Abstract (en)

Absorbent paper, from a cellulose pulp, has at least one embossed zone (A1,A2) with projections on one surface matching the honeycomb recesses on the other surface. The honeycomb has a polygonal shape, and there is at least one zone (B) which is not embossed. The honeycombs (101,102) are deployed along at least one alignment. Absorbent paper, from a cellulose pulp, has at least one embossed zone (A1,A2) with projections on one surface matching the honeycomb recesses on the other surface. The honeycomb has a polygonal shape, and there is at least one zone (B) which is not embossed. The honeycombs (101,102) are deployed along at least one alignment. The sides of the facing honeycombs define a bridge with straight edges in a longer length than the width. They span preferably two non-embossed zones separated by an embossed zone.

Disclosed is a cotton cellulose sheet comprising at least one first embossed area (A<sb>1</sb>, A<sb>2</sb>) with protrusions on one side and corresponding indentations on the other side. The indentations have an essentially polygon-shaped base. The inventive sheet comprises at least one second non-embossed area (B). According to the invention: - the indentations 101', 102' are arranged at least according to one alignment; - the sides facing two adjacent indentations define a bridge (P) with straight or substantially straight edges having a length L which is greater than the greatest width D thereof. One or several interlinked bridges define a path between preferably two second non-embossed areas (B) which are separated by at least one embossed area (A<sb>1</sb>, A<sb>2</sb>). The invention also relates to a cylinder for embossing such a sheet.

Abstract (fr)

La feuille d'ouate de cellulose comprend au moins une première zone gaufrée (A1, A2) avec des protubérances sur une face correspondant à des alvéoles sur l'autre face. Les alvéoles ont une base de forme sensiblement polygonale, et la feuille comprend au moins une deuxième zone non gaufrée (B). Selon l'invention : les alvéoles 101', 102' sont disposés selon au moins un alignement, les côtés en vis à vis de deux alvéoles adjacents définissent un pont (P) à bords rectilignes ou sensiblement rectilignes de longueur L supérieure à sa plus grande largeur D, ledit pont reliant préférentiellement deux secondes zones non gaufrées (B) séparées par au moins une première zone gaufrée (A1, A2). <IMAGE>
