Method for edge-forming cellulose products in a forming mould system, and a forming mould system for forming edges of cellulose products

A method for edge-forming cellulose products in a forming mould system (S), wherein the forming mould system (S) is adapted for forming the cellulose products from an air-formed cellulose blank structure, wherein the forming mould system (S) comprises a first mould part and a second mould part arranged for cooperating with each other, wherein the first mould part comprises an edge-forming device with a protruding element configured for compacting and separating fibres of the cellulose blank structure, wherein the edge-forming device is movably arranged in relation to a base structure of the first mould part, wherein the edge-forming device is adapted for interacting with a pressure member arranged in the base structure, wherein the method comprises the steps:

• providing the air-formed cellulose blank structure, and arranging the cellulose blank structure between the first mould part and the second mould part;
• forming a compacted edge structure of the cellulose products by separating fibres of the cellulose blank structure with the protruding element, applying an edge-forming temperature (TEF) onto the cellulose blank structure, and compacting the cellulose blank structure by applying an edge-forming pressure (PEF) by means of the pressure member onto the cellulose blank structure between the protruding element and the second mould part.
