Abstract

La présente invention concerne un procédé et une installation pour réaliser une nappe de matière particulaire (7) à partir d'au moins une couche de matière particulaire (9) sur une bande de moulage (8) circulant en continu au moyen d'au moins une tête de dispersion (1), s'ensuivant un rognage des bords longitudinaux (17) de la nappe de matière particulaire au moyen d'un dispositif de rognage (23) au cours de la compression de la nappe de matière particulaire (7) dans une presse (22) pour donner une plaque de matériau. Selon l'invention, la matière particulaire (9) est stockée dans un réservoir (2), dosée au moyen d'un dispositif de dosage (15), déversée sous la forme d'un flux de matière (24) sur une largeur (B1) transversale à la direction de production (11) et sur une longueur (L) dans la direction de production, avec un masse surfacique de dosage (DFG) sensiblement homogène, puis introduite dans la tête de dispersion (1) sensiblement dans la direction de déplacement (12) et dispersée sur la bande de moulage (8) de façon orientée ou non sur une largeur (B2) au moyen d'au moins un dispositif de dispersion (14). L'invention se caractérise en ce qu'une masse surfacique (FG) sensiblement inférieure à la masse surfacique moyenne de la nappe de matière particulaire (7) et/ou à la masse surfacique de dosage (DFG) est dispersée sur les bords longitudinaux (17) de la nappe de matière particulaire (7). La présente invention concerne également une nappe de matière particulaire à comprimer dans une presse. (1401).
