Abstract: 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 patterned wire, band or belt and/or by a pattern on the heated roll (13) and where said pattern is pressed into the paper web against a counter means (11, 14). The wet paper web before said press nip is exerted to a creping- or other compacting procedure which foreshortens the length of the paper web. The invention also refers to a paper produced by the method, said paper having a high extensibility.

Abstract: Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which is given the paper in connection with impulse drying. The paper web has a varying material composition as seen in its thickness direction, so that it at least in an outer layer contains an amount of a material that softens, melts or hardens in the temperature interval 100-400° C. or in some other way contributes in stabilizing the pattern structure that has been given the paper. It is further referred to an impulse dried paper produced according to the method.

Abstract: Method of producing an impulse dried paper having a three-dimensional pattern of alternating raised and recessed portions, which have been provided in connection with impulse drying, at which the wet paper web (10) is passed through at least two press nips (12a,b), each comprising a rotatable heated roll (13a,b) which is heated and that the paper web during the passage through the press nips is given a three-dimensional pattern of alternating raised and recessed portions either by means of a patterned wire (11'), -band or belt and/or by a pattern on the heated roll (13a,b).
