffisante dans un moule.
