Abstract
At the slice region of a headbox of a papermaking machine, an upper lip is extended across the machine width above the area where the stock suspension is charged onto the forming wire. To the lip is secured a profiling member with a portion thereof being extendable into the throat of the stock passage. The member has spaced upstanding arms. Inwardly-facing coaxially-aligned bolting extends through each arm and the pair thereof support a rectangular open frame. A load is disposed within the frame so as to be spaced from any side thereof, being supported on each side by the bolting. A self-contained force couple may be generated against the load in the form of equal forces in opposite directions.
