A headbox for delivering paper-making stock to the forming member of a paper-making machine comprises a perforated member for effecting continuous screening of the stock being delivered, means movable relatively to the perforated member for effecting removal from the surface of the perforated member of particles that are too large to pass through the perforations, and an outlet through which the removed particles are continuously rejected from the headbox. As shown, the headbox 40 extends across the full width of the machine and supplies stock downwards to the space between the converging wire-cloths 25 and 35. A cylindrical casing 160 has perforations through which the stock passes, and a rotary member 165 within it carries bars 169, of aerofoil section. These as they rotate cause alternating positive and negative pressure waves which travel around the casing, and dislodge from it any particles that are too large to pass through the perforations. The rotary member 165 tapers from one side to the other of the machine. Stock is fed into the interior of the casing 160 on that side of the machine on which lies the small end of the member 165, and excess stock carrying the removed particles emerges from the other end of the casing. The casing 160 may be formed from a band of sheet material arranged in a spirally wound fashion with its edges abutting and bonded together along spiral seams, and have perforations over its entire area.
