| 摘要 |
The disclosure relates to an apparatus for producing a web-shaped metal foil (13) from molten starting material. The apparatus includes a movable, cooled substrate (3) and a nozzle (4) discharging a short distance from the substrate, by means of which nozzle the molten material is disposed to be applied to the substrate for cooling, for the formation of the web-shaped foil. In order to ensure good contact between the molten material and the substrate, the apparatus has a space (9) disposed between the nozzle (4) and the substrate (3), the space being connected to a vacuum chamber (10) in order, with the aid of a vacuum established in the space (9), to suck the molten material towards the substrate at constant, sufficiently high pressure so as to displace interface layers of air accompanying the substrate. In one alternative embodiment, the apparatus may be provided with a space disposed between the nozzle (4) and the substrate (2), the space being communicable with a pressure chamber (instead of the above-mentioned vacuum chamber) in order to press, by means of pressure, the molten material supplied through the nozzle against the substrate. <IMAGE>
