    • The present invention concerns a forming box for use in dry forming of a mat of fibrous material, said forming box comprising a housing with an open bottom for providing direct access fort the fibres onto an underlying forming wire and a vacuum box underneath said forming wire; an inlet for supplying fibre material into the inside of the housing; a number of spike rollers are provided in two rows in the housing between the fibre inlet and the housing bottom, wherein an endless belt screen is provided inside the housing having an upper run between two rows of spike rollers and a lower run closer to the open bottom of the forming box. The endless belt screen which runs between two rows of spike rollers and the lower part of the forming box, ensures an even distribution of the fibres just as fibre lumps or oversized fibres are prevented from beinglaid down on the forming wire and retained on the belt screen in the forming box and transported away from the lower portion of the forming box and returned to the spike rollers for further disintegration. In a forming box according to the invention, using an endless belt screen as the sieve or fibre screen is self-cleaning since the oversized fibres are retained on one upper side of the lower run of the endless belt screen and released on lower side of the upper run of the endless belt screen because of the vacuum underneath the forming box and the forming wire.
