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.

Abstract: A multi-cavity forming mould system for forming a plurality of discrete three-dimensional cellulose products from an air-formed cellulose blank structure. The forming mould system includes a first mould part and a second mould part arranged for cooperating with each other during forming of the cellulose products. The first mould part includes a plurality of first forming elements and the second mould part comprises a plurality of corresponding second forming elements movably arranged in relation to a base structure of the second mould part. The forming mould system is configured for establishing a plurality of forming cavities for the cellulose blank structure between each first forming element and corresponding second forming element during formation of the cellulose products.

Abstract: A method is provided for producing discrete three-dimensional cellulose products from an air-formed cellulose blank structure in a rotary forming mould system. The method includes providing an air-formed cellulose blank structure, wherein the cellulose blank structure is air-formed from cellulose fibres; transporting the air-formed cellulose blank structure to a the rotary forming mould system; feeding the air-formed cellulose blank structure to a position between a first mould part and a second mould part, and heating the air-formed cellulose blank structure; forming the three-dimensional cellulose products from the air-formed cellulose blank structure in the rotary forming mould system, by pressing the heated air-formed cellulose blank structure with a forming pressure.
