Abstract: A method for forming cellulose products (1) from an air-formed cellulose blank structure (2) in a rotary forming mould system (3), wherein the rotary forming mould system (3) comprises a base structure (4) and one or more forming moulds (5) attached to the base structure (4), wherein the base structure (4) is arranged to rotate around a rotational axis (AR) extending in an axial direction (DA), wherein each forming mould (5) comprises a first mould part (5a) and a corresponding second mould part (5b), wherein during rotational movement of the base structure (4) around the rotational axis (AR) each first mould part (5a) is arranged to engage with its corresponding second mould part (5b) in a pressing direction (DP), wherein the method comprises the steps; providing the air-formed cellulose blank structure (2); arranging the cellulose blank structure (2) in a position between a first mould part (5a) and its corresponding second mould part (5b); forming the cellulose products (1) from the cellulose blank structure (2) in the rotary forming mould system (3), by applying a forming pressure (PF) on the cellulose blank structure (2) between the first mould part (5a) and its corresponding second mould part (5b) through an engaging movement of the first mould part (5a) in relation to its corresponding second mould part (5b) in the pressing direction (DP), wherein during forming the one or more forming moulds (5) are rotating with the base structure (4) around the rotational axis (AR).
