Device for heating an embossing roller in an embossing-laminating device

An embossing device comprising:

• a first path, for a first ply of web material;
• along the first path, a first pressure roller, coacting with a first embossing roller, the first embossing roller and the first pressure roller defining a first embossing nip for the first ply of web material, the first embossing roller comprising embossing protrusions;
• at least a first electromagnetic induction device externally associated with said first embossing roller to heat a surface of said first embossing roller;
• wherein said first electromagnetic induction device is connected to a first generator device to supply said first electromagnetic induction device with electromagnetic induction currents adapted to generate an electromagnetic flux directed toward said first embossing roller and wherein an operating frequency of said electromagnetic induction currents is such as to generate eddy currents on said first embossing roller such as to substantially follow a profile of an outer surface of said first embossing roller;
• machine-stopping means configured to move said pressure roller away from said embossing roller, simultaneously maintaining the embossing roller rotating at a speed such that the ply of web material can be made to rub on the outer surface of the embossing roller without breaking.
