    摘要： A method for forming cellulose products from an air-formed cellulose blank having a base and one or more forming moulds attached to the base which is arranged to rotate around a rotational axis, wherein each forming mould comprises a first mould part Wand a corresponding second mould part wherein during rotational movement of the base around the rotational axis each first mould part is arranged to engage with its corresponding second mould part in a pressing direction. The method comprises arranging the cellulose blank in a position between a first mould and the second mould forming the cellulose products in the rotary forming mould system, by applying a forming pressure between the first mould and its corresponding second mould through an engaging movement of the first mould in relation to its corresponding second mould in the pressing direction, wherein the forming moulds are rotating with the base around the rotational axis.

    摘要： 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.

    摘要： A method for producing a cellulose product from a multi-layer cellulose blank structure, wherein the method comprises the steps; forming the multi-layer cellulose blank structure from at least a first layer of dry-formed cellulose fibres and a second layer of a cellulose fibre web structure, through arranging the at least first layer and second layer in a superimposed relationship to each other and in the superimposed relationship arranging the at least first layer and second layer in contact with each other; arranging the multi-layer cellulose blank structure in a forming mould; heating the multi-layer cellulose blank structure to a forming temperature in the range of 100° C. to 300° C., and forming the cellulose product from the multi-layer cellulose blank structure in the forming mould, by pressing the heated multi-layer cellulose blank structure with an isostatic forming pressure of at least 1 MPa, preferably 4-20 MPa, wherein the multi-layer cellulose blank structure is shaped into a two-dimensional or three-dimensional fibre composite structure having a single-layer configuration.

    摘要： A cellulose product toggle pressing module for forming non-flat cellulose products from an air-formed cellulose blank structure. The toggle pressing module includes a toggle press including pressing member movably arranged in a pressing direction, a toggle-mechanism connected to the pressing member, a pressing actuator arrangement connected to the toggle-mechanism, and an electronic control system operatively connected to the pressing actuator arrangement. The toggle pressing module includes a forming mold including a moveable first mold part attached to the pressing member and a second mold part. The electronic control system is configured for controlling operation of the pressing actuator arrangement for driving the pressing member using the toggle-mechanism in the pressing direction and forming the non-flat cellulose product from the cellulose blank structure by pressing the first mold part against the second mold part. Furthermore, the toggle press is installed with the pressing direction of the pressing member arranged primarily in a horizontal direction.

    摘要： A product forming unit for manufacturing non-flat cellulose products from an air-formed cellulose blank structure (2). The product forming unit includes a blank dry-forming module with a moveable forming wire, a toggle pressing module with a toggle press and a forming mold, and an electronic control system operatively connected to the forming wire and the toggle press. The blank dry-forming module is configured for air-forming the cellulose blank structure onto the forming wire. The toggle press includes a pressing member movably arranged in a pressing direction, a toggle-mechanism drivingly connected to the pressing member, and a pressing actuator arrangement drivingly connected to the toggle-mechanism. The forming mold includes a moveable first mold part attached to the pressing member and a second mold part. The electronic control system is configured for controlling operation of the pressing actuator arrangement for performing pressing operations, which involves driving the pressing member in the pressing direction by the toggle-mechanism, and thereby forming the non-flat cellulose product from the air-formed cellulose blank structure by pressing the first mold part against the second mold part. The electronic control system is configured for intermittently feeding the forming wire between subsequent pressing operations.
