As a professional sidewall conveyor belt manufacturer, QBF Rubber knows that in steep angle or vertical conveying applications, once the sidewall detaches, the cleat tears, or the base belt breaks, the result is not just a replacement shutdown — it is a complete production line interruption.
For overseas customers, choosing a sidewall conveyor belt supplier is not about selecting the “unit price”, but about selecting the predictability of long-term operating costs.
QBF Rubber’s answer is: building a closed-loop quality control system from raw material formulation to on-site operation.
1. Raw Material Control – 100% Incoming Inspection
Rubber, fabric, and steel cord — every batch is inspected before production, covering tensile strength, abrasion, aging, and adhesion strength. Materials are aligned with European standards. The more challenging your application, the more obvious the advantage of QBF Rubber’s customized compounds.
2. Process Control – Fully In-House Production
QBF Rubber is one of the few sidewall conveyor belt manufacturers that achieves fully in-house production from mixing, base belt, sidewall, cleat to vulcanization. During production, full in-process inspection is implemented: dimensional check, tensile strength, adhesion, hardness, and elongation at break.
Every process is controlled. Non-conforming semi-finished products do not move to the next stage.
3. Final Inspection – Belt-by-Belt Check
Once a belt is produced, each belt goes through dimensional re-check and visual appearance inspection, with optional performance re-testing. Only products that pass all final inspections enter the packaging stage.
4. Packaging Inspection
Cleanliness check, packaging method confirmation, marking verification, and protection measures — ensuring that QBF Rubber sidewall conveyor belts arrive at the customer’s site in perfect condition.
5. Full Traceability
Every QBF Rubber sidewall conveyor belt has its own “ID card”. Customers can trace back via batch number to the raw material source, production line, vulcanization date, and all inspection data.
6. Operational Support
Pre-delivery: assist with selection calculation, splicing solutions, and installation guidance.
During operation: support remote failure analysis or on-site engineer dispatch.
Long-term: provide periodic wear assessment and preventive maintenance recommendations.
QBF Rubber sidewall conveyor belt quality control = incoming inspection + process control + belt-by-belt final inspection + packaging check + full traceability + operational support

As part of QBF rubber’s commitment to full lifecycle service for sidewall conveyor belts, the company recently organized a specialized hands-on training session on ST3150 B1500 steel cord sidewall conveyor belt jointing technology at its manufacturing base. The training was conducted using actual products from a Japanese power plant project, focusing on the critical jointing techniques under the “rope-free zone” design.
The training was led by a senior after-sales technical manager with over 10 years of field installation and jointing experience. The curriculum covered the complete jointing process for ST3150-grade sidewall belts, including steel cord preparation, stepped overlap layering, and vulcanization process control. Training samples were taken from the same production batch as the Japanese power plant order, strictly adhering to Japanese acceptance standards, ensuring every technical detail meets international client expectations.
Joint quality is decisive for conveyor belt service life and operational safety. For sidewall belts, jointing involves not only high tensile strength but also sidewall sealing and operational stability—making the process considerably more complex than standard conveyor belt jointing. The hands-on session emphasized “rope-free zone” operating procedures, achieving joint strength above 85% of the original belt while effectively preventing stress concentration and material leakage risks.
QBF rubber’s after-sales service team has years of expertise in conveyor belt installation and jointing, with particular strength in large-lift-height, large-specification sidewall belts, as well as confined-space and challenging site conditions. Our technical core comprises professionals with over a decade of field experience, proficient in developing customized jointing solutions and troubleshooting across diverse operating environments. QBF rubber has established a rapid-response service network covering key industrial regions globally, implementing standardized quality management from site survey and solution design through to construction and final acceptance, ensuring every service delivery is precise and efficient.

The biggest weakness of traditional sidewall belts? The splice. Splices are not only the weakest point in terms of strength, but also lead to joint shock, material leakage, jamming, and shorter service life.
Today, we are sharing with you the QBF Truly Endless Belting Production Line – a dedicated production line that solves splice problems at the source.
Core Equipment
Single-Strip Winding Machine
This machine spirally winds a continuous fabric strip around the mold, ensuring a truly endless belt with no splice, eliminating tension loss caused by joints.
Integrated Vulcanization Press
The base belt and sidewall are vulcanized together in one step, eliminating the risk of delamination that comes with post-production bonding.
Custom Molds
Using European standard molds for sidewall production to achieve optimal material discharge efficiency and lower running resistance.
Production Specifications
Length:2-30m
Thickness:≥8mm
Belt width: ≤1500 mm(customizable)
Sidewall height: Customizable

Quality Assurance: Every endless belt on the production line undergoes strict testing for thickness uniformity and tension distribution, ensuring compliance with ISO and long-term European operating standards.
Key Advantages – Why “No Splice” Matters
No weak point – Zero strength loss at the splice. Every inch is as strong as the next.
No joint shock – Smooth operation keeps belt scales and weigh feeders accurate.
No leakage – One-piece molded structure (no post-bonded parts) prevents fine materials from escaping through gaps.
Longer life – Even stress distribution reduces fatigue cracking.
Field data: 30%-50% longer life than spliced belts
Conclusion
The QBF Truly Endless Belting Production Line replaces the traditional “cut and splice” method with a truly seamless winding and vulcanization process, delivering a conveyor belt that is stronger, more durable, and runs more accurately.
If you are struggling with frequent belt breaks at the splice, or if your weighing system suffers from low accuracy due to joint harmonics, it is time to switch to the truly endless belting standard.
