Abstract

Procedure for the manufacture of continuous layer of fibrous particles, preparing a suspension of said particles whose concentration is not less than twice the sedimentation concentration of the fibrous particles, said suspension then being forced to pass through certain limiting spaces, and diverted by elements baffles in order to create a turbulent flow that guarantees uniform distribution throughout the sheet to be manufactured, and finally reducing the turbulent flow before the suspension is deposited, characterized in that the degree of turbulence of the flow is gradually reduced, and its intensity is reduced. At the same time, it gradually increases in the series of successive restrictions, by distributing the flow coming from a limiting space among a plurality of new limiting spaces of smaller diameter, in order to prevent spherical bodies with a diameter greater than three times the average length. of each particle can pass through the being ie of limiting spaces, transforming the turbulent flow resulting in a flow of fibrous particles of consolidated structure in the form of a three-dimensional network, which retain liquid in their interstices before being deposited.
