Abstract: The invention relates to a method for manufacturing a sheet of paper tissue which is embossed by an embossing cylinder of which the surface is fitted at least in part with embossing elements. The elements include a frustoconical base portion and a tip portion. The method is characterized in that the tip segment includes a flat of which the area is less than 75% of the smaller cross-sectional area of the base. Preferably the area of the flat is less than 20% of the base cross-sectional area. The invention furthermore concerns a sheet thusly manufactured and to sheets made of several plies of which at least one is a ply of the invention.

Abstract: The invention relates to a sheet of paper which includes at least one decorative pattern (14, 16) which contrasts visually against the sheet's background (12) and which has a first series of generally truncated protrusions (22) projecting from one side (13) of the sheet and aligned in a design. In the invention, the sheet (10) includes a second series of protrusions associated with the first series (22) and of which each protrusion assumes the approximate form of a low wall projecting from a side (13) of the sheet and having a height which is less than the height of the protrusions (22) of the first series and of which each (24) bridges the two adjacent protrusions (22) of the first series to enhance the visual perception of the decorative unit (14, 16).

Abstract: Compound webs with improved absorption and pliancy are described. The compound web includes: (a) protrusions in each ply at a frequency greater than 10 protrusions/cm2 and with the surface of the peaks of the protrusions of each ply being greater than 5% of the surface of the ply, and (b) at least one of the plies being embossed in the form of an artistic pattern wherein the distances and the directions of an arbitrary protrusion relative to adjacent protrusions are varied. The pattern is selected in such a manner that at least 25% of the protrusions of the ply take part in effective bonding with the coinciding protrusions of the other ply and the total bonded surface of the protrusion peaks of the ply that take part in bonding is at least 15% of the total surface of the peaks of the protrusion of the ply regardless of the relative positions of the patterns of the two plies.

Abstract: The invention concerns an absorbing multi-layer web (10) of at least two layers (12, 14) each including at least one embossed ply (16, 18, 20) made of a creped absorbent paper, having an outer side forming the outer side of the multi-layer web and an inner side, the inner side of the first layer (12) including first and second protrusions (22) and (24) respectively, and the inner side of the second layer (14) including third protrusions (26) nesting between the protrusions (22, 24) of the first layer, the two layers (12, 14) being bonded to each other, characterized in that the first layer (12) is a double ply including of an inner ply (16) of which the inner side includes first and second protrusions (22A) and (24A) respectively, and an outer ply (18) of which the inner side includes first protrusions (22B) and second protrusion (24B). The tops of the protrusions (22A) and (22B) are bonded to each other but not the tops of the protrusions (24A) and (24B).
