A method for dry-forming a three-dimensional cellulose product from cellulose fibres in a product forming unit that includes a fibre transporting unit, a shaping unit including one or more shaping elements having a three-dimensional surface, and a forming mould M. The one or more shaping elements are arranged on a movable support structure. The method includes the steps: providing loose and separated cellulose fibres and feeding the loose and separated cellulose fibres to the one or more shaping elements by means of flow of air, and arranging the loose and separated cellulose fibres onto the one or more shaping elements, wherein the three-dimensional surfaces of the one or more shaping elements have a shape corresponding to or similar to a final shape of the cellulose product formed in the forming mould; dry-forming the cellulose product into a three-dimensional compressed fibre structure in a pressing operation by pressing and heating.
A method for dry-forming a three-dimensional cellulose product from cellulose fibres in a product forming unit, wherein the product forming unit comprises a fibre transporting unit, a shaping unit, and a forming mould,
A product forming unit configured for dry-forming a three-dimensional cellulose product from cellulose fibres, wherein the product forming unit comprises a fibre transporting unit, a shaping unit, and a forming mould,
A three-dimensional cellulose product comprising air-formed and compressed cellulose fibres, wherein the cellulose product comprises at least two air-formed three-dimensional bodies of cellulose fibres that are arranged in connection to each other in a slightly overlapping relationship in the forming mould, where less compacted overlapping sections of the three-dimensional bodies of cellulose fibres are attached to each other in the pressing operation.
