Product Overview
Our specialized handling belts are engineered for the rigorous demands of automated sorting centers, banking machines, and high-speed mailrooms. Whether transporting thin airmail envelopes, thick corrugated cardboard, or crisp banknotes, these belts provide the constant coefficient of friction and dimensional stability required for jam-free operation.
Utilizing advanced rubber compounds (such as NBR or Natural Rubber) and non-marking synthetic covers, our belts ensure every document reaches its destination in pristine condition.

Key Technical Features
- Superior Grip & Traction: High-friction covers (available in various Shore A hardnesses) ensure instant “grab” and precise release of paper and cardboard, even at speeds exceeding 10m/s.
- Anti-Static Properties (ESD Safe): Integrated conductive layers dissipate static electricity buildup caused by paper friction. This prevents document sticking, electronic interference, and potential fire hazards in high-volume sorters.
- Non-Marking Surfaces: Specially formulated compounds ensure that no carbon residue, rubber dust, or color transfer occurs on sensitive white envelopes, legal documents, or currency.
- Constant Friction Coefficient: The surface maintains its “tackiness” over millions of cycles, resisting the “glazing” effect common in lower-quality belts.
- Flexible & Durable Core: Reinforced with high-modulus polyester or aramid cords for low-stretch performance and high flexibility around small-diameter pulleys.
Sector-Specific Applications
1. Postal & Mail Sorting
- Letter Sorters: Feeder belts, diverter belts, and stacker belts for high-speed letter processing.
- Parcel Handling: Heavy-duty top-cover belts for transporting and gapping corrugated cardboard boxes.
2. Banking & Financial Services
- ATM & Currency Counters: Ultra-precise feeder belts for banknote validation and dispensing.
- Check Processing: High-friction transport belts for rapid scanning and MICR reading.
3. Print & Finish
- Folder Gluers: Feed belts for cardboard box folding and gluing lines.
- Inserting Systems: Collating and inserting belts for high-volume direct mail.
