Winding optical glass fibre at very low twist

maintaining high quality tensions at high speeds from ranges less than 10mN to higher than 4N. Accuracies are possible to better than ±1mN according to material and type. The CMW is also used where highly accurate, consistent speed control and tension are paramount in re-winding systems or similar processes. As each winder can be used as payout or take-up, as master or slave, at the touch

supervision or operator intervention. In spite of this simplicity, the specially developed Supertek electronic control systems allow software-controlled setup for all system parameters, many adjustable ‘on the fly’. Optical fibres demand a highly accurate and consistent winding and process tension control. This is covered by the Supertek electromagnetic dancer system. This novel system is capable of

Unavoidable optical glass fibre twisting caused by spooling processes can result in unacceptable EMR transmission quality degradation. However, increasing optical transmission and laser coherent beam requirements demand ever-increasing transmission quality. German company Supertek has worked on this problem for some years and can now offer solutions providing very low twist values, in most cases well under

of a button and is fully process- programmable, this real multi -talent can be used in almost any desired configuration. All the features apply not only to optical fibres. The digitally controlled traversing spool winder system is also suitable for materials such as plastics, rubbers, carbon fibres, medical plastics, membranes, chemical fibres, precious metals and alloys as well as simple steels, coppers and other metals, textiles or chemical products.

0.5 turns per 2m length, whilst still maintaining the highest standards in winding, laying and tension control. The use of the Supertek Compact Multi-Winder (CMW) full- or semi-automatic system allows all optical fibre requirements to be handled simply and highly accurately from drawing tower output to all other following processes. Precision tension control and laying geometry, fibre line handling at speeds up to > 3,500m/min, and all with the absolute minimum of
