3d embossing

An embossing roll for producing fibrous products comprising:

• a structurized embossing surface suitable to run against an anvil roll, the structurized embossing surface comprising male protrusions or female depressions starting from a base circumferential surface of the roll;
• the embossing pattern having the following features:
• base areas of a plurality of male protrusions or a plurality of female depressions in the base circumferential surface are different;
• heights or depths of the plurality of male protrusions or the plurality of female depressions in a radial direction of the roll and starting from the base circumferential surface are different;
• angles between sidewall sections and the adjacent base circumferential surface of the plurality of male protrusions and/or female depressions are different;
• at least one male protrusion or female depression has sidewalls with at least two different slope angles between sidewall sections and the adjacent base surface;
• and
• a plurality of angles between side wall sections of male protrusions or female depressions and a normal to an adjacent base surface exceed 30°.
