Abstract (en)
[origin: WO9004678A1] By means of a procedure for the manufacture of contour stable objects a fluidized fibre raw material is deposited on a moulding foundation through suction of a pulp of the fibre raw material on that foundation. For this purpose the foundation is applied with an easily drainable pulp created from the fluidized fibre raw material layer in such an amount and the suction is carried out controlled in such a way that on the foundation through suction a fibre raw material layer is deposited having such wall thickness that it substantially provides the desired contour stability of the object.
Abstract (fr)
Dans le procédé décrit, qui sert à la fabrication d'objets présentant des contours stables, un matériau brut fibreux fluidisé est disposé sur une base de moulage par aspiration d'une pulpe du matériau brut fibreux sur cette base. A cet effet, on applique sur la base une pulpe facilement drainée créée à partir de la couche de matériau brut fibreux fluidisé, dont la quantité et le réglage de l'aspiration sont prévus de sorte qu'il se dépose sur la base par aspiration une couche de matériau brut fibreux ayant une épaisseur de paroi assurant aux contours de l'objet la stabilité désirée.
