A device is provided to produce an embossed multi-ply material, comprising: a first embossing-laminating unit (3) comprising a first embossing cylinder (5) equipped with first projections (5P) defining a first pattern, a first pressure roller (7) cooperating with said first embossing cylinder (5), a first laminating roller (9) and a first glue dispenser (11), disposed between said first pressure roller (7) and said frst laminating roller (9); an embossing unit comprising at least a second embossing cylinder (25) provided with second projections (25P) defining a second pattern and a second pressure roller (27) cooperating with said second embossing cylinder (25); a first path (P1) through said first embossing-laminating unit (3); a second path (P2) for at least a second ply (V2) towards and through said second embossing unit (23); a third path (P3) for said third ply (V3).
A multi-ply web material (N), comprising at least three plies joined to one another by gluing, wherein:
Material as claimed in one or more of the previous claims, wherein said first and said second decorative elements are distributed randomly with respect to each other.
Material as claimed in one or more of the previous claims, wherein said first ply (V1) has a background embossing (P2).
Material as claimed in one or more of the previous claims, wherein said second ply (V2) has a background embossing (P4).
Material as claimed in one or more of the previous claims, wherein at least some of the protuberances (P3) defining said second decorative elements (E2) are flattened at the level of the respective protuberances (P1) defining said first decorative elements (E1).
Material as claimed in one or more of the previous claims, wherein said third ply (V3) is devoid of embossing.
Material as claimed in one or more of the previous claims, wherein said third ply (V3) is colored.
Material as claimed in one or more of the previous claims, wherein said third ply (V3) has a printed pattern.
Material as claimed in one or more of the previous claims, wherein one or more of said first, second and third plies are composed of two or more layers (S1, S2).
Material as claimed in one or more of the previous claims, wherein said at least one third ply (V3), is glued to the second ply by lamination at the protuberances forming said second decorative elements (E2).
Material as claimed in one or more of the previous claims, wherein said first and second glue are chromatically different from each other.
Material as claimed in one or more of the previous claims, made up in a roll.
Method for the production of a multi-ply web material comprising the phases of:
Method as claimed in one or more of claims 25 to 31, wherein said first ply (V1) is embossed between a first pressure roller (7) and a first embossing cylinder (5) having projections (5P) corresponding to the protuberances (P1) forming said first decorative elements (E1), and said second ply (V2) is joined to said first ply (V1) laminating said first ply (V1) and said second ply (V2) between the first embossing cylinder (5) and a first laminating roller (9), with said at least one third ply (V3) interposed between the first and the second ply.
Device for the production of embossed multi-ply web material, comprising:
