FIELD: pulp-and-paper industry. SUBSTANCE: method involves first stage of introducing material web into apparatus incorporating rupturing device including at least two rupturing mechanisms comprising pressure members with sides oriented substantially parallel and/or perpendicular to axis of symmetry extending through center of rupturing mechanisms, which are positioned with respect to one another so that pressure members of one rupturing mechanism are inserted into slots defined between two adjacent pressure members of other rupturing mechanism; at second stage, holding material between sides and subjecting to excessive expansion; at third stage, withdrawing from apparatus material with formed microruptures available on one side of material and extending only through part of its thickness. EFFECT: provision for obtaining of paper-base fabric and/or similar material possessing improved optical and/or holding properties and/or increased absorbing properties. 11 cl, 5 dwg |
