SZ-STRANDING for fibre optic cables has been improved.
Rosendahl and Nextrom have elaborated a concept which
coordinates performance and costs in one line.
What has been achieved is a low total cost of ownership
(TCO). This is a result of higher overall equipment
effectiveness (OEE) and longer product lifetime, with fewer
spare part needs. The line itself is designed for a short
set-up time, which also supports increased OEE.
Performance improvement speed is usually a key factor.
With a line speed of up to 200m/min, the loose tubes are
stranded at 2,500rpm.
But speed alone does not fulfil all the requirements a
manufacturer has on a production line. Integrated
components also have to react precisely at high speeds.
The new ROBI cross binder from Rosendahl Nextrom keeps
up with the speed while at the same time securing low
tension for the stranded bundle.
The active yarn tension control ensures that the tension
does not harm the tubes or bundle. When it comes to
thin-wall products, the ROBI demonstrates accurate binding
quality with perfect tension – even when crossbinding soft
tubes or soft bundles.
Currently, the OFC 70/RL-R SZ-stranding line is claimed to
offer the shortest reversal time on the market. The company
can also provide a tailor-made lay plate design depending
on the product mix.
DPT is Rosendahl Nextrom’s solution for space-saving
payoff design for loose tubes. The integration of two payoff
positions in one common machine frame helps to save shop
floor space. The DTP is available in two sizes, either for
spools with up to 800mm or up to 1,000mm flange diameter.
Especially regarding product designs with two or more
layers of stranded tubes, the DPT can reach its full potential
in terms of space savings.
