The invention relates to a method for producing a vacuum insulation panel (12), wherein a film (5) is inserted into a cavity (7) of a molding tool (6) and an open-cell PUR mixture is applied. Protruding regions of the film are folded and the PUR mixture is completely surrounded by film. The molding tool closes, the PUR mixture foams and presses the film against the walls of the cavity. This results in the formation of an open-cell rigid PUR foam structure with a compact skin which is surrounded by film. A step of evacuating the open-cell (rigid) PUR foam structure creates a vacuum insulation panel. In order to improve the process integration and for efficient production of vacuum insulation panels, all the steps of the method can be carried out directly one after another.

A method and a device for producing fibre-reinforced plastic mouldings, using coated fibre strands. For the coating of the fibre strands, an air flow of ionised air is produced and guided through a Venturi nozzle. Powder from a storage container is taken by means of a screw conveyor and supplied to the Venturi nozzle, a flow of a powder-air mixture being present or forming behind the Venturi nozzle in the direction of flow. This stream is introduced into a chamber and fibre strands that are earthed or ionised unlike the powder are passed through the chamber and through the powder-air mixture flowing through the chamber, powder particles being deposited on the fibre strands. The fibre strands guided out of the chamber therefore have a coating, and the fibre strands coated in this way are supplied to a plasticising device of an injection moulding machine or an extrusion machine.
