ROBI: High Speed and Low-tension Cross Binder for Single and Dual-end Yarns

Rosendahl has developed low-tension cross binder with up to 4500 rpm for producing a well-shaped product and continuous production lengths even with large bobbins.

ROBI allows large bobbin dimensions of up to 290 mm for the outer diameter, enabling continuous production lengths.

The high speed cross binder, the ROBI is developed by Rosendahl for SZ-stranded fiber optic cable elements. With a speed of 4500 rpm this cross binder is fast but has an adjustable binding tension to maintain the loose tube shape and your product’s quality. It is specially designed to maintain the very short reversal spots generated by the dynamic drive system of the Rosendahl SZ-strander. It is possible to achieve a constant yarn tension below 2 N with the optionally available active yarn tension control system from Rosendahl. This system will keep the tension constant at all operating conditions even while the binder is ramping up/down and at high production speeds.

As far as size is concerned, ROBI allows large bobbin dimensions of up to 290 mm for the outer diameter, enabling continuous production lengths. The integrated mini twist lock keeps strands perfectly formed and supports immediate binding at the stranding point. Essential parameters, such as bobbin weight, bobbin diameter and brake curve, are stored in the database. These parameters are used during line operation to maintain a constant yarn tension at various production speeds. Therefore, you get a well-shaped product and continuous production lengths at high speeds.
