    Abstract: An apparatus and method for cleaning a moving web of sheet material. The apparatus includes a Coanda nozzle having an elongated, curved foil and a slit for directing gas at a high rate of speed along the foil. The gas from the foil impacts a layer of air entrained by the web of sheet material flowing in an opposed direction. Impact occurs within a gap formed between the foil and the web which becomes increasingly restricted in the direction of movement of the web. The entrained layer of air is caused to reverse direction within the gap and is mixed with the gas from the nozzle under turbulent conditions to clean the web and remove particulate material such as dust therefrom.
