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.
