Features
🟠 Smooth & Uniform Surface
The felt belt features a smooth, dense, and uniform surface without significant unevenness or loose fibers. This helps minimize friction and surface marks, providing gentle protection for aluminum profiles during conveying.
🟠 Endless & Seamless Construction
Calm conveyor felt belts are manufactured with an endless, seamless construction, eliminating joints and stitched connections that can become weak points. This helps improve durability, running stability, and service life.
🟠 High Structural Strength
Each heat-resistant felt belt undergoes multiple needle-punching processes under controlled tension. The dense fiber structure provides excellent dimensional stability and helps prevent loosening, delamination, and peeling during continuous operation.
🟠 Resin Treatment
Full-resin or semi-resin treatment is available to improve wear resistance and extend belt service life. It can also reduce the adhesion of aluminum chips, dust, and other contaminants to the felt surface.
🟠 Lightweight & Easy to Handle
Despite its high strength and heat resistance, the felt belt is lightweight and easy to handle. This makes installation, removal, storage, and replacement more convenient during routine maintenance.
🟠 Sound & Shock Absorption
Industrial felt naturally provides sound and vibration absorption, helping reduce operating noise and mechanical vibration. This contributes to a quieter and more comfortable working environment.
🟠 Stable Continuous Running
Calm endless felt belts feature low elongation of less than 1%, helping maintain stable dimensions during continuous operation. They can withstand frequent rotation with minimal deformation or deviation, supporting reliable and efficient production.
How Industrial Felt Belt is Made
Calm endless felt belts are manufactured through a controlled carding, needle-punching, forming, joining, cutting, and inspection process. The exact process and material structure are adjusted according to the required temperature resistance, belt size, and application.
1. Fiber Preparation
Selected industrial fibers such as PBO, Kevlar, Nomex, or Polyester are opened and carded to separate and align the fibers while removing impurities and short fibers.
2. Needle Punching
The prepared fibers are formed into felt layers through repeated needle punching. The needles mechanically interlock the fibers, creating a dense, strong, and uniform felt structure.
3. Belt Forming
The felt layers are formed to the required thickness and dimensions. Controlled tension and forming processes help achieve consistent density and dimensional stability throughout the belt.
4. Endless Belt Processing
The felt is processed into an endless, seamless belt according to the required belt size. This construction eliminates conventional joints and helps provide smooth and stable continuous running.
5. Resin Treatment
When required, semi-resin or full-resin treatment can be applied to improve wear resistance, durability, and resistance to aluminum contamination.
6. Cutting & Finishing
The finished felt belt is precisely cut and processed according to the customer's specifications. The edges and surface are carefully checked to ensure a clean and consistent finish.
7. Final Inspection
Before shipment, each belt undergoes quality inspection for dimensions, thickness, surface condition, structure, and overall workmanship to ensure it meets the required specifications.
