METHOD OF PRODUCING AN EXTENSIBLE PAPER HAVING A THREE-DIMENSIONAL PATTERN AND A PAPER PRODUCED BY THE METHOD

摘要

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.
