ABSTRACT:
Improvements in the internal dividers of a papermaking headbox are provided by stiffening the dividers only in the cross-machine direction. These cross-machine stiffened dividers provide for a smooth and thin divider that is flexible in the machine direction and yet is strong and resists distortion, buckling or bending in the cross-machine direction.
