摘要： A filter box for textile machines, especially spinning machines, comprising a filter subdividing a box into a raw air chamber and a clean air chamber, and a respective inlet opening and outlet opening communicating or connected with the raw air chamber. A ventilator is connected at its suction side with the clean air chamber. The filter possesses a cylindrical form and the inlet opening is formed by an inlet connection extending approximately tangentially with respect to the filter, in order to produce a spin flow in the raw air chamber.

摘要： An apparatus for cleaning air charged with contaminants, especially fibers and dust, comprising a pre-separator and a dust filter arranged after the pre-separator. At least one movable suction nozzle is effective at the surface of the dust filter. The pre-separator, constructed as a body of rotation, possesses an inlet portion structured for producing a spin flow and a jacket portion structured as a sieve surface which is surrounded by a rotatably mounted filter drum of the dust filter. A cylindrical filter body of the filter drum has operatively associated therewith at the inner surface thereof the movable suction nozzle, and drive means are operatively connected with the suction nozzle and filter drum.
