Abstract
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.
