Abstract
The present invention relates to a method for the combination of at least two plies of tissue paper without glue and by pressure marking, characterized in that it involves embossing at least one first ply according to an embossing design by passage between a first cylinder and a second cylinder covered externally with a rubber blanket, then combining at least one second ply with the first ply by causing both plies to pass between the first engraved steel cylinder of axis CC′ and at least one first series of small externally smooth coaxial cylinders of axis XX′. Both plies are then passed between the first cylinder and a second series of small externally smooth coaxial cylinders of axis YY′, the axes CC′, XX′; and YY′ being horizontal and parallel. The invention also includes the apparatus for carrying out the disclosed method.
