Electrode slitting machine – Automatic roll-to-roll slitter-rewinder for battery electrodes

Calemard designs and manufactures high-precision automatic slitter-rewinders dedicated to battery electrode converting, from laboratory R&D and pilot lines to high-volume Gigafactory production.

Engineered for lithium-ion battery manufacturing, these machines ensure accurate slitting, stable web tension and consistent rewinding quality when processing:

• Anode materials
• Cathode materials
• Primed coated copper foils
• Primed coated aluminum foils

Designed to meet the demanding requirements of battery cell production, Calemard electrode slitting machines help manufacturers achieve precise slit widths, excellent edge quality, reduced material waste and reliable production performance.

The range includes scalable solutions adapted to every stage of industrial development, from research and process validation to continuous large-scale manufacturing.
