JIAKE Delivers High-Speed Two-Rib Cold-Rolled Rebar Machine with Servo Flying Shear to Tunisia
Growing Industrial Rebar & Mesh Processing Demand in Tunisia
The construction and building materials sectors in North Africa, particularly in Tunisia, are experiencing steady modernization. Across cities like Tunis, Sfax, and Sousse, local concrete component plants, steel rebar distributors, and wire mesh manufacturers require consistent supplies of high-strength two-rib cold-rolled ribbed steel bars (2-rib deformation steel). These ribbed bars significantly improve concrete bonding strength and yield strength compared to plain smooth round wire.
A leading steel processing supplier in Tunisia sought to expand their product catalog by manufacturing and selling high-quality cut-to-length 3-rib/2-rib rebar bars locally. To supply construction rebar processors and mesh production facilities across Tunisia efficiently, the client required a dedicated production line capable of continuous cold-rib rolling, high-speed straightening, and non-stop shearing into precise 3-meter to 6-meter bar lengths.
To meet the client’s strict requirements for production speed, length precision, and rib profile clarity, JIAKE Machinery custom-engineered an industrial-grade solution: the JIAKE High-Speed Two-Rib Cold-Rolled Rebar Processing Machine featuring an advanced Servo Flying Shear System.
Technical Solution: JIAKE Two-Rib Rebar Line with Servo Flying Shear
Standard stop-and-cut shearing systems create bottlenecking during high-speed cold rolling. To achieve maximum throughput, JIAKE engineers integrated a synchronous servo motor-driven flying shear mechanism that tracks the moving ribbed bar and cuts it instantly without interrupting the upstream rolling process.
| Machine Component | Tunisian Client Requirement | JIAKE Customized Engineering Solution |
|---|---|---|
| Rib Deformation Process | High-clarity 2-rib cold-rolled profile for local rebar & mesh factories | Heavy-duty cold-rolling reduction cassette with carbide crescent rollers for sharp 2-rib geometry. |
| Straightening Unit | High-flatness straight bars without surface scratches or twisting | Multi-roll alloy straightening wheels with individual pressure adjustment. |
| Cutting Mechanism | High-speed non-stop cutting into 3m – 6m fixed lengths | Servo Flying Shear System: Dynamic tracking rotary shear with Panasonic/Siemens servo control. |
| Cut Length Precision | Strict tolerance within ±2mm for local commercial sale | High-resolution encoder feedback integrated with PLC touch screen interface. |
| Raw Material & Target Product | Low-Carbon Steel Wire Rod Coils | Finished Output: 3m – 6m 2-rib ribbed rebar bars bundled for direct distribution. |
Key Engineering Features of JIAKE Two-Rib Rebar Processing Machine
1. Heavy-Duty Cold-Rolling Cassette for Sharp 2-Rib Profiles
The raw wire rod is drawn through JIAKE’s specialized 2-rib cold-rolling cassette. Utilizing tungsten carbide rollers, the machine cold-works the steel surface under heavy pressure, forming sharp, uniform two-rib crescents. This strain-hardening process dramatically increases the tensile and yield strength of the steel bar, exceeding international standards for reinforcing steel.
2. High-Precision Servo Flying Shear System (Non-Stop 3-6m Cutting)
The standout innovation in this Tunisian line is the servo flying shear unit. As the 2-rib bar exits the straightening rolls at high linear speeds, a high-resolution optical encoder measures the precise length. The servo motor accelerates the cutting carriage to match the exact speed of the moving bar, executes a clean hydraulic or mechanical shear, and returns to the home position instantly. This enables continuous production of 3m, 4m, 5m, or 6m rebar bars with millimeter-level accuracy and zero line stoppage.
3. Automatic Stacking & Bundling Table
Once sheared, the 3-6m ribbed bars fall onto a pneumatic automatic discharge rack. The system neatly collects and aligns the bars into bundles, making them immediately ready for strapping, crane lifting, and commercial dispatch to local Tunisian mesh manufacturers and construction sites.

Commissioning Results & Market Impact in Tunisia
JIAKE engineers conducted complete on-site installation support and operational calibration at the client’s facility in Tunisia. During production trials, the line operated smoothly at full linear speed, delivering perfectly straightened 2-rib rebar bars sheared accurately to 3m and 6m lengths.
With this new JIAKE equipment, the Tunisian supplier successfully launched their local commercial rebar line, supplying premium 2-rib bars to nearby rebar processing shops and welded wire mesh factories at highly competitive prices.
“The JIAKE two-rib rebar machine exceeded our expectations. The servo flying shear system allows us to run non-stop without interrupting the rolling process, producing perfectly cut 3m and 6m bars. Our local customers in Tunisia are extremely satisfied with the rib quality and straightness of the bars. JIAKE is a trusted partner for steel processing machinery.”
