Endless Felt Belts
Non-Marking Conveyor Solutions for Aluminum Extrusion
CALM endless felt belts provide smooth, non-marking profile conveying throughout the aluminum extrusion process. Manufactured without seams, they help reduce scratches, improve surface finish, and deliver reliable performance across different temperature zones.
Why Choose CALM Endless Felt Belts?
Designed for smooth, non-marking conveying, CALM endless felt belts help protect aluminum profiles while delivering stable performance and long service life.

Non-Marking Conveying
The endless construction eliminates stitched joints that may create uneven contact, helping protect aluminum profiles from scratches and conveying marks.

Reliable High-Temperature Performance
Different felt materials are available for ultra-high, high, medium, and low-temperature conveying applications.

Excellent Wear Resistance
Premium fibers provide long service life and reliable performance under continuous operation.

Stable Conveyor Performance
Accurate dimensions and consistent construction help maintain stable conveying and reduce production interruptions.

Low Fiber Shedding
Engineered to minimize fiber contamination and help maintain clean profile surfaces.

Custom Manufacturing
Available in customized widths, lengths, thicknesses, and materials for different extrusion lines.
Why Endless Construction Matters
A smooth belt creates a smoother profile.
CALM endless felt belts are manufactured without joints, helping reduce conveying marks, improve surface protection, and deliver more stable performance throughout the extrusion process.
