Calendering Apparatus for the Production of an Electrode

A calendering apparatus is provided for the mechanical compacting of an electrode, in particular of a flat form. The calendering apparatus includes a compacting device and a guide roller. The guide roller is configured to feed the electrode to the compacting device during the operation of the calendering apparatus. The guide roller has first regions and second regions in certain parts of its rolling surface, and the first and second regions have different thermal conductivities.
