Ultra-fast winding

Designed to achieve superior construction for ultra-fast winding of all types of thin yarns and fibres, with a particular focus on fiberglass thread manufacture, SMW guarantees its Finfibre and Yarnbe models to successfully exceed in rotational velocity any other bobbin holder on this planet. As a result, these rotors allow for production of thinner threads, leading to more advanced applications – higher-quality fabric, prepregs and so on.
