Abstract

Procédé pour la réalisation d'une bande continue d'un matériau de particules fibreuses à partir d'une suspension fortement concentrée, caractérisé en ce que ladite suspensio, sous la forme de plusieurs flux ou écoulements partiels parallèles, est amenée tangentiellement dans une chambre dont la section droite est choisie de façon à engendrer la rotation, ladite suspension étant ainsi entraînée en rotation dans cette chambre, et en ce qu'ensuite la suspension est évacuée de la chambre en déviant la direction de son mouvement d'un angle compris entre environ 90 degrés et 180 degrés .
