Abstract: An apparatus for the production of a paper web, includes: a first embossing unit (1) with a first embossing cylinder (2) and a corresponding counter-cylinder (3) for embossing a first paper ply (4); a second embossing unit (5) with a second embossing cylinder (6) and a corresponding counter-cylinder (7) for embossing a second paper ply (8), such that, once embossed, the plies have a series of oppositely oriented reliefs (R4, R8), the embossing units (1, 5) being synchronized so that the reliefs are nested into each other; a sizing unit (1C, 2C, 3C) associated with the first embossing cylinder (2) to distribute a predetermined amount of glue on the side of the second ply (8) opposed to that from which the respective reliefs (R8) emerge; a structure (11) for joining to each other the plies (4, 8) exiting from the apparatus.
