ABSTRACT:
A sealing device is disclosed which is particularly useful in connection with an aperture in a partition wall through which a rotating drum extends. The sealing device may be used to seal one side of the wall from the other. The sealing device may find applicability to situations where different conditions are maintained on opposite sides of the partition wall. For example, the drum may be a washing machine drum in a hospital laundry, and the partition wall may separate an area where aseptic conditions are maintained from an area which is not aseptic.
