PAPER MACHINE HEADBOX WITH ADJUSTABLE LOWER LIP Abstract of the Disclosure A headbox for a machine for the manufacture of paper from a web of paper pulp has an upper lip and a lower lip disposed below the upper lip and operatively associated with the upper lip to form an interior region between the lower lip and the upper lip and a discharge region. The shape of the lower lip, adjacent the discharge region, over which the web of paper pulp flows is adjustable. The shape may be adjusted by the rotation of a round, rotatable member disposed flush with the lower lip of the headbox or by the deformation of a deformable member provided at the discharge region.
