ABSTRACT:
Apparatus for removing dust from the flat surfaces of stationary or moving sheets, webs, plates or similar objects has a unit which converts a low-pressure laminar air stream into a pulsating air stream. The pulsating stream contacts the surface of an object simultaneously with ultrasonic radiation. The direction of flow of the pulsating air stream, which can be ionized, may be parallel with or at right angles to the direction of propagation of ultrasonic radiation.
