The new J 20 is another milestone in the development of Rieter air-jet spinning. With 200 spinning units per machine, the J 20 is twice as long as conventional air-jet spinning machines. The unique machine design and innovative automation make this leap in productivity possible. The main advantage of the new J 20 is the reduction in piecing cycle time by one-half. This is achieved by means of the new, automated piecing preparation process, which significantly reduces the robots' workload. The spinning unit itself removes the yarn defect and injects the yarn end through the spinning tip.
