<p>A method for embossing a sheet of crêpe paper having at least one ply, wherein the sheet is engaged between two metal cylinders provided with projections and rotated by a per se known system such that they mesh with a clearance (e1) between the tips of the projections of one cylinder and the facing surface on the other cylinder, and a clearance (e2) between the sides of two adjacent projections. The method is characterized in that (e1) and (e2) are determined, transversely to the moving direction of the paper, in such a way that the ratio of (e1) to (e2) is between 0.8 and 1.</p> |
