Abstract:

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.
