<p>Device for gluing two or more paper webs or plies, comprising gluing means destined to apply glue to a paper ply (N2) and pressure means which are located downstream of said gluing means and press more paper plies (Nl, N2; N3) onto each other determining their coupling. The said gluing means comprise at least one body (1) provided with corresponding reliefs (Rl) which apply the glue on predetermined gluing zones or areas of a paper ply (N2) advancing along a predetermined direction ( F2 ) and the said at least one gluing body (1) is the final roller of a gluing unit (C).</p> |
