  • Patent number: 10513075
    Abstract: Illustrated and described are a method and a device for laminating a profiled fibre moulding with a thermoplastic film. The film is laminated onto a surface of the fibre moulding to be coated by heat and differential pressure. To improve the lamination of the fibre moulding and to achieve uniform lamination thicknesses over the entire fibre moulding, the method includes the following steps: fixing at least an edge of the fed film to a base plate, heating the film, deforming the film via a moulding tool, feeding the fibre moulding, joining the fibre moulding to the pre-formed film, and removing the laminated fibre moulding.

  • Patent number: 10309062
    Abstract: A method and a device for manufacturing a fiber molding for drinks packaging containers having an improved structure and surface quality. The method includes the following steps: dipping of a forming wire arranged on a toolholder into a pulp slurry, lifting of the toolholder in order to move the covered forming wire completely out of the pulp slurry, compressing of the fiber material in an area of the circumferential edge of the forming wire through inflating of a circumferential collar, relaxing of the pressure in the collar, and removing of the fiber molding. A device for manufacturing of a fiber molding is also provided.
