Title (EN) DEVICE AND METHOD FOR COMPACTING POWDER MATERIAL
(FR) DISPOSITIF ET PROCÉDÉ PERMETTANT DE COMPACTER UN MATÉRIAU EN POUDRE
Abstract: front page image
(EN)A device (100) for compacting a layer (M) of powder material, comprising a slidable transport surface (106) adapted to support and advance the layer (M) of powder material along a predefined direction of advancement (A), a slidable compacting surface (127) flexible and superimposed to the transport surface (106) and substantially slidable in the same direction of advancement (A), pressing means (130, 135) adapted to press said compacting surface (127) towards the transport surface (106) so as to press the layer (M) of powder material interposed therebetween, and means (170, 180, 185) for contrasting the expansion of the layer (M) of powder material downstream of the pressing means (130, 135), which are configured for pressing the compacting surface (127) towards the transport surface (106) with a differentiated pressure in the transverse direction with respect to the direction of advancement (A), said means (170, 180, 185) for contrasting the expansion being independent from the compacting surface.
(FR)L'invention concerne un dispositif (100) de compactage d'une couche (M) de matériau en poudre, le dispositif comportant une surface de transport coulissante (106) conçue pour supporter et faire avancer la couche (M) de matériau en poudre dans une direction d'avance prédéfinie (A), une surface de compactage coulissante (127) flexible et superposée sur la surface de transport (106) et sensiblement coulissante dans la même direction d'avance (A), un moyen de compression (130, 135) conçu pour comprimer ladite surface de compactage (127) vers la surface de transport (106) de manière à comprimer la couche (M) de matériau en poudre intercalée entre les deux, et des moyens (170, 180, 185) permettant de l'expansion de la couche (M) de matériau en poudre en aval du moyen compression (130, 135), qui sont configurés pour comprimer la surface de compactage (127) vers la surface de transport (106) avec une pression différenciée dans la direction transversale par rapport à la direction d'avance (A), lesdits moyens (170, 180, 185) permettant de s'opposer à l'expansion étant indépendants par rapport à la surface de compactage.
