METHOD OF AND MEANS FOR PAPERMAKING WITH HIGH CONSISTENCY FIBER SUSPENSIONS

摘要

Turbulence is generated within a headbox(10) nozzle passage(12) in a close adjacency to the slice opening(13) to assure thorough and substantially uniform dispersion of the fibers in a jet stream delivered to the forming area(15) on a travelling paper web forming surface(17). 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.
