CA 2175241

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).

L'invention concerne un appareil et un procédé de production d'une bande gaufrée tridimensionnelle double face. Une bande (15), de préférence un bande de plastique ou de papier non durcie, est acheminée sur la ligne de pincement entre un rouleau gaufreur (18) et un rouleau presseur (19). On a constaté avec surprise qu'il est possible de créer un effet de gaufrage tridimensionnel double face en utilisant un rouleau presseur (19) présentant une surface lisse et une surface dure. Ce type de gaufrage double face confère à la bande un toucher et un tombant de qualité, ce qui permet de l'utiliser pour la fabrication de tissus, rideaux, couches et autres produits devant être doux et agréables au toucher et présenter un bon tombant comparable à celui des tissus à mailles et des textiles. La bande gaufrée ainsi produite présente un gaufrage ou des impressions (24) sur deux surfaces comme une image spéculaire autour d'un plan de symétrie (23) passant au milieu de la bande (15). De même, les zones surélevées (26) sont également symétriques.
