A raw material (12) comprising a mixture of a natural fiber and a thermoplastic fiber is supplied to the surface of the rotating rotary body (11). The natural and thermoplastic fibers are scattered toward the carrying surface of the conveyor belt (15) by the rotational force of the rotary body (11). An air blower (14) may direct pressurized air to the scattered raw material (14) in order to further effect separation of the natural and thermoplastic fibers. Consequently, the natural fibers and the thermoplastic fibers are deposited such that the relative concentration of the natural fibers and the thermoplastic fibers gradually and seamlessly changes or varies across the thickness or depth of the resulting molded fiber material (50).
La présente invention concerne une matière première (12) comprenant un mélange constitué d'une fibre naturelle et d'une fibre thermoplastique, qui est appliquée à la surface d'un corps rotatif en rotation (11). Les fibres naturelles et thermoplastiques sont dispersées vers la surface de support d'une courroie de transport (15), au moyen de la force de rotation du corps rotatif (11). Une soufflerie (14) peut diriger de l'air pressurisé sur la matière première dispersée (12), afin d'effectuer la séparation des fibres naturelles et thermoplastiques. Les fibres naturelles et les fibres thermoplastiques sont ainsi déposées de façon que la concentration relative des fibres naturelles et des fibres thermoplastiques change ou varie progressivement et continuellement sur l'épaisseur ou la profondeur de la matière fibreuse moulée résultante (50).
