Faster speed changes
Low rotating mass reduces the required acceleration torque. This can support faster starts and stops in the process.
Application & Value
CFRP Machine Roller
Guide continuous webs with low inertia and high dimensional stability.
Challenge
Paper, film and nonwoven webs need to move uniformly through production equipment. Rollers must respond to speed changes while limiting deflection under load. High inertia and deformation can affect web tension and process consistency.
Solution approach
A CFRP roller body can combine high bending stiffness with low rotating mass. This supports acceleration and deceleration and can help maintain consistent web handling. The surface, bearings and journal connections must suit the web material and operating loads.
The benefits
More consistent product quality
Low deflection supports consistent contact with the web. This can reduce wrinkling and associated scrap.
Wider working widths
High specific stiffness can enable longer rollers, creating scope for wider webs while limiting deflection.
What could this mean for your product?
In rotating components, mass also affects the dynamic behaviour of the overall process. Lightweight construction can therefore contribute to process quality when stiffness, surface and bearings are considered together. This relationship also applies to other rapidly moving machine components.
