<p>of the Invention An air blast dust removal machine has a jet air projected from at least one alot-like nozzle inclined at an obtuse angle towards an on coming sheet material which is held to a moving permeable conveyor belt. The sheet material is held to the conveyor belt by at least one suction device disposed on the opposite side side of the conveyor belt as the sheet material passes adjacent the jet of air. A second conveyor belt holds the sheet material from its top side by a suction device, and an obtusely projected jet of air blasts dust from the bottom side of the sheet material.</p> |
