摘要： The present invention relates to a method of manufacturing a cellulose product having a flat or non-flat product shape by a pressure moulding apparatus comprising a forming mould. The forming mould has a forming surface defining said product shape, The method comprises the steps of:
arranging a cellulose blank containing less than 45 weight percent water in said forming mould; heating said cellulose blank to a forming temperature in the range of 100°C to 200°C; and pressing said cellulose blank by means of said forming mould with a forming pressure acting on the cellulose blank across said forming surface, said forming pressure being in the range of 1 MPa to 100 MPa.-

摘要： A method for forming cellulose products in a forming mould system from an air-formed cellulose blank structure (2), where the forming mould system comprises one or more forming moulds (3). Each forming mould comprises a first mould part (3a) and a second mould part (3b) configured for cooperating with each other during the forming of the cellulose products. The method comprises the steps: providing the cellulose blank structure, and in the cellulose blank structure defining one or more product sections (2a) and a residual section (2b) surrounding or arranged in connection to the one or more product sections; compressing at least a portion of the residual section to a first degree of compression higher than a degree of compression of the one or more product sections; feeding the cellulose blank structure in a feeding direction to a forming position in the forming mould system, where in the forming position each product section is arranged between a corresponding first mould part and second mould part; forming the cellulose products from the cellulose blank structure between the first mould part and the second mould part by heating the cellulose blank structure to a forming temperature in the range of 100-300 °C; and pressing the cellulose blank structure with a forming pressure in the range of 1-100 MPa, preferably 4-20 MPa.
