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.
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
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.
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.

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.
