Abstract

L'invention concerne un dispositif de traitement (7) et un procédé de traitement pour une bande de matière sèche ou humide (2) provenant d'une matière fibreuse textile. Dans une chambre de séchage (13, 13'), la bande de matériau en mouvement est guidée dans un méandre (18) et traitée par un écoulement de gaz (16), l'écoulement de gaz (16) exerçant une pression d'un côté de la bande de matière et étant dirigé à travers la bande de matière (2). La bande de matière (2) est pressée et maintenue sur une section de méandre (30) suspendue au côté inférieur d'un moyen de transport (23, 25) d'un écoulement de gaz (16) dirigé vers le haut.
