The preheated pack of layers is put under vacuum in a vacuum assembly station (,) for the purpose of extracting the gas from the spaces separating the layers (,). After the gas has been extracted, the edge of the pack of layers, which is heid under vacuum, is mechanically compressed inside the vacuum box and is thus sealed. Finally, the pack of layers is brought to atmospheric pressure and its temperature further increased in a postheat channel (,).
