Abstract

Method for forming a continuous paper coil of fibrous particles, starting with a suspension of fibrous particles with a concentration of at least twice the concentration of sediments of fibrous particles, and characterized by the combination of the following phases: the highly concentrated suspension is divided and emerges by means of several channels or openings arranged in parallel; thereafter the suspension jets pass at a high speed at least to a chamber in which the jets rejoin and deflect; then the circulation of the suspension is accelerated and diverted again; and finally the turbulence disintegrates in order to form an accumulated three-dimensional veil structure of fibrous particles before being deposited.
