Deflection and guide rollers in battery manufacturing

Deflection and guide rollers for precise web guidance in battery production

In battery and battery foil production, deflection and guide rollers form the backbone of a stable process chain. Their task is to guide sensitive substrates through complex plant layouts with geometric precision and low tension. As predominantly passive components, they have a significant influence on running behavior and web stability – especially with the very low web tensions required in battery production.
INOMETA develops guide rollers made of aluminum, CFRP, and GRP that are specifically tailored to the chemical, thermal, and mechanical requirements of electrode and separator foil production. Through a combination of lightweight construction, precision bearings, and functional surfaces, we ensure that the material properties remain unchanged throughout the entire value chain.

Geometric stability from substrate production to coating

Even during the processing of metallic carrier films, the quality of the web guidance determines the efficiency of subsequent steps. Our guide rollers enable precise changes in direction without additional mechanical stress on the material.

• Minimal starting torques: Thanks to the use of lightweight materials and specialized bearing concepts, the rollers start up reliably even with the slightest web tension. This prevents slippage and scratches on sensitive surfaces.
• Focus on precision: High concentricity and minimal bearing tolerances limit positional deviations and stabilize the web path even at high process speeds.

Thermal dimensional stability and dynamics in electrode manufacturing

In electrode manufacturing – especially during the coating and drying processes – rollers are exposed to extreme conditions. This is where CFRP guide rollers fully demonstrate their technological advantages:

• Thermal stability: Unlike metal rollers, CFRP exhibits excellent thermal dimensional stability. Even in drying sections with high temperatures, the rollers do not warp, ensuring that the web guidance remains precise.
• Low inertia: CFRP lightweight constructions minimize the moment of inertia. The result is low-vibration running behavior and an immediate response to speed changes, which reduces the reject rate when starting up the systems.
• Climatic resistance: For vacuum drying or humid environments, we offer specialized designs that are corrosion-resistant and low-maintenance.

Process reliability in cell production and finalization

From stacking and contacting to cell finalization (forming, aging), smooth web guidance is essential for automated high-speed processes. Deflection and guide rollers from INOMETA act as passive stabilizing elements here.
Their high rigidity and defined surface geometry ensure precise positioning of the materials in the automatic assembly machines. Thanks to their durable construction made of aluminium or composite materials, they increase plant availability and reduce unplanned downtime in 24/7 production.

Process reliability and plant availability in cell finalization

Smooth and consistent web guidance remains a key factor in cell finalization as well—for example, in pretreatment, forming, degassing, aging, and end-of-line testing. Deflection and guide rollers support trouble-free material flow and create stable conditions for testing and quality assurance processes.
The durable and low-maintenance design of the deflection and guide rollers made of aluminium, CFRP, or GRP helps to avoid unplanned downtime and ensure high plant availability. Different bearing and design variants enable precise integration into existing plant layouts and support process-reliable design even in late stages of production.

Systemic integration into the overall INOMETA concept

Deflection and guide rollers are not an isolated product, but part of a holistically designed roller solution. They complement active components such as drive and tension rolls as well as sensory measuring rollers to form a perfectly coordinated system.
This interaction results in process-specific overall concepts in which web guidance, surface functionality (e.g., PROTEK^® coatings), and mechanical design are precisely tailored to the respective battery technology.
