Abstract

Improvements made to head box devices for supplying paper pulp to a paper machine, a box comprising a cut chamber directing the flow of paper pulp to a cut and having a plurality of flow suppressing elements, projecting from a perforated plate located upstream towards the cut located downstream, which define a plurality of channels generally converging in the flow direction of the paste, characterized in that the flow or flow suppression elements are woven and/or flexible members pleats (25, 32, 36), which float freely in the cutting chamber (12) and which converge with a relatively narrow separation at their discharge ends.
