Abstract

The invention relates to a method for producing a strip of absorbent, rollable cellulose fibre material (100) which is suitable for use in the hygiene sector. A fibre layer consisting of cellulose fibres is placed on a base layer (8) and pre-compressed to form a loose non-woven fabric which is introduced into a gap between a pair of calender rollers (6.1, 6.2) and which is used to produce a pattern of dotted or lined print areas (17) in which the fibres (1) are disposed in a random manner and are compressed against each other at a pressure ranging from 150 to 600 MPa, resulting in a non-solvent fusion of said fibres and the production of a strip of fibre material (100) with an imprinted pattern.
