The description relates to a device for embossing and laminating a multiple-web web material, comprising: a first and a second embossing cylinder (1, 3), provided with tips (1P, 3P), said two embossing cylinders being arranged with parallel and adjacent axes so as to form a nip (G) between them; a pair of pressure rolls (5, 7), each of which cooperates with one of the embossing cylinders; an adhesive applicator (17) associated with the first embossing cylinder; and a laminating roll (13) arranged downstream of the nip (G) between the embossing cylinders (1, 3) and cooperating with the first embossing cylinder (1). It is also envisaged that the planes (P3, P5) containing the axis (1A, 3A) of each embossing cylinder (1, 3) and the axis (5A, 7A) of the corresponding pressure roll (5, 7) are both inclined with respect to the plane (P2) containing the axes (1A, 3A) of the embossing cylinders at an angle ( alpha , alpha ') different from 0 DEG and 90 DEG ; and that the angle formed by the plane (P3) containing the axis (1A) of the first embossing cylinder (1) and the axis (5A) of respective pressure roll (5) with the plane (P2) containing the axes (1A, 3A) of the two embossing cylinders (1, 3) and directed towards said nip is greater than 90 DEG . Moreover, the two embossing cylinders (1, 3) may be phase-synchronized with each other so as to achieve operation using the "tip-to-tip" or "nested" technique. |
