The device comprises an essentially rigid smooth first cylinder (1) and an essentially rigid second cylinder 83), the latter having points (3P). the first and second cylinders rotate in opposite directions about respective axes of rotation (1A, 3A) and are pressed against each other, thus defining between themselves a lamination nip (5), through which said at least two layers are passed. There is also a pressure roller 87), with a surface (7A) that is less rigid than the first and second cylinders (1, 3), this roller interacting with the second cylinder and being pressed against it. The pressure roller forms with the second cylinder (3) an embossing nip (9) through which the layers (V1, V2) previously laminated in the lamination nip (5) are passed and in which they are embossed.
L'invention porte sur un dispositif doté d'un premier cylindre (1) essentiellement rigide et lisse et d'un second cylindre (3) essentiellement rigide, le premier cylindre présentant des points (3P). Le premier et le deuxième cylindre pivotent dans des sens opposés autour d'axes respectifs de rotation (1A, 3A) et sont comprimés l'un contre l'autre, ce qui leur permet de définir ensemble une zone de stratification (5) à travers laquelle au moins deux couches passent. Le dispositif comprend également un rouleau de pression (7) pourvu d'une surface (7A) qui est moins rigide que le premier et le second cylindre (1, 3). Ce rouleau interagit avec le second cylindre et est comprimé contre ce dernier. Le rouleau de pression forme une zone d'estampage (9) avec le second cylindre (3) à travers laquelle les couches (V1, V2) préalablement stratifiées dans la zone de stratification (5) passent et dans laquelle elles sont estampées.
