Calender Transport Roller and Calendering Device for the Production of Electrodes for a Battery Cell

Abstract

A calender transport roller for a calendering device for production of electrodes for a battery cell, where an electrode strip is conveyable by the calender transport roller to or from a pair of calendering rolls and where the electrode strip has a flat conductor strip and a coating which is applied in portions at least on a side that faces the calender transport roller. The calender transport roller includes a contact region on a shell surface of the calender transport roller where the contact region is contactable with the electrode strip, an adjusting portion in the contact region, and a widening device where a diameter of the transport roller in the adjusting portion is changeable by the widening device such that a height difference between a coated portion of the electrode strip and an adjoining uncoated portion of the electrode strip is compensated.
