A method and system (100) for producing a bonded air-laid blank (10). Natural fibers and a polymer binder are introduced into a forming head (110) and captured as an unbonded air-laid web (20) on an air- permeable conveyor (120) arranged in connection with an outlet (113) of the forming head (110). The unbonded air-laid web (20) is heated to at least partly melt the polymer binder and bind the natural fibers to form a bonded air-laid blank (10). Non-bonded natural fibers are removed from at least one main surface (12, 14) of the bonded air-laid blank (10) by at least one vacuum suction head (162, 164) of an inline vacuum suction system (160). The bonded air-laid blanks (10) produced by the method and system (100) generate less lint or dust in the form of non-bonded natural fibers.
