Abstract
L'invention concerne un procédé et un dispositif de séchage d'une nappe de fibres, ce procédé consistant à sécher la nappe de fibres (5) entre deux bandes serrées (1, 2) se déplaçant parallèlement dans le même sens et tournant autour de rouleaux (6a, 6b, 7a, 7b). La première bande (1) est chauffée au moyen d'une chambre de pression (9) et la seconde (2) est refroidie au moyen d'une chambre à eau (10). La nappe de fibres (5) est dirigée en même temps qu'un feutre ou une toile (3, 4) à travers une zone de séchage formée par les bandes (1, 2), de façon qu'un côté de la nappe de fibres soit en contact avec la surface de la première bande chauffée (1) et que le feutre ou la toile (3, 4) soit placé entre la nappe de fibres (5) et la seconde bande refroidie (2). La nappe de fibres (5) est étalée dans son sens transversal avant d'être dirigée dans le dispositif de séchage, une tension transversale étant appliquée sur cette nappe (5), de manière à obtenir une structure étirée appropriée, laquelle tension peut être fixée et conservée lors du passage de la nappe dans le dispositif de séchage.
