Abstract

L'invention concerne un dispositif de traitement en traversée d'une bande perméable au gaz d'un matériau textile, en particulier de séchage d'étoffes tissées ou non tissées. Ledit dispositif est constitué d'un tambour perforé (1) monté de manière à pouvoir tourner, pouvant être relié à un dispositif de production de dépression et doté d'une surface circonférentielle extérieure portant la bande de matériau, perméable et constituée d'une tôle dans laquelle sont pratiquées une pluralité d'ouvertures (4). Selon l'invention, les ouvertures (4) présentent une longueur (IK) traversée supérieure à l'épaisseur (D) de la tôle (2) du tambour.
