China Tubular Stranding Machine Suppliers
The tubular stranding machine is designed for high-carbon and low-carbon steel wire ropes, as well as Copper and aluminum conductors. It supports back twist stranding for 1+6, 1+12, 1+18, and 1+6+12 bobbin configurations, suitable for both round and compact copper/aluminum conductors, as well as steel wire stranding.
We offer customized tubular stranding machines based on customer requirements. The machine can be configured with 1+5, 1+6, 1+8, 1+10, 1+12, or 1+18 bobbins, depending on the application. Bobbins are available in various sizes, including 200 mm, 250 mm, 315 mm, 400 mm, 500 mm, 630 mm, 800 mm, 1000 mm, and 1250 mm, following DIN 46397 standards or modified versions.
The tubular cage is supported by high-quality bearings on both ends, with a large main bearing using pump-oil forced lubrication. The cage is annealed to reduce internal stress and extend its service life. This machine is known for its high efficiency, speed, low noise, and long operational life.
Maximum speeds vary by model: up to 1400 RPM for 200/1+6, 900 RPM for 200/1+18, and 100 RPM for 1250/1+5. Bobbins are secured using mechanical pintles—either movable or fixed, or fastened to the axis via latches. Each bobbin is equipped with different braking systems for tension control, and a disk-type pneumatic brake is used for the cage.
The machine can be equipped with PLC control, making it highly automated and efficient.
