Abstract
The invention relates to methods and systems for producing a moulded product from a raw material comprising cellulose fibres, products made using the systems and methods, and liquid moulding agents for use in such systems and methods.
Claims23
System for producing a moulded product from dry laid cellulose fibre comprising
- a fibrous raw material supporting frame (2) for supporting one or more rolls (31-3n) of fibrous raw material (5) comprising cellulose fibres,
- a raw material transport system (7) for transporting the raw material to a milling device (9) for converting the raw material into cellulose fibres and cellulose fluff (11),
- a forming arrangement (13) for dry laying the cellulose fibres and cellulose fluff into a web of fibres (15),
- a web transport system (17) for transporting the web of fibres to a blank forming machine (19) for forming from the web and removing from the web the blanks (21) intended to form the finished moulded product (36),
- a blank transport system (23) for transporting blanks towards, and into, one or more, moulds (25) in a moulding device (27) comprising one or more mould(s) and pressure-applying means (29) for applying pressure to the blanks (21) in the mould(s) (25),
- a moulded product removing and transporting device (35) for removing moulded products (36) from the moulds, and a control system (37) for controlling the system for producing moulded products,
- characterised in that:
- a) after the blank forming machine (19) and before the blank transport system (23), a liquid moulding agent applying system (31) is arranged for supplying and applying a liquid moulding agent (33) consisting of an aqueous solution of mould entry aiding agent and/or mould release agent to the blanks (21) before they enter the mould(s) (25), or
- b) after the forming arrangement (13) and before the blank forming machine (19), a liquid moulding agent applying system (31′) is arranged for applying a liquid moulding agent (33) consisting of an aqueous solution of mould entry aiding agent and/or mould release agent to the web (15).
