480 is equipped with up to 4 Coromat unit per machine The Corobox SE12- a universal SpinBox for all types of. .. running times of the bobbin at the roving frame and at the ring spinning machine reduce the number of bobbin changes This is very beneficial during producing coarse yarns, particularly in the field of denim Zinser 351-cotton ring spinning machine Zinser 351, which is ideal for denim applications, are equipped with ServoDraft (electronic drafting system drive), New CoWeMat (automatic doffer) and OptiSuction... in denim yarn production The rotor speed in latest machine exceeds 150,000 rpm and the take-up speed 300 m/min Package weights up-to 5 to 6 kg can be made in latest machine which subsequently helpful to increase the productivity in subsequent process in denim production Predetermined length of yarns are wound on to the packages with great accuracy which reduce the wastage in ball warping in case of. .. servo motor starts only at the time of slub formation and additional speed is given to the drafting system, which disturb the normal yarn formation In case of open end spinning, the slub yarn is produced in the same principle which is explained with the
