CA 2736770

A support member such as a belt or sleeve includes a topographical pattern on its sheet contact side. A plurality of land areas, corresponding depressions, through voids, and/or groove areas are formed on the top surface of the support member to produce the topographical pattern. The land areas, corresponding depressions, through voids, and/or groove areas may be formed by graving, cutting, etching, embossing, mechanical perforation or a combination thereof. The improved belt or sleeve imparts de-sired physical characteristics, such as bulk, appearance, texture, absorbency, strength, and hand to a nonwoven product produced thereon.

L'invention concerne un élément de support, tel qu'une bande ou un manchon, comprenant un motif topographique sur sa face de contact avec les feuilles. Une pluralité de zones en plateau, des cuvettes correspondantes, des évidements débouchants et / ou des zones de rainures sont formés sur la surface supérieure de l'élément de support pour donner le motif topographique. Les zones en plateau, les cuvettes correspondantes, les évidements débouchants et / ou les zones de rainures peuvent être formés par gravure, par coupe, par attaque chimique, par estampage, par perforation mécanique ou par une combinaison de celles-ci. La bande ou le manchon amélioré(e) confère des caractéristiques physiques souhaitées, comme un volume, un aspect, une texture, une capacité d'absorption, une résistance et un toucher, à un produit non tissé élaboré sur ladite bande ou ledit manchon.
