  • Patent number: 5980646
    Abstract: A continuous web cleaner having two elongated manifolds, each having an elongated row of brushes attached to either side of the manifold with both manifolds being physically oriented such that they face each other. The manifolds are offset from one another so that a continuous paper web can pass in between and through the two elongated manifolds. Each manifold is coupled to an exhauster outside or inside the room which creates a vacuum to remove paper dust, chad and other contaminants from the paper web itself and any contaminants collected by the elongated rows of brushes. Static electrical charges are removed from both sides of the continuous paper web by elongated static eliminator bars mounted at the input and output of the apparatus, both below and above the paper web.
