open end spinning

R 40 – Pioneering innovations - RIETER The productivity potential of the fully automatic rotor spinning machine R 40 with up to 500 spinning positions, delivery speeds up to 359 m/min and rotor speeds up to 160,000 min-1 is unique in the market place. The highest package weights up to 6 kg can be achieved thanks to a package diameter of 350 mm maximum, and offers the optimal prerequisite for minimizing costs in subsequent processing. The newly developed AEROpiecing system in the R 40 results in a significant improvement in the piecing quality compared with previous models. Precise settings on the robot permit a piecing which was previously unobtainable and is optically hardly visible. The outstanding quality of the yarns produced on the rotor spinning machine R 40 has led Rieter to label these with the registered trademark ComfoRo®ComfoRo®. ComfoRo® yarn with the new AEROpiecing technology guarantees high performance in subsequent processing and sound end products.
