Sensor rollers for electrode coating in battery manufacturing
The coating of electrode foils in lithium-ion battery production requires maximum process stability and precisely controlled web tension – especially for thin aluminium or copper substrates coated with highly filled slurries. Even slight deviations in web tension can lead to drying defects, stress cracks, delamination, or uneven coating application. For continuous monitoring and control of web forces, INOMETA offers precise sensor rolls with integrated web tension measurement – developed for use under real production conditions in high-speed lines.

INOMETA’s sensor rolls are mechanically high-precision engineered roller bodies with integrated force transducers in their bearing journals – designed for applications with sensitive substrates such as coated electrode foils. Depending on process requirements, aluminium, stainless steel, or CFRP rollers are used, which are optimized for minimal sag and maximum rigidity. The measurement is carried out directly on the bearing axis via high-resolution radial force sensors – low-interference, overload-protected, and fully integrable into closed-loop control circuits. Thanks to the precise tension control, homogeneous wet film thicknesses, stable layer transitions, and deformation-free transport can be ensured, even at high web speeds.
The sensor rollers (e.g., SWA series or CLS cantilever design) are individually adapted to the application – from slurry coating to the drying zone. The following is an overview of the most important technical features:

Depending on the plant layout and material flow, various sensor types are available – including classic SWA sensor rollers, space-saving CLS/CSW cantilever variants, and RMA and WTS web tension sensors, which can be integrated directly into existing systems without mechanical modifications.This variety enables seamless integration into continuous coating or calendering lines – both in horizontal and vertical installation positions. Precise tension control can be achieved even with small wrap angles or a minimum number of rollers.
INOMETA sensor rollers enable continuous web tension control in all critical process stages of electrode coating.
Typical areas of application:
The sensor rolls can also be integrated into existing systems – ideal for retrofitting coating lines with increased precision requirements.
