ABSTRACT:
The invention is directed to a headbox for a machine used in the production of a fiber material web from a fiber suspension. The headbox includes a bottom and a plurality of walls defining a main chamber. A slice beam, defining a width of the outlet channel, is pivotably connected to at least one of the walls and is disposed adjacent to the front wall. The slice beam and the bottom define an adjustable outlet channel therebetween. A support plate extends substantially across the width and is pivotably connected at opposing first and second edges thereof to each of the front wall and the slice beam. The support plate inhibits deflections of the slice beam along the width.
