Zusammenfassung:	A pressing module and method for forming cellulose products (1) from an air-formed cellulose blank structure (2), where the pressing module (PM) comprises a forming mould (3) with a first mould part (3a) and a second mould part (3b) configured for interacting with each other for forming the cellulose products (1) from the air-formed cellulose blank structure (2) in the forming mould (3). The first mould part (3a) and/or the second mould part (3b) are movably arranged relative to each other in a pressing direction (DP) parallel to a longitudinal direction (DLO) of the pressing module (PM). The first mould part (3a) and the second mould part (3b) are at least partly configured for being arranged in an overlapping relationship in the longitudinal direction (DLO) during forming of the cellulose products (1). The first mould part (3a) comprises a first mould part section (4a) and a second mould part section (4b) arranged in connection to the first mould part section (4a). The second mould part section (4b) is configured for being displaced relative to the first mould part section (4a) in a lateral direction (DLA) of the pressing module (PM) during forming of the cellulose products (1) in the forming mould (3). The first mould part section (4a) and the second mould part section (4b) are configured for applying a forming pressure (PF) onto the air-formed cellulose blank structure (2) in the range of 1-100 MPa, preferably in the range of 4-20 MPa, during a single pressing operation (OSP) upon forming of the cellulose products (1) in the forming mould (3).
