Apparatus and method for manufacturing a double-sided embossing fibrous
web and such double-sided web
Abstract:
A double-sided three dimensional embosssed web is provided by passing an uncured paper or plastic web (15), through a nip between an embossing roller (18) and a pressure roller (19), the pressure roller having a smooth and hard surface to create the effect of a double-sided three dimensional embossing on the web. Such double-sided embossing gives the web a good hand and feel and a good drapability, thereby making the method suitable for manufacturing cloth, curtains, diapers and other products which should feel soft and pleasant and which should have a good drapability comparable with that of knitwear and textiles. The embossed web has 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) are opposed by raised areas (26).
