Murata has developed MVS 810, MVS 81T, MVS 851, MVS 861 and lastly the MVS 870 model spinning machines. Murata MVS 810 was the first vortex spinning machine exhibited at Osaka International Textile Machinery Show in 1997 (OTEMAS ’97). The machine had a delivery speed of up to 400 m/min. The modified version of this machine, MVS 81T, was developed to produce twin vortex spun yarns. The yarns spun on two spinning units pass through the same yarn cleaning and waxing unit and are wound on the same package. These are twisted on a two-for-one twister to obtain a plied vortex yarn. Subsequently, Murata introduced the MVS 851 spinning machine. Apart from the previous machine, MVS 851 is not capable of spinning core yarns. Murata exhibited a new version of vortex spinning machine, the MVS 861, in 2003. This version allows the core yarns production with higher delivery speed of up to 450 m/min. The spinning system ensures uniform winding tension with a tension ruler with minimum energy consumption [3, 4]. Figure 2 displays the general view of the MVS 861 machine and the yarn spinning unit.
