The embossing device includesa first path for a first ply of web material; along the first path, a first embossing roller provided with embossing protrusions; a first heating device associated with the first embossing roller to heat the surface of the first embossing roller; at least a first functional roller adapted to perform an action on a ply of web material. The first functional roller is provided with a rotation arrangement, adapted to keep the first functional roller in rotation during a temporary stoppage of the embossing device, with the first functional roller spaced from the first embossing roller and with the first ply of web material stationary in the first path.

An embossing device and a method for embossing, employing an electromagnetic induction device such as to induce an eddy current prevalently on the outer surface of an embossing roller. The eddy currents are such as to prevalently heat the outer surface of the embossing roller.
