ABSTRACT:
At the slice region of a headbox or the like of a paper or equivalent machine, there is a front support structure which has an elongated substantially horizontal lower region situated adjacent an upper lip of the slice. An elongated strip extends along this lower region of the front support structure and projects downwardly beyond the latter where the strip terminates in an elongated substantially horizontal free edge defining the upper lip of the slice. An elongated plate is situated in front of and adjacent the front support structure, extending horizontally across the latter throughout the entire width of the slice, and this plate carries structure for adjusting the strip. A pair of supporting blocks, wedges, or the like are carried by the front support structure and are respectively situated substantially at Besselian points of the plate while carrying the latter and transmitting substantially all reaction forces which are substantially parallel to the front support structure between the latter and the plate.
