Abstract (en)

[origin: WO2019234603A1] A method is described for producing a multi-ply cellulose tissue paper web material, comprising at least a first ply (V1) and a second ply (V2) bonded to each other. The first ply (V1) is made to pass between an embossing roller (11) and a first pressure roller (17). The first embossing roller (11) is provided with embossing protuberances (57; 59; 101; 103) distributed according to first annular bands on a lateral surface of the embossing roller (11), between which there are interposed second annular bands without embossing protuberances. The first ply (V1) is embossed along longitudinal embossing bands (53; 102), and calendered along longitudinal calendering bands (51; 104), as a result of the co-action of the embossing roller (11) with the pressure roller (17).
