Method for transporting a cellulose blank structure via a buffering module and buffering module

A buffering module for buffering an air-formed cellulose blank structure, wherein the buffering module is configured for being arranged in connection to a forming mould configured for dry-forming cellulose products from the cellulose blank structure,

• wherein the buffering module comprises a first endless belt unit, a second endless belt unit, and a third endless belt unit,
• wherein the second endless belt unit is arranged in-between and in a longitudinal overlapping relationship to the first endless belt unit and the third endless belt unit, wherein the second endless belt unit is movably arranged relative to the first endless belt unit and the third endless belt unit, wherein the buffering module is configured for continuously feeding the cellulose blank structure on the first endless belt unit in a first feeding direction, and redirecting the cellulose blank structure to the second endless belt unit;
• wherein the buffering module is configured for feeding the cellulose blank structure on the second endless belt unit in a second feeding direction being at least partly opposite the first feeding direction, wherein the second endless belt unit is configured for being alternatingly longitudinally moved in opposite directions relative to the first endless belt unit and the third endless belt unit, and redirecting the cellulose blank structure to the third endless belt unit;
• wherein the buffering module is configured for intermittently feeding the cellulose blank structure on the third endless belt unit in a third feeding direction at least partly coinciding with the first feeding direction;
• wherein the buffering module comprises a second layer application unit arranged in connection to the second endless belt unit, wherein the second layer application unit is configured for applying one or more second material layers to the cellulose blank structure.
