Abstract: The invention relates to a method and an arrangement for producing a flow of stock in a moulding tank (1). In this, stock is pumped into the moulding tank (1) at the bottom (1a) and allowed to flow up over the brim (1b) thereof. During its rise in the moulding tank (1), the flow of stock pumped in is distributed by at least one grating placed essentially horizontally and provided with flow openings. An arrangement for performing the said method comprises a line (2a, 2b), connected to the moulding tank (1) and a machine vat for ready prepared stock, for delivering fresh stock to the moulding tank (1) by means of a pump (5) connecting with the line (2a, 2b). The line (2b) opens out in an area close to the bottom (1a) of the moulding tank (1) in such a way that an upwardly directed flow of stock is obtained. The pump (5) is adapted to deliver excess stock so that excess stock is allowed to flow over the brim (1b) of the moulding tank (1).

Abstract: The invention relates to a method and an arrangement for manufacturing a fiber product. The method and the process are characterized in that a first male mold (6) is immersed in stock in a molding tank (2a). By means of a vacuum, fibers are induced to form a fiber layer of predetermined thickness on the male mold (6). The male mold (6) is thereafter removed from the molding tank (2a) and a female mold (8) is brought under force against the male mold (6) in order to express the stock water, following which the fiber product (P) is transferred to the female mold (8). A second male mold (10) is brought under force against the female mold (8) so that the fiber is subjected to pressing in order to increase the dry solids content of the fiber product and give this a predetermined external structure, following which the fiber product (P) is released and subjected to final drying under the effect of microwave or IR radiation.
