ABSTRACT:
Air flow apparatus for a clothes dryer wherein a flexible wrap having sealing runners is supported in sliding engagement on the rotating drum to cover that portion of the perforated annulus that is not istantaneously aligned with the suction duct. The end of the wrap opposite the direction of rotation of the drum is resiliently held such as by springs such that the tension on the wrap and the pressure on the drum is self-adjusting and maintained substantially constant. Therefore, the sealing runners are maintained in substantially uniform and continuous contact against the drum to limit the air flow path from the drum so that substantially all of the exiting air passes into the suction duct.
