The cellulose product comprises at least a first ply of embossed cellulose material and a second ply of embossed cellulose material, glued together. The first ply comprises: a first series of embossing protuberances with a first height (H′1) and a top surface to which a glue is applied which bonds the first ply and the second ply to one another; a second series of micro-embossing protuberances with a second height (H′2) lower than the first height (H′1); a third series of micro-embossing protuberances with a third height (H′3) lower than the second height (H′2). The protuberances of the first series are distributed over areas of the first ply, where the micro-embossing protuberances of the second series and the micro-embossing protuberances of the third series are absent.
A cellulose product comprising at least a first ply of embossed cellulose material and a second ply of embossed cellulose material, glued together, wherein the first ply comprises:
Product according to one or more of the previous claims, wherein the protuberances of the second series and the protuberances of the third series are distributed alternately.
Product according to one or more of the previous claims, wherein the first height is between around 1.1 mm and around 2 mm.
Product according to one or more of the previous claims, wherein the second height is between around 0.25 mm and around 0.35 mm lower than the first height.
Product according to one or more of the previous claims, wherein said third height is between around 0.1 mm and around 0.3 mm lower than the second height.
Product according to one or more of the previous claims, wherein the fourth height (H′4) is between around 1.1 mm and around 2 mm.
Product according to one or more of the previous claims, wherein the fifth height is between around 0.25 mm and around 0.35 mm lower than the fourth height.
Product according to one or more of the previous claims, wherein said sixth height is between around 0.1 mm and around 0.3 mm lower than the fifth height.
An embossing roller for the production of a cellulose product, comprising:
Embossing roller according to one or more of the claims from 14 to 16, wherein the first height is between around 1.1 m and between 2 mm.
