dimensions of up to 290mm for the outer diameter. This enables continuous production lengths. The integrated mini twist lock keeps strands perfectly formed and supports immediate binding at the stranding point.

ROSENDAHL developed the ROBI high speed cross binder for SZ-stranded fibre optic cable elements. At 4,500 rpm, it is fast, but at the same time very gentle in its handling. It has an adjustable binding

tension to maintain the loose tube shape and the product’s quality. Beyond that, it is specially designed to maintain the very short reversal spots generated by the dynamic drive system of the Rosendahl SZ-strander. You can achieve a constant yarn tension below 2N with the optionally available active yarn tension control system.

❍ The Rosendahl ROBI high speed cross binder

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. Rosendahl Nextrom GmbH – Austria Website : www.rosendahlnextrom.com

This system keeps the tension constant at all operating conditions even while the binder is ramping up/ down and at high production speeds. This allows the user to attain constant and high-precision binding to maintain the product’s properties. Size-wise, ROBI allows large bobbin

Ensuring quality in measurement

There is direct/indirect impact on product quality with tension variation beyond certain limits in processes like extrusion, stranding, bunching, twisting, rewinding, coiling, weaving, coating, inspection, drawing, enamelling or similar. These processes have a direct impact on the quality of the product, as well as machine performance. This results in the end product quality being compromised in spite of the willingness to give the best quality product by the industry. With the help of 25 years’ experience, Puretronics is able to introduce a tension measurement system, which is useful in various applications. In continuous production processes, the quality of the finished products is directly dependent on the accurate measurement and control of the material tension, thus improving finished product quality, reducing waste, increasing processing speeds and minimising machine efficiency and low downtime.
