ABSTRACT:
Turbulence is generated within a headbox nozzle passage in such close adjacency to the slice opening as to assure thorough and substantially uniform dispersion of the fibers in a jet stream delivered to the forming area on a travelling paper web forming surface. Substantial suppression of turbulence in the jet stream is effected without interferring with the substantial uniformity of fiber dispersion in the suspension as delivered to the forming surface.
