Abstract (en)
[origin: WO2015019166A1] A method for reduction of lateral powder waste of a layer of powder material advancing on a mobile conveyor surface, the strip of powder material having a transversal section with decreasing thickness diminishing also in accordance with the angle of friction of the powder exhibiting a section alike an isosceles trapezium, and two containing walls being provided for the powder layer, perpendicular to the sliding surface and parallel to the advancement direction thereof, the method comprising the following activities: positioning the containing walls internally of each strip of powder having a decreasing thickness, so as to divide each strip into two portions having a substantially identical section, and transferring the powder which during the advancing of the strip is external of the walls into the space afforded between the walls in proximity of the walls. The device for reducing the lateral waste of powder comprises two lateral containing walls 6 for the powder having an adjustable gauge, as well as means (5, 7) for transferring, during the advancing of the strip, the powder which is external of the -walls into the space afforded between the walls in proximity thereof.
