ABSTRACT In an apparatus for forming a non-woven, fibrous web, a device for making a uniform density dispersion of the fibers in an aqueous fiber slurry and depositing the dispersion onto a web former, while maintaining its integrity. The device includes a generally laterally divergent channel, in which the greatest depth of the flowing stream of fiber slurry is at its fiber slurry entry end, having rolls for uniformly dis- persing the fibers, rolls for uniformly spreading the dispersion laterally throughout the channel, and means in cooperation with the rolls for moving the dispersion to an exit end of the channel adjacent the web former. Preferably, the device is equipped with air doctors directed at the rolls for insuring the separation of the dispersion from each roll as it is moved to another roll.
