ABSTRACT:
In a headbox of slender profile having a load bearing structure extending in the cross machine direction located on one side of the headbox rectifier section, load transfer partitions reaching across the depth of the rectifier section connect one wall of the section to the opposite wall in load transfer relation, to transfer pressure loading there-across, so as to maintain the rectifier section in substantially undeformed condition during operation.
