Roth unveils duplex filament winding machine with double power

With an innovative machine concept, Roth Composite Machinery says it is setting new standards in mechanical engineering for the manufacture of products using the filament winding process.

The company now offers the Filament Winding Machine FWA 1 Duplex which enables the winding process from both sides of a spindle, and as a result, halves the production times compared to standard machines.

“After successfully launching a system to speed up filament winding processes by a multiple with the development of the Rothawin technology, we are presenting another innovation,” stated Dr Andreas Reimann, general manager of Roth Composite Machinery. “Our new FWA 1 Duplex Machine for the large-scale production of pressure vessels - particularly for the automotive industry - achieves double the productivity compared with our current world-leading standard.

“While the production lines based on the Rothawin technology aim at the manufacture of small compact vessels primarily used for cars, the new gantry machine generation addresses the highly productive manufacture of vessels for commercial vehicles and trucks. Compared to our conventional multi-spindle machines, the production process is 10-15% faster. A particularly strong frame construction with an additional spindle drive on the opposite side keeps this dynamic and, in addition, the doubled fibre volume under control with ease.”

The design of the Duplex production line stands out with a space-saving of up to 15% and enables a more effective utilisation of the production floor. Furthermore, the new Filament Winding Machine is about 10% cheaper compared to other machinery with the same output capacity. It is available with three, four or five spindles, as well as an additional carriage system as an option. The machine is suitable for production processes of wet, dry or towpreg winding procedures by using all common types of fibres, especially carbon and glass fibres.
