Zusammenfassung:	An embossing system is provided for embossing a web having a first embossing roll having embossing elements and a second embossing roll having embossing elements, wherein at feast a portion of the embossing elements of the first and second embossing rolls are substantially oriented in the cross- machine direction. The embossing roll may be crowned, may have alignment means, and may be provided with precision gearing. La présente invention concerne un système de gaufrage d'une bande; le système comprend un premier rouleau muni d'éléments d'embossage, et un second rouleau également muni d'éléments d'embossage, ou au moins une partie desdits éléments d'embossage du premier et du second rouleaux sont essentiellement orientés dans le sens transversal. Le rouleau d'embossage peut être bombé, peut comporter des dispositifs d'alignement et peut être muni d'engrenages de précision.
