In the fast-evolving wire and cable industry, efficient bunching of fine multi-strand conductors is essential for producing high-quality electronic wires, automotive harnesses, and specialty cables. The RLB Double Twist Bunching Machine (models 315E to 1250) delivers industry-leading performance, combining high rotational speeds, precise lay control, and full automation to meet the demands of modern high-volume production.
Designed for stranding multi-stranded copper wires, tinned wires, enameled wires, and copper-clad aluminum wires, this double-twist buncher achieves exceptional productivity while maintaining uniform lay length, stable tension, and superior surface quality.
Equipment Description
Full-automatic dual-twisting stranding machine adopts PLC + HMI system control. Operators can easily preset lay pitch, lay direction, and take-up tension through the intuitive touch-screen interface. The operation is simple, stable, and highly efficient.
The machine delivers up to twice the output of single-twist systems while maintaining superior conductor integrity and electrical performance.
Kısa Teknolojik Süreç
Pay-off → Double-Twist Bunching Head → Constant Tension Control → Precision Lay Pitch → Automatic Take-up Incoming single wires from pay-off racks (in-line or multi-head) → High-speed double-twist bunching head (100% back-twist) → Advanced tension control system → PLC-controlled lay pitch and direction → Finished compact, bright, high-quality multi-strand bunched conductor wound onto take-up bobbins.
The double-twist mechanism provides two twists per rotation, doubling output compared to single-twist systems while maintaining superior conductor integrity and electrical performance.

Core Technical Advantages & Operational Benefits
- Full-Automatic Dual-Twisting Technology: Delivers up to twice the productivity of single-twist systems with consistent lay length and excellent flexibility.
- PLC + HMI Intelligent Control: Simple touchscreen interface for preset lay pitch, lay direction, and take-up tension — real-time monitoring and easy operation.
- Constant Tension Control: Ensures stability from full to empty bobbin, minimizing wire breakage and defects.
- Geniş Uygulama Alanı: Handles ultra-fine wires (Φ0.04 mm) up to larger conductors (Φ3.2 mm) across eight models.
- Flexible Pay-off Configurations: Supports both in-line pay-off racks and double-bobbin multi-head pay-off racks for seamless integration into existing lines.
- Robust & Low-Maintenance Design: Carbon-fiber composite options (select models) and closed safety enclosure with noise isolation improve operator comfort and machine longevity.
These features result in bright, compact, high-quality bunched conductors ready for downstream extrusion, laying-up, or final cable assembly.
