| Zusammenfassung: | Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which has been provided in connection with impulse drying, at which the wet paper web (
10
) is passed through at least one press nip (
12
) comprising a rotatable roll (
13
) which is heated and that the paper web during the passage through the press nip is given a three-dimensional pattern of alternating raised and recessed portions either by means of a pattern wire, band or belt and/or by a pattern on the heated roll (
13
) and where the paper web (
10
) after said press nip (
12
) is led around an essential part of the periphery of the heated roll (
13
) in order to provide an additional drying of the paper web while this is still in contact with said three-dimensional pattern. |
