Reliable Tubular Stranding And Closing Machines For Steel Strands And Ropes, Balancing Quality And Productivity

Tubular stranding machines general information
This type of machine is called “tubular stranding” because of the geometric shape of the main torsion block, its another name is “tubular type stranding machine”. It’s a tubular or cylindrical type strander. Among the people and among manufacturers it’s called as a tubular -type stranding.

Tubular stranding machines are designed for stranding steel, copper or aluminum uninsulated cores, as well as for booking cable and twisting of steel cables. The standard of the twisted core design: 1+6 / 1+12 / 1+18. The advantage of the machine is high operating speeds, which has a positive effect on the line speed and total production capacity of the line.

The main torsion block of the machine is a cast or assembled cylindrical cigar–shaped (cylindrical) type rotor - "cigar", that containing consoles with installed pay-off coils that have wire workpiece. The coil with a central core is installed in front of the rotor along the axis of the line in the separate cantilever-type pay-off machine. Workpieces, including the central one, pass through dies of the torsion block and, after passing the full length of the torsion unit, link up in the distribution outlet at the output. The tension control of the workpieces is carried out by using hysteresis brake couplings in semi-automatic mode or band mechanical brakes (optional). The rotating rotor rotates at the support points of large bearings. Each bearing is equipped with an oil circulation system to provide lubrication and cooling.

The stranding of workpieces is happening in the master tool - die, that installed right after the snake element along the line axis. The tightening is carried out by a wheeled type haul-off unit. The pay-off procedure of twisted cores onto the coil is carried out by a column-type or portal-type pay-off machine. The meterage calculated is carried out by the meterage counter, that installed in front of the haul-off unit. The torsion unit, the haul-off unit and the pay-off machine are driven by independent separate motors, which synchronized with each other and with the control cabinet. There are alternative transmission systems with a common motor and transmission shafts. The monitoring and control system is implemented through the PLC controller and the touch panel.

​Reliable Tubular Stranding And Closing Machines for Steel Strands and Ropes: Balancing Quality and Productivity​
In industries where strength, durability, and precision matter—such as construction, mining, maritime, and heavy lifting—the quality of ​steel strands and ropes​ directly impacts safety and performance. At the core of premium steel strand and rope production are ​tubular stranding and closing machines,which determine the consistency, tightness, and overall integrity of the final product. Beyde, a trusted name in advanced wire and cable machinery, delivers ​highly reliable tubular stranding and closing solutions​ that perfectly balance ​production efficiency​ with ​uncompromising quality.

Why Tubular Stranding and Closing Machines Matter?
​Tubular stranding machines​ are engineered to twist multiple wires or strands into a precise, concentric formation within a rotating tube. This process is essential for creating ​compact, high-tensile steel strands​ that serve as the foundation for ropes used in demanding environments. Following stranding, the ​closing machine​ (also known as a forming or closing die machine) compresses and shapes the stranded bundle to form a firm, durable rope structure with enhanced load-bearing capacity and resistance to deformation.
Whether you're producing ​galvanized steel strands, stainless steel ropes, pre-stressed concrete strands, or mining ropes, the performance of these machines directly affects:

​Tensile strength & load capacity​
​Resistance to fatigue & corrosion​
​Strand uniformity & surface finish​
​Production speed & operational reliability​

Beyde’s Tubular Stranding and Closing Machine Advantages
At Beyde, we’ve designed our ​tubular stranding and closing lines​ to meet the exacting standards of modern steel strand and rope manufacturers. Here’s what makes our machines stand out:
1. ​High-Precision Stranding for Consistent Performance​
Our tubular stranding machines feature:

​Servo-driven or planetary drive systems​ for accurate, repeatable twisting with adjustable lay lengths (typically 100–10,000 mm, customizable).
​Multi-layer stranding capability​ (up to 19, 37, or even 61 wires/strands), ideal for complex rope structures.
​Tension control systems​ that maintain uniform wire tension during stranding, minimizing breakage and ensuring strand uniformity.
​Large-capacity stranding cages​ (up to φ800–1200mm) to support high-volume production of thick or multi-strand cables.
2. ​Advanced Closing Technology for Superior Rope Integrity​
The closing (or forming) stage is where stranded units are compressed into a dense, solid rope. Beyde’s closing machines offer:

​Hydraulic or mechanical closing dies​ with precise temperature and pressure controls (for thermally assisted closing if needed).
​Adjustable closing molds​ to accommodate different strand diameters and rope configurations.
​Real-time monitoring systems​ to ensure consistent closing pressure, reducing defects like loose cores or uneven surfaces.
​Integrated cooling or lubrication options​ to enhance die life and surface finish.
3. ​Robust Construction & Easy Maintenance​
Built with ​high-grade alloy steel frames, hardened gears, and sealed bearings, our machines withstand continuous, high-load operation. Key features include:

​Modular design​ for quick part replacement and easy upgrades.
​Low-vibration operation​ to extend component lifespan.
​User-friendly control panels​ (PLC + HMI interfaces) for intuitive operation, parameter setting, and troubleshooting.
​Minimal downtime​ with tool-free die change systems and automated lubrication.
4. ​Customizable & Scalable Solutions​
We understand that every manufacturer has unique requirements. That’s why Beyde offers:

​Tailored machine configurations​ based on strand type (e.g., 7-wire, 19-wire, compacted strands), rope diameter, and production speed.
​Options for high-speed models​ (up to 120–150 m/min or more) to boost output without sacrificing quality.
​Integration capabilities​ with upstream wire drawing lines or downstream coiling/packaging systems for full production line solutions.
Serving Global Markets with Proven Results
Beyde’s tubular stranding and closing machines are trusted by steel cord and rope producers in ​South America, North America, Europe, Asia, and the Middle East. Our equipment has been successfully applied in:

​Construction & infrastructure​ (pre-stressed concrete strands for bridges and buildings)
​Mining & heavy lifting​ (hoisting ropes, draglines, and towing cables)
​Maritime & offshore​ (mooring lines, towing hawsers)
​Automotive & elevator​ (high-strength steel cords for tires and elevator ropes)

In 2019, due to the continuous increase of orders, the original production workshop could no longer meet the production requirements. Therefore, the management

of the company decided to repurchase a new piece of land of 10,000 square meters, and built the second processing plant in half a year. branch, and recruited 50

skilled workers, led by professional team personnel, and achieved good benefits, greatly relieving the pressure of production.

Beyde company is used for international advanced cable and wire processing equipment. In China, we are the only real manufacturers with independent processing and design capabilities.

The company produces 200-300 cable machines per year, especially pipe stranding machines, accounting for 60% of the Chinese market.
