  • Publication number: 20240075676
    Abstract: A method for forming cellulose products in a mould system from an air-formed cellulose blank structure, where the forming mould system comprises a first mould part and a second mould part. The method comprises the steps: providing the cellulose blank structure, and defining one or more product sections and a residual section; compressing at least a portion of the residual section to a first degree of compression higher than a degree of compression of the one or more product sections; feeding the cellulose blank structure in a feeding direction to a forming position in the forming mould system, where in the forming position each product section is arranged between a corresponding first mould part and second mould part; forming the cellulose products from the cellulose blank structure between the first mould part and the second mould part by heating the cellulose blank structure and pressing the cellulose blank structure.
