A new integrated yarn tension control system for consistent production results

Rosendahl's ROBI high-speed low-tension cross-binder was designed for binding SZ-stranded loose tubes. Nowdays, the ever-increasing needs of the market push machines manufacturers to always find new technologies and solutions to improve this strading method. That's why Rosendahl developed a new integrated yarn tension measurement system, which allows consistent and, if required, very low binding tension, also during high-speed productions.
Speed is usually a very important factor of performance. With a line speed of up to 200 m/min, loose tubes are stranded at an impressive 2,500 rpm. But speed alone isn't enough to fulfill all manufacturer requirement for a production line. Integrated components also have to react precisely at high speeds.
The introduction of new materials and the optimization of cable designs constantly pose new challenges for cable manufacturers. A few years ago, a loose tube with 12 fibers had a diameter of 2.8 mm. Today, the same loose tube has a diameter of only 1.4 mm. Low binding forces are now a fundamental criterion when stranding such cores.
Tensions of 2 Newtons and less
The newly developed Rosendahl yarn tension binder enables minimum yarn tensions of 2 newtons, which cannot be achieved using conventional binders. These constant tension forcesbring excellent results in fiber optic productions and minimize scrap.
