Abstract: A method and related apparatus for producing one or several products starting from a cellulose based material have been worked out. A layer of fluffy material (20), to which a glue liquid content (30) is associated, is introduced between opened mould parts (80, 81). The closure of the mould provides an internal cavity (70) substantially conform in shape to the product to be obtained which defines a cavity having a smaller volume than the sum of the volumes of the compressed cellulose material structure (20?) and the volume of the glue liquid content (30). The amount of glue liquid content (30) is chosen so as to completely moisten, during the step of pressing the mould parts (80, 81), the compressed cellulose material structure (20?).
