Method for dry-forming cellulose products from a cellulose blank structure in a product forming unit. The product forming unit includes a blank dry-forming module and a pressing module. The cellulose blank structure is air-formed in the blank dry-forming module onto a forming wire. The pressing module includes one or more forming molds for forming the cellulose products from the cellulose blank structure in a pressing operation. The method includes arranging the forming wire in a stationary mode during the pressing operation.

Method for dry-forming cellulose products from a cellulose blank structure in a product forming unit and a product forming unit

A forming mould system () for forming a cellulose product () from an air-formed cellulose blank structure (), where the forming mould system () comprises a first mould part () and a second mould part (). The first mould part () and the second mould part () are configured for moving in relation to each other in a pressing direction (DP). The second mould part () comprises a forming cavity section () and an inlet section (), where the inlet section () is arranged in connection to the forming cavity section () and configured for facilitating displacement of the cellulose blank structure () into a forming cavity () of the forming cavity section (). The inlet section () comprises a transition surface () defining an inlet opening (), and the inlet opening () is having a tapered configuration towards the forming cavity (). The disclosure further relates to a method for forming a cellulose product () from an air-formed cellulose blank structure () in a forming mould system ().
