  • Method of ensuring flatness of a vane in a headbox by means of a mounting arrangement, headbox with such a mounting arrangement, a mounting arrangement and vane therefor
    Patent number: 7166193
    Abstract: A method of ensuring the flatness of a vane that is mounted in a headbox by means of a mounting arrangement including engagement dowels for cooperation with a downstream support wall of a transverse groove, said vane being affected during operation by shearing forces from the stock and by retaining forces from the mounting arrangement. In accordance with the invention outer engagement dowels are mounted at the side edges of the vane to cooperate during a specific period of time, as the only engagement dowels with the downstream support wall in order to take up said shearing forces, whereby tensile stresses will arise in the downstream end portion of the vane in the cross machine direction.
