Abstract: An embossing device and a method for embossing, employing an electromagnetic induction device (19, 20) such as to induce an eddy current prevalently on the outer surface of an embossing roller (4, 5). The eddy currents are such as to prevalently heat the outer surface of the embossing roller.

Abstract: The mechanical ply-bonding member (7) for a mechanical ply-bonding unit (1) has a side surface with a plurality of protuberances (21) spaced by cavities (23), provided for example through engraving. The cavities are at least partially filled with a yielding material (25). The mechanical ply-bonding unit comprises a mechanical ply-bonding member (7) and an anvil member, for instance an anvil roller (9).

Abstract: For bonding together two or more plies of cellulose fibers, the plies are fed to a lamination nip between a ply-bonding rotating element and an anvil element. The ply-bonding rotating element has rollers with a cylindrical surface provided with small protuberances co-acting with larger protuberances provided on a cylindrical surface of the anvil rotating element. The plies are bonded, if necessary with the aid of a functional fluid, not containing adhesive, due to the effect of the pressure between the protuberances.

Abstract: The unwinder comprises an unwinding station (15), in which to arrange a reel to be unwound. In the unwinding station there is arranged a series of guide rollers (31, 33, 35), defining a feed path of the web material (N0, N1). There are also provided: a cutting member (37) adapted to cut a web material (N0) coming from an exhausted reel (B0); and splicing members (37, N0) to splice a trailing edge (LC) of a first web material (N0) coming from an exhausted reel (B0) to a leading edge (LT) of a second web material (N1) coming from a new reel (B1); A pick-up device (41) is configured to pick up the leading edge (LT) of the second web material (N1) from a temporary retaining element (9), carried by a transfer unit (6) to transfer reels (B0, B1) to the unwinding station (15).
