Abstract

L'invention concerne un procédé pour déshydrater des suspensions à base de solides et de liquides, notamment des suspensions à base de fibres. La suspension est déshydratée entre deux bandes (4, 5), une zone de déshydratation se présentant sous forme de zone cunéiforme. L'invention se caractérise principalement en ce qu'au début de la partie cunéiforme, les rouleaux supérieurs et/ou inférieurs se présentent sous forme de rouleaux de serrage.
