DEVICE AND METHOD FOR COUPLING TWO OR MORE PAPER WEBS OR PLIES BY GLUING
Abstract:
Device for coupling two or more paper webs or plies by gluing, 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 (N1, N2; N3) onto each other determining their coupling. The said gluing means comprise at least one body (1) provided with corresponding reliefs (R1) which apply the glue on predetermined gluing zones or areas of a paper ply (N2) advancing along a predetermined direction (F2) and said pressure means comprise a presser (3) which is located downstream of the said gluing means with respect to the said direction (F2) and is provided with corresponding reliefs (R3) which exert, on said paper plies (N1, N2; N3), a localized pressure on pressure zones or areas interfering with said gluing zones or areas, so that the glue passes through the glued ply (N2) only in correspondence of said pressure areas or zones.
