A non-through air dried paper web and method of making such a paper web are disclosed. The paper web includes at least two regions of different density and at least two regions of different basis weight. In one embodiment, the paper web includes a relatively high basis weight continuous network region, a plurality of discrete, relatively low basis weight regions dispersed throughout the relatively high basis weight continuous network region, and a plurality of discrete, intermediate basis weight regions circumscribed by the relatively low basis weight regions.
L'invention concerne une feuille de papier séchée à l'air selon un processus non traversant, ainsi qu'un procédé de fabrication d'une telle feuille de papier, laquelle comprend au moins deux régions de densité différente et au moins deux régions de grammage différent. Dans un mode de réalisation, la feuille de papier comprend une région formant un réseau continu à grammage relativement élevé, plusieurs régions distinctes, à grammage relativement bas, dispersées dans le réseau à grammage relativement élevé, ainsi que plusieurs régions distinctes, à grammage intermédiaire, entourées par les régions à grammage relativement bas.
