A forming mould system and a method for forming a cellulose product in a forming mould system

A method for forming a cellulose product from an air-formed cellulose blank structure in a forming mould system, wherein the forming mould system comprises a first mould part and a second mould part, wherein the first mould part and the second mould part are movably arranged in relation to each other in a pressing direction (DP), wherein the second mould part comprises a forming cavity section and an inlet section, wherein the inlet section is arranged in connection to the forming cavity section and configured for facilitating displacement of the cellulose blank structure into a forming cavity of the forming cavity section, wherein the inlet section comprises a transition surface defining an inlet opening, wherein the inlet opening is having a tapered configuration towards the forming cavity, wherein the method comprises the steps:

• providing the air-formed cellulose blank structure, and feeding the cellulose blank structure to the forming mould system;
• arranging the cellulose blank structure in connection to the inlet section in a first configuration (C1) in a position between the first mould part and the second mould part;
• moving the first mould part and/or the second mould part in the pressing direction (DP), and displacing the cellulose blank structure into the forming cavity with the first mould part, and during the displacement of the cellulose blank structure controlling a shaping of the cellulose blank structure with the transition surface from the first configuration (C1) into a second configuration (C2), wherein the cellulose blank structure in the second configuration (C2) is shaped into a three-dimensional cellulose blank body;
• forming the cellulose product by heating the three-dimensional cellulose blank body to a forming temperature (TF) and pressing the three-dimensional cellulose blank body in the forming cavity between the first mould part and the second mould part with a forming pressure (PF).
