Abstract
An embossing roll for producing fibrous products, has a structurized embossing surface suitable to run against an anvil roll. The structurized embossing surface includes male protrusions or female depressions starting from a base circumferential surface of the roll. The embossing pattern is characterized by the following features: the base areas of selected male protrusions or female depressions in the base circumferential surface are different; the heights or depths of selected male protrusions or selected female depressions in a radial direction of the roll and starting from the base circumferential surface are different; and the angles between sidewall sections and the adjacent base circumferential surface of selected male protrusions and/or female depressions are different.
Claims8
