Abstract
A textile machine suction device for dust and other pneumatically conveyable waste includes a separator chamber, a negative pressure line discharging waste into the separator chamber, a first filter screen in the separator chamber for separating the waste from an air stream and for collecting the waste, a second filter screen disposed in the separator chamber, and a negative pressure source acting upon the first and the second filter screens. The two filter screens are disposed adjacent one another in a constellation causing an increasing outflow of air through the second filter screen with increasing soiling and impermeability of the first filter screen to the air stream. The negative pressure line forms a rotating air stream in the separator chamber approximately parallel to the first filter screen for forcing the waste and in particular yarn waste into a motion stripping soiling from the first filter screen.
