Zusammenfassung:A method for dry-forming a cellulose product from cellulose fibres in a product forming unit and product forming unit, where the product forming unit comprises at least one shaping element and a forming mould. Loose and separated cellulose fibres are provided and the loose and separated cellulose fibres are fed into a flow of air for transporting the cellulose fibres to the at least one shaping element by means of the flow of air as carrying medium for the cellulose fibres; arranging the loose and separated cellulose fibres onto a three-dimensional surface of the at least one shaping element by means of the flow of airfor air-forming at least one three-dimensional body of cellulose fibres; dry-forming the cellulose product into a three-dimensional compressed fibre structure by pressing and heating at least one three-dimensional body of cellulose fibres in a forming mould with a forming pressure in the range of 1-600 MPa and with a forming temperature in the range of 60-300 °C
