Web-optimized roller profiles
Separator films are among the most sensitive functional layers in lithium-ion battery manufacturing. Their task: to electrically separate the anode and cathode while allowing ions to pass through. With increasing demands on energy density and miniaturization, these films are becoming thinner and thinner – in some cases less than 10 µm – and at the same time wider. Even the smallest deviations in web tension or local stress peaks can lead to cracks, web fluctuations, or rejects.To meet these specific requirements, INOMETA develops web tension-optimized roller profiles that are specifically tailored for use in separator film production. The focus is on mechanical properties and functional surface technologies that enable gentle material handling with maximum web stability – even at high cycle rates and with the most sensitive substrates.

These design measures help to optimally support the tear resistance of ultra-thin separator films, compensate for tolerances in web travel, and expand the process windows for modern production facilities.
To meet the special requirements of ultra-thin separator films, INOMETA develops web tension-optimized roller profiles that are specifically designed for mechanical precision and process-stable web guidance. The focus is on design, material behavior, and surface functionality – tailored to the sensitive structure of separators with a thickness of < 10 µm.In addition, the rollers are specifically designed to ensure that even the slightest web tension can be reliably achieved. Thanks to reduced inertia, minimized starting torque, and very low breakaway torques, they enable highly sensitive, controlled web guidance – even with extremely thin and sensitive separator films.
Design features & innovations:
In addition to these design advantages, INOMETA offers a comprehensive range of rolls for web tension-related applications in battery and film processing – from calendering to winding lines:
• Heating rollers INOheat® with precise temperature control• Sensor rollers and INOlogic® for intelligent web tension control• Roller solutions for drying, coating, and laminating• Smart rollers with integrated data acquisition• Modular roller systems for retrofitting or plant conversion
WinCore® aluminium winding cores are used as supplementary system components. They are low-abrasion, manufactured with high precision and specially developed for the tension-stable winding and unwinding of sensitive substrates such as separator films – optionally with RFID technology, winding support or cut-resistant surface.The result is an optimally coordinated overall system consisting of roller and sleeve, which combines mechanical precision, digital integration, and high process reliability for processing ultra-thin separator films.
The development of train-optimized roller profiles for ultra-thin separator films is a testament to INOMETA’s comprehensive expertise in battery and film manufacturing. Beyond this specific application, INOMETA offers an integrated portfolio of solutions that combines mechanical precision, innovative surfaces, and digital intelligence. From roll and winding technologies to PROTEK® roller coatings and digital solutions, INOMETA supports its customers in maximizing efficiency, quality, and process reliability along the entire production chain.
