A pressing roller (10) for the processing of web paper material, in particular of the type used in cooperation with an engraving roller (G1) for the bonding of two or more embossed plies of web paper material, comprises a cylindrical pressure surface (11) defined by a plurality of annular resilient pressure bodies (15) of rubber material that have a high surface hardness which allows to avoid the effect of double embossing and at the same time have a high elastic yielding which allows to obtain adequate nip also with relatively low contact pressures.

A method for production of a female embossing tool intended for embossing a sheet element: provide a female embossing tool with an outer layer made of a material with shape-memory type properties, and the outer face of the layer has no recesses; provide a male embossing tool with an outer face with at least one protuberance corresponding to at least one desired embossing relief that is to be formed on the sheet element after embossing; and cooperation of the male embossing tool with the female embossing tool such that the outer layer of the female embossing tool undergoes a plastic deformation which creates at least one recess of a shape complementary to the protuberance(s) of the male embossing tool.

An anvil is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.

A method for production of a female embossing tool (6) intended for embossing a sheet element (60): provide a female embossing tool (6) with an outer layer (44) made of a material with shape-memory type properties, and the outer face of the layer has no recesses; provide a male embossing tool (5, 5) with an outer face with at least one protuberance corresponding to at least one desired embossing relief that is to be formed on the sheet element (60) after embossing; and cooperation of the male embossing tool (5, 5) with the female embossing tool (6) such that the outer layer (44) of the female embossing tool (6) undergoes a plastic deformation which creates at least one recess (42, 42) of a shape complementary to the protuberance(s) (41, 41) of the male embossing tool (5, 5).

The embossing-laminating device includes load bearing structure with at least two side members, a first path, for a first ply of web material, and a second path for a second ply of web material. Along the first path, a first pressure roller and a first interchangeable embossing roller are arranged, which define therebetween a first embossing nip for the first ply of web material. Along the second path a second pressure roller and a second interchangeable embossing roller are arranged, which define a second embossing nip for the second ply of web material. The embossing-laminating device also includes a magazine including a plurality of seats for a plurality of interchangeable embossing rollers, as well as at least a first manipulator for replacing embossing rollers.
