FIELD: pulp-and-paper industry, in particular, manufacture of paper which may be used for hygienic and household purposes. ^ SUBSTANCE: paper sheet consists of at least two layers of creped cellulose wool, upper and lower layers, said layers having weight within the range of 10-40 g/m2. Upper layer is embossed and equipped with primary projections divided along lines defining therebetween cells with surface within 1-20 cm2. Upper layer has longitudinal length exceeding that of lower layer by at least 0.6%, preferably by 0.6-2%, and is connected with said lower layer through apexes of primary protrusions so that pads are defined within cells. Method involves unwinding first band of cellulose wool from main bobbin; performing embossments on roll for providing embossment in accordance with pattern including primary projections forming lines which define closed cells therebetween; unwinding second band of cellulose wool from main bobbin; applying second band onto first band and connecting both bands through apexes of primary projections; winding resultant doubled band onto cartridge while applying tensile force; differentiating both bands in the process of joining so that at rest state length of both layers differs by at least 0.6%, preferably 0.6-2%; cutting resultant roll into smaller rolls. ^ EFFECT: increased convexity effect for simulating textile product. ^ 10 cl, 3 dwg |
