METHOD AND DEVICE FOR HEATING AN EMBOSSING ROLLER IN AN EMBOSSING-LAMINATING DEVICE

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. Pour c...

Summary: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. Pour chauffer efficacement un rouleau de gaufrage pour le gaufrage d'un matériau de bande de cellulose, un dispositif d'induction électromagnétique (19,20) est employé de manière à induire un courant de Foucault de manière préalable sur la surface externe du rouleau de gaufrage (4, 5). Les courants de Foucault sont conçus de manière à chauffer de manière appropriée la surface extérieure du rouleau de gaufrage.
