Felt Rollers
Non-Marking Support for High Surface Finish Aluminum Profiles
CALM felt rollers provide smooth, stable profile support throughout the aluminum extrusion process, helping reduce scratches, pressure marks, and surface contamination while improving conveying reliability.
Why Surface Contact Matters
Throughout the extrusion process, aluminum profiles remain in continuous contact with conveying rollers. If the roller surface is uneven, worn, or contaminated, even slight contact can affect the final surface finish.
CALM felt rollers provide a smooth contact surface that helps protect aluminum profiles while ensuring stable conveying across different production stages.
Why Choose CALM Felt Rollers?
Smooth Surface Contact
Provides uniform support to help reduce scratches, pressure marks, and friction during conveying.
No Fiber Shedding
Minimizes fiber contamination to help maintain clean aluminum surfaces.
Resin-Hardened Construction
Improves rigidity and dimensional stability for longer service life under continuous operation.
Custom Manufacturing
Available in multiple materials, diameters, and lengths to match different extrusion lines.
Built for High Surface Finish Aluminum Profiles
Surface quality becomes increasingly important for aluminum profiles with decorative or functional finishes. CALM felt rollers are specially designed for applications where even minor surface defects are unacceptable.
