<p>A device for producing a multi-ply fibrous product (60) comprises an embossing roll (10; 10') with first and second embossing protrusions (16, 18, 19) on its outer circumferential surface (11) having at least two different heights in a radial direction, an anvil roll (14) cooperating with the embossing roll (10; 10'), an application roll (48) for coloured adhesive or ink arranged next to the embossing roll (10; 10') and a marrying roll (30) or another embossing roll running against the embossing roll (10; 10'), wherein the application roll (48) forms a negative gap (g) with the outer diameter of the embossing roll (10; 10'), and the negative gap (g) is exceeding the difference in heights of the first and second protrusions. The invention further relates to a method for producing a multi-ply fibrous product and a multi-ply fibrous product.</p> |
