Abstract
An improvement in a traveling pneumatic cleaner for vacuum collection of fiber waste from a textile mill room in the form of a filter disposed in a receptacle for separating fiber waste from an air current passing through the receptacle. The filter defines a surface of revolution, preferably taking the form of a substantially conical foraminous surface about a central axis of the receptacle, and so arranged relative to the receptacle that the air current will be directed around the filter and then through the same with the velocity of the air current being diminished and lowered as it passes through the filter. Optionally, the filtering may be augmented by a foam filter medium cooperating with the foraminous surface.
