<p>An apparatus and a method for manufacture a double-sided three dimensional embossed web is provided. A web (15) is led through the nip between an embossing roller (18) and a pressure roller (19). The web (15) is preferably in a non-cured state and may be a paper or a plast web. If a pressure roller (19) having a smooth and hard surface is used, it has surprisingly created the effect of a double-sided three dimensional embossing. Such double-sided embossing gives the web a good hand and feel and a good drapability thereby making it suitable for manufacturing cloth, curtains, diapers and other products which should feel soft and pleasant and which should have a good drapability to be compared with that of knitwear and textiles. The embossed web would occur with the embossing or impressions (24) provided on two surfaces as a mirror image around a plane of symmetry (23) passing through the middle of the web (15). In the same way raised areas (26) would be opposed by raised areas (26).</p> |
