Transformation of circular weaving technology through the use of a superconducting weft insertion system

The "SupraWeave" project is dedicated to the fundamental transformation of circular weaving technology through the use of a superconducting weft insertion system. The aim is to use sensitive high-performance fibers such as glass and carbon fibers, which could previously only be processed on flat weaving machines, in circular weaving machines. These fibers are indispensable in industries such as aviation, automotive engineering and energy technology, but their sensitivity and the high mechanical loads of conventional circular weaving processes have so far presented an insurmountable hurdle.

The project's innovation is based on the use of superconducting magnetic bearings. These enable friction-free, precise guidance of a floating contactor, which revolutionizes weft insertion in a completely new way. This technological innovation is complemented by low-damage guidance of the warp and weft yarns, which enables unprecedented material protection. These approaches make it possible to produce circular fabrics with optimum structure and quality that meet the high demands of technical applications.

A key aspect of the project is the development and integration of all components into a demonstrator system that maps the entire process. A holistic development approach is being pursued, from modelling the magnetic bearings and thread guidance to adapting the fabric take-off and manufacturing and characterizing the end products. Particular emphasis is placed on validating the models and algorithms developed in order to ensure that the new technology is highly reliable and efficient.

SupraWeave" not only closes a technological gap, but also lays the foundation for opening up new markets. The production of composite materials and technical textiles for future-oriented applications could be permanently changed by this innovation. The results of the project will enable the Saxon textile and mechanical engineering industry to continue to assert itself as a technology leader in global competition, open up new market segments and make industrial production more sustainable and efficient.
