ABSTRACT:
An air blast dust removal machine has a jet of air projected from at least one slot-like nozzle inclined at an obtuse angle towards an oncoming 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 desposed on the opposite 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.
