A through-air device includes a permeable roll having a hollow interior and mounted for rotation about a longitudinal axis. At least one divider is located in the hollow interior so as to define a plurality of roll channels within the roll, the roll channels being positioned side-by-side along the longitudinal axis. A first housing bounds a first portion of the roll, and a second housing bounds a second portion of the roll. At least one partition is located in the second housing so as to define a plurality of housing channels within the second housing. Each one of the housing channels is aligned with a corresponding one of the roll channels. The device further includes structure for individually controlling airflow through each pair of corresponding roll channels and housing channels.
Un dispositif à air traversant comprend un rouleau perméable à intérieur creux, monté pour pivoter autour d'un axe longitudinal. Au moins un séparateur est placé dans l'intérieur creux pour former dans le rouleau une pluralité de canaux de rouleau, en enfilade, le long de l'axe longitudinal. Un premier logement est relié à une première partie du rouleau, et un second logement est relié à une seconde partie du rouleau. Au moins une cloison est placée dans le second logement pour y former une pluralité de canaux. Chacun de ces canaux de logement est aligné sur un canal de rouleau correspondant. Par ailleurs, ce dispositif comprend une structure qui permet de réguler individuellement le flux d'air dans chaque paire de canaux de rouleau et de canaux de logement correspondants.
